Just like solving problems, crafting good questions requires you to put in some effort!&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Ask a focused question that has a specific goal&lt;/li&gt;&#xA;&lt;li&gt;Be precise&lt;/li&gt;&#xA;&lt;li&gt;Do your homework&lt;/li&gt;&#xA;&lt;li&gt;Break it down&lt;/li&gt;&#xA;&lt;li&gt;Consider different formulations of the question&lt;/li&gt;&#xA;&lt;li&gt;Provide background and motivation&lt;/li&gt;&#xA;&lt;li&gt;Make your title your question&lt;/li&gt;&#xA;&lt;li&gt;Format your question well&lt;/li&gt;&#xA;&lt;li&gt;Additional resources&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;h2&gt;Ask a focused question that has a specific goal&lt;/h2&gt;&#xA;&#xA;&lt;p&gt;It should be absolutely clear what constitutes an answer to your question. Here are some examples of vague and specific questions. For each one, ask yourself, &lt;em&gt;&quot;If I saw an answer to this question, could I confidently determine whether it tells the asker what she actually wants to know?&quot;&lt;/em&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Too vague/broad&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;What can I deduce from X? &lt;/li&gt;&#xA;&lt;li&gt;What is known about the X conjecture?&lt;/li&gt;&#xA;&lt;li&gt;What are all the ways to do X?&lt;/li&gt;&#xA;&lt;li&gt;Tell me about elliptic curves.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Focused&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Does X imply Y?&lt;/li&gt;&#xA;&lt;li&gt;Is there an example of X such that Y?&lt;/li&gt;&#xA;&lt;li&gt;Is the X conjecture true in situation Y?&lt;/li&gt;&#xA;&lt;li&gt;Is there a way to do X other than Y (which I can't use because Z)?&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Note that being specific does &lt;strong&gt;not&lt;/strong&gt; mean plugging in specific numbers or otherwise making your problem look like an exercise in a book. It means asking a to-the-point question that &lt;strong&gt;has an answer&lt;/strong&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you can't turn your question into a specific one, ask yourself what you hope to gain by asking the question. What concrete goal are you moving towards? If you can't think of one, then please don't ask the question. If you just want to know more about some area, read a book or an article or the Wikipedia page or Google for it. Either you'll learn about the subject effortlessly, or at some point you'll get stuck on some very concrete thing. If the former happens, good for you! If the latter happens, then the MathOverflow community is here to help you get unstuck. If you have a concrete goal, but your question is extremely broad, break it down into more focused questions.&lt;/p&gt;&#xA;&#xA;&lt;h2&gt;Be precise&lt;/h2&gt;&#xA;&#xA;&lt;p&gt;Being precise means communicating the parameters of your question so that others know where to start answering it and know when they've given you a complete answer. Of course, the includes stating the hypotheses and goal of your problem. If you suspect that you're asking an elementary question outside of your field, you may also want to explain your background a bit. This makes it easier for the person answering your question to know what she can take for granted.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is especially important for &quot;soft&quot; questions and &quot;big list&quot; questions to be precise. Otherwise they'll be boring and useless. &lt;em&gt;&quot;What are the best number theory books&quot;&lt;/em&gt; is a bad question. Best for what? Assuming what background? A better version of the question might be &lt;em&gt;&quot;What are the best textbooks for an undergraduate number theory course?&quot;&lt;/em&gt; or &lt;em&gt;&quot;After an undergraduate number theory course, what should I learn if I want to study elliptic curve cryptography?&quot;&lt;/em&gt; These questions aren't great, but they make it clear what the starting point is and what the goal is.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Make sure it's clear exactly what your question is. It's extremely frustrating to read a long question which explains what the general problem is but doesn't contain an actual question. I usually resort to searching the body of the post for question marks, but it often doesn't help. After defining all your terms and motivating your question, consider visually distinguishing the final version of the question (see the formatting section).&#xA;&lt;br&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are few things worse than a question which is too vague, too broad, or imprecise. Not only is it lazy to ask a vague or imprecise question, it's also rude. You're essentially asking somebody to do the work of figuring out what you want to ask, and then answer it, or to answer several possible interpretations of your question. Suppose somebody asks, &lt;em&gt;&quot;What do you guys think about Foobar's new paper?&quot;&lt;/em&gt; Even if this is exactly in my field, and I understand Foobar's paper better than Foobar himself, I have no idea where to start answering a question like that. Compare to, &lt;em&gt;&quot;Does Foobar's regularization construction solve the Baz-Flipt Conjecture?&quot;&lt;/em&gt; As an expert, this is something I can actually answer.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;When you're browsing MO, please don't vote up unfocused or imprecise questions. Such questions are as bad as (or worse than) homework questions; they waste everybody's time. If somebody asks, &lt;em&gt;&quot;What's the deal with algebraic geometry?&quot;&lt;/em&gt; you might say to yourself, &lt;em&gt;&quot;Wow, I'd really love to see a great answer to that one. I'm going to vote it up.&quot;&lt;/em&gt; &lt;strong&gt;But don't!&lt;/strong&gt; You're encouraging the wrong behavior. The great answer you're hoping for doesn't exist because there isn't a precise question. At best, somebody will answer, &lt;em&gt;&quot;go read a survey article or a standard reference or the nLab page or the Wikipedia page.&quot;&lt;/em&gt; Worse, somebody who is too kind and too generous with her time may spend a great deal of time and energy crafting an answer that might not satisfy the asker and that will be just a shadow of a proper survey paper. Such questions can't be reasonably answered in a few hours, even by an expert who knows the &quot;answer.&quot;&lt;/p&gt;&#xA;&#xA;&lt;h2&gt;Do your homework&lt;/h2&gt;&#xA;&#xA;&lt;p&gt;Before asking your question, try to solve it. Search &lt;a href=&quot;http://google.com&quot; rel=&quot;nofollow&quot;&gt;Google&lt;/a&gt;, &lt;a href=&quot;http://en.wikipedia.com&quot; rel=&quot;nofollow&quot;&gt;Wikipedia&lt;/a&gt;, and &lt;a href=&quot;http://ncatlab.org/nlab/show/HomePage&quot; rel=&quot;nofollow&quot;&gt;nLab&lt;/a&gt;, check any references you can think of, and try to figure the problem out yourself (maybe even sleep on it). Doing so will help you break the problem down and understand it better. Even if you don't solve the problem, putting some work into it will often help you understand exactly what it is you're having trouble with, so you'll be able to ask a better question.&lt;/p&gt;&#xA;&#xA;&lt;h2&gt;Break it down&lt;/h2&gt;&#xA;&#xA;&lt;p&gt;You may have a specific problem you're trying to solve, and you may have done your research, but the problem might be a monster. Even if it's not a monster, you'll probably benefit from trying to break the problem into smaller pieces and posting one or two of the pieces on MO. To modify a quotation of P&amp;oacute;lya, &quot;If there is a problem you can't solve, then there is an easier problem you can't solve: find it.&quot; You may worry that the the pieces are not interesting enough or are too specific to post on MathOverflow, but you shouldn't. It's much better to post a question that is too focused than to post a question that is too vague or too broad.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It's okay to ask several questions related to a project you're working on, but try to limit yourself to one or two per day. Rather than posting all the parts of your problem at the same time, work through them one at a time. After all, the solution to one part may completely change your plan for solving the problem.&lt;/p&gt;&#xA;&#xA;&lt;h2&gt;Consider different formulations of the question&lt;/h2&gt;&#xA;&#xA;&lt;p&gt;Sometimes your question is boring, but you can often make it much more interesting by recontextualizing it.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It could be enough to just ask if your question is false. For example, you might be reading a book when you come across &lt;em&gt;&quot;Theorem 2.1. Every regular doodad is a widgit.&quot;&lt;/em&gt; You read the proof, but you don't understand where it uses the hypothesis that the doodad is regular. Your question is &lt;em&gt;&quot;Where does the author of this book use the regularity hypothesis in Theorem 2.1?&quot;&lt;/em&gt; That is a boring question! But answering it is equivalent to answering an interesting question, &lt;em&gt;&quot;Is every doodad a widgit?&quot;&lt;/em&gt; That is, does the result remain true if you remove (or weaken) the hypothesis? Ask the more interesting question, and add &lt;em&gt;&quot;I ask because I'm reading the proof of Theorem 2.1 of this book, which shows that regular doodads are widgits, but it looks like it doesn't use the regularity hypothesis.&quot;&lt;/em&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Another thing you could try is to broaden the appeal of your question by generalizing it. Generalizing is actually a way of breaking the question down, since it amounts to removing hypotheses. For example, you might be trying to prove that some particular object X is a widgit. Asking &lt;em&gt;&quot;Is X a widgit?&quot;&lt;/em&gt; might not be a very interesting question. So you do your homework by looking for references and by trying to prove it in various ways. Eventually, you realize that the basic property of X that should force it to be a widgit is that it is a doodad, so you ask yourself, &lt;em&gt;&quot;Is every doodad a widgit?&quot;&lt;/em&gt; Of course not; it's easy to come up with doodads that aren't widgits. There must be some other property of X that will allow you to prove it's a widgit. Maybe it's because X is a &lt;em&gt;regular&lt;/em&gt; doodad. After thinking about it for a while, you think that it's plausible that every regular doodad is a widgit. If you can't come up with a proof or a counterexample, then you could ask, &lt;em&gt;&quot;Is every regular doodad a widgit?&quot;&lt;/em&gt; If you do, you may want to explain in a background/motivation section that you're really trying to show that X is a widgit.&lt;/p&gt;&#xA;&#xA;&lt;h2&gt;Provide background and motivation&lt;/h2&gt;&#xA;&#xA;&lt;p&gt;MathOverflow isn't just a place to ask and answer questions. It's also a place to read questions and answers, which is a great way to see what people in other fields think about, and to see how they actually think about it (not just what the polished papers look like). So when you ask for the help of those who know more than you, please also extend a hand to those who know less than you by explaining why you are asking the question. You'll get more votes, generate more interest, and are more likely to get your question answered. Explaining the motivation for a question may also help you gain a fresh outlook on the topic you're asking about. MO is meant to develop your ability to do mathematics, but also to develop your ability to communicate it.&lt;/p&gt;&#xA;&#xA;&lt;h2&gt;Make your title your question&lt;/h2&gt;&#xA;&#xA;&lt;p&gt;Use your title to convey as much information about your question as possible. Since the tags already convey the general subject area of your question, the title should communicate the question itself as faithfully as possible. If necessary, leave out hypotheses in the title, and in the body of the question, explain why the question requires those hypotheses.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Don't be afraid to make your question title long. Titles are allowed to be anywhere from 15 to 250 characters long. 140 characters (the length of a tweet) takes up about two full lines on the home page, so try to keep it less than that. But 140 characters is a lot longer than you might think. Too many people restrict themselves to 20 character titles. They're trying not to waste your time by making you read a long title, but they end up wasting more of your time because you have to actually open the question to see if it's interesting to you.&lt;/p&gt;&#xA;&#xA;&lt;h2&gt;Format your question well&lt;/h2&gt;&#xA;&#xA;&lt;p&gt;The readability of your question can often be greatly improved if you learn to use &lt;a href=&quot;/editing-help&quot;&gt;formatting commands&lt;/a&gt;, especially if your question ends up being quite long. Here is an example that contains a few good uses of the formatting commands:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;code&gt;## Background/Motivation&lt;/code&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;code&gt;A *doodad* is a thingumabob together with a sheaf of doohickies (which is usually called the *doo structure* on the doodad). A doodad is said to be *regular* if the sheaf of doohickies is regular. Intuitively, regularity makes a doodad &quot;rigid&quot; since information about the doo structure at a point can be translated into information about the doo structure at nearby points.&lt;/code&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;code&gt;A *widgit* is a whatsit which is flat (in the sense that its Plotsky curvature is zero). Showing that a space has a widgit on it is extremely useful because the flatness allows you to apply Foobar's gadget construction to prove many useful results about the space.&lt;/code&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;code&gt;----&lt;/code&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;code&gt;Based on the above intuition, it is natural to ask if every doodad is a widgit. However, the answer is clearly no, since a widgit is always regular, but [some example] is a non-regular doodad, so it is clear that we must impose a regularity hypothesis.&lt;/code&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;code&gt;&amp;gt; Is every regular doodad a widgit?&lt;/code&gt;&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;h2&gt;Background/Motivation&lt;/h2&gt;&#xA;  &#xA;  &lt;p&gt;A &lt;em&gt;doodad&lt;/em&gt; is a thingumabob together with a sheaf of doohickies (which is usually called &gt;the &lt;em&gt;doo structure&lt;/em&gt; on the doodad). A doodad is said to be &lt;em&gt;regular&lt;/em&gt; if the sheaf of &gt;doohickies is regular.

The words being defined are italicized.

Looking at it, there are many options and some hard stats on how many of each type of post would be useful. I suggest that you wait for a month (or two), check the migration stats (available to 10k+ users), and make individual meta posts for each migration path you want.&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Chatroom Etiquette and owners&lt;/strong&gt;: It's not yet clear if &lt;a href=&quot;http://chat.stackexchange.com/rooms/9369/mathoverflow&quot;&gt;chat&lt;/a&gt; is going to be used much. I personally suggest that you do try it out -- it's a great place to informally discuss various things, both on and off topic. If you do indeed decide to use it, I suggest you draft out a chatroom etiquette post &lt;a href=&quot;https://math.meta.stackexchange.com/questions/3890/main-chatroom-etiquette-rules&quot;&gt;like this one&lt;/a&gt;. A lot of folks have expressed concerns over chat being flooded by homework; you may want to explicitly make it off topic for chat (and thus homework askers can be easily kicked, and chatbanned if persistent). You may also want to appoint room owners from the regulars so that they can help moderate chat.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Request a blog&lt;/strong&gt;: (See &lt;a href=&quot;http://blog.stackexchange.com/2011/06/blog-overflow/&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://blog.stackexchange.com/2011/06/blog-overflow/&lt;/a&gt; and &lt;a href=&quot;http://stackexchange.com/blogs&quot;&gt;a list of current blogs&lt;/a&gt;) Another cool SE feature is that sites can collaboratively run their own blog. If you feel that there are enough people in the community who will be able to maintain a steady stream of posts, start a meta post about this, asking if the community thinks that it's a good idea and fielding for volunteers. (More details on the process &lt;a href=&quot;http://blog.stackexchange.com/2011/06/blog-overflow/&quot; rel=&quot;nofollow noreferrer&quot;&gt;here)&lt;/a&gt;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Request Question/Answer bans&lt;/strong&gt;: (See &lt;a href=&quot;https://stackoverflow.com/help/question-bans&quot;&gt;https://stackoverflow.com/help/question-bans&lt;/a&gt;).

The right thing to do is to &quot;skip&quot;. But the system is gamefied in such a way as to incentivise taking action anyway. If a question or answer &quot;looks&quot; bad but is actually good, I'm pretty sure that this system significantly increases the risk of incorrect closure (perhaps even deletion); especially as other people's votes are not visible.

We're happy to have y'all here.&lt;/p&gt;&#xA;&#xA;&lt;hr/&gt;&#xA;&#xA;&lt;p&gt;Far as migration paths go, we'd be happy to set up up to 4 defaults for you guys, but there are a few considerations we usually take into account. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;First of all, migrations paths are only available for &lt;em&gt;graduated&lt;/em&gt; sites. This means that sites like &lt;a href=&quot;http://academia.stackexchange.com&quot;&gt;Academia&lt;/a&gt;, &lt;a href=&quot;http://scicomp.stackexchange.com&quot;&gt;Computational Science&lt;/a&gt;, &lt;a href=&quot;http://cs.stackexchange.com&quot;&gt;Computer Science&lt;/a&gt;, and &lt;a href=&quot;http://philosophy.stackexchange.com&quot;&gt;Philosophy&lt;/a&gt; are currently not an option for user-driven migrations. This is done to minimize the chances of newer sites and/or sites that have yet to cement their long-term success from being potentially overwhelmed with effectively rejected question from other sites in the network. We ideally want every beta to form its own voice.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In a pinch, diamond moderators have the ability to migrate a question to any site in the network (so long as it's not in the private beta stage), but this is ideally only done for exceptionally good questions and not just anything that could conceivably be asked somewhere.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Secondly, &lt;a href=&quot;http://math.stackexchange.com&quot;&gt;Mathematics&lt;/a&gt; is an obvious choice and it's already enabled, but beyond that I would like to suggest letting MathOverflow run as is for at least a few weeks to see what sort of questions you keep getting and what sites they get migrated to. We collect statistics on how many questions are migrated, where they end up, and whether or not those migrations are rejected by the destination site. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;(Aside: migrations are considered to be rejected by the destination site when migrated questions are closed as anything other than &quot;duplicate&quot; or deleted. This is another flood prevention mechanism.)&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In a few weeks/months, we all will have a better handle of what migration paths make the most sense and are most successful. In the meantime, you can request a migration by flagging a question and explaining what you'd like to happen, and a moderator will make the call whether to move it over to another site or not. We'll be happy to set up user-driven migration paths when we see clear patterns for migrated questions both in terms of quantity and quality (i.e. low rejection percentage).&lt;/p&gt;&#xA;" OwnerUserId="35318" LastEditorUserId="-1" LastEditDate="2017-03-20T10:31:57.100" LastActivityDate="2013-06-26T04:12:30.263" CommentCount="9" ContentLicense="CC BY-SA 3.0" />

There was an intelligent comment from Neil Strickland, and also a comment that it's an imprecise question and should therefore be closed.  Obviously anyone maintaining that imprecise questions have generally been unwelcome on mathoverflow would lose any debate about whether that's true.  Maybe the other point is more substantial.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;b&gt;Postscript:&lt;/b&gt; Angelo draws parallels to the proposition that every question about zero sets of polynomials is on topic.

I've just notified them by email.  However, the fact that mathoverflow's notification system has no way to handle such a matter is a flaw.

Just this morning I derived a simple result: The function $\theta\mapsto\tan(\theta/2)$ is the identity element in a structure that one naturally considers when thinking about this question.  Maybe high-school-level in the sense that if one phrased it as a precise question, a bright high-school student would prove it.  But I wouldn't be surprised it hasn't been noticed before.  And it would take an even brighter high-school student to think of asking that question.  Which raises a question that I'll ask on &quot;main&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;b&gt;PPPPS:&lt;/b&gt; One should ask a &quot;focused question&quot; with a &quot;specific goal&quot;.

One off simple questions are fine, such as &quot;&lt;em&gt;Do you folks mind sanity checking something for me? I can't believe I'm getting this result&lt;/em&gt;&quot; - or similar. If a question is sufficiently involved that a protracted response is warranted, chat is the wrong place to be asking, regardless of the topic.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Think of chat as something of a pub, where you arrive to a group of your peers engaged in a lively conversation.

These can be questions that arise when you are working on or preparing to work on a mathematical research-problem, but they also may be questions that you come across when you are reading scholarly journals or advanced graduate level books in mathematics. A question does not have to be about new mathematics. A typical example is, &amp;quot;Can this hypothesis in that theorem be relaxed in this way?&amp;quot;&lt;/p&gt;&#xA;&lt;p&gt;The site works best for &lt;strong&gt;well-defined questions&lt;/strong&gt;: math questions that actually have a specific answer. You'll notice that there is the occasional question making a list of something, asking about the workings of the mathematical community, or something else which isn't really a math question. Such questions can be helpful to the community, but it is extremely tricky to ask them in a way that produces a useful response. So if you're new to the site, we suggest you stick to asking precise math questions until you learn about the quirks of the community and the strengths of the medium.

If a question is closed, it's probably because it fell into one of these categories.

Though there are no hard and fast rules about who may post here, the intended audience is professional mathematicians, mathematics graduate students, and advanced undergraduates. If your question is closed as &amp;quot;off topic,&amp;quot; it might be because it was too elementary.

If your question was closed as &amp;quot;too localized,&amp;quot; it was probably an explicit homework problem (or looked like one).

MathOverflow visitors should know how to learn new things and do mathematics on their own, but we all get stuck sometimes, and this is where MO saves the day. When you're stuck, you can come to MathOverflow and say &amp;quot;I'm trying to do X. How can I do that? Does this work? Does anybody have a reference?&amp;quot; The idea being that for an expert, it should take very little effort to understand your confusion and set you on the right path. Or maybe a non-expert has come across the same sticking point and can explain how she resolved it. MathOverflow is not the appropriate place to ask somebody to write an expository article for you. If you want somebody to write an article about some subject, you should make a stub on &lt;a href=&quot;http://www.wikipedia.org/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Wikipedia&lt;/a&gt;, make a &lt;a href=&quot;http://ncatlab.org/nlab/show/FAQ#where_do_i_ask_a_question_13&quot; rel=&quot;nofollow noreferrer&quot;&gt;query block on nLab&lt;/a&gt;, or make a &lt;a href=&quot;http://planetmath.org/?op=reqlist&quot; rel=&quot;nofollow noreferrer&quot;&gt;request on PlanetMath&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&#xA;&lt;strong&gt;MathOverflow is not for questions about MathOverflow.&lt;/strong&gt; Mathematicians don't come here to learn about the intricacies of this site; they come here to get answers to their questions.

Save that for the 30,000+ character Markdown tag wiki. The excerpt should define the shared quality of questions containing this tag — boiled down to a few short sentences.&lt;/p&gt;&lt;/li&gt;&#xA;  &lt;li&gt;&lt;p&gt;&lt;strong&gt;Avoid generically defining the concept behind a tag, unless it is highly specialized.&lt;/strong&gt; The “email” tag, for example, does not need to explain what email is. I think we can safely assume most internet users know what email is; there’s no value in a boilerplate explanation of email to anyone.&lt;/p&gt;&lt;/li&gt;&#xA;  &lt;li&gt;&lt;p&gt;&lt;strong&gt;Concentrate on what a tag means to &lt;em&gt;your&lt;/em&gt; community.&lt;/strong&gt; For “email” on Server Fault, mention the server aspects of email including POP3, SMTP, IMAP, and server software. For “email” on Super User, mention desktop email clients and explicitly exclude webmail, as that would be more appropriate for webapps.stackexchange.com.&lt;/p&gt;&lt;/li&gt;&#xA;  &lt;li&gt;&lt;p&gt;&lt;strong&gt;Provide basic guidance on when to use the tag.&lt;/strong&gt; In other words, what kinds of questions should have this tag? Tags only exist as ways of organizing questions, so if we don’t provide proper guidance on which questions need this tag, they won’t get tagged at all, rendering the tag excerpt moot. Think of it as a sales pitch: in a room full of tags screaming “pick me!”, what would convince a question asker to select your tag?&lt;/p&gt;&lt;/li&gt;&#xA;  &lt;li&gt;&lt;p&gt;&lt;strong&gt;Some tags are common knowledge.&lt;/strong&gt; Most tags require a bit of explanation in the excerpt, even if it’s only 3 or 4 words. But if the tag is common knowledge — that is, if you walked up to any random person on the street and said the tag word to them, and they would know what you were talking about — then don’t bother explaining the tag at all. Stick to usage of the tag within your community in the excerpt. &lt;/p&gt;&lt;/li&gt;&#xA;  &lt;/ul&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;From &lt;a href=&quot;http://blog.stackoverflow.com/2011/03/redesigned-tags-page/&quot;&gt;Redesigned Tags Page&lt;/a&gt; on &lt;a href=&quot;http://blog.stackoverflow.com&quot;&gt;SE Blog&lt;/a&gt;.&lt;/p&gt;&#xA;" OwnerUserId="7507" LastEditorUserId="7507" LastEditDate="2013-06-27T02:52:09.400" LastActivityDate="2013-06-27T02:52:09.400" CommentCount="1" CommunityOwnedDate="2013-06-27T02:44:34.477" ContentLicense="CC BY-SA 3.0" />

This feature might be something that one could add. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;To sort of answer my own suggestion. A counter-argument, as @all was removed and only one @ per comment is valid, might be that neither does one wish to have a somewhat bulk-ish notifier for all voters (of a given type) nor does one want to encourage five comments being posted to notify each individually. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Perhaps, it is not that feasible idea in the end. But, at least I learned something via my suggestion. Thanks to Manishearth and Kaveh for information.  &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;While the question grew out of a somewhat complicated situation and thus might not be presented in an optimal way, I think it touches a very valid point. I do not fully share the specific suggestion of automatic notification when a meta-thread is created, it feels a bit complicated, might not always be necessary and is also somewhat limiting (see below). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The main issue it raises in my mind is whether &lt;em&gt;who&lt;/em&gt; can be notified via an @ is sufficient/optimal? (I do not yet fully oversee this notification-system so I might say something that is not true, I welcome corrections.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As far as I understand one can notifiy users that commented and OP is automatically notified. But, I think it could be useful to be able to notify &lt;em&gt;everybody that interacted with a post in a substantive way&lt;/em&gt;, that is also users that edited, closed (does one now say, had put it on hold?) or reopened it. Or, to put this differently: &lt;em&gt;users that show up in the revision-history of the post.&lt;/em&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I can easily imagine situations where it could be useful to be able to ping somebody that made an edit to a post to get some clarification about a choice they made when doing so, for example. Also to be able to draw the attention from closers or reopeners to some debate could be useful, or also just to ask them specifically in cases of doubts what was the moticatiing reason could be useful.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I cannot really follow Manishearth explication that it does not matter so much who debates and also that people will notice the comment on main or the question on meta. By the same token on could question the usefulness of the entire notification system, since also a follow-up comment can just be noticed or answered by somebody else (and we lived quite well without notifications until very recently on MO). Yet, if one thinks that the possibility to notify is convenient (as I do), then I do not see why one should not also be able to notify a user that edited or closed (in addition to thos that commented).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Thus, I would like to present my slight modification of Michael Hardy's feature request: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Add the possibility to notify those users (via @) that show up in the revision history of a post (that is, users that edited or contributed to a completed closing or reopening).&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I hope this would allow to address the problem Michael Hardy raised, and could also be useful in other ways, such as being able to ask for clarifications related to an edit. &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorDisplayName="user9072" LastEditDate="2013-06-28T01:10:03.253" LastActivityDate="2013-06-28T01:10:03.253" CommentCount="10" ContentLicense="CC BY-SA 3.0" />

I noticed a certain user placing a lot of bounties recently, including one on a question of mine which already had an accepted answer with over 30 upvotes. Even stranger, the person who wrote that answer and the person placing the bounty are the same. This happened on another question as well. Here are the questions I'm talking about: &lt;a href=&quot;https://mathoverflow.net/questions/129762/what-arithmetic-information-is-contained-in-the-algebraic-k-theory-of-the-intege&quot;&gt;1&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/130636/how-to-get-3-manifold-knots-from-number-fields&quot;&gt;2&lt;/a&gt;. I don't really know what's going on with this particular user, because she had some strange bounty behavior earlier in the week related to questions of Porton. Perhaps she's playing around to learn the system better. But it raised two questions for me.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;First, what happens when a bounty of the sort above expires? I assume her answer will win, because it's already the optimal answer. So she'll get back the reputation she wagered and also whatever happens to you when you win a bounty (badges I guess). So in the end the bounty won't produce any new math and won't lead to a transfer of reputation from one user to another. It will however lead to more publicity for the question and answer, and that leads to lots of upvotes. Hence my second question: is this the sort of thing we want happening on MathOverflow? The same thing happens on a lesser scale when someone edits an old question, but the front-page turnover rate is fast so those only stay for an hour or two. Also, there's a disincentive because if you bump your old question/answer too many times it'll become CW. But a question with a bounty stays advertised for a whole week. I feel like using bounties to promote your best answers from the past is a misuse of the system, and I wonder if others agree and if there's anything we can do to dissuade that method of using bounties.&lt;/p&gt;&#xA;" OwnerUserId="11540" LastEditorUserId="8250" LastEditDate="2017-12-24T10:40:00.300" LastActivityDate="2017-12-24T10:40:00.300" Title="Placing bounties on questions which already have a good answer" Tags="|discussion|feature-request|bounty|" AnswerCount="2" CommentCount="6" ContentLicense="CC BY-SA 3.0" />

I think (and I think others share this view) that reputation is just there to make the system work (analogous to funding money for research) and provide some feed back, but other than it does not really mean much (though I have seen it causing some participation addiction). I personally found statistics like &lt;a href=&quot;http://data.stackexchange.com/theoreticalcomputerscience/query/106250/average-quality-of-answers-by-users?MinAnswers=10&quot; rel=&quot;nofollow noreferrer&quot;&gt;average total votes for answers&lt;/a&gt; more interesting. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think if we have a better understanding of the reason some dislike reputation, we may find solutions that work for them without altering the system.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;First, let me point out that even if there was a reputation opt-out it would still be possible for others to calculate how much reputation you have (and it is not really difficult using the SE API). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If the issue is that seeing your or other users' reputation bothers or distracts you then you can use userscripts to hide them. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If the issue is that you don't want to have the privileges that come with reputation then you can donate your reputation on questions you like. This is particularly fun with the new bounty system which allows you to select the reason for your bounty. For example, you can put a bounty to award it to some already existing extraordinary answer.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Edit:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;After reading &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/1622&quot; rel=&quot;nofollow noreferrer&quot;&gt;this discussion over tea&lt;/a&gt; I think I partly understand the motivation. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&quot;I answer questions under random user names so people actually have to engage with the mathematical content rather than simply vote based on name recognition.&quot; &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;However, it seems to me it is very difficult to have the following two at the same time: &lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;retain the ownership of posts, &lt;/li&gt;&#xA;&lt;li&gt;not have any publicly accessible history of behavior. &lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;I think the issue is not really reputation, at least not in this case, but not having any public history so the posts are judged purely based on their content. Users who don't care about 1 already can post completely anonymously.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think we can request a feature where the information about the owner of a post is not publicly accessible (but it will be to moderators and maybe also to trusted users).

I don't know if SE would find it a reasonable feature-request, but it might worth discussing/asking for such a feature.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;A negative side of posting anonymously would be lack of meaningful interpersonal interaction, I mean think about a math conference where people are wearing masks to remain anonymous to keep the focus on math.

Turn out was not overwhelming but not as minimal as the score could suggest. Thanks to everyone who participated. At the time of writing we have +4 vs -4. So, opinions are mixed. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;My personal conclusion: since there is no &lt;em&gt;clear&lt;/em&gt; consensus against this edit (if I were to include my opinion in the count there would be a minimal majority against it though), I intend to &lt;em&gt;approve&lt;/em&gt; (somewhat against my very personal opinion) such edits in the future (I did not reject much during the last week either), and by extension most suggested edits (except of course if there is some actual problem with the edit). The reasoning being that sometimes such edits being approved and sometimes such edits being rejected should be an annoyance for those suggesting them in good faith. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If somebody would still like to express their opinion, feel free to continue voting. I will continue to watch the score as I am generally curious about existing opinions. &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;I would like to revisit this matter with an example. (I am not sure if I rather should edit my existing answer or ask a new question but anyway.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It seems to me there is no real consensus reached at all. There is one highly voted answer, however, it is very unspecific so that everybody can read it their way. (I did not get any reply for my request for clarification on what the poster, Andres Caicedo, meant; let alone finding out what the voters mean.) The bandwidth of in my opinion reasonable interpretations ranges from editing should be done if &lt;em&gt;an only if&lt;/em&gt; something displays in an actually wrong way to every improvement however small is an improvement and should be done. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Yet, from my observation and his comment-reply to Yemon Choi I think that Andres Caicedo's and my views are actually not that incompatible, somewhat in the middle of the bandwith in that actual correction should be done and the rest if there is significant room for  improvement (increasing readablity and clarity in a noticeable way), the answer does however leave much room for interpretation. Thus this follow-up. So, now, for the specific example. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I reviewed the edit of &lt;a href=&quot;https://mathoverflow.net/questions/21003/polynomial-bijection-from-mathbb-q-times-mathbb-q-to-mathbb-q&quot;&gt;Polynomial bijections from Q x Q to Q&lt;/a&gt; now improved to  &quot;Polynomial bijections from $\mathbb{Q} \times \mathbb{Q}$  to $\mathbb{Q}$&quot; (this is the full improvement!) I rejected it as 'too minor' one of the default reasons, however, it was approved by two others so it took effect. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As said, the edit consisted in changing &lt;em&gt;only in the title&lt;/em&gt;, for the rest it was not necessary as already done long ago, &quot;Q x Q to Q&quot; to &quot;$\mathbb{Q} \times \mathbb{Q}$  to $\mathbb{Q}$&quot;. In my opinion, an edit can hardly be more minor than this (also the question was old, also in the sense of not having been active very recently). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Moreover, in a recent discussion on the board now know as tea, the sentiment was expressed by some, not including me I was rather on the opposite side of the debate, that &quot;texifying&quot; is not universally appreciated, in particular not in irrelevant cases (where there is no risk of misunderstanding or decrease of readability), also mentioning loading time as concern. (I do not fully agree with this, but specifically for titles I agree, as the commulated longer loading for lists of question can be annoying.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, to cut a long story short: &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Should edits like changing &quot;Q x Q to Q&quot; to &quot;$\mathbb{Q} \times \mathbb{Q}$  to $\mathbb{Q}$&quot; &lt;em&gt;once&lt;/em&gt; when it is &lt;em&gt;clear&lt;/em&gt; the rationals are meant be made even if it bumps the question?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Perhaps let us say vote &lt;strong&gt;up&lt;/strong&gt; for: no, they should not be made, and &lt;strong&gt;down&lt;/strong&gt; for yes.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(I hope it is alright to use answers in this form and induce voting in this way; I CW it though not sure this is relevant on meta.) &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorUserId="-1" LastEditorDisplayName="user9072" LastEditDate="2017-04-13T12:58:29.980" LastActivityDate="2013-07-06T21:52:35.547" CommentCount="33" CommunityOwnedDate="2013-06-29T22:26:22.213" ContentLicense="CC BY-SA 3.0" />

By inappropriate, I mean things like calculus homework, &quot;what's wrong with this proof that 0=1&quot;, etc.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This would presumably need to be measured by an SE team member, although the MO moderators can also offer their qualitative opinion (as far as I remember from my time as a math.SE mod, there are no migration / closing statistics available to site moderators). While any current information about this would be welcome, the switch to SE 2.0 is still quite recent, so perhaps the data should be reviewed in a few weeks to get a better sense of the effect of the switch.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The questions to be counted would be those that were migrated to math.SE (though of course this has only been an option since the switch), and those that were simply closed due to inappropriateness. Now, the range of close options used on inappropriate questions was, and is, wide, and I think several of those close options from MathOverflow 1.0 do not exist anymore as a result of the switch, which increases the difficulty of automating the tabulation of inappropriate questions that were closed. One thing that may help would be to do a site-wide search for comments such as &quot;&lt;em&gt;Crossposted to math.SE [link]&lt;/em&gt;&quot; because this would correlate well to questions that were ultimately closed for being inappropriate.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I suspect the answer will be that this rate has increased.

That seems to me like a definition by non-essentials.  Some questions on math.stackexchange.com are on some fairly sophisticated topics.

I am not sure if all I say is fully correct [added: turns out it is not], but after some thought this scenario seems reasonable and  compatible with all reported and observed behavior. (I also wrote something like this on &quot;tea&quot; but thought I repost it here for visibility). My main reference is the following (official) &lt;a href=&quot;http://blog.stackoverflow.com/2010/04/openid-one-year-later/&quot;&gt;blog post on OpenID on the network&lt;/a&gt; previosuly mentioned in my comment. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In order to use a site via Google OpenID (or also other OpenID providers) the site is given an OpenID string (by the provider) to identify the user. For Google (yet not some other providers) the OpenID string does not only depend on the &lt;em&gt;gmail account&lt;/em&gt; but also on the &lt;em&gt;domainname of the site&lt;/em&gt; for which it is to be used. In particular, KConrad's OpenID string for mathoverflow.net is different from the one for stackexchange.com, and since it appears all other sites in the network used by KConrad are [something].stackexchange.com for KConrad only MO has the property of upon login not giving his OpenID string for stackexchange.com (but rather mathoverflow.net). [Added: This is wrong, since the OpenID strings for different stackexchange.com are also different, and the subsequent speculations are thus also not correct.] (A more elaborated and abstract version of this is to be found in said blog-post.) After this explanation the blog-post says:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;That’s a major bummer for site networks like us with multiple domains. We use the OpenID string as your user &quot;fingerprint&quot;, so if your &quot;fingerprint&quot; changes, we can’t tell who you are any more. It’s a frustrating problem, but we think we’ve finally come up with a fix: &lt;strong&gt;we demand email from Google GMail OpenIDs!&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;So, SE has typically two identifying pieces of information for a user (using Google OpenID). &lt;em&gt;One&lt;/em&gt; OpenID string, generated for some of their domainnames (likely the first ever used) and the associated email address (to get this they need to ask permission, which is the step discussed here). This email is then stored. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I assume KConrad's &quot;fingerprint&quot; (see the quote above) is his OpenID string&#xA;&lt;em&gt;for stackexchange.com&lt;/em&gt;. This OpenID string is likely the same over all the others sites except MO he uses, as all seem to be [something].stackexchange.com (yet not stackoverflow.com for example), so the &lt;em&gt;domainname is the same&lt;/em&gt; and Google gives out the same string. Likely, permission was granted SE &lt;em&gt;once&lt;/em&gt;, and now long ago, to retrive the email address when he started using the network. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Thus, when he logs in to one of the stackexchange.com sites the system recognizes the OpenID string Google gives (the one for SE.com) as his  &quot;fingerprint&quot; and thus has no need for the email address.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If however, he logs in to MO, then Google gives his OpenID string for MO.net, which is different. Thus, this is &lt;em&gt;not&lt;/em&gt; his &quot;fingerprint&quot; and the system does not recognize him. And, thus, needs to ask for the second piece of indentifying information the email-address. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The reason that this was a non-issue on the old MO is that there was only one domainname at all, and thus the OpenID string was always suffcient.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The reason that this does not happen to everybody using Google OpenID for MO now, is that for some (in particular those not having had an account on the network before) their &quot;fingerprint&quot; is the OpenID for MO.net. Likely, they have the dual problem, being asked on each stackexchange.com site (as reported by Scott Morrison). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Possibly a solution:&lt;/strong&gt; (This is only a rephrasing of my understanding of what Manishearth said already.) It seems to be possible to add more than one OpenID string to an account, i.e., to have more than one &quot;fingerprint&quot; recognized by the system. So, via adding the OpenID string for MO.net as additional fingerprint to the account, KConrad might be able to avoid having to grant permission each time. &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorDisplayName="user9072" LastEditDate="2013-07-04T10:22:05.730" LastActivityDate="2013-07-04T10:22:05.730" CommentCount="3" ContentLicense="CC BY-SA 3.0" />

Namely, every mathematician hopes that the questions on which they are currently working---whether for their dissertation or a later project----is an open question. These open questions come in all types, some interesting, some difficult. Let us welcome them here and give them our attention and consideration. I suspect that with the talented people we have here on MO, many of these questions will find an answer. This is a sense in which I think that nearly everyone already agrees on the matter.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;But second, in a wider sense, I think that it would actually be good for the site for us to encourage people to ask open questions of all sorts, including very prominent ones. Surely there is a continuum of open questions ranging from very easy ones up to the more normal MO questions and on up to the famous open questions. There already are some very interesting open questions on MO, such as the question on polynomial bijections from $\mathbb{Q}\times\mathbb{Q}\to\mathbb{Q}$ and many others, which I think of as highlights of the site, even though they are open. Let's build a collection of the best questions in mathematics! As answers, we can post information about resources, history, partial solutions, related problems.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I would expect that many of the more famous open questions could become some of the highest-voted questions on the site, a situation that would address the worry some have had about other softer questions currently occupying that role. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Imagine that the top-voted questions on MathOverflow were all the most popular open questions in mathematics!

In addition to voting posts up and down, you can accept answers to your own questions. To do this, just click the check mark that appears to the left of the answer you'd like to accept (this check mark will only appear if you asked the original question). This gives the person who answered your question 15 reputation points and gives you 2 reputation points. You can &quot;unaccept&quot; the answer by clicking the check mark again.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Interesting/Ignored Tags&lt;/strong&gt;.

You can tell that a post has been edited because it says something like &quot;edited 8 hours ago&quot; or &quot;edited yesterday&quot; at the bottom. If you click on &quot;8 hours ago&quot; (resp. &quot;yesterday&quot;), you can see the full edit history of the post.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;View Markdown source&lt;/strong&gt;. Suppose you're really curious how somebody typeset something in a question or answer (I think I'm not the only one this happens to). If the post has been edited, you can view the edit history (see Tip 4) and click the &quot;view source&quot; link above a revision. This will show you exactly what the person typed in order to get the result you see. If the post has not been edited, then it's a little trickier to view the edit history. First you have to find the number of the post. If the post is a question, then it has a url like &lt;a href=&quot;https://mathoverflow.net/questions/&quot;&gt;https://mathoverflow.net/questions/&lt;/a&gt;&lt;b&gt;number&lt;/b&gt;/blah-foo-bar. If the post is an answer, you can click the &quot;link&quot; link at the bottom of the answer to get a url like &lt;a href=&quot;https://mathoverflow.net/questions/123/blah-foo-bar/&quot;&gt;Linearity of the inner product using the parallelogram law&lt;/a&gt;&lt;b&gt;number&lt;/b&gt;#&lt;b&gt;number&lt;/b&gt; (the two &lt;b&gt;numbers&lt;/b&gt; will be the same). Once you know the number of the post, you can get to the edit history by going to the URL &lt;a href=&quot;https://mathoverflow.net/revisions/&quot;&gt;https://mathoverflow.net/revisions/&lt;/a&gt;&lt;b&gt;number&lt;/b&gt;/list.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Bookmark/Favorite a question&lt;/strong&gt;. Suppose you really like a question or you really want to be able to find it easily later. You can add it to your favorite questions list by clicking the little star next to the question. Click the star again to &quot;unfavorite&quot; it. To see a list of your favorite questions, go to the &quot;favorites&quot; tab on your user page.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Use problematic characters in URLs&lt;/strong&gt;. Sometimes your links will behave strangely in posts because they contain a disallowed character. For example, the text&lt;br&gt;&lt;code&gt;&lt;a href=&quot;http://en.wikipedia.org/wiki/Castelnuovo&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://en.wikipedia.org/wiki/Castelnuovo&lt;/a&gt;–Mumford_regularity&lt;/code&gt;&lt;br&gt; ends up linking to&lt;br&gt; &lt;code&gt;&lt;a href=&quot;http://en.wikipedia.org/wiki/Castelnuovo&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://en.wikipedia.org/wiki/Castelnuovo&lt;/a&gt;&lt;/code&gt;&lt;br&gt; To fix this, you have to &lt;a href=&quot;http://en.wikipedia.org/wiki/Percent-encoding&quot; rel=&quot;nofollow noreferrer&quot;&gt;percent encode&lt;/a&gt; the troublesome character. In this case, you’d type&lt;br&gt; &lt;code&gt;&lt;a href=&quot;http://en.wikipedia.org/wiki/Castelnuovo%E2%80%93Mumford_regularity&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://en.wikipedia.org/wiki/Castelnuovo%E2%80%93Mumford_regularity&lt;/a&gt;&lt;/code&gt;&lt;br&gt; to get a good link.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;All characters outside ISO Latin 1 are disallowed, and need to be encoded using their &lt;a href=&quot;http://en.wikipedia.org/wiki/UTF-8&quot; rel=&quot;nofollow noreferrer&quot;&gt;UTF-8&lt;/a&gt; byte sequence (e.g., the en-dash character above, U+2013, is represented as E2 80 93 in UTF-8, hence it is percent-encoded as %E2%80%93). Furthermore, some ASCII characters require percent encoding, because they conflict with Markdown syntax, or because they are URL reserved characters. This list may be non-exhaustive:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;code&gt;*&lt;/code&gt;&#xA;  &amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;code&gt;$&lt;/code&gt;&#xA;  &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;code&gt;[&lt;/code&gt;&#xA;  &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;code&gt;]&lt;/code&gt;&#xA;  &amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;code&gt;(&lt;/code&gt;&#xA;  &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;code&gt;)&lt;/code&gt;&#xA;  &amp;nbsp;&amp;nbsp;(space)&lt;br&gt;&#xA;  &lt;code&gt;%2A&lt;/code&gt;&#xA;  &lt;code&gt;%24&lt;/code&gt;&#xA;  &lt;code&gt;%5B&lt;/code&gt;&#xA;  &lt;code&gt;%5D&lt;/code&gt;&#xA;  &lt;code&gt;%28&lt;/code&gt;&#xA;  &lt;code&gt;%29&lt;/code&gt;&#xA;  &lt;code&gt;%20&lt;/code&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Other reserved characters may appear in a URL, but they have a special function: e.g., &lt;a href=&quot;http://en.wikipedia.org/w/index.php?title=Algebraic_variety&amp;amp;action=history&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://en.wikipedia.org/w/index.php?title=Algebraic_variety&amp;amp;action=history&lt;/a&gt;. They need to be percent-encoded when this special function is not intended: &lt;a href=&quot;http://en.wikipedia.org/wiki/AT%26T&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://en.wikipedia.org/wiki/AT%26T&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Many browsers automatically percent-encode non-ASCII characters and reserved characters (but not Markdown special characters) as necessary in URLs copied from the address bar, sparing you the trouble of manual encoding.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Follow up on your recent comments&lt;/strong&gt;. It's easy to follow up when somebody replies to one of your posts (see tip #1), but you might find yourself saying, &quot;I left a comment that I really meant to check up on later, but I can't remember where I left it.&quot; In that case, try clicking the &quot;recent&quot; tab on your user page. It will show you a list of all the comments you left in reverse chronological order, along with links to the posts on which you left them. It also shows you when you asked, answered, edited, or accepted an answer.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;RSS feeds&lt;/strong&gt;. MathOverflow has feeds for recent questions, questions within a given tag, activity on a single question, activity of a given user, and probably some others I don't know about. To find the link for the feed, just scroll down to the bottom of the page and click the  (e.g. to get the feed for a given user's activity, scroll to the bottom of that users profile page; to get the feed for recent questions, scroll down to the bottom of the home page).&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;What do the colors mean?&lt;/strong&gt; The color of the &quot;number of answers&quot; box and the background color of an answer tells you the following things:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Votes box, Answer background, Question background&#xA;  unanswered, answered, accepted, accepted, deleted, has interesting tag, has ignored tag&lt;/p&gt;&#xA;&lt;/blockquote&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Escape Markdown special characters&lt;/strong&gt;. Characters like * and _ have special meaning in Markdown (the markup language used by the WMD editor). You can escape them with a backslash. For example, write &lt;code&gt;\&lt;em&gt;test\&lt;/em&gt;&lt;/code&gt; to get &quot;*test*&quot; rather than &quot;&lt;em&gt;test&lt;/em&gt;&quot;. You can also escape these characters in comments.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Use boolean operators on tags.&lt;/strong&gt; You probably already noticed that you can see all questions with a given tag by clicking on the tag, and maybe even that you can combine tags to see questions that use both (by clicking on the &quot;related tags&quot;), but you can also search for questions that use one tag OR another or search for questions that use one tag, but NOT another. For example, the URL&lt;br&gt;&#xA;&lt;a href=&quot;https://mathoverflow.net/questions/tagged/homological-algebra%20or%20representation-theory%20-algebraic-geometry&quot;&gt;&lt;a href=&quot;https://mathoverflow.net/tagged/homological-algebra&quot;&gt;https://mathoverflow.net/tagged/homological-algebra&lt;/a&gt; or representation-theory -algebraic-geometry&lt;/a&gt;&lt;br&gt;&#xA;will show you a list of questions that are tagged ([homological-algebra] OR ([representation-theory] but NOT [algebraic-geometry])).&#xA;NOT (denoted by by prefixing a &quot;-&quot;) binds tighter than AND (denoted by a space) binds tighter than OR (denoted by the word &quot;or&quot;). See &lt;a href=&quot;http://blog.stackoverflow.com/2008/10/tags-and-tags-or-tags/&quot;&gt;this blog.SO post&lt;/a&gt; for more.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Wildcards in tags.&lt;/strong&gt; You can use ~ as a wildcard when searching tags. For example, to find all questions that have a tag ending in &quot;geometry&quot;, go to&lt;br&gt;&#xA;&lt;a href=&quot;https://mathoverflow.net/questions/tagged/~geometry&quot;&gt;&lt;a href=&quot;https://mathoverflow.net/tagged/~geometry&quot;&gt;https://mathoverflow.net/tagged/~geometry&lt;/a&gt;&lt;/a&gt;&lt;br&gt;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Restrict to certain tags in searches.&lt;/strong&gt; When you use the search box, anything between brackets is interpreted as a tag, so the search &quot;&lt;a href=&quot;https://mathoverflow.net/search?q=[ac.commutative-algebra]+decomposition&quot;&gt;[ac.commutative-algebra] decomposition&lt;/a&gt;&quot; searches &lt;em&gt;within&lt;/em&gt; the [ac.commutative-algebra] tag for questions containing the word &quot;decomposition&quot;.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;See original math input.&lt;/strong&gt; Sometimes you want to see the original input corresponding to some MathJax output. You can see it by right clicking on the MathJax output.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Search MathOverflow like a ninja.&lt;/strong&gt; Let's face it: MathOverflow's search functionality is sometimes not so hot, but you can take advantage of the fact that MathOverflow is heavily indexed by Google. If you want to search comments or search for a phrase, you can use a google search like &lt;a href=&quot;http://www.google.com/#q=site:http%3A%2F%2Fmathoverflow.net+%22wicked+smooth%22&quot; rel=&quot;nofollow noreferrer&quot;&gt;site:&lt;a href=&quot;http://mathoverflow.net&quot;&gt;http://mathoverflow.net&lt;/a&gt; &quot;wicked smooth&quot;&lt;/a&gt; or &lt;a href=&quot;http://www.google.com/#q=site:http%3A%2F%2Fmathoverflow.net+%22can%27t+argue+with+that%22&quot; rel=&quot;nofollow noreferrer&quot;&gt;site:&lt;a href=&quot;http://mathoverflow.net&quot;&gt;http://mathoverflow.net&lt;/a&gt; &quot;can't argue with that&quot;&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;This trick can also be used to search user pages. For example, if you want to find MathOverflow users whose profile contains the phrase &quot;finite groups&quot;, try &lt;a href=&quot;http://www.google.com/search?q=site%3Amathoverflow.net%2Fusers%2F+%22finite+groups%22&quot; rel=&quot;nofollow noreferrer&quot;&gt;site:mathoverflow.net/users/ &quot;finite groups&quot;&lt;/a&gt;.

There is simply a big difference between making a post that is on some paper, and a post happening to link to a paper. (This remains true if this is restricted to links in questions.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;This also applies to the arXiv trackback in a certain way. But first there are many many papers on the arXiv while there are not yet that many posts on this site, so it is in a relative sense not so much problem, besides these trachbacks on the arXiv being quite a side-aspect while on this site they are the main thing. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, if we send them many low-quality entries (at least for the purpose at hand) this is seems like a problem.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(Final explication what I mean with &quot;problematic&quot;: sometimes certain (not all) discussions of preprints here on MO are critizised as potentially offensive or embarassing for the author, &lt;em&gt;still&lt;/em&gt; a track-back is created, as it is automatic, so that everybody looking at the arXiv might stumble over this potentially offensive discussion. This is a slightly strange state of affairs in my opinion. But then these trackbacks are not so visible, but for that other site this is a bit different. In addition, it could also make sense to inform people that what they say here on MO on a paper, will in some immediate way be linked to the paper. It is not clear to me if everybody is aware of this.

But encouraging an author to improve their work doesn't necessarily imply it can (or even &lt;em&gt;should&lt;/em&gt;) be salvaged. At the very least, the introspection might help them improve their work in the future. That's the point of the new close system. It gives users clearer guidance about where they went wrong so they can either (a) fix the problems or, failing that (b) not repeat them in the future. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Certainly some questions are destined to (and &lt;em&gt;need&lt;/em&gt; to) be closed, no doubt. But having the core software tell you that your question is not real by default has fueled the growing belief that we are more interested in alienating users who haven't learned all our nuances of how to ask, rather than helping them with their problem.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;You don't get it so this needs to be closed. Buh-bye.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;At least that's the perception. It's this &lt;em&gt;&quot;no one is interested in helping me&quot;&lt;/em&gt; ethos that the new close system is designed to address:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;http://blog.stackoverflow.com/2013/06/the-war-of-the-closes/&quot;&gt;&lt;strong&gt;War of the Closes&lt;/strong&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There's nothing about the new close system asking you change what questions you accept, or how to moderate users who are unlikely to contribute to this site. But the truth is, our original close system was designed with the &lt;em&gt;experienced&lt;/em&gt; community in mind&amp;hellip; while neglecting to help the &lt;strong&gt;&lt;em&gt;author&lt;/em&gt;&lt;/strong&gt; of the question understand what the heck was going on. The default messaging built into the old system &amp;mdash; how potentially brilliant new users were treated by default &amp;mdash; did little to help hapless new users understand the system of improving their content so it &lt;em&gt;could&lt;/em&gt; work.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In contrast, the new close system was written with the the author (and majority of less-experienced users looking on) in mind &amp;mdash; part peer review, part educational.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;This question is not usable because of the following problems.

There are instances where no followup is going to save that post.

This is just an update.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Unfortunately, code I'd written previously that interacted with the Stack Exchange API used API v1.1. They've since upgraded to v2.1 of the API, and v1.1 won't be available for MathOverflow. This reduces my personal enthusiasm for writing this code (because it's more work than I'd expected), but shouldn't be an obstacle for anyone else.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Here's the basic idea for a program that generates trackbacks.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;There are two essentially independent programs, that need to be run on a recurring basis (at least daily, maybe as often as hourly). They interact only via an append-only text file (or something equivalent). Each has a tiny amount of 'internal state' that needs to be preserved between runs of the program, namely the time at which the program was last run.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Program 1 is the &quot;scraper&quot;&lt;/strong&gt;, responsible for finding new MathOverflow content that contains arXiv links. It should request, via the SE API, all new content (i.e. new posts, new comments, as well as edited posts) between the last run of the scraper and the current time. For each such piece of content, it should run a certain set of regex's (there are important details here; we should reuse the existing well-tested set) on the content. These regex's will output any arXiv ids found in the content (possibly several). For each id found, the scraper should append to its log 4 pieces of data:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;the current time&lt;/li&gt;&#xA;&lt;li&gt;the arXiv id&lt;/li&gt;&#xA;&lt;li&gt;the URL of the content (it doesn't really matter if this is the URL of the question or a more specific URL)&lt;/li&gt;&#xA;&lt;li&gt;the title of parent question&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Program 2 is the &quot;poster&quot;&lt;/strong&gt;, responsible for sending trackbacks. On each run, it should inspect the output log from the scraper, and take all entries since the last run of the poster. For each entry, it should perform a GET request to the arXiv, according to this example:&lt;/p&gt;&#xA;&#xA;&lt;pre&gt;&#xA;http://arxiv.org/trackback/1307.1702?blog_name=MathOverflow&amp;title=A%20Question&amp;url=http://mathoverflow.net/questions/123&#xA;&lt;/pre&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;That's pretty much it!&lt;/p&gt;&#xA;&#xA;&lt;p&gt;A few comments:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;The &quot;poster&quot; program will eventually gain extra duties; for example the &lt;a href=&quot;https://selectedpapers.net/&quot; rel=&quot;nofollow&quot;&gt;selected papers network&lt;/a&gt; would like us to notify them too.&lt;/li&gt;&#xA;&lt;li&gt;We need to notify the arXiv administrators of the IP address of the machine doing the posting, so they can whitelist submissions.&lt;/li&gt;&#xA;&lt;li&gt;It would be nice to be able to &quot;re-run&quot; the scraper over old content, without generating duplicate trackbacks, in case we miss something, update regex's, etc. This might be as simple as resetting the 'last run' timestamp, then deduplicating the log file.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;" OwnerUserId="3" LastActivityDate="2013-07-09T03:19:43.527" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

While I am no judge for the actual &lt;em&gt;content&lt;/em&gt; on &lt;a href=&quot;http://cstheory.stackexchange.com&quot;&gt;TCS&lt;/a&gt;, based on traffic statistics alone it is doing quite alright as a graduated site on the SE network. So this will not be an instance like when the lights were turned off on Theoretical Physics. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So... &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The status quo is not a bad one.&lt;/li&gt;&#xA;&lt;li&gt;MathOverflow will not change much even if we &quot;merge&quot; with TCS (based on traffic statistics the change to MathOverflow will not be so noticeable). &lt;/li&gt;&#xA;&lt;li&gt;MathOverflow has never out-right rejected questions on theoretical computer science.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;... there really isn't a reason for us to strongly prefer one or the other.

If you want to discuss cstheory you should post on its meta not in other places. Moreover, you are not an active user on either of these sites so I am not sure you are qualified to express opinion on the issue. It is better to leave these issues to people who are actively using these sites.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Second, remember that an SE site is not defined by its topic but by its target community. We have argued about this kind of issues several times with people who are not active participants (e.g. shouldn't we merge MSE and MO?) and I should say I really don't understand why these people who are not actively participating on these sites feel confident and knowledgeable enough to make such major suggestions. It is amazing that almost always these suggestions come from people who are not active on these sites which is kind of annoying, even more so when they know that they shouldn't (as you did).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now, these said, as a user (not a moderator on cstheory) I think there is a considerable overlap between MO and cstheory, and many theoretical computer scientists definitely feel that they are also mathematicians. But many theoretical computer scientists also definitely feel that they are computer scientists.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There is a considerable number of questions on cstheory that might not be very welcome on MO. Note that we interpret TCS in a broad sense:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;TCS covers a wide variety of topics including algorithms, data structures, computational complexity, parallel and distributed computation, probabilistic computation, quantum computation, automata theory, information theory, cryptography, program semantics and verification, machine learning, computational biology, computational economics, computational geometry, and computational number theory and algebra. Work in this field is often distinguished by its emphasis on mathematical technique and rigor.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I personally don't have a strong opinion either way right now, I haven't thought about cons and pros. I also don't know how cstheory community would feel about this. It might be the case that cstheory community would be fine with a merge, so far we haven't felt a need to discuss it and right now I don't see why we need to discuss it other than to make the world fit into someone's mental picture who is not an active user on either site. If a user who is actively using cstheory suggests it and explains why a merge with MO can be beneficial for the cstheory community then we can discuss its cons and pros (on cstheory).

In fact this &lt;a href=&quot;https://meta.stackexchange.com/questions/183109/the-association-bonus-should-not-enable-users-to-vote-on-every-site&quot;&gt;request exists on meta.SO&lt;/a&gt; presented by Mad Scientist about a month ago. It could also make sense that those that care about it, voice there opinion there too, or at least vote on it. (I did not yet myself, but I think it is as simple as just login in as on MO and then one can vote due to the association bonus, somewhat ironic, though not quite as the meta.SO is a special case for a site.)&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;For some other things I now think it is somewhat reasonable. I did not yet say anything on math.SE but created an account recently, the actual motivation was to test something as a low-rep user somewhere, but also I could imagine to say want to say something on a question after it was migrated there, and then it would feel odd if I could not comment there, so there is some sense to this association thing, too.

Since for somebody to get something out of having sock-puppets here to vote the need at least to be in some sense in touch with the subject of the site.

And then we had also some that had some &quot;colleague&quot; ask a question that they then answered, so I would say it was always easy enough. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;However, I still agree that for voting in general it is a bit of a problem, as it likely will still give more votes to the soft-ish things that already get too many votes, IMO.

And, it might be that on MO this is in general less relevant, since it is not so common that there are very similar answers given to the same thing, however it can also happen. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In particular in such situations there is an effect that not rarely one of the answers &quot;wins&quot; in the end and gets significantly more votes than equivalent ones (on the grounds that it is ahead early on, and then some seem to only upvote one/the first they see (often sorted by votes), answer giving some piece of information and the gap widens.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, I think in a scenario where one answers in parallel with somebody else about the same thing, then sees the other answer, and then upvotes it. Then by doing so one likely actually harms ones prospects of getting points out of ones own answer (and also the accept). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;This is I think the scenario they mainly had in mind. As said on MO this is not so frequent but I think on other sites it happens all the time. (And such situations can cause friction; math.SE seems to have had various problems arising from such things.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And depending on how this badge is implemented precisely; if it is exactly as written, that is the number of answers one upvotes counts (and there is no exception for CW) then anybody being in some of big-lists could trivially get it just voting around there a lot.   &lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, that one can also get the badge in an &quot;absurd&quot; way is true for many and specifically for thos badges based on participation/volume.

Other entities, in whose hands this decision was, where a) the moderatots b) the system (by which I mean auto-CWing one edits or number of answers). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And this was not at all only theoretical. There were cases of questions that were made CW by moderators &lt;em&gt;against&lt;/em&gt; the explicitly expressed wish of the author (to be clear I fully support these decisions). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;For b) this also happened, at least upon edits (I think for the answer threshold it was mostly done before manually), mostly by accident, in an irreversible ways. (This persists but now can be reversed, which one also can see as improvement, although to be fair one could keep this improvement and still go back to the old way regarding other aspects.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now, depending on how you read the above you might think this is nit-picking, however, what this also shows is that in my opinion and this is the point I want to make here: &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The decisions if a specific question is to be CW or not was all the time much more a &lt;em&gt;matter of following guidelines&lt;/em&gt; [edit: replaced a word] regarding the type of questions that should be CW than an actual decision of the author. Some authors that knew about the guidelines merely did it right away. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Second, regarding the &quot;nothing to fear.&quot; Well, I am not so easy to scare, at least not by questions on MO, so no we have nothing to fear. But then since also the comparison to other sites is made where this might be an issue but here on MO it is not. I really recommend the blog-post I link below. The type of problems (if one sees them as problems, as some though not all do) on other sites described there are &lt;em&gt;precisely&lt;/em&gt; analogous to what we have on MO, too. (As a general aside, while I agree MO is in some ways special, I think we should also avoid to overdo pointing this out, because then in various ways it seems to me the problems &lt;em&gt;are&lt;/em&gt; in fact quite similar, and the situations are not that different.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Third, for the specific qustions mentioned as example. It is even not so clear in my opinion that this must be CW for intrinsic reasons, and a slight modification (sharpening/improving the questions slightly) could make it in my opinion easily a non-CW question. (Again, I refer to the blog-post.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This example to me seems precisely like one where CW is &quot;abused&quot; (this is not directed against the author, it is a common use here after all). My reading of CW-ing here is, [added: this is as indicated by the 'my reading' my personal interpretation, and could be wrong, but there were examples where things like what I say below were made explicty by an author or by others in discussion] that the author was well aware there could be opposition to such a question (whether this is good or not is not the question), and it has three votes to close at the time of writing, yet via entering the CW grey-area thought to avoid some of it, and sufficiently much of it that the question &quot;survives.&quot; This is precisely how CW should &lt;em&gt;not&lt;/em&gt; be used (that it was done a lot in the past does no change this).          &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Added: since apparently there is a considerable interest in my arguments (with 5 upvotes on the comment demanding them while half-way they are in comments already) here is one reason why I prefer the new systme over the old one and also the proposed one (somewhat redundant with comments): &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A main point why I prefer the new system is that it should minimize certain small debates in comments that I do not find very productive. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The question of whether a question is CW or not is ultimately pretty much to the irrelevant end, in my opinion. In particular, this is not a very urgent matter. I agree some questions rather should be CW, but if they are not for a while early on it also does not change much. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;But, for some reason some people seem to have relatively strong feelings about this (to avoid confusion, I do not mean Todd Trimble). Also, some, and sometimes the same approach this CW matter in ways I find strange. Berating users where it is really reasonable they did not know about it, or even worse could not even make it CW by themselves, some even voting to close over such things, which is one of the more inapproriate reasons for a vote to close in my opinion. Leaving comments  like: &quot;this is a community wiki question, voting to close until it is so labeled&quot; (the until is an additional strange detail, but anyway).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Or, and this annoys me really a lot out of principle: &lt;em&gt;ask&lt;/em&gt; OP to make it CW and at the same time &lt;em&gt;answer&lt;/em&gt; the question in non-CW.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is a mystery to me how one can justify to do this. It is particularly annoying (but some seem unaware of this aspect) since then even if OP reacts in a timely manner moderator intervention is needed as the answers stay nonCW and CW is mainly so that the answers are in CW so a quite absurd situation arises. But even if I would not know this I cannot understand how one can ask for it to be CW and not oneself set the accompanying example. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, in my opinion, each such event reflects negatively on the site. With the new system this is a lot more unlikely to happen in this form. This is an improvement. &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;The main reason for it is  AFAIK  is to discourage the type of questions that got asked in CW. See this blog post &lt;a href=&quot;http://blog.stackoverflow.com/2011/08/the-future-of-community-wiki/&quot;&gt;http://blog.stackoverflow.com/2011/08/the-future-of-community-wiki/&lt;/a&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;There were debates surrounding this, so it is somewhat unlikely this will be changed (in the sense that others raised the same point with similar arguments we might make).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;To your specific suggestion, I would be &lt;em&gt;against&lt;/em&gt; introducing a rep limit, since this will only create confusion.

And, second, to potentially discuss the implications of  and potential solutions for this. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;To be more specific what I am talking about, a main usecase:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There is a lower bound on the length of characters a comment needs to have, sometimes one might wish to post a shorter comment and then a way in which some proceed  is to add some MathJax code, like &lt;code&gt;${}{}{}{}{}$&lt;/code&gt; that after having been processed does not display anything (under normal circumstances).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are also some related things like, displayed equations to have a paragraph in a comment and so on. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What is the problem or the inconvenience?&lt;/strong&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The problem is that some (or at least I) also view the site on devices where MathJax either does not process properly at all or very slowly. Then, this 'invisible'  formatting code is visible, and distracting, and it is not only distracting in the way some normally visible 'filler text' would be distracting, as for example it can happen that first it grays-out (slightly changing size) to then reappear as normal text. So that automatically attention gets focused on this 'movement' against the static background. Or, it simply contributes to slow down the site, impeding smooth scrolling and so on. Also, the paragraph in comments can 'suddenly' open-up while reading the comment when the MathJax is eventually processed. (Besides it being quite a bit too large for a paragraph, which can be inconvenient on devices with a small screen.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Since this was already misunderstood, let me stress that my problem is not with the fact that some post short comments. I do not mind this at all, and would not mind were there no character limits (actually I would strongly prefer it as then the issue discussed here would disappear).  I only mind that this is done using MathJax. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Bottom line:&lt;/strong&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Personally, I can see why &lt;em&gt;sometimes&lt;/em&gt; it is actually convenient to have such tricks available, but it is also my impression that it is frequently used just so, since people know how to do it, so they do it (some likely unaware of negative side effects), and I assumed that at least for some in some cases it would not make much difference to reply, say, 'Yes, this is possible.' instead of 'Yes. [plus some 'invisible' filler]' &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, it is my hope that some might take the above mentioned problems into account when deciding whether to use such tricks or not. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And, possibly, somebody could make a good suggestion for other ways to achieve the same without the negative side aspects. Indeed, there appear to be also ways to do 'invisible' things differently, there are invisible characters that can be 'written' in various ways; personally, I do not yet know how to do this (there is various talk about this on meta.SO but I did not get it to work, which might be my ignorance or that these workarounds meanwhile have been blocked) see &lt;a href=&quot;https://meta.stackexchange.com/questions/44011/zero-width-non-joiner-allows-unclickable-titles/&quot;&gt;Zero-width non-joiner allows unclickable titles&lt;/a&gt; for example.   &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorUserId="8250" LastEditDate="2020-05-08T05:28:06.823" LastActivityDate="2020-05-08T05:28:06.823" Title="On using MathJax to create 'white space'" Tags="|discussion|mathjax|etiquette|" AnswerCount="4" CommentCount="24" ContentLicense="CC BY-SA 4.0" />

My aim was to interpolate somewhat beteween the two points of view given in the two answers, yet giving somewhat more weight to the one that had more support.&lt;/p&gt;&#xA;&lt;p&gt;The intent was also to stress more what can be asked or done than what cannot, not only but also as it should be rather on the 'what can is ask' page than on the 'don't ask' one. Not sure how well I suceeded though.&lt;/p&gt;&#xA;&lt;p&gt;I welcome feedback of all kind. Both regarding content, form, and details like the language (the goal is this will make it into the official documentation in one form or another so thus seems relevant). In particular, for the latter feel free to edit directly. (Also, for the former if you find it more convenient, but perhaps please leave a comment what you changed, so that it is a bit clearer than just from the revision history who thinks what).&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;To ask questions related to a (well-known) open problem, that is a problem of which you know that  it (yet not its solution)  is known at least to the experts in the relevant field, can be welcome. However, there are some things to consider, which are mainly consequence of general principles making a good question or a good problem a good fit for this site.&lt;/p&gt;&#xA;&lt;p&gt;If you know that something is a (well-known) open problem, please, indicate this clearly in the question itself and provide some information or pointers to information on the context and status of the problem. In addition, please, use the open-problem tag (in addition to mathematical tags to indicate the subject). Otherwise, the unfortunate situation can arise that the only reply you get is something along the lines: 'This is a well-known open problem, see the following references.' This could be a valuable answer for you, had you not known it already, but since you know it already, it is likely not what you hoped for. Conversely, it can be frustrating for the person answering to spend time to provide you with information of which it then turns out you had already. Thus, please provide context.&lt;/p&gt;&#xA;&lt;p&gt;This site is a question and answer site. Thus, the typical question should be of a form where you consider it as &lt;em&gt;reasonably likely&lt;/em&gt; that it is &lt;em&gt;answerable by somebody&lt;/em&gt; (at the time the question is asked). Therefore, this site is typically not a good fit for asking for solutions of a problem open since some time and known to most people most likely to answer it. Thus, if you know an open problem you consider as particularly interesting and you feel it is not sufficiently present in the literature or on the internet you might consider to contribute it on a site that collects open problems in mathematics such as the &lt;a href=&quot;http://www.openproblemgarden.org/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Open Problem Garden&lt;/a&gt; instead of asking it here. Or, you ask a &lt;em&gt;related question that seems more answerable&lt;/em&gt;, such as a question on the current progress towards the problem, a question on  known results in special cases, etc. (of course, always assuming that this information is both of interest to you and not readily accessible elsewhere; following the two general principles that you should try to ask only questions whose potential answers are of actual interest and value to you, and that you should try to look-up other sources of information before asking a question here).&lt;/p&gt;&#xA;&lt;p&gt;A situation where you come across a problem that you, and possibly some colleagues around you, cannot answer but of which it is not known to you that it is also known to many others already is &lt;em&gt;not what is meant by open problem&lt;/em&gt; here. A question on it is typically very welcome, provided it is presented in context and it is within the scope of the site (research-level mathematics) from a general point of you.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Added:&lt;/strong&gt; the intent is to replace this text:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;What about open problems?&lt;/p&gt;&#xA;&lt;p&gt;MathOverflow is not the right place to ask open problems. You should post questions you're actually seriously thinking about. If you're thinking about a well-known open problem, provide some background and ask about something specific related to the problem, like &amp;quot;Such and such is a well-known open problem. So-and-so proposed this and that approach in the 80s. Does anybody know if this aspect of their proposal can be made to work under these circumstances?&amp;quot; If you want to contribute to (or view) a list of open problems, visit the Open Problem Garden.&lt;/p&gt;&#xA;&lt;p&gt;If it turns out that a problem is equivalent to a known open problem, then the [open-problem] tag is added, and the question is converted to community wiki. After that, the question essentially becomes, &amp;quot;What is known about this problem? What are some possible ways to approach this problem? What are some ways that people have tried to attack it before, and with what results?&amp;quot; That way, the MO thread for the problem becomes a repository of resources related to the problem. Perhaps the answers could be organized by approach, with an outline of the basic approach, followed by a horizontal rule and a summary of what is promising about the approach and why it doesn't give a complete solution.&lt;/p&gt;&#xA;&lt;p&gt;To join the discussion about how MathOverflow should deal with open problems, go to this meta.MO thread.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;This is what the faqs said all the time (or at least since a very long time), and what also now is &lt;em&gt;a part of&lt;/em&gt; &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;https://mathoverflow.net/help/on-topic&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;In particular, this text is not a &lt;em&gt;my  opinion&lt;/em&gt; on how open problems should be handled but by contrast &lt;em&gt;my attempt to write down&lt;/em&gt; how they are/will handled in accordance with the opinions expressed in other answers as well as in continuity with existing practise (as I see it), and also removing mention of procedures related to open problems until now mentioned in the faqs that did IIRC hardly ever happen like this in the recent and not so recent past (for example, I recall numerous questions where it turned out this is a well known open problem, but never was there any CW-ing or any attempt of creating anything like a resource).&lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorUserId="-1" LastEditorDisplayName="user9072" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2013-07-20T21:16:04.230" CommentCount="10" CommunityOwnedDate="2013-07-20T21:16:04.230" ContentLicense="CC BY-SA 3.0" />

In particular, if there are (or at least one suspects) multiple different answers possible. An example could be a list-type question where I would consider it as perfectly alright for OP of question to also contribute their own answer(s). (One might do so also in the question, but it can be clearer to maintain a clear distinction between question and answers.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Or, if somebody where, say, interested in diffeent ways of proving the same result (while knowing one or some), to hava quetion 'In which ways can one prove this' and also answer 'This is &lt;em&gt;one&lt;/em&gt; way.' would seem fine to me, as for most relevant matters it would be the same as 'Q: this is a way to prove this are there others?' no answer.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Also, the example that is mentioned in the blog-post was such that &lt;em&gt;other&lt;/em&gt; answers than the one by asker where still possible (and it was sort of likely this was so).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Mainly, I would see an issue with question-answer packages of one person that are more or less finalized from the start on, without much reasonable possibility or even interest from OP of having others' contributions in addition. &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;To avoid confusion: Of course the situation for learning the answer &lt;em&gt;after&lt;/em&gt; having asked the question is completely different and here one certainly &lt;em&gt;should&lt;/em&gt; provide the answer, or make clear in another way that one no longer has a need for an answer (say via flagging for closure) but the former seem preferable.

Share your research.&lt;/p&gt;&#xA;&lt;p&gt;If your question is about this website, ask it on meta instead.&lt;/p&gt;&#xA;&lt;p&gt;visit the help center »&lt;/p&gt;&#xA;&lt;p&gt;asking help »&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Where there are links (I did not reproduce) to the help center, to how to ask, and to meta.&lt;/p&gt;&#xA;&lt;p&gt;Now, if this is possible, I would find it a very good idea to add a sentence on and link to math.SE in this box. (Possibly not exactly the one suggested but something along these lines, for example, since some seem to be worried to tell people to ask on math.SE we could provide it more as information.)&lt;/p&gt;&#xA;&lt;p&gt;Say like adding (but this is rough just to get the idea across):&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Is your question about research level mathematics?&lt;/p&gt;&#xA;&lt;p&gt;If not, note that questions about mathematics at any level are welcome at math.SE&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;What I do not know is if this is technically possible (in an easy way). Since again this box seems to be fixed in form the only thing being specific to MO being the &amp;quot;research level mathematics&amp;quot;, which is the &amp;quot;on-topic&amp;quot; of MO (and also appears elsewhere on the site).

However, my attempt was thwarted by the system's insistence that I need five total score (i.e. total upvotes minus downvotes) in the tag 'dg-algebras' to suggest the synonym, and I do not have it.&lt;/p&gt;&#xA;&lt;p&gt;My feeling is that a lot of, if not most, synonyms are needed in fairly small tags where &lt;em&gt;very few&lt;/em&gt; people actually have any votes (e.g. 'dg-algebras'). So the five score limit for suggesting synonyms appears rather counter-productive, especially since most people who do have the required score are unlikely to be working on suggesting synonyms at least for now. Moreover, only users with more than 2500 reputation can suggest vote for synonyms.&lt;/p&gt;&#xA;&lt;p&gt;In conclusion, I have a few questions.&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Preliminary question 1:&lt;/strong&gt; How much, and what kind of discussion is required before creating a tag synonym?

I am personally not convinced at this time.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Procedural question:&lt;/strong&gt; Should I instead always make a request at meta.mathoverflow (for example, in the thread &lt;a href=&quot;https://meta.mathoverflow.net/questions/194/help-improve-tagging&quot;&gt;Help improve tagging!&lt;/a&gt;) when I want to add a synonym like the above? This procedure would appear to forego some (most?) possible benefits of allowing users to suggest synonyms. On the other hand, it would impose a minimum level of discussion before creating a tag synonym.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Main question (or feature request):&lt;/strong&gt; Can we simply remove the requirement of a total score of 5 in the tag for suggesting synonyms? Should we? We could &lt;em&gt;maybe&lt;/em&gt; even keep that requirement (as it is now) for users to &lt;em&gt;vote&lt;/em&gt; on the suggested synonyms.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;h3&gt;Some relevant meta.stackoverflow threads&lt;/h3&gt;&#xA;&lt;p&gt;Here is the most immediately relevant meta.stackoverflow thread,&#xA;&lt;a href=&quot;https://meta.stackexchange.com/questions/161971/remove-tag-score-requirement-for-suggesting-synonyms&quot;&gt;Remove tag score requirement for suggesting synonyms&lt;/a&gt;, which makes a similar request to the one I am making.&lt;/p&gt;&#xA;&lt;p&gt;Also, here is a thread describing some of the relevant inadequacies of the tag synonym system: &lt;a href=&quot;https://meta.stackexchange.com/questions/175790/remove-the-tag-synonym-suggestions-entirely&quot;&gt;Remove the tag synonym suggestions entirely&lt;/a&gt;.

This principle also applies to questions about open problems. For example, the community will usually welcome inquiries on partial progress, results in special cases, etc.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What if my question turns out to be a well-known open problem?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you ask a question which is widely known to be unsolved, someone will typically point that out and provide references to the relevant literature.

Just what is typed in the end is relevant, it is only an input-help (also see at the end).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;That there is a fontchange is relevant as if there are still more than one match then there is more then one window and you can use 'tab' repeatedly to select one of them (the one selected is bold). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you continue it dissapears as there is no more match &lt;code&gt;@Joel,&lt;/code&gt; does not match part of your username but works as the interpunctuation is ignored, &lt;code&gt;@Joel&lt;/code&gt; (with space) there is also no more window as you are ouside the scope of the @ after a space and so there is no reason to suggest anything anymore, but with &lt;code&gt;@JoelD&lt;/code&gt; the window would still be there. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Also note that some people can sometimes be notified that do &lt;em&gt;not&lt;/em&gt; get suggested, namely users that edited the post and &lt;em&gt;moderators&lt;/em&gt; that closed a question.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Additional remark: in principle, the @ is crucial but as it always was the case a comment on a post notifies owner of a post. So here you do not need it. And also if there is a unique user that could be notified, say I had commented on you question and you replied in a comment with no others present, then I also get automatically notified even if you do not use an @ (whether you use my displayname or not). In such a situation it can happen that a staring @name is autodelete upon submission of the comment. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Second additional remark: no comments on answer do not automatically notify OP of question, you cannot even notify them via comments on the answer (except of course if they also commented there).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I hope this helps a bit, though I fear my reply is not very structured.&lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorUserId="-1" LastEditDate="2017-03-20T10:31:57.100" LastActivityDate="2013-07-25T02:16:18.210" CommentCount="5" ContentLicense="CC BY-SA 3.0" />

It is thus not clear to me why this should be any different for MO. Do (m)any of the sites that have their own URL also have one under SE.com, if not why should MO have one? And, even if others did, one might be against this for MO. The reason being that it is better to keep more indpedent identity.

The advantage is it essentiall maintains itself. (This goes both for old and new meta.) &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;On main.&lt;/strong&gt; This was tried once or twice, there is however some opposition against this as it is somehow off-topic and with the new meta, most arguments (tex, less discursive,...) in favor of having it on main over meta seem obsolete.  &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;On the blog attached to the site.&lt;/strong&gt; MO could have a blog hosted by SE (like some sites have) and there this could be &quot;reported&quot; possibly also other things. This might be an alright option if someone or a couple of people volunteer to do this.

Since MathOverflow exists as an entity it might be reasonable (even independent of this) that it has its own webpage; of course the main (only?) activity of MO &lt;em&gt;is&lt;/em&gt; a webpage, still there might be some things to present or to say, which do not fit completely on mathoverflow.net (how is mO organized, its history, its successes and everything else that comes to mind).

The familiar chess pieces move about according to their usual chess rules, and each player strives to place the opposing king into checkmate. The mate-in-n problem of infinite chess is the problem of determining whether a designated player can force a win from a given finite position in at most n moves. The main theorem of this article, confirming a conjecture of the second author and C. D. A. Evans, establishes that the mate-in-n problem of infinite chess is computably decidable, uniformly in the position and in n. The proof proceeds by showing that the mate-in-n problem is expressible in what we call the first-order structure of chess, which we prove (in the relevant fragment) is an automatic structure, whose theory is therefore decidable. An alternative argument proceeds via Presburger arithmetic, which is capable of interpreting the mate-in-n problem of infinite chess.&lt;/p&gt;&#xA;&lt;p&gt;(This was a collaboration truly born on MathOverflow, as some of the authors have never met in person...)&lt;/p&gt;&#xA;" OwnerUserId="1946" LastEditorUserId="8250" LastEditDate="2022-07-10T12:15:43.860" LastActivityDate="2022-07-10T12:15:43.860" CommentCount="7" CommunityOwnedDate="2013-08-12T17:37:20.760" ContentLicense="CC BY-SA 4.0" />

For lower bounds, we present specific positions with transfinite game values of &lt;span class=&quot;math-container&quot;&gt;$\omega$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$\omega^2$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$\omega^2\cdot k$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\omega^3$&lt;/span&gt;. By embedding trees into chess, we show that there is a computable infinite chess position that is a win for white if the players are required to play according to a deterministic computable strategy, but which is a draw without that restriction. Finally, we prove that every countable ordinal arises as the game value of a position in infinite three-dimensional chess, and consequently the omega one of infinite three-dimensional chess is as large as it can be, namely, true &lt;span class=&quot;math-container&quot;&gt;$\omega_1$&lt;/span&gt;.&lt;/p&gt;&#xA;&lt;p&gt;The article is 38 pages, with 18 figures detailing many interesting positions of infinite chess.

Also, this might not be the only question an OP has, and the next ones will likely also fit better there on math.SE.

The main use case in practice seems to be to tag 'career' and 'advice' so the latter feels somewhat redundant then too.  &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorDisplayName="user9072" LastEditDate="2013-08-27T18:25:32.113" LastActivityDate="2013-08-27T18:25:32.113" CommentCount="0" CommunityOwnedDate="2013-08-27T18:12:45.300" ContentLicense="CC BY-SA 3.0" />

For example, it can be a summary of information provided in comments, or somebody has a half-way answer and hopes somebody can finish it, provide missing details, improve it in other ways and so on. On MO it is not used much in this form, but on other sites one can find answers to which numerous users contributed (a bit like our big-lists but that they do the list in one or a few posts). This is also documented by the fact that for CW-posts the point-threshold allowing others to edit is &lt;em&gt;a lot&lt;/em&gt; lower (100 vs 2k). And, thus, the OP also does not gain any points from such an answer, since it is (to be assumed/likely) that not all the credit for the post should go to them. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;For the same reason it makes sense to have this approach for the tag-badges, too. One could however envision that for badges this is different, since other score-based answer badges (nice, good, great answer and some others) are still given for CW answers.&lt;br&gt;&#xA;Personally, I do not have any particular opinion what would be better.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In any case, the behavior seems by design, it is documented in the following semi-official meta.SO post (part of the FAQ on badges) &lt;a href=&quot;https://meta.stackexchange.com/a/68395/228113&quot;&gt;https://meta.stackexchange.com/a/68395/228113&lt;/a&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;What counts is the score of non-CW answers (that are still present, i.e., not deleted).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Regarding Question 2: I think the hover-text does not really describe the actual situation, and I cannot see any good reason for it. Either it should be precise (as suggested in OP) or it should be simple/over-simplified and not mention CW at all.&lt;br&gt;&#xA;To mention CW but in an incorrect way seems like an oversight.

At the conference you'd think really carefully about what you say and brace yourself for the answer, hold your breath, and then ask. You'd have to be very careful when you ask, because the expert might have a Fields medal or be a rising superstar...they were, after all, invited to speak at a conference. So you only have one shot to get a good answer and the question should be formulated very carefully.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The community is now the expert, but the idea is the same.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;A second fortunate function of MO is the presence of the CW option. We can ask experts about their ideas that might direct or affect our, and the community's, approach to mathematics in general...as well as glean ideas that don't appear in papers. The answers to these are like the things speakers will mention in a talk that are complementary to, or that motivate, their results.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The second feature has developed despite the intention of the site playing the first role. I think this is mainly because a few high-profile members (like Bill Thurston) have opened the door to broader questions.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The strongest criticism of MO by certain of my colleagues is that MO might discourage young mathematicians (graduate students, for example) from thinking hard enough about their problems before looking for help with them.

Briefly put: long periods of being stuck after working hard with no progress at all are often critical to kick the subconscious into high gear.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Colleagues have also advised me to refrain from asking questions too frequently (understandably, if you regard MO community as a fields medalist...for example).

Certainly, a good compromise is to introduce a bound on the number of minor edits. Yet some edits, like the above mentioned, would be done better if all at a time, once and for all. So my modest proposal is the following:&#xA;&lt;strong&gt;Allow free edits on some special days.&lt;/strong&gt; How often, it has to be decided.

There are not few things in my life (mathematical and otherwise) that I did for some time an then stopped doing. Sometimes there was a good reason, sometimes it just happened. To give an example, for some time I really like to read the Notices of the AMS and read essentially all articles. Now, I read them rarely. I could not say why exactly. Or, for a while I browsed MathSciNet a lot, for fun mainly; I don't anymore. Also, my MO usage is not uniform. Sometimes I turned it down for a specific reason, sometimes I just have less time, sometimes I just do other things or do not happen to be in front of a computer that much. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;For specific users one could guess or sometimes also know for a fact why they stopped using MO. For some others it is not clear to me and for very few I would be curious. But this is not really a data-driven discussion but would be asking individuals about their motivation. I guess the reasons one might hear would be contradictory (from one user to the other).&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;In brief, it could be interesting to know some people's motivations, but I doubt we can infer them from data.

I think they would classify MathOverflow as an e-journal.

So this service would be suitable for a separate read-only &amp;quot;e-journal&amp;quot; archive of MathOverflow content, not for a site mirror (even if read-only) nor for permanent storage of MathOverflow data dumps. Their publication agreement can be seen &lt;a href=&quot;http://www.portico.org/digital-preservation/join-portico/for-publishers&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt; and the terms look very reasonable to me. Their pricing model is also very reasonable: so long as MathOverflow does not make \$250k in revenues, our annual contribution would be \$250.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;It appears that HathiTrust and e-Depot currently only accept &amp;quot;monolithic&amp;quot; documents such as books and cannot accept periodicals or similar objects. Archaeology Data Service only accepts documents relating to archaeology and history.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;The Global LOCKSS Network has an &lt;a href=&quot;http://www.lockss.org/about/how-it-works/&quot; rel=&quot;nofollow noreferrer&quot;&gt;interesting framework&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;This section describes how a LOCKSS Box works. Specifically, a LOCKSS Box performs five main functions:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;It &lt;strong&gt;ingests&lt;/strong&gt; content from target websites using a web crawler similar to those used by search engines.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;It &lt;strong&gt;preserves&lt;/strong&gt; content by continually comparing the content it has collected with the same content collected by other LOCKSS Boxes, and repairing any differences.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;It &lt;strong&gt;delivers&lt;/strong&gt; authoritative content to readers by acting as a web proxy, cache or via Metadata resolvers when the publisher’s website is not available.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;It provides &lt;strong&gt;management&lt;/strong&gt; through a web interface that allows librarians to select new content for preservation, monitor the content being preserved and control access to the preserved content.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;It dynamically &lt;strong&gt;migrates content&lt;/strong&gt; to new formats as needed for display.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;The system seems rather flexible but I couldn't determine what content formats they could support in their &lt;a href=&quot;http://www.lockss.org/support/prepare-your-content/&quot; rel=&quot;nofollow noreferrer&quot;&gt;archival units&lt;/a&gt;. To use that option, we would need to maintain our own archive (distributing content in a format that LOCKSS can support) and the participating libraries would each have a permanent and authoritative cache of our archive in their LOCKSS Box.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;The CLOCKSS Archive has a basic mechanism similar to the Global LOCKSS Network but the goal is not to provide continued access to the resource like some of the above. Instead, CLOCKSS is designed to publicly release an archive only after a &lt;a href=&quot;http://www.clockss.org/clockss/FAQ#How_does_the_CLOCKSS_board_define_a_trigger_event.3F&quot; rel=&quot;nofollow noreferrer&quot;&gt;trigger event&lt;/a&gt;.

I would be very happy with something very plain (such as what you see below the separation line when looking at the &lt;a href=&quot;https://mathoverflow.net/posts/1234/revisions&quot;&gt;revision history of a post&lt;/a&gt;).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I don't think there is any need to convert to PDF or any other format. The reasons for this are multiple. Markdown (the format MO posts are currently composed and stored in) is very compact and simple. It's perfectly readable even without markdown processing, so little is lost even if markdown goes out of fashion. Storing the math as LaTeX code is also generally better than compiling it and preserving the output. Alternately, LaTeX code could be converted to something which is standardized (such as MathML, for example) but LaTeX is pretty much a standard at this point. The only thing that might require maintenance is upgrading the character encoding from UTF to whatever comes next but that won't be a problem at all if and when it happens.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think the archive should include comments since many do contain much substance and some posts don't make sense without them. It's true that a lot of comments are just chatter but I don't see any good reason not to preserve those too and I can't think of a good way to sift through comments. Besides, knowing that their comments will be preserved forever might make users think a lot more before posting something inappropriate.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One contentious issue is how to handle deleted material. Archives typically work only one way: you can put stuff in but you can never remove anything. I can think of two ways of handling this: (a) make deleted material unavailable but still preserved, (b) clearly mark deleted material as redacted. Maybe there is another way?

I realized earlier today that everything suggested so far would also work if MathOverflow was a giant stack of loose leaf paper instead. Though this is a characteristic of excellent ideas that are both simple and versatile, it does suggest that we might not be considering the full extent of our options. I want to encourage users to think outside the box while considering this issue. The suggestion below is a small step in this direction and I my hope is that our collective creativity will lead to a solution which is as innovative and practical as MathOverflow itself.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;The idea that I will explain is motivated by several issues. One issue is the problem of deleted content that I raised in &lt;a href=&quot;https://meta.mathoverflow.net/a/817&quot;&gt;another answer&lt;/a&gt;. Similar issues are brought up by edits, revisions, later answers, etc. Another is that, although I expressed doubt about this, the fact that some users would prefer that only some of MathOverflow's content should be preserved suggests that this is a desirable feature. Finally, I realized during in my &lt;a href=&quot;https://meta.mathoverflow.net/a/816&quot;&gt;research on archiving agencies&lt;/a&gt; that they could find the total volume and regular flow of MathOverflow problematic.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This suggests that MathOverflow content could be archived only on demand. That is, there would be a MathOverflow Archive which stores a static copy of a question or answer in its current state when, and only when, a user requests it. Thus, if you want to cite something on MathOverflow, you make such a request for the content you want to cite, that content gets archived and your citation will always point to a static copy of that content.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This basically solves the deletion and editing issue since I doubt anyone would make such a request for deleted content and static copies remain as they are even if the original gets edited or modified in other ways. This also solves the selectivity problem since (presumably) only good content would be requested in this way. Finally, this also solves the volume problem since much less content would be archived by request.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This kind of archiving mechanism might also serve as support for other possibly desirable features such as an option to have the content peer reviewed (preferably in an open way using the &lt;a href=&quot;https://selectedpapers.net/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Selected Papers Network&lt;/a&gt;, for example) and, if the content is approved, it would get stored in a designated &quot;peer-reviewed&quot; part of the MathOverflow Archive (along with the referee report). Such enhancements would definitely give more credibility to MathOverflow as a micropublishing platform.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Scott pointed out that a defect of this approach is that few would bother making such requests. A potential solution is to have posts automatically archived as soon as someone presses the cite button to get a bibtex/amsref entry and have the urls there point to the proper place on archive.mathoverflow.net instead of the original.&lt;/p&gt;&#xA;" OwnerUserId="2000" LastEditorUserId="-1" LastEditDate="2017-03-17T10:13:04.480" LastActivityDate="2013-09-19T11:12:14.143" CommentCount="8" ContentLicense="CC BY-SA 3.0" />

(I took it from the rep league pages as this is easy, but places some limitations on the type of data.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;During 2010, 2011, 2012 there were 120, 103, 79, resp., users that got 2500+ points during this year. (Moreover 54, 37, 26 got 5000+ and 14, 9, 5 that got 10000+.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For 2013 there are 84 that already got 2000+ during the year and 21 that got 4000+. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So there is a quite significant decline of people that got 2500+ a year from 2010 to 2012 but preliminary data for 2013 suggests this trend does not continue for 2013 (though due to joining network it is a special year). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And this decline while for people on the site since a while their back-catalog of questions generates some 'free' revenue of points in subsequent years.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I also think there is quite a bit to the idea Scott Morrison proposed. The total number of people that are able &lt;em&gt;and willing&lt;/em&gt; to be sufficiently involved with MO to get 2500+ points a year might in the end not be that large.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In addition, the data given in OP might be slightly skewed for the following reason.

A better version of the question might be &lt;em&gt;&amp;quot;What are the best textbooks for an undergraduate number theory course?&amp;quot;&lt;/em&gt; or &lt;em&gt;&amp;quot;After an undergraduate number theory course, what should I learn if I want to study elliptic curve cryptography?&amp;quot;&lt;/em&gt; These questions aren't great, but they make it clear what the starting point is and what the goal is.&lt;/p&gt;&#xA;&lt;p&gt;Make sure it's clear exactly what your question is. It's extremely frustrating to read a long question which explains what the general problem is but doesn't contain an actual question. I usually resort to searching the body of the post for question marks, but it often doesn't help. After defining all your terms and motivating your question, consider visually distinguishing the final version of the question (see the formatting section).&#xA;&lt;br&gt;&lt;/p&gt;&#xA;&lt;p&gt;There are few things worse than a question which is too vague, too broad, or imprecise. Not only is it lazy to ask a vague or imprecise question, it's also rude. You're essentially asking somebody to do the work of figuring out what you want to ask, and then answer it, or to answer several possible interpretations of your question. Suppose somebody asks, &lt;em&gt;&amp;quot;What do you guys think about Foobar's new paper?&amp;quot;&lt;/em&gt; Even if this is exactly in my field, and I understand Foobar's paper better than Foobar himself, I have no idea where to start answering a question like that. Compare to, &lt;em&gt;&amp;quot;Does Foobar's regularization construction solve the Baz-Flipt Conjecture?&amp;quot;&lt;/em&gt; As an expert, this is something I can actually answer.&lt;/p&gt;&#xA;&lt;p&gt;When you're browsing MO, please don't vote up unfocused or imprecise questions. Such questions are as bad as (or worse than) homework questions; they waste everybody's time. If somebody asks, &lt;em&gt;&amp;quot;What's the deal with algebraic geometry?&amp;quot;&lt;/em&gt; you might say to yourself, &lt;em&gt;&amp;quot;Wow, I'd really love to see a great answer to that one. I'm going to vote it up.&amp;quot;&lt;/em&gt; &lt;strong&gt;But don't!&lt;/strong&gt; You're encouraging the wrong behavior. The great answer you're hoping for doesn't exist because there isn't a precise question. At best, somebody will answer, &lt;em&gt;&amp;quot;go read a survey article or a standard reference or the nLab page or the Wikipedia page.&amp;quot;&lt;/em&gt; Worse, somebody who is too kind and too generous with her time may spend a great deal of time and energy crafting an answer that might not satisfy the asker and that will be just a shadow of a proper survey paper. Such questions can't be reasonably answered in a few hours, even by an expert who knows the &amp;quot;answer.&amp;quot;&lt;/p&gt;&#xA;&lt;h2&gt;Do your homework&lt;/h2&gt;&#xA;&lt;p&gt;Before asking your question, try to solve it. Search &lt;a href=&quot;http://google.com&quot; rel=&quot;nofollow noreferrer&quot;&gt;Google&lt;/a&gt;, &lt;a href=&quot;http://en.wikipedia.com&quot; rel=&quot;nofollow noreferrer&quot;&gt;Wikipedia&lt;/a&gt;, and &lt;a href=&quot;http://ncatlab.org/nlab/show/HomePage&quot; rel=&quot;nofollow noreferrer&quot;&gt;nLab&lt;/a&gt;, check any references you can think of, and try to figure the problem out yourself (maybe even sleep on it). Doing so will help you break the problem down and understand it better. Even if you don't solve the problem, putting some work into it will often help you understand exactly what it is you're having trouble with, so you'll be able to ask a better question.&lt;/p&gt;&#xA;&lt;h2&gt;Break it down&lt;/h2&gt;&#xA;&lt;p&gt;You may have a specific problem you're trying to solve, and you may have done your research, but the problem might be a monster. Even if it's not a monster, you'll probably benefit from trying to break the problem into smaller pieces and posting one or two of the pieces on MO. To modify a quotation of Pólya, &amp;quot;If there is a problem you can't solve, then there is an easier problem you can't solve: find it.&amp;quot; You may worry that the the pieces are not interesting enough or are too specific to post on MathOverflow, but you shouldn't. It's much better to post a question that is too focused than to post a question that is too vague or too broad.&lt;/p&gt;&#xA;&lt;p&gt;It's okay to ask several questions related to a project you're working on, but try to limit yourself to one or two per day. Rather than posting all the parts of your problem at the same time, work through them one at a time. After all, the solution to one part may completely change your plan for solving the problem.&lt;/p&gt;&#xA;&lt;h2&gt;Consider different formulations of the question&lt;/h2&gt;&#xA;&lt;p&gt;Sometimes your question is boring, but you can often make it much more interesting by recontextualizing it.&lt;/p&gt;&#xA;&lt;p&gt;It could be enough to just ask if your question is false. For example, you might be reading a book when you come across &lt;em&gt;&amp;quot;Theorem 2.1. Every regular doodad is a widgit.&amp;quot;&lt;/em&gt; You read the proof, but you don't understand where it uses the hypothesis that the doodad is regular. Your question is &lt;em&gt;&amp;quot;Where does the author of this book use the regularity hypothesis in Theorem 2.1?&amp;quot;&lt;/em&gt; That is a boring question! But answering it is equivalent to answering an interesting question, &lt;em&gt;&amp;quot;Is every doodad a widgit?&amp;quot;&lt;/em&gt; That is, does the result remain true if you remove (or weaken) the hypothesis? Ask the more interesting question, and add &lt;em&gt;&amp;quot;I ask because I'm reading the proof of Theorem 2.1 of this book, which shows that regular doodads are widgits, but it looks like it doesn't use the regularity hypothesis.&amp;quot;&lt;/em&gt;&lt;/p&gt;&#xA;&lt;p&gt;Another thing you could try is to broaden the appeal of your question by generalizing it. Generalizing is actually a way of breaking the question down, since it amounts to removing hypotheses. For example, you might be trying to prove that some particular object X is a widgit. Asking &lt;em&gt;&amp;quot;Is X a widgit?&amp;quot;&lt;/em&gt; might not be a very interesting question. So you do your homework by looking for references and by trying to prove it in various ways. Eventually, you realize that the basic property of X that should force it to be a widgit is that it is a doodad, so you ask yourself, &lt;em&gt;&amp;quot;Is every doodad a widgit?&amp;quot;&lt;/em&gt; Of course not; it's easy to come up with doodads that aren't widgits. There must be some other property of X that will allow you to prove it's a widgit. Maybe it's because X is a &lt;em&gt;regular&lt;/em&gt; doodad. After thinking about it for a while, you think that it's plausible that every regular doodad is a widgit. If you can't come up with a proof or a counterexample, then you could ask, &lt;em&gt;&amp;quot;Is every regular doodad a widgit?&amp;quot;&lt;/em&gt; If you do, you may want to explain in a background/motivation section that you're really trying to show that X is a widgit.&lt;/p&gt;&#xA;&lt;h2&gt;Provide background and motivation&lt;/h2&gt;&#xA;&lt;p&gt;MathOverflow isn't just a place to ask and answer questions. It's also a place to read questions and answers, which is a great way to see what people in other fields think about, and to see how they actually think about it (not just what the polished papers look like). So when you ask for the help of those who know more than you, please also extend a hand to those who know less than you by explaining why you are asking the question. You'll get more votes, generate more interest, and are more likely to get your question answered. Explaining the motivation for a question may also help you gain a fresh outlook on the topic you're asking about. MO is meant to develop your ability to do mathematics, but also to develop your ability to communicate it.&lt;/p&gt;&#xA;&lt;h2&gt;Make your title your question&lt;/h2&gt;&#xA;&lt;p&gt;(But don't forget to restate it in the body!)&lt;/p&gt;&#xA;&lt;p&gt;Use your title to convey as much information about your question as possible. Since the tags already convey the general subject area of your question, the title should communicate the question itself as faithfully as possible. If necessary, leave out hypotheses in the title, and in the body of the question, explain why the question requires those hypotheses.&lt;/p&gt;&#xA;&lt;p&gt;Don't be afraid to make your question title long. Titles are allowed to be anywhere from 15 to 150 characters long. 140 characters (the length of a tweet) takes up about two full lines on the home page, so try to keep it less than that. But 140 characters is a lot longer than you might think. Too many people restrict themselves to 20 character titles. They're trying not to waste your time by making you read a long title, but they end up wasting more of your time because you have to actually open the question to see if it's interesting to you.&lt;/p&gt;&#xA;&lt;h2&gt;Format your question well&lt;/h2&gt;&#xA;&lt;p&gt;The readability of your question can often be greatly improved if you learn to use &lt;a href=&quot;/editing-help&quot;&gt;formatting commands&lt;/a&gt;, especially if your question ends up being quite long. Here is an example that contains a few good uses of the formatting commands:&lt;/p&gt;&#xA;&lt;p&gt;&lt;code&gt;## Background/Motivation&lt;/code&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;code&gt;A *doodad* is a thingumabob together with a sheaf of doohickies (which is usually called the *doo structure* on the doodad). A doodad is said to be *regular* if the sheaf of doohickies is regular. Intuitively, regularity makes a doodad &amp;quot;rigid&amp;quot; since information about the doo structure at a point can be translated into information about the doo structure at nearby points.&lt;/code&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;code&gt;A *widgit* is a whatsit which is flat (in the sense that its Plotsky curvature is zero). Showing that a space has a widgit on it is extremely useful because the flatness allows you to apply Foobar's gadget construction to prove many useful results about the space.&lt;/code&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;code&gt;----&lt;/code&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;code&gt;Based on the above intuition, it is natural to ask if every doodad is a widgit. However, the answer is clearly no, since a widgit is always regular, but [some example] is a non-regular doodad, so it is clear that we must impose a regularity hypothesis.&lt;/code&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;code&gt;&amp;gt; Is every regular doodad a widgit?&lt;/code&gt;&lt;/p&gt;&#xA;&lt;h2&gt;Background/Motivation&lt;/h2&gt;&#xA;&lt;p&gt;A &lt;em&gt;doodad&lt;/em&gt; is a thingumabob together with a sheaf of doohickies (which is usually called the &lt;em&gt;doo structure&lt;/em&gt; on the doodad). A doodad is said to be &lt;em&gt;regular&lt;/em&gt; if the sheaf of doohickies is regular. Intuitively, regularity makes a doodad &amp;quot;rigid&amp;quot; since information about the doo structure at a point can be translated into information about the doo structure at nearby points.&lt;/p&gt;&#xA;&lt;p&gt;A &lt;em&gt;widgit&lt;/em&gt; is a whatsit which is flat (in the sense that its Plotsky curvature is zero). Showing that a space has a widgit on it is extremely useful because the flatness allows you to apply Foobar's gadget construction to prove many useful results about the space.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Based on the above intuition, it is natural to ask if every doodad is a widgit. However, the answer is clearly no, since a widgit is always regular, but [some example] is a non-regular doodad, so it is clear that we must impose a regularity hypothesis.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Is every regular doodad a widgit?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Notice that the background/motivation is clearly labelled with a section header and clearly delimited by the horizontal rule, making it easy for experts to know what to skip or skim. The words being defined are italicized. After the nuances about why the question introduces some hypotheses, the precise final question is visually distinguished in a blockquote, making it easy to know exactly what constitutes an answer to the question.&lt;/p&gt;&#xA;&lt;h2&gt;A final note&lt;/h2&gt;&#xA;&lt;p&gt;Not every piece of advice on this page may apply to your problem, and it may even occasionally happen that you can make your question better by violating some rule laid out on this page. As with any writing you do, it is important to know what the basic rules are. If you violate one of them, it should be a conscious choice and you should be doing it for a very good reason.&lt;/p&gt;&#xA;&lt;h2&gt;Additional resources&lt;/h2&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Eric Raymond's &lt;a href=&quot;http://catb.org/~esr/faqs/smart-questions.html&quot; rel=&quot;nofollow noreferrer&quot;&gt;How To Ask Questions The Smart Way&lt;/a&gt; is directed at people looking to post problems to computer software/hardware forums, but much of the advice applies to asking questions on MathOverflow as well.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;User contributed content licensed under the&#xA;&lt;a href=&quot;http://creativecommons.org/licenses/by-sa/3.0/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Creative Commons Attribution-Share Alike 3.0 Unported License&lt;/a&gt;&#xA;with  attribution required.&lt;/p&gt;&#xA;" OwnerUserId="3" LastEditorUserId="-1" LastEditorDisplayName="user9072" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2016-02-10T11:17:48.787" CommentCount="12" CommunityOwnedDate="2013-09-25T10:25:29.043" ContentLicense="CC BY-SA 3.0" />

The only task that moderators are responsible for is dealing with flags. When community members flag a post for moderator attention or when certain user behaviors trigger some automatic warnings, moderators get a notification. Dealing with such a flag usually takes a few seconds. The vast majority of flags are dismissed because the community is perfectly able of dealing with them and often have by the time moderators get around to it. Sometimes more serious situations arise where a more substantial response is necessary but it still generally takes very little time to deal with those.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The workload is shared among all moderators and is completely voluntary. When I have a spare minute, I visit the site and clear all the easiest flags. If I have another spare minute, I might clear some flags that require more substantial actions if there are any (and usually there aren't any). Otherwise, I will leave those for the next moderator who comes along with another spare minute. Serious flags are very rare and the whole processing time adds up to two minutes or so per day. I'm also one of the more active moderators. Other moderators prefer acting as backup when others have to spend time away from MathOverflow or when something highly unusual happens.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are also a few maintenance tasks but these are very occasional and completely optional. I mostly do the tasks I enjoy doing, such as cleaning up the tag ecosystem, and I leave the tasks I find less enjoyable to other moderators. These maintenance task pop up very rarely but they can take more than a few minutes. A good technique to avoid burden is to ask community members to do these in their spare time. For example, I regularly post tag maintenance tasks on meta and the new review mechanism has made the task of deleting old off-topic questions almost entirely obsolete.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are also some perks to being a moderator. It's a great synergistic activity and you get to meet a lot of interesting people.

In other words, we'll express ordered preferences for the candidates, with only first-place votes actually counting but with rules for automatically transferring votes to backup candidates under certain circumstances (for example, if your first-place vote is for a hopeless candidate, then that candidate might be eliminated, which would transfer your vote to the person you ranked second).  Is this correct?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Probably there's nothing to be done about it at this point, but STV is a ridiculous voting system, so it would make me a little sad to have it used in MO.

For instance, computational-number-theory or transcendental-number-theory. Of course, one can then abbreviate these in some way but it seems odd to inflict this inconsistency on the tag-naming via an arbitrary limit. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Immediated use-cases would be to 'correct' the artificially abbreviate tag-names we already have. These are not very many but there are some.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Disadvantages could arise from longer tags taking up more space, this could be relevant in particular in the list of tags where (I think) the maximum possible length is taken into account for consistent layout (but this should not be a show-stopper). A non-disadvantage is the possibility of creation of too specific tags &lt;em&gt;due to&lt;/em&gt; the increased limit; it seems a lot more likely people will 'force' the tag they want to create in the given length (resulting in a tag that is harder to parse) rather than to abandon the idea of creating the tag.    &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I would assume there is no big technical problem here, except perhaps the layout-thing.

But to increase the existing one seems a good idea to me. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The idea of increasing this limit was brought up on occassion already (on meta.SO). It was not implemented but the case against it was not very strong either.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;A thing to keep in mind is that tags are displayed in the browser-tab so having them too long is sort of inconvenient. However, the tag displayed is the most popular one (by number of prior usages) so that this should not be a big problem.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;To sum up, I would consider it as a good thing if the tag-length was somewhat increased, maybe to 40; and if we can get strong support for this here, there might be a chance this gets done.  &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastActivityDate="2013-10-05T18:55:20.763" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

The duration of the election phase is adjusted somewhat, if I remember correctly, so the election phase is now longer than it would be if there had been a primary.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I've personally also doubted the way this works, as I'd like to give everyone the chance to read the answers by the candidates to the questions posed in the meta thread (or the chat townhall, which is no longer done in this way). But any delay in the election has disadvantages, and if you drag it on for too long you might lose more voters. I'm not entirely happy with the current way, but I'm also not convinced by any alternative that I've come up with or that has been proposed so far.&lt;/p&gt;&#xA;" OwnerDisplayName="user35354" LastActivityDate="2013-10-07T20:24:03.760" CommentCount="10" ContentLicense="CC BY-SA 3.0" />

Will there be more efforts to preserve the culture, or more to steer it toward things nearer to &quot;what a Stack Exchange forum should be?&quot;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I would prefer to preserve most MO culture apart from the points I have specifically enumerated on the &lt;a href=&quot;https://mathoverflow.net/election/&quot;&gt;election page&lt;/a&gt;.

My initial suggestion to the other moderators would be that they provide input on a gently worded message to the user (that I drafted, say) and presumably move forward with that. If this proved inadequate, I would consult with the other moderators on further steps.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(5) How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I view moderators as akin to judges, and would try to act accordingly. The first moderator's actions would be on &quot;the facts of the case&quot;, and I would limit any subsequent actions I took to &quot;questions of law&quot;, e.g., addressing failures in the moderation process itself. By this view (as there is no &quot;court of appeal&quot;), I would necessarily consult with all the moderators before taking concrete action. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(6) In your opinion, what do moderators do?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;IMO moderators ensure users follow the rules and norms of the community, and serve as the day-to-day managers of MO. To use a corporate analogy, moderators are officers rather than board members (the users of MO would be shareholders, and the board would be the corporate entity formed around MO). &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(7) A diamond will be attached to everything you say and have said in the past, including questions, answers and comments.

Is this a problem for MO? If so, what would you do about it as a moderator? See also: &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/1483/&quot; rel=&quot;nofollow noreferrer&quot;&gt;1483&lt;/a&gt; and &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/985/&quot; rel=&quot;nofollow noreferrer&quot;&gt;985&lt;/a&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;It's clear that women are underrepresented on MO and in the community as a whole. It's clear that underrepresentation in the community is a problem insofar as it is at least partially due to external forces, and IMO the evidence here is convincing. It is also a problem because it limits discourse--i.e., this is a problem both for women who would be mathematicians, and for the community itself. It is likely that both problems &quot;pull back&quot; to MO. There have been (at least old) meta threads discussing this, with no resolution. I can only say that I will remain mindful of such issues and do what little I can to ameliorate them as opportunities that are (or that are made) obvious arise.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(10) As MathOverflow is growing, the diversity of the moderator team might become an issue of interest.

I am certainly demographically typical: a male in the eastern time zone of the US. Professionally, I am atypical for MO as a mathematician in industry/government whose research is generally focused on applied questions of physics and/or computer science. &lt;/p&gt;&#xA;" OwnerUserId="1847" LastEditorUserId="-1" LastEditDate="2018-11-02T16:52:05.143" LastActivityDate="2013-10-07T23:14:23.263" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

Will there be more efforts to preserve the culture, or more to steer it toward things nearer to &quot;what a Stack Exchange forum should be?&quot;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;As a moderator, I would be conservative in the sense that I would oppose against possible&#xA;tendencies to get too close to math.stackexchange.com or otherwise to weaken the site's standards,&#xA;and in that I would actively seek to preserve the specific culture of MathOverflow.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In particular, I would seek to preserve the freedom to provide wordy comments,&#xA;including such which just kindly say &quot;Thank you!&quot; for an answer.&#xA;Further, I think the wide spectrum of styles in which questions and answers are&#xA;written is a great plus of MathOverflow, which definitely should be kept.&#xA;Also I am in favor of continuing to allow also smaller edits to improve the clarity&#xA;or appearance of a question or an answer.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think acception / rejection rates of questions should depend entirely on the quality&#xA;of the questions asked, and it does not make sense to try to get close to a certain&#xA;specific rate.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(3) What time zone are you in?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;UTC +1 hour in winter and UTC +2 hours in summer -- I live in Germany.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(4) How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;One of the first things I would try is to kindly explain the situation to the user by e-mail.&#xA;There is always a reasonable chance that a user is not aware of the impression his behavior&#xA;makes on other people, and that this already solves the problem.&#xA;If it does not, the appropriate way to proceed really depends on various things,&#xA;like how valuable the answers are and how bad the situation with the arguments and flags is,&#xA;and many more. In such situation I would discuss any possible action with my fellow moderators.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(5) How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Just let him know. There is always a chance that he closed / deleted the question by accident --&#xA;and if not, he may have valid reasons for doing so which I haven't seen.&#xA;Of course there may always be cases of doubt, but given what I have seen so far on this site,&#xA;the potential for conflicts here seems really minimalistic.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(6) In your opinion, what do moderators do?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I think the role of moderators is to impartially deal with any problems and misbehavior of users,&#xA;and to keep the site on-topic as far as this is not done by the community anyway.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Also, moderators perform general maintenance work like cleaning up tags, removing blatantly&#xA;off-topic posts etc. as well as administrative tasks like those related to this election.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Further, the moderators serve as contact persons for the user community,&#xA;and as such they answer any technical questions related to the site and provide assistence in&#xA;case of problems.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(7) A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light.

I think the question is in some sense&#xA;similar to asking somebody in what way joining the fire brigade would make him more effective.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(9) Do you think women are underrepresented in the MO community compared to the mathematical community as a whole?

Also, I would really have liked to see a female candidate&#xA;in this election.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One factor which I guess might make woman hesitate to participate is the design of this site,&#xA;which very visibly attaches numerical reputation scores to people, and which is possibly&#xA;perceived as pretty masculine by some.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;What I could do to increase participation of woman on this site is, seen realistically,&#xA;probably limited -- but in any case I would encourage more female participants to join, and would try&#xA;to reduce concerns with respect to rude behavior towards new users etc..&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(10) As MathOverflow is growing, the diversity of the moderator team might become an issue of interest.

We have a considerable number of users with essentially the same powers as moderators with respect to closing/deleting/etc (except, of course, that mods votes to do such things is immediately binding) and it is they who should be doing the closing, deleting and so on. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As a mod on M.SE I vote, in fact, much less to close/delete/&amp;amp;c than when I was a `regular' user (It should be observed that a mod cannot turn off his modhood) and I restrict those actions to obvious spam and other matters which require immediate action.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I do think that on MO we could be more aggressive voting to delete off-topic questions. I do think, too, that users should do this more, rather than mods!&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(6) In your opinion, what do moderators do?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Clean up stuff, turn comments into anwers and answers into comments, take care of migrations, and lots of other small janitorial work.

So I am not quite sure what is meant by &quot;what a Stack Exchange forum &lt;em&gt;should&lt;/em&gt; be&quot; beyond these two specific cases, or why the question is formulated as if to suggest there is a contrast between this &quot;should be&quot; and &quot;MO culture&quot;. But Gerhard Paseman's original question harks back to the many discussions of concerns about the merger, and how it might affect or shift the atmosphere of MO 1.0 (which many people, myself included, felt generally pretty comfortable with). I recall that quite a few people expressed some worries about the merger, based on their experiences with MSE, which I wasn't very familiar with at the time. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Positive characteristics that I prize in &quot;MO culture&quot; (&lt;em&gt;faute de mieux&lt;/em&gt;) and would like to see maintained are: a supportive atmosphere which values free and generous exchanges of information, scholarly care and precision in the formulation of questions and answers, a level of courtesy befitting a professional forum, and a somewhat low-key atmosphere in the matter of competition; in short, those characteristics I'd value in mathematics communities at large. It is that sense of professionalism which sets MO quite apart from MSE. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The MSE culture feels to me very, very different from MO culture, and I like it less. From what I have seen, many &lt;em&gt;hundreds&lt;/em&gt; of questions get asked over the course of a typical day (often with a new question every few seconds -- I'm looking at it right now), and there is a general hectic feeling of people rushing around to answer questions, and in my view not taking the time. There is a lot of competence on display there, but a lot of incompetence too. It also feels more competitive to me (who can type out an answer to a calculus question the quickest?) than MO. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;With the increased intermingling between the sites, it has become more urgent in my view to carefully preserve what is special about our culture here. I am committed to doing my part to maintain quality control; the idea that questions should be pitched at about or above the level of second-year graduate courses in a top-20 US research department, with attention to precision and due diligence, feels like about the right standard to me. I say this with particular regard to the increase in questions that get posted to MO because they haven't been answered at MSE; often they don't seem MO-appropriate to me. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I am aware that many feel that the MO culture is imbalanced and elitist, and in terms of fostering growth in the population of users, this is definitely a concern. Imbalance includes a heavy slant towards algebraic geometry and allied fields (I would say category theory, my own field, might be over-represented at MO!), and relatively slight representation of hard analysis and applied mathematics. I am not sure why this is -- but I do worry at times that questions in under-represented areas are often closed too quickly or zealously. On a few occasions I've wondered aloud whether a question is quite as trivial as some closers would make it seem.  My own record on this score is far from perfect, but I would for example encourage users, before they dismiss a question because it looks like 'homework', to at least make sure they can do the homework!  Or generally speaking, to be very careful in making judgment calls when reviewing questions outside one's area of expertise. We need to be more encouraging of under-represented areas; one small step might be helping to edit and improve questions first, before sending them off to closure-land (notice that we rely more on the stock closure reasons than before, where we used to leave helpful comments below the question). &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(3) What time zone are you in? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Eastern time in the United States. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(4) How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I fully expect that the present team of moderators has developed effective ways of resolving such problems. Most of the time, steady users seem to pick up on community norms as expressed in comments and when directed to the faq or to meta to discuss it further. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;For mathematically insightful users who nevertheless attract trouble, a reasonable approach would be a private email, appealing to the user's good sense and recognition that this is a forum essentially for professionals, with a matter-of-fact description of what seem to be the trigger points. In most cases, an MO user who produces consistently valuable answers will be familiar with how professional mathematicians behave IRL. Appealing to the professional's sense of decorum and probity should usually suffice. If the problem continues, then follow up by conveying the message that MO users are busy people and that further such nonsense really cannot be tolerated, and that moderators' patience is not unlimited. There are skilled ways of handling such things; as someone on the nLab Steering Committee, I have a little bit of experience here. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(5) How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I would send a polite private email message to the moderator that asks why the question was closed/deleted, and explain why I don't think I would have carried out the action myself. With the full expectation that all of the moderators are reasonable people who can see two sides of an argument. I anticipate few if any difficulties here. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(6) In your opinion, what do moderators do?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;This was actually answered by Scott Morrison in this thread: &lt;a href=&quot;https://meta.mathoverflow.net/questions/931/what-do-moderators-do?rq=1&quot;&gt;What do moderators do?&lt;/a&gt; Routine day-to-day activities include dealing with flags of one kind or another (spam, offensive posts, calls for Community Wiki which was an important aspect of our old &quot;culture&quot;, etc.), answering questions or clarifying policies at meta, dealing with occasional misuse of the site, often through discreet contact. I am a big believer in the StackExchange philosophy that the community should monitor itself, and that the actual function of the reputation system is to have those with more reputation carry more weight and responsibility in that monitoring, with the moderators being around to deal with more specialized tasks. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are other aspects to being a moderator (which I have yet to learn about) such as conferring with the StackExchange Team on possible feature requests, or fostering community relations and community outreach, or addressing problems such as possible structural biases or causes of under-representation of subject areas or populations, or maintaining growth over the long term, etc. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(7) A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light. How do you feel about that? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I feel fine about that. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In terms of what I say (present tense), it obviously won't make any difference in how I write mathematics. It would only affect my choice of words when I am writing on meta or commenting on behavior, since there I am no longer seen as speaking just for myself. But that's fine; I spend an awful lot of time on choosing my words anyway. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In terms of what I've said (past tense): a diamond symbol won't alter the fact that in the past, I've spoken only for myself. I see no problem with that. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(8) In what way do you feel that being a moderator will make you more effective as opposed to simply reaching 10k or 20k rep?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I would necessarily become far better informed about the operation of this site, and would spend more time considering how I might be of service to this site. In that sense I would be more &quot;effective&quot; than I am just by indulging in the pleasures of thinking about and writing mathematics, and voicing my opinion from time to time. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(9) Do you think women are underrepresented in the MO community compared to the mathematical community as a whole? Is this a problem for MO? If so, what would you do about it as a moderator? See also: &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/1483/&quot; rel=&quot;nofollow noreferrer&quot;&gt;1483&lt;/a&gt; and &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/985/&quot; rel=&quot;nofollow noreferrer&quot;&gt;985&lt;/a&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;There is no doubt in my mind that women are significantly underrepresented in the MO community, even relative to their representation in the mathematics community at large, and even if we assume that many of the pseudonymous users are women. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I do feel there's something wrong with that picture; it certainly doesn't reflect positively on MO, and it would be terrible if MO were helping cement institutional gender bias (quite in spite of the good and honorable intentions of many). The linked-to discussions, which I remember, included some valuable input from a number of women, touching upon the difficulties women mathematicians face in being taken seriously by male colleagues, or being shunned as too aggressive or competitive when the same behavior by men is often rewarded. There was some discussion of women preferring to post under pseudonyms, for various reasons. The general impression I get is that the problems as they are being reported are often subtle and not overt, but nevertheless cumulative and pervasive. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;No conclusions were reached at that time (indeed, some of these discussions just went downhill). It's just not clear at this point what we can or should do; as said, the problems as reported are subtle and difficult to point to. But what I might propose as moderator, with discussion and input from the community and internally between moderators, is first to hear the thoughts of more women on this topic. I propose designing a survey to solicit the opinions of female users of MO (and maybe branching out from there); it is not a difficult matter to set up a site where they can go to fill out the survey anonymously, and then the data can be more systematically analyzed. Maybe we'll then have better ideas of what we might try. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(10) As MathOverflow is growing, the diversity of the moderator team might become an issue of interest. As I understand, the present moderators have much in common, and women are, to say it that way, underrepresented. In which way do you think would you contribute to the diversity of the moderator team?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I would likely be the only moderator who is not actually part of academe or professionalized mathematics. (I left academe in 2001, and work as a full-time parent; mathematics is something I do on the side.) In that wise, I have some appreciation of what it is like for those who do not feel part of an academic in-crowd. (Also, as a &quot;Mr. Mom&quot;, I have a somewhat unusual angle on how it might be for many women, as they balance the demands of parenthood and maintaining a home with the desire to pursue their intellectual or artistic passions.) &lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="-1" LastEditDate="2018-11-02T16:52:05.143" LastActivityDate="2013-10-08T06:39:50.723" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

In what capacity?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Not applicable. (I am a professional mathematician, working in academia.)&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(2) Assuming a notion of &quot;culture&quot; &lt;a href=&quot;https://meta.mathoverflow.net/questions/908/2013-moderator-election-qa-question-collection/918#918&quot;&gt;as explained here&lt;/a&gt;, what would a newly elected moderator do to preserve it? Will there be more efforts to preserve the culture, or more to steer it toward things nearer to &quot;what a Stack Exchange forum should be?&quot;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;There are several aspects of this culture that I appreciate very much, and clash somewhat with the culture of other Stack Exchange sites I frequent. I hope these are preserved, and there will be no encouragement of my part to change them. An example that Gerhard &lt;a href=&quot;https://meta.mathoverflow.net/a/918/6085&quot;&gt;mentioned&lt;/a&gt; explicitly is wordy comments. Another seems to be the treatment of CW soft-questions, of which we have many excellent examples; we do not want these questions to overrun the site, of course, but the good ones have proved quite useful. I hope to help maintain the site standards, and the best way to do this is through example, in the posting of thoughtful questions, answers, and comments. I also appreciate how meta works and allows the whole MO community to become involved, with vivid exchanges we see in comments. &lt;a href=&quot;https://meta.mathoverflow.net/q/223/6085&quot;&gt;This thread&lt;/a&gt; I started to request reopen votes is a good example; the community clearly appears to appreciate it and use it, even though its approach seems discouraged by the SE system, as it was pointed out in comments.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Naturally, if it becomes clear that something we do in the site is not as effective towards our goals as it would be if we followed the model of other Stack Exchange forums, I would be supportive of that change. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And I hope I will be attentive enough to hear suggestions of other participants and colleagues that may help improve our experience. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(3) What time zone are you in?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;http://en.wikipedia.org/wiki/Mountain_Time_Zone&quot; rel=&quot;nofollow noreferrer&quot;&gt;Mountain Time Zone&lt;/a&gt; (Currently, UTC&lt;span class=&quot;math-container&quot;&gt;$-6$&lt;/span&gt;).&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(4) How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I expect these users would each pose unique challenges, and an all-encompassing policy may not be the best approach. When in such a situation, I would attempt to reach a consensus with the other moderators before proceeding. First, I would familiarize myself with the policies the current moderator team follows. This team is quite thoughtful and I expect they have experience with these difficult situations. We would then contact the person privately and explain the problem, hoping a solution can be reached with minimum conflict. If this proves insufficient, and the policies in place do not seem effective in a particular case, we would seek advice from the Community Managers.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(5) How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I would contact them privately (in a way that all moderators see the exchange and can participate), and would explain the reasons why I believe the decision was incorrect. I would ask them to reconsider that decision, and would try to start a dialogue leading to a common decision on how to handle similar situations in the future.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;That said, I expect to be open to be persuaded and change my viewpoint. Something I would definitely not do is to unilaterally undo their decision. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(6) In your opinion, what do moderators do?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Moderators help the community be informed, by answering their questions about the site, and providing assistance if needed. (Beyond matters that affect the whole community and are discussed on Meta, I have particularly contacted the current moderators on several occasions asking for clarification of site policies, or statistics that I have needed, etc, and their responses have been not just efficient but very useful.)  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The cleaning of flags seems to be the busiest activity, perhaps followed by the removal of off-topic posts (of which we have periodically quite a few). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Moderators deal with problems that may appear within the community, helping it stay a civil and inviting place. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Some tasks are administrative in nature. In his answers to &lt;a href=&quot;https://meta.mathoverflow.net/q/931/6085&quot;&gt;this question&lt;/a&gt;, Scott mentions the legal entity. I expect new moderators would be involved with it eventually as well. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(7) A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light. How do you feel about that?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I am fine with it. Of course, it will be a remainder to be thoughtful and measure my actions, but this is something I already try to do. I do not expect it will affect in any way the kind of questions, answers, or mathematical comments I post. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(8) In what way do you feel that being a moderator will make you more effective as opposed to simply reaching 10k or 20k rep?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;It is obviously a very different role than as a regular user, which does not mean it would affect my mathematical contributions (such as they are) to the community; MathOverflow is valuable to me beyond words. My being moderator would be a way of further contributing to the site and being more involved, beyond how I interact with it on a regular basis. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(9) Do you think women are underrepresented in the MO community compared to the mathematical community as a whole? Is this a problem for MO? If so, what would you do about it as a moderator? See also: &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/1483/&quot; rel=&quot;nofollow noreferrer&quot;&gt;1483&lt;/a&gt; and &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/985/&quot; rel=&quot;nofollow noreferrer&quot;&gt;985&lt;/a&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;It is an obvious problem (not just for MO). Solutions are difficult, short term solutions seem unrealistic. Unfortunately, I do not have a good answer; this is something that I have thought about at various levels for a while. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I hope to help promote the site (this seems particularly important), and to keep it a collegial and inviting place (we can certainly improve in this respect, I know of a few people who feel intimidated about participating). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Female colleagues with whom I have discussed MO but do not participate in the site do not seem concerned with these issues, luckily, but typically indicate that their field is underrepresented; there is the beginning of a good discussion about this &lt;a href=&quot;https://meta.mathoverflow.net/q/945/6085&quot;&gt;here&lt;/a&gt;. Some find the reputation system a turn off, though there are workarounds. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Again, this is a serious concern. As a moderator, beyond whatever can be done through promotion, I would be very open to suggestions. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(10) As MathOverflow is growing, the diversity of the moderator team might become an issue of interest.

Incredibly (I seem to live in denial) I am older than most(?) of the current moderators, and do not know most of them personally. I work in Idaho, at a primarily undergraduate institution, whose population is mainly of nontraditional age and first-generation college students. This provides me with a unique perspective that I expect may prove useful to the team.&lt;/p&gt;&#xA;" OwnerUserId="6085" LastEditorUserId="-1" LastEditDate="2018-11-02T16:52:05.143" LastActivityDate="2013-10-08T07:17:29.387" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

As a moderator I would act pretty much as I've acted all-along.  Our culture has some inertia and all the active users that have been present on MO for a few years contribute to it.  At the same time, the culture has always been somewhat fluid and tolerant of different perspectives. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(3) What time zone are you in?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Most often I live on the west coast of Canada.  For the next two months I'm in Germany.  I also travel to Japan and Australia quite often.  On top of that, provided I'm not teaching I keep fairly irregular hours.  So I have a fuzzy time zone.  When I'm teaching, historically I mostly used MO as a mechanism to ensure my brain is functioning in the morning -- I would always try to answer a question before my morning class.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(4) How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Some users are thornier than others.  To some extent we have to tolerate that, but there are some firm lines.  Generally speaking I think we like to keep things fairly quiet between the moderators and users having issues with the forum.  My impression is mostly moderators need only chat with these users, but in rare instances do they take strong actions like suspensions.  I think they've handled things quite well so far and I see no reason to change the culture on this.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(5) How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I imagine I'd chat with that moderator.  My understanding is there's a moderator chat room.  This might be a good time to use it. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(6) In your opinion, what do moderators do?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;There's a &lt;a href=&quot;https://meta.mathoverflow.net/questions/931/what-do-moderators-do&quot;&gt;thread&lt;/a&gt; on this.  Basically, moderators are much like any active high-rep user that frequents meta regularly.  They have a few added responsibilities and abilities to interact with the site, but by and large they're not very different from many regular users.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(7) A diamond will be attached to everything you say and have said in the past, including questions, answers and comments.

I think people who get a lot out of the forum should contribute to help keep it functioning and growing.  That is what I offer. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(9) Do you think women are underrepresented in the MO community compared to the mathematical community as a whole? Is this a problem for MO? If so, what would you do about it as a moderator? See also: 1483 and 985&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;We've had many conversations about this on the old meta, and I've participated in them fully.  In summary, it would be nice to find a way to increase participation but it's certainly not a pressing issue, for all we know there might be perfectly healthy reasons why there appears to be less female presence on the forum.  Perhaps compulsive MO use by male mathematicians is a little bit unhealthy?  I was talking with a very strong female mathematician just yesterday and she made the point that she does not want the expectations to compulsively use MO like many of the high-rep MO users do, as she does not like giving the impression that people can just ask her questions on a whim.  She objected to the &lt;em&gt;expectation&lt;/em&gt; that women should be major users of the forum.  She also likes to have big breaks in her day from the math world.  This all seems perfectly sane, healthy and reasonable to me. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(10) As MathOverflow is growing, the diversity of the moderator team might become an issue of interest.

I'm a white male of slavic descent, so by gender/ethnicity criteria I suppose I'm fairly typical for the math world.  I do try to encourage people from various backgrounds (engineers, musicians, software developers, etc) to participate on MO and I think anyone who has watched me participate on the forum over these years has seen that repeatedly.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I seem to talk with people about MO quite a bit in person, especially when I visit universities.  I've dragged many mathematicians onto the forum, like Ben Burton, Allen Hatcher, Paolo Salvatore and Stephen Bigelow.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;By subject area I'm a topologist.  While topology is not the dominant topic on the forum, it's one of the more common topics after algebraic geometry.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;But I'm not an American, nor a Berkleyite.  So that separates me a bit from most of the moderators.  &lt;/p&gt;&#xA;" OwnerUserId="1465" LastEditorUserId="-1" LastEditDate="2017-03-17T10:13:04.480" LastActivityDate="2013-10-08T12:17:05.510" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

Will there be more efforts to preserve the culture, or more to steer it toward things nearer to &quot;what a Stack Exchange forum should be?&quot;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Culture as I understand it is a product of the community, not of the moderators.  MathOverflow before the transition (based on my lurking on MO and meta) was trying to find itself, even in the midst of guidelines for behaviour, types of questions, quality and tenor of responses.  While the moderators tried to make a safe space for the community to grow, it was the community that tolerated or did not tolerate, used politeness or brusqueness, did brief or lengthy responses.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I would like to influence the community to preserve the ideals and the &quot;fun&quot; that appears in the early years of MathOverflow, but I also realize that MathOverflow is still finding itself.  I would prefer to steer MathOverflow to &quot;what a MathOverflow forum should be&quot;.  My hope is that there will be as much fun in the future as in the past. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(3) What time zone are you in?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt; I am currently in UTC-7 timezone.  (By no mere coincidence, so is the organism typing this.)&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(4) How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt; I would ask advice from other moderators as to how to approach discussing the user's behaviour with the user.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If no other tactic occurred to me, I would frame things in terms of keeping the community together.  I would point out how it is easy to fracture a community with divisive remarks, and how various previous forums failed from lack of sufficient moderation.  If the user had a point to be made, I would suggest how that user could communicate the point and still keep the community going.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I would also emphasize the user's contribution and say that the forum really needed the answers more than the flags, and ask them what could be done to ensure higher quality contributions from the user.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(5) How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;How I handle it would depend how strongly I felt about the event.  Take a major edit as an example: I would ask the other moderator why such an edit was done, and why another alternative was not done.  If I still felt that something wrong occurred, I would consult the rest of the moderation team.  I see no situation where I would perform any rollback or subsequent edit without support from part of the moderation team.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There is possibly the extreme situation where I stand on one side of the issue and the rest of the moderation team stands on the other.  If I felt the issue important enough, I would resign/quit my position as moderator.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(6) In your opinion, what do moderators do?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Primarily, moderators stamp out flames.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One of the reasons MathOverflow works well is the level of respect given to many.  Flame wars are almost extinct, and even mild expressions of discouragement and disrespect are often handled quickly.  It is crucial that MathOverflow have a subcommunity to watch for flames, and a moderation team to help put them out or steer them away.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Moderators can also have the job of encouraging participants to contribute in different ways, not just in maintaining atmosphere and quality content but also in determing and promoting forum goals.  I hope to see more of that, once the corporation MathOverflow decides what those goals are.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(7) A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light. How do you feel about that?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I have generally intended my contributions to be helpful to the forum.  Some of my more lighthearted comments might be read in a different way as coming from a moderator, so I may have some regret about that.  My future posts would likely have more of an official (hopefully still light) tone, commensurate with the position of moderator.  In general, I will feel that I need to have more care about being clear than about being entertaining.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(8) In what way do you feel that being a moderator will make you more effective as opposed to simply reaching 10k or 20k rep?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;As part of a moderation team, I would be in a position to encourage people on an individual level, as well as in a forum level, on how beneficial their contributions are, as well as to make suggestions on how they could help further.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Having some people acknowledge your contributions with upvotes is one thing; having a representative of &quot;the boss&quot; tell you how you are helping the community and how you could help it further has a different and perhaps more lasting impact.  It is this additional impact I could deliver as moderator.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;(9) Do you think women are underrepresented in the MO community compared to the mathematical community as a whole? Is this a problem for MO? If so, what would you do about it as a moderator?

As I understand, the present moderators have much in common, and women are, to say it that way, underrepresented. In which way do you think would you contribute to the diversity of the moderator team?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I think it is more important for the moderation team to have a unified vision than to have a diverse set of experiences.  MathOverflow is a resource to be used by everyone who appreciates it, but in actual fact it was intended for an audience with a specialized interest: promoting mathematical research, and doing so in English.  While it may be good to require diversity among gender status, nationality, or other spectra, it is more important that the moderator team encourage community behaviour so that the forum can prosper and be useful.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think that as more issues arise, the moderator team can ask for advice from other moderators at StackExchange to handle situations that require diversity.  I would share my experiences as a new user, as a non professional coming from industry with mathematical interests, and if needed, as someone half a generation older than many of the present moderators.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Looking over the moderation team and the current candidate roster, I see attitudes and positions that encourage diversity in the forum, and I see nothing that discourages diversity in the long term.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Background: I had been reading MathOverflow when I first learned about it from a sci.math.research post in 2010.  I have spent a lot of time reading posts on MathOverflow and on meta.mathoverflow.net.  I had some concerns over the migration of the forum from 1.0 to 2.0, and wondered how the community would change in the transition.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I found the easiest way to participate on the migrated forum was to create a new user account, handle &quot;The Masked Avenger&quot;.  I realized that this would be an opportunity to see how someone new to the system would be treated, and if there would be any substantial differences resulting from the migration.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I will shift &quot;I's&quot; now, and speak as the new user.  In the few months I have been active on this site, I have seen many reactions, some encouraging and some discouraging.  I think I have a better understanding as to why some users would gravitate to this forum and others would shy away from it.  I have gathered even more data since joining the election, and for those who are interested, I will share my experiences later.  However, I am not doing this for a lark.  I think there are situations where a moderator can operate effectively while using an anonymous handle in the forum.  I have no such expectation of being anonymous, nor of being unaccountable, to the MathOverflow moderation team or the StackExchange Network admins. If elected I will take steps needed to ensure I work smoothly with the moderation teams.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Shifting I's once again, one can ask whether &quot;The Masked Avenger&quot; is a sock puppet.  I have read over the debates, and note that on one hand, &quot;The Masked Avenger&quot; is technically a sock puppet, as it is not the first account I have used.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;On the other hand, other users have had more than one account for whatever reason, and my reasons have not been to abuse the system in any way.  Indeed, I have found value in the use, and am willing to share the value.  If &quot;The Masked Avenger&quot; does get elected, I will do my best to support that user in the moderation position, not because I prefer anonymity, but because of the support and feedback I can give to MathOverflow.&lt;/p&gt;&#xA;" OwnerUserId="35626" LastEditorUserId="-1" LastEditDate="2018-11-02T16:52:05.143" LastActivityDate="2013-10-16T00:02:11.650" CommentCount="6" CommunityOwnedDate="2013-10-09T01:43:25.610" ContentLicense="CC BY-SA 3.0" />

The common false belief question seems unlikely to get good new answers.

By the time we reach the stone soup phase, there's nothing we can do to refocus the existing answers on the original intent, even if the person who asked the question clarifies, so we might as well change the question.  If they were hoping for something else, then they can ask another, clearer question.  (I'm assuming the OP has seemingly abandoned this question.  If they are participating actively and trying to clarify their intentions, then we should not ignore their wishes.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I see two arguments in favor of editing:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;The &lt;a href=&quot;http://en.wikipedia.org/wiki/Broken_windows_theory&quot; rel=&quot;nofollow&quot;&gt;broken windows theory&lt;/a&gt; of MO.&lt;/strong&gt;  We want sensible, well thought out questions and relevant answers, while stone soup questions are often just the opposite.  For example, you may have a naive question that's unanswerable or trivial as written but on an interesting topic, with a discussion of this topic in the answers.  In that case it's better to clean up the question than to leave visitors with the impression that this is what MO is for.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Discoverability.&lt;/strong&gt;  If the answers have drifted from the original question or broadened it, then rewriting the question can make the answers easier to find, which is the whole point of posting them on this site.  In particular we should avoid question roulette, where you can't predict what sort of answers a question might have until you read them.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;Is there any reason not to do this?

(And perhaps also a comment explaining that it is bad manners to post the same question simultaneously on two sites, especially without mentioning this fact.)&lt;/li&gt;&#xA;&lt;li&gt;Left the question here for some time; sufficient for the OP to see the comments.&lt;/li&gt;&#xA;&lt;li&gt;After some time (maybe 2-3 days) the question can be deleted from MO. (Perhaps again the first user casting the vote to delete could leave the comment that it is deleted because there exists MSE duplicate and the question is not suitable for MO anyway.) &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;I think this approach might help to decrease number of unnecessary duplicated questions and perhaps it would make the work of mods a little easier.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;My suggestion is only for questions having no answers. (A question having upvoted or accepted answers cannot be deleted anyway.) And, as I have already said, it is not about questions where there was sufficient time between posting it on MSE and on MO.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt; I do think that in some instances there might be legitimate reasons why essentially the same question might be posted on MO and on MSE. For example, one of possible reasons is different level of expected answers. Usually greater mathematical maturity is expected at MO and the typical answer at MO might be too terse for some of the askers. But in any case, if someone decides to ask the same questions at the other site, they should explain their reasons for this and link to the other question. This problem has been discussed elsewhere and this is not what I wanted to address by this point. I have included this footnote mainly to stress the asymmetry between MO and MSE;  my proposal above is only about deleting the duplicates on MO. I am not sure whether the same argument would work as a reason for deleting a question on MSE.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;Unless the migration is done by regular users - if enough of them vote to close the post and choose the option to migrate to Mathematics.

In most of these cases, if the moderators had noticed the question earlier then it would have been CW'ed earlier, and no rep would have been earned.  So why not set things up so that when a moderator CW's a question, he/she has the option to remove all rep earned so far by both the question and its answers?  I think this should be the default setting.  There might be situations when a moderator CW's a question and for whatever reason does not want to affect rep earned so far, so that option should exist as well.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;ADDED LATER: In response to Todd Trimble's comment that users would find it annoying to lose rep: one could avoid giving them this rep in the first place. Have a button so that a user can flag a post for moderator attention while explicitly giving the reason that the post appears to merit the Community Wiki tag (maybe only allow users having at least a certain rep to flag posts in this way).  Once a post has been flagged in this way, have some notice appear below the post to say that the post is awaiting moderator decision on whether it should be Community Wiki.  After a post has been flagged in this way, record all subsequent votes for the question or its answers, but do not apply these votes to change anyone's reputation until the moderators have decided whether or not to make the post CW.  Keep track of the votes, and if the moderators decide the post is not CW then assign the corresponding rep.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think this would work because it often only takes a minute or two (or less!) for someone to post a comment saying a post should be CW.&lt;/p&gt;&#xA;" OwnerUserId="30412" LastEditorUserId="30412" LastEditDate="2013-10-21T00:33:53.840" LastActivityDate="2013-10-21T00:33:53.840" CommentCount="11" ContentLicense="CC BY-SA 3.0" />

You should very seriously consider the idea that the alternative would not have been that you got the same information under a real name but rather that you just did not get it at all.

Would you have prefered you would not have gotten the information at all? Also, a precise person might feel the need to quote you on MO also mentioning your display name, so 'alvarezpaiva', this is also sort of inconvenient. Maybe change that to the name as it apppears on you publications; you do not signe your papers with 'alvarezpaiva' I assume.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;re 2. This seems a bit orthogonal to the issue at hand. Certainly it could help in avoiding poor question to have some stricter sign-up process that involves some identification, but this would change the nature of the site. In addition it would be possible to do this while still allowing (essentially) anonymous and pseudonymous contributions. Enforcing real names in some vague way as done now, seems rather irrelevant.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;re 3. Maybe it is easier &lt;em&gt;once&lt;/em&gt;. But other than that (some) people under their real name get away with a lot more nastiness than an anonymous user ever would. One is a second or rather third class citizen here if not under ones realname, as is clearly said in the FAQs, and this is quite noticeable. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;re 4. Is there a shortage of &quot;dump questions&quot; getting asked also by people under their realname? Conversely, it is perhaps also of value to see that some anonymous users can make valuable contributions.

This is difficult in real life since people know about the paper from arxiv, talks etc.  But MO does offer a good way of testing this (at least until one's reputation increases) -- for pseudonymous users the readers are forced to evaluate the answers/questions at face value, while this is not always the case when the real identity is known.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Secondly, sometimes people on MO (anonymous or not) ask questions that they don't understand, or don't understand the answers given, or don't engage with the problem themselves fully.

I'd think that the situation might be quite different in other sciences, or in philosophy, etc., where coming to agreement on the &lt;em&gt;right&lt;/em&gt; answer is inherently thornier and more contentious. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;We're also lucky in that MO was so thoughtfully and carefully founded by some energetic and talented young people like Anton Geraschenko. (I hope no one minds my singling him out; I don't imagine anyone will.) Imagining Anton as a kind of hub for this activity, I think he and the people around him didn't just go at this casually, but developed a vision about what it would take to make this work. They must have talked and written each other back and forth a lot, and had the moxie to invest the requisite time and energy. I have no doubt they were aided by the vibrancy of the department at UC Berkeley (like their 20 questions seminar, now writ large by MO) and also by word-of-mouth and advance notice, e.g. through the influential blog Secret Blogging Seminar (founded mostly by grad students and past grad students at UC Berkeley). The fact that some really big names entered the arena (for example, blogging Fields Medalists!) also made a &lt;em&gt;huge&lt;/em&gt; difference. Is this somehow peculiar to the world of mathematics? I don't know. But anyway, by now we really have a stellar array of mathematical power. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So preconditions for success were excellent from the beginning, and as we all know, MO made a big splash on its inauguration. A lot of people then got a sense of how MO could benefit them as professionals, and wanted to keep it going (aided by the SE model where greater &quot;reputation&quot; means a greater share in moderation). (Again, you know all that.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The continued success of MO is of course another question, and cannot be taken for granted by anyone.

Quite difficult points of say number theory get closed when outsiders might have appreciated some explanation.

Sure, it happens that a question be closed as homework while it is in fact intrinsically legitimate, but it is up to the OP to clearly state the background and its motivation, not up to the people that might have the answer. Also, some questions are asked before the OP has thought them through; since asking a question is asking for busy people to help, it deserves a great deal of care.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Maybe we should seek a way to make closing less humiliating, if indeed it is felt that way.

MathOverflow is for mathematicians to ask each other questions about their research. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;There are some rather obvious overlaps between the two reasons, and I think we can perhaps optimize a bit. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Motivation 2&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As a moderator on Math.StackExchange, recently we have had some discussions about the closure of migrated questions. As you may already know: if a question is migrated to another site, and if it is closed there for anything other than &quot;Duplicate&quot;, the question gets bounced back to the original site, the migration canceled, the question now just put on-hold as generically &quot;off topic&quot;, and the user who asked the question originally may be none-the-wiser. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;You may be less likely to know that recently, due in part to the increased volume of questions, and in part to many members' preference to teach mathematics instead of handing out homework solutions, Math.StackExchange has implemented a &quot;Lack of context&quot; close reason, trying to encourage users to include the source/motivation of the mathematical problems that they are asking about, as well as any partial work that they have done toward resolving it. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Motivation 3&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Already at times we close the question as off-topic, only to leave a comment stating that perhaps MSE is a better place for it. My proposal makes for less typing by the users. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Proposal&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;We can keep the first off-topic reason (for questions that are not even mathematical), but change the second one to the following:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;MathOverflow is for mathematicians to ask each other questions about their research; general questions in mathematics should be asked at &lt;a href=&quot;http://math.stackexchange.com&quot;&gt;Math.StackExchange&lt;/a&gt;. &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Use&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In the spirit of &quot;teach a man to fish&quot;, I would advocate for using this custom close reason instead of direct migration when dealing with all but the highest quality (but unsuitable for MO) questions. This way the user learns to register a new account on MSE, and ask his questions there. And if his question is not of a sufficient quality for MSE, he will be told why &lt;em&gt;by members of MSE&lt;/em&gt;. Ideally this will keep users who do not care about research level mathematics from coming back to MO time and again. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Final remark&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Math.SE is rather more tolerant of questions, overall, than many other sites. In the past three months, MSE tried to migrate 10 questions to Physics with a staggering 70% rejection rate &lt;em&gt;[Edit: this I checked by hand, and the number is accurate. See comments below]&lt;/em&gt;, whereas Physics dumped 40 questions on MSE with only 5% rejected. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;MO is by far the largest migrator to MSE, with 185 questions in the past three months, of which &lt;strike&gt;21% were rejected &lt;em&gt;[Edit: this 21% may or may not be accurate. See comments below]&lt;/em&gt;.&lt;/strike&gt; 11% were rejected (see comments below). The fact that there are still, on average, two questions per day (just shy of 10% of the questions asked per day) which are migrated from MO to MSE (and I am sure a few others that are just closed as off topic without migration), means that we are still not getting the message across about the difference between MO and MSE.

I'll cite you as the source of course!&quot;. A answers &quot;sure!&quot;.&lt;/li&gt;&#xA;&lt;li&gt;Now B, as a MO user, is bound by the TOS. For instance, she cannot scan an annotated copy of her own lecture notes and publish it on her professional webpage, even if A agrees. &lt;/li&gt;&#xA;&lt;li&gt;This seems overly restrictive: why can't A, the original author of the answer, do whatever he wants with it, for instance relicense it and grant other people additional rights?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;I am not a lawyer and I hope I am reading the TOS correctly this time.

This however might be complicated to push-through, so a more modest suggestion: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Include &lt;em&gt;tag-synonyms&lt;/em&gt; in this automatic check. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;In this way, it would be possible to make the most common tags compatible (actually several of them would simply become compatible based on existing sysnonyms) while not changing the actual tags on either of the two sites.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;For the moment I tagged this &lt;a href=&quot;/questions/tagged/discussion&quot; class=&quot;post-tag required-tag&quot; title=&quot;show questions tagged &amp;#39;discussion&amp;#39;&quot; rel=&quot;tag&quot;&gt;discussion&lt;/a&gt;, so that opinions on the genaral matter can be voiced and other suggestion to reseolve it might be made. &#xA;Depending on how things progress I might change to &lt;a href=&quot;/questions/tagged/feature-request&quot; class=&quot;post-tag required-tag&quot; title=&quot;show questions tagged &amp;#39;feature-request&amp;#39;&quot; rel=&quot;tag&quot;&gt;feature-request&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Added: Thank you for the feedback.

A case has been made (see &lt;a href=&quot;https://meta.mathoverflow.net/a/946/2926&quot;&gt;here&lt;/a&gt; for example) that many people, for example graduate students or assistant professors, find the atmosphere at MathOverflow intimidating as it is, and thus withhold what might be nice questions. &lt;a href=&quot;https://meta.mathoverflow.net/a/1054/2926&quot;&gt;Some people&lt;/a&gt; even feel that awarding 5 points per upvote isn't &lt;em&gt;enough&lt;/em&gt; (it used to be 10 points in MO.1). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;On the other side, it has occasionally been recommended (without a view to enforcement) that people try first to get a sense of the culture by answering a few questions before asking a question themselves.

There are not a few users (including the OP, Stefan Kohl) who invest a good deal of time maintaining quality control. The occasional controversies that erupt are not currently, in my opinion, cause for serious alarm (in fact, they usually have a silver lining, in that those fine mathematicians who line up on one or the other side of the controversy show they really care about fostering the health of MO). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I don't think the questions of any one user has quite approached flood level.

In North America, especially at universities with the kind of budget that permits graders and TAs, there is usually a component of the final grade consisting of graded assignments.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;But, for example, in parts of Europe and South America, one's grade in a course is based entirely on exams (sometimes on a single final exam) and there is no notion of graded homework. There are sometimes suggested problems, perhaps gone over in a tutorial section, but perhaps not. Solutions are rarely posted.  And in some institutions in North America which do not have graders or TAs, problem sets are often only partially graded and solutions are not necessarily posted.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Clearly seeking help on ungraded assignments cannot be construed as cheating. It is conceivable that someone is working on an ungraded problem and is stuck or wants to check their work. Of course they should go see their professor, but if they are living far from campus (say at home) they might find it easier to ask online. Also, professors have limited office hours and there may be no TAs to talk to. Not all universities have the same resources for students.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So it is not automatically the case that an obvious homework question is a graded homework question and so it is not clear that all such questions constitute cheating. (Of course, sometimes the person asking the question says they need an answer in one day, and then it is more or less clear that they are trying to cheat.)  This then becomes, to some extent, a question of presuming innocence vs presuming guilt.

Also I would prefer not to unwittingly aid cheaters.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;But the real problem is that we have no way to know because cheaters don't advertise that this is graded homework or that they are not authorized by the prof to use internet resources.

But the Calabi conjecture example, and Sam Hopkins' answer, suggests a slightly different sort of question which might (&lt;em&gt;might&lt;/em&gt;) gain more traction. &quot;What are some examples of theorems which were eventually proven after initial attempts to prove them wrong?&quot; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It's probably not a great question posed this way, but the situation I have in mind is familiar in research: we have a statement whose truth we are unsure about, but we have our instincts about which way it goes, and this initiates a kind of proofs-and-refutations dialectic where our initial hunches and approaches morph into their opposite, e.g., efforts to prove something is false eventually yield insights into the fact that the statement is actually true. Or something like that. Anyway, I think some such question might have appeal, and would highlight one of those &quot;nontrivial twists&quot; (as you put it) that helps make mathematics interesting -- and it might also be free of the vagueness or opinion-based aspects that people are objecting to. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;About those other three questions: keep in mind that MO 'culture' is always evolving, and it's not necessarily the case that a question that was popular in 2010 would be popular (or even remain open) in 2014. I can see an objection that the first of those is opinion-based (what does 'surprising' mean, etc.). The second strikes me as less opinion-based somehow -- but I was personally disappointed by the quality of many of the answers. The third was not at all opinion-based or too broad: it was quite concrete, and unobjectionable IMO. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Comparing the merits of these sorts of soft questions (yours included) is largely a matter of taste; I have just given you my own personal reactions. It would probably be best not to try to argue matters of taste (e.g., which is &quot;more serious&quot; than the others). It would also be best not to press the idea that there is some sort of bias/discrimination against you personally; it would be impossible to prove, and such discussion would be headed in an ugly and fruitless direction. It is however true that there is a built-in looking askance and being more strict with 'soft' questions, since most users don't want MO to turn into a repository of subjective opinions, gossip, etc. (this speaks more to the broken windows metaphor). &lt;/p&gt;&#xA;" OwnerUserId="2926" LastActivityDate="2013-12-27T06:05:41.663" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

If anyone is interested in this, they probably should have a look at the MSE discussion. There is also a lengthy MSE &lt;em&gt;meta&lt;/em&gt; discussion attached to it. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course you (Makoto) are welcome to open a discussion about the suitability of this question for MO. If other MO users would like to see this question opened here, then by all means they should weigh in with an answer or comment. But I would like summarize some of the relevant MSE comments (and one of the comments at MO, which some can't see): &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;The question received substantial and authoritative response, notably by Andres Caicedo. Paraphrasing what he wrote (I ask the experts to correct me if I garble this in any way), for any universe $V$ that models ZF, FLT holds in $V$ iff it holds in the subuniverse of constructible sets $L$, because the statement of FLT is an arithmetic statement. But FLT is provable in ZFC (NB: without assuming an inaccessible cardinal according to all the experts; see the last discussion that Makoto links to). Therefore it holds in any model of ZFC, such as $L$, and hence it holds in $V$ as already mentioned. Since it holds in every model $V$ of ZF, it is provable in ZF by G&amp;ouml;del's completeness theorem. (This may be even too heavy-handed an explanation, but it's what I came up with.) &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Makoto edited his question to say he was not particularly interested in whether FLT could be proven without AC, but whether AC could be removed from &lt;em&gt;Wiles's proof&lt;/em&gt;. I don't know what this could mean if Andres's response (which I thought was excellent) is deemed inadequate by Makoto. At some point Makoto wrote at MSE meta: &quot;That a proof exists does not necessarily mean a human being can ever actually come up with it. Anyway, I'm asking whether AC can be removed from the Wiles's proof. Nobody has answered it yet.&quot; Andres responded to that a little later, and couldn't have been clearer: &lt;em&gt;any&lt;/em&gt; proof of an &lt;em&gt;arithmetic statement&lt;/em&gt; [my emphasis] like FLT, including Wiles's (which without doubt passes &lt;em&gt;inter alia&lt;/em&gt; through some heavy machinery, going into the proof of his Modularity Theorem), can be formalized in ZF, and the mechanism for doing that is well-understood by set-theorists. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;In what I thought was a real clincher for this line of argument, MO user Yury cleverly summed things up in his MO comment: &quot;As @FernandoMuro points out, it is extremely unlikely that the proof can be formalized in ZF without any changes. However, one can add just one sentence in the beginning of the proof to make it a proof formalizable in ZF: “all the formulas below are relativized to L (the constructible universe)”.&quot; It would be hilarious if Wiles had actually written a paper on FLT with that declaration appearing in section 1! His audience would think he'd gone mental. But note that such a meta-declaration would be in force all throughout the complicated argument, the Modularity Theorem, the whole schmeer in fact, and then just before the final QED which ends the proof of FLT, he brings in the remarks about arithmeticity and Shoenfield Absoluteness or whatnot. So his proof would be a few lines longer. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;I think what I personally take away from that is that Andres (and Yury at MO, but this is not visible to users with &amp;lt; 10k rep) gave a very satisfactory mathematical response to &lt;em&gt;the question as asked&lt;/em&gt;, as did Andr&amp;eacute; Nicolas in a very similar answer to the MSE question cited as duplicate. If Makoto (or anyone else for that matter) wants to ask a separate question about the use of AC in the proof of a (possibly) &lt;em&gt;non-arithmetical&lt;/em&gt; statement, such as what might possibly appear as some lemma buried somewhere in Wiles's opus, then that would be &lt;em&gt;an entirely different question&lt;/em&gt;. [It would not be reasonable to request that someone scour several hundred pages of Wiles's material just to ferret out such a sublemma -- that's the questioner's duty, and it's the issue underlying the &quot;too broad&quot; reason for the second closure.] &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And now a true &quot;meta&quot; comment, since much of the above has technical mathematical content which is arguably not the real concern of MO meta (but which may have been necessary to fully establish the context). The decision of François to delete the question from MO was made no doubt in part because it's been answered already. But &lt;em&gt;possibly&lt;/em&gt; also for the very pragmatic reason that, based on prior experience, many users will be completely put out by the prospect of seeing another discussion dragged out, arguing over the meaning of a question in a whole bunch of comment boxes, just as it currently played out at MSE.

One is to leave a comment on the original question or the disputed answer; however, I worry that this method has very low visibility unless it is carried out shortly after the response is posted.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Alternatively, one might edit the post, thereby bumping it up and drawing attention to it, or put up another post disputing the earlier one.

I don't find the general argument of &quot;reduction to $L$&quot; very appealing; I would like to think that results in the area are constructive (in some vague sense), relying more-or-less just on Kronecker's dictum about the natural numbers, and not on more abstract foundations.  Perhaps this is naive; nevertheless, I think it is real consideration for some number theorists.  On the MSE threads, zyx made various remarks that seemed to echo my thoughts on these matters.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Incidentally, I have answered many of the OP's questions on MSE, and never been treated with anything but appreciation and respect.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Added:  &lt;a href=&quot;https://math.meta.stackexchange.com/a/12329/221&quot;&gt;Here&lt;/a&gt; I discuss one concrete example of actual number theorists doing actual work to eliminate an apparently genuine appeal to choice in the Taylor--Wiles argument.

This goes deeper than even the IP and account level, it's extremely difficult to cheat or escape.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Recently, we've been being hit with &lt;em&gt;huge&lt;/em&gt; spam networks, and the system has been keeping 90% of it at bay. Unfortunately, the overall volume has significantly increased, which means the visible percentage (or that which must be flagged for the system to learn that it's evil) has grown in proportion. Where before you might have seen 2 or 3, you now see 10 or 13.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;We've been manually augmenting the system by feeding it information directly from queries, and I've done that in this case as well. Additional features are going into the system shortly that will help clobber even these massively distributed spam attacks, so that the visible percentage doesn't bump so high when they happen. This simply entails keeping track of those innocuous posts that spammers target for whatever reason, and dealing harsh score penalties to hosts and networks that spam them even once.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In other words, we're on it, and sorry about the noise. Just a graph of what's being kept out vs what's being flagged for context (as of right now):&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;img src=&quot;https://i.stack.imgur.com/TiC9B.png&quot; alt=&quot;enter image description here&quot;&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;By the time you've rejected a few edits, the spammer has probably already been stopped. What remains is, edits that are still in the queue made by them. It takes about 250 flags &lt;em&gt;from the entire network of 100+ sites&lt;/em&gt; to keep out up to 2k spam posts / edits daily (or, roughly 2 - 3 flags per community/site), which is pretty good. There's also a less than one percent error rate.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The thing to do here &lt;em&gt;might&lt;/em&gt; be to just drop any queued suggested edits when something is blocked (or at least whatever they contributed).&lt;/p&gt;&#xA;" OwnerUserId="35352" LastEditorUserId="35352" LastEditDate="2014-01-06T16:50:23.113" LastActivityDate="2014-01-06T16:50:23.113" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

Of course there &lt;em&gt;are&lt;/em&gt; mathematical theories involved in all these issues but often one just uses basic (but often not simple by any means) tools from these areas rather than doing any research in that respect. For questions from these areas there are better sites in the stackexchange network than MO (e.g. &lt;a href=&quot;https://scicomp.stackexchange.com/&quot;&gt;https://scicomp.stackexchange.com/&lt;/a&gt;, &lt;a href=&quot;https://stackoverflow.com/&quot;&gt;https://stackoverflow.com/&lt;/a&gt; or &lt;a href=&quot;https://physics.stackexchange.com/&quot;&gt;https://physics.stackexchange.com/&lt;/a&gt;).

I do not blame anybody for that - it's just that one has to remove all vague things (e.g. coming from underlying model inaccuracies or whatever) from the issue to get a crisp question for which a correct mathematical answer can be expected. However, this often helps to think about the core mathematical problem harder and that is often the first or crucial step towards a solution. It may well happen that something that starts as a question on an application of mathematics turns into a question in which nothing of the application can be seen anymore (and that may be a reason that one sees little questions which are obviously about some application).&lt;/p&gt;&#xA;" OwnerUserId="9652" LastEditorUserId="-1" LastEditDate="2017-05-23T12:37:20.967" LastActivityDate="2014-01-07T21:35:48.217" CommentCount="5" ContentLicense="CC BY-SA 3.0" />

And as long as some form of the correct exists in the record, I don't think having incorrect answers in anyway reflect poorly on the community as a whole. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A perhaps bigger problem is the situation when people upvote incorrect answers which they either have not checked themselves or that they do not understand. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now, this problem manifests a lot less for &lt;em&gt;mathematical&lt;/em&gt; questions and &lt;em&gt;mathematical&lt;/em&gt; answers, since the training of mathematicians often allow us to make educated guesses about the usefulness of answers even without following it through fully. And I certainly do not advocate voting only for answers one can personally vouch for. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;But for a soft (and borderline off-topic) question like the second one linked to above, which is about mathematics and poetry, the vast majority of the MO users would be mere amateurs.

If the problem is that we don't understand the physical chemistry, say the phenomenon of supercooling, or the effects of dissolved gases, then this is not an applied math problem, and we can't expect mathematicians to help. We need to ask chemists who study these things. Scientists generally know the basics of mathematical modeling, perhaps better than most mathematicians, so basic modeling issues are not a stumbling block. If the chemical phenomena are understood, but the mathematical model is too unreliable or slow, or we want a general explanation of the results, then it is an applied mathematics problem.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The original question was off-topic because it did not make the question an applied math problem.

I can think of two:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;a) A reference request for something that is properly outside mathematical literature. For example, biological examples of Lindenmayer systems are likely to be found in the biology section of the library, while a formal mathematical treatment might be in the computer science or mathematics sections.  Karnaugh maps for logic reduction and their history are usually relegated to texts treating digital logic design, and I can't think of any pure mathematical treatments or generalizations, although my experience may just prevent me from seeing such; I would expect most questions on Karnaugh maps that are reference requests to be off topic for this forum.  (On the other hand, &quot;Are there any mathematical analogues of Karnaugh maps for n-valued logic systems, and is there such analysis in the mathematical literature?&quot; would be a generalization I would be interested in seeing, even if the answer turned out to be &quot;look in the biology section of the library&quot;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;b) A reference request for a &quot;thing&quot; that is not concisely stated.  One of my favorite questions &lt;a href=&quot;https://mathoverflow.net/questions/37679/&quot;&gt;Erik Westzynthius&amp;#39;s cool upper bound argument: update?&lt;/a&gt; is a borderline example, primarily because of my desire to share the sieve argument; with a briefer summary of the argument I think it would serve as a good example.

At the same time, universal algebra is distinct enough that counterexamples in universal algebra would hopefully have their own flavor not found necessarily in questions like &quot;counterexamples in group theory,&quot; &quot;counterexamples in ring theory,&quot; etc. In that vein, I'd especially appreciate counterexamples about topics firmly within universal algebra - say, congruence lattices, or Mal'cev conditions - which nonetheless have &quot;something to say&quot; to other areas of mathematics.'&lt;/p&gt;&#xA;" OwnerUserId="8133" LastEditorUserId="-1" LastEditDate="2017-04-13T12:58:28.650" LastActivityDate="2014-01-08T22:33:58.637" Title="Is this question appropriate?

Of course, individual questions don't have to be worthy of an article, and they don't have to be about new mathematics. A typical example is, &quot;Can this hypothesis in that theorem be relaxed in this way?&quot;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I think the main source of confusion here is that the closure reason &quot;this question is not research-level maths&quot; is used for two different reasons:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;this question is off-topic because it's not about maths --- for instance, it's about physics, or about vacuum cleaners.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;this question is a reasonable math question, but it's too easy for a professional mathematician.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Maybe we need a closure reason that is a nice way to tell &quot;too easy, sorry&quot;. Something like &quot;this question could be readily answered using standard material for an undergraduate student in mathematics, and so it is not of interest here&quot;.&#xA;Or something better.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There is also an additional reason of confusion in this policy: what is an easy question for a graduate student in, say, algebraic topology, could be a challenging one for a professional researcher in, say, PDEs. A professional mathematician studying topic X could come up with a perfectly reasonable question about topic Y which is &quot;standard&quot; for someone using it, but yet not so easy that it is &quot;undergraduate material&quot;. This is material that would be considered &quot;too easy&quot; at a conference on topic Y, but not if you ask another mathematician.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Are these kind of questions on-topic? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I see many questions of this kind on MO. I suspect that even more of them are so, for an expert in the suitable field, and it's just that I cannot recognize them as such. In my point of view, this is often the kind of questions that I want to use MO for. It saves me the hassle of locating in person an expert on topic Y (which my university could not have) and going to his room to ask.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;On the other hand, I could see an argument also for banning this kind of &quot;reference-request&quot; questions. If it's something that you could have answered simply by locating a researcher in algebraic topology, any researcher, why are you bothering an entire online forum which includes several Fields medalists? &lt;/p&gt;&#xA;&#xA;&lt;p&gt;What would be left? Questions that are really &quot;research-level&quot;, as in: they would not be trivial even for an audience comprised entirely of experts in the field. This would reduce a lot the traffic here, and also sectorialize it a lot. Everyone would understand only a very small subset of the questions. Many more questions would be closed. Actually, this criterion would sound very close to &quot;if I you answer it, then close it instead of answering it&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are two overlapping questions maybe, one about the closing reasons, and one on MO's policies on what is to close.

It's often the case that your colleague down the hall can answer your question right away but sometimes your colleague has to think about it for a day or two. Sometimes that doesn't work and your colleague needs to ask a more specialized colleague in another department. Sometimes even that doesn't work and your seemingly innocent question might even reach the great guru...&lt;/p&gt;&#xA;&#xA;&lt;p&gt;MathOverflow is a lot like that, except that there is no layering: your question is seen by your colleague down the hall at the same time as it's seen by the great guru. Does that mean that you can't ask the same questions on MathOverflow as you would ask your colleague down the hall?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I like to think that whatever you would ask your colleague down the hall you could also ask on MathOverflow. That's a bit of an idealist attitude but I think it's fair. After all, MathOverflow is also about &lt;em&gt;answering&lt;/em&gt; questions.

However, if you would like to provide an answer then please go to the MSE link above or leave a &quot;comment&quot; at &lt;a href=&quot;https://mathematicsteachingcommunity.math.uga.edu/index.php/918/mathematical-thinking-skills-for-engineers&quot; rel=&quot;nofollow noreferrer&quot;&gt;The Mathematics Teaching Community&lt;/a&gt; where I have just posted a submission.

Yet, second, I think on MO it is by and large common understanding that the owner should have in most cases the last word  regarding their posts, and thus in case of actual conflict you should feel free to revert. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;For the particular matter. I think the tag perhaps appearing 'wrong' could be a misunderstanding of tagging-conventions of MO, which at the moment (due to software-upgrade) are still not that visibly explained as they used to be. As said by Emil Jeřábek it is strongly encouraged to use at least one  top-level tag for each (mathematical) question. These are the tags with two-letter prefixes that correspond to the math subject categories of arXiv, so this list &lt;a href=&quot;http://arxiv.org/archive/math&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://arxiv.org/archive/math&lt;/a&gt; The one used for retagging your question &lt;a href=&quot;https://mathoverflow.net/questions/tagged/ca.analysis-and-odes&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;ca.analysis-and-odes&amp;#39;&quot; rel=&quot;tag&quot;&gt;ca.analysis-and-odes&lt;/a&gt; seems the relatively most fitting to me (except one goes for the utmost general &lt;a href=&quot;https://mathoverflow.net/questions/tagged/gm.general-mathematics&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;gm.general-mathematics&amp;#39;&quot; rel=&quot;tag&quot;&gt;gm.general-mathematics&lt;/a&gt;).

As a rule of thumb, every question should try to use one of these tags along with more specific tags.&lt;/p&gt;&#xA;&lt;p&gt;The reason to use this categorization instead of &lt;a href=&quot;http://www.ams.org/mathscinet/msc/msc2010.html&quot; rel=&quot;nofollow noreferrer&quot;&gt;MSC&lt;/a&gt; is mostly historical, but the basic reason why &lt;a href=&quot;http://arxiv.org/new/math.html#notmsc&quot; rel=&quot;nofollow noreferrer&quot;&gt;the arXiv chose this categorization&lt;/a&gt; also applies here:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;h2&gt;Why not the Math Subject Classification?&lt;/h2&gt;&#xA;&lt;p&gt;The categories (or subject classes) of the xxx math archive bear some resemblance to the top-level sections of the Math Subject Classification (MSC) used by Math Reviews and Zentrallblatt für Mathematik. The two classifications, however, differ in their intent and history, and the math archive advisory committee decided that strictly following the MSC was unworkable. For example, Quantum Algebra, the most popular category in the math archive, has no counterpart in the MSC. It would be impractical, perhaps even counterproductive, to reorganize this category into MSC sections. Each category of the math archive must maintain a self-sustaining stream of new submissions in order to be useful; the committee decided that the MSC sections are in places too specific or too dated for this purpose.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;In fact, if we were to reorganize the MathOverflow tags, we would definitely prefer a classification where each major tag gets a steady flow of questions than a well-organized taxonomy like the MSC.&lt;/p&gt;&#xA;" OwnerUserId="2000" LastEditorUserId="-1" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2014-01-30T22:06:10.087" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

The main issue is that MathOverflow is continually updating and this hinders the citability of MathOverflow.

(E.g., assigning an ISSN, using volume or issue numbers, giving each post a DOI, etc.  Strictly speaking, DOIs have nothing to do with journal articles, but that's by far the most common use case in mathematics, so it would look like it's imitating journals.)  I think this could annoy people by seeming like MO is trying to become more citable by pretending to be something it's not.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;On the other hand, I think the citation issues can be resolved without any journal-like features.  Here's what I think is needed:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Some organization needs to commit to long-term archiving.  I'd recommend asking a university library and perhaps the Internet Archive.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;MO needs a policy for how to deal with deletion, since archiving is useless if material can be deleted from the archives.  The simplest solution is to preserve everything, but that has several drawbacks: you'll be preserving some total garbage, and crackpots may take advantage of it (even if their work is immediately deleted from the live MO site, it will be permanently accessible and citable in the archives).  On the other hand, you need to make sure nothing of any actual value could ever be deleted from the archives.  One solution could be to have a one-month window, and permanently archive anything that survives for a month on MO without being deleted.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;It's also worth thinking about what else should be preserved.  For example, comments certainly need to be archived, since they may play an important mathematical or historical role.  Presumably it's safest to archive everything, even relatively superficial things like upvotes on comments.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;MO's handling of permalinks is suboptimal for citations.  For example, the &quot;share&quot; link automatically appends the user ID for tracking purposes (to award badges to those whose shared links are widely used), which is probably not what someone looking for a citable link wants.  There are permalinks for every revision, but they are a little less obvious to find, and they link just to the specific text in question (for example, &lt;a href=&quot;https://mathoverflow.net/revisions/153731/1&quot;&gt;https://mathoverflow.net/revisions/153731/1&lt;/a&gt; requires several clicks before you can find any of the answers).  It would be great to have a more flexible system that archives snapshots at a given time while still making it easy to see any related material and to see any later updates.  For example, an archive link could show the whole question/answer page as it looked at the time that the link was made, with a prominent option to see what happened at other times.  Adding the full time to the permalink could be cumbersome, but all that's needed is a numbering of the changes made to each page.  Getting this working is not conceptually difficult, but it could be time-consuming, and there are a lot of irritating aspects.  (For example, how much do we care about things like chronology of votes?  Is it possible that someone citing an MO question would refer to something like &quot;the most upvoted answer&quot; in a way that couldn't be understood later without knowing the voting history and when the assertion was made?  On the other hand, changing the recommended permalink every time someone votes seems silly.)&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If all this is taken care of, then we could largely solve the citation problem by adding a &quot;citable link&quot; button, maybe even replacing the current &quot;share&quot;.  It would give an archival permalink together with a recommended citation format.  (Of course there might still be psychological issues regarding which sorts of citations are considered acceptable, but these steps would accomplish about as much as I think MO reasonably could in the near future.)&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;Monthly or weekly static versions would be much easier, and they would certainly help solve this problem, but the limited time resolution would be a problem.  Ideally, a &quot;citable link&quot; button should immediately produce an archival link that reflects what you see now, rather than an approximation that may be a week or more off.&lt;/p&gt;&#xA;" OwnerUserId="4720" LastEditorUserId="-1" LastEditDate="2017-04-13T12:58:29.980" LastActivityDate="2014-02-02T08:20:45.837" CommentCount="12" ContentLicense="CC BY-SA 3.0" />

Is it how the collapse of the Soviet Union affected Soviet mathematics?

Is it whether there are important lessons from the Soviet mathematics system that could be applied around the world today?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Whatever aspect it is, ask a question just about that one thing;  probably it's best if you edit your old question and ask for it to be reopened (put a moderator flag on it).

Then see how things go, whether you get good answers etc.  Then over time, you can ask questions about the other things you were wondering about; probably knowing the answer to one will help you to shape other questions.  You also might have some private discussions with the people who turn up to give answers.  I wouldn't ask a bunch of questions at once.

It is really helpful to make concrete proposals in order to advance the discussion. This is a tentative proposal for an archival mechanism that tries to address some issues brought up by Henry Cohn and others. I'm sure there are plenty of other issues we haven't discussed yet. So please don't think that this is an official solution, the discussion is just starting!&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What gets archived?&lt;/strong&gt; Archival units are individual revisions of individual posts in a manner similar to what is found &lt;a href=&quot;https://mathoverflow.net/revisions/153731/1&quot;&gt;here&lt;/a&gt; but with some additional functionality such as direct links to the &quot;live&quot; post on MathOverflow, links to other revisions of the post, links to the matching archived question or matching  archived answers depending on whether the post is an answer or a question, and other information described below.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Rationale&lt;/em&gt;: This is preferable to archiving page snapshots since it focuses on the actual information cited. Imagine a situation where user A gives a brilliant answer to user B's excellent question where user C had previously given an answer with a subtle mistake. After realizing their error, user C promptly retracts their answer by deleting it. However, user B takes a snapshot of user A's answer before user C's deletion and proceeds to cite it in an influential paper. That snapshot keeps being cited by other authors and user C's subtle mistake suddenly becomes a very embarrassing one.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;When is it archived?&lt;/strong&gt; Archiving would be done after a delay of $N$ days. Archival permalinks links would still be available right after posting but the archived version would be marked as &lt;em&gt;pending&lt;/em&gt;.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Posts that are deleted during the waiting period would be discarded from the archive.&lt;/li&gt;&#xA;&lt;li&gt;Posts that are put on hold/migrated during the waiting period would have their waiting period extended by $M$ days.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Rationale&lt;/em&gt;: The archival delay is to avoid archiving spam and other inappropriate content and to give users a reasonable chance at early retraction. Reasonable delays are $N = 10$ and $M = 30$.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What about deletions?&lt;/strong&gt; Once archived, a post is never deleted from the archive. However, archived posts can be annotated after some trigger events.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;When a post is deleted on MathOverflow, all of its archived revisions are marked as &lt;em&gt;retracted&lt;/em&gt; in a clearly visible manner.&lt;/li&gt;&#xA;&lt;li&gt;When a post is closed or locked on MathOverflow, some appropriate mark may be added near the link to the post on MathOverflow but the archived version would not undergo major changes.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Rationale&lt;/em&gt;: Archiving is fundamentally a one-way process: archived contents should never be deleted (unless there was an error in the archiving process itself). On the other hand, it is necessary to respect the users and the community. Annotations are the best we can do in this context.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Deleting, closing and locking are very different processes. Deleting is a clear retraction and needs to be clearly annotated. Closing and locking have to do with the functionality of the site and don't seem to need much annotation.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What isn't archived?&lt;/strong&gt; Post comments are never archived, neither are vote counts, view counts and similar ancillary post data.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Rationale&lt;/em&gt;: These primarily have to do with the functionality of the site. It is true that some of this content is worth archiving but it seems too difficult to sort. If a comment really does contribute significantly to the archival value of a post, it should be integrated into that post or promoted to a separate post.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;How does this integrate with MathOverflow?&lt;/strong&gt; A new citation button would be added below each post, separate from the share button. The button would give the archive permalink of the current version of the post (even if archiving is still pending) as well as properly formatted BibTeX and AMSref entries.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Rationale&lt;/em&gt;: Sharing and citing are fundamentally different; it is confusing to merge the two into one. The share button will still exist and it will give a link to the actual MathOverflow post. The cite button needs to be separate since it links to the archived MathOverflow post.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If archiving is still pending, it's the user's responsibility to ensure that the archiving process has completed before using the link in a citation. Since there is usually a very long delay before citations are published, this shouldn't be a problem in practice. In cases where the link needs to be immediately usable, the sharing link is probably more appropriate.&lt;/p&gt;&#xA;" OwnerUserId="2000" LastEditorUserId="-1" LastEditDate="2017-04-13T12:58:29.980" LastActivityDate="2014-02-02T19:09:15.057" CommentCount="5" ContentLicense="CC BY-SA 3.0" />

I feel that ultimately, it's the only way to really get a sense of that all important holy grail of mathematics learning: motivation. As for science, studying the history of the subject overlaps very strongly with appreciating the evidence for modern science, since all of the experiments and mathematical arguments were done a long time ago and are seldom mentioned nowadays outside of histories of the subject. And all of this is aside from the fact that the history of science is inherently interesting.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In both cases, mining the literature alone can be very difficult at times, and an SE would be really beneficial.

In this case it is better to close but still signal the other site, perhaps with additional instructions in comments. But even if no  instructions are given, it might be better in such a case the question is actually asked on math.SE rather than migrated, among others since then it can be closed, improved, reopened, which is impossible for migrated ones (as upon closure it is 'game over,' except perhaps for moderator intervention).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Thus, I can see why it is &lt;em&gt;in theory&lt;/em&gt; useful.

I do not understand this.

Or, to restore it, so that it can serve some potential future puropose. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If the issue is that the title alone did not make clear this was about a quote, a solution could be to change the title to something like: 'Source of the quote &quot;Graph theory is the scum of topology&quot; (or something very similar)'  &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastActivityDate="2014-03-10T13:34:38.883" CommentCount="3" ContentLicense="CC BY-SA 3.0" />

If 'scum' and 'slum' are equally offensive to those who flagged, then the present situation is no improvement and is in fact worse than before for reasons given by quid. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;But at this point I do sort of feel a mountain is being made of a molehill: the question is just not that important (I'd be surprised if the OP disagreed) and has warranted much more attention than it deserves. I also think it is clear enough what happened. Quid's suggestion at the end of his answer would be fine to me personally if the word 'scum' itself is not the problem, but I plan to make no more edits myself. (Not even sure why the Masked Avenger thought &lt;em&gt;I&lt;/em&gt; should be the one to do an edit in the first place, but I did so in an attempt to keep peace. Maybe it was a fail, as the kids today say.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I refuse to &lt;em&gt;delete&lt;/em&gt; the question: it was asked in good faith, and deleting would subtract reputation which I think would be completely unfair. &lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="2926" LastEditDate="2014-03-10T18:51:07.660" LastActivityDate="2014-03-10T18:51:07.660" CommentCount="2" ContentLicense="CC BY-SA 3.0" />

I imagine here that posts would not be about a single question or answer, but perhaps collect together and summarize discussion of a broader topic.

In the end some will be a bit happier but likely more a bit unhappier, not because it will be worse in an absolute sense but mainly as many do not like changes for such things. I am also not sure it will be really better; likely one will solve one (perceived) problem and unwittingly create another one. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;To give an example. Some (including me) feel that the &lt;a href=&quot;http://blog.stackoverflow.com/2010/03/the-great-reputation-recalc-begins/&quot;&gt;Great Reputation Recalc&lt;/a&gt; change to +5 for question and +10 for answer  (from 10/10) was perfectly reasonable and justified. (Disclaimer: I do realize that change favored me personally, but it is really not only or mainly this.) Some others think it is generally not good. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And, still some others have a sort of middle ground position, having some understanding for the change but feeling it should not have been applied retroactively. But then, I would have considered it as extremely problematic had it &lt;em&gt;not&lt;/em&gt; been applied retroactively but only taken effect at some point.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now, for the more specific idea of weighing votes. Personally I would have not much against this and it might have some merit though the precise details would be important to know to have an actual opinion. But then in any case I think it would increase an existing sentiment of some that there is some high-rep clique on the site that dominates everything or some such ideas (which are in &lt;em&gt;my&lt;/em&gt; opinion misguided, but then presumably in such users minds I am part of that clique so no surprise there).    &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A somewhat related idea that also got discussed and which I like would be to have points not depend in a linear way on votes. But, say the effect of an upvote decreases with their number (to damp/cap gains that feel out of proportion for things that happen to get popular) while that of downvotes increases with their number (on the grounds that while everybody can get some downvote on everything if there is an accummulation somewhere there should be an actual reason). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The daily reputation cap at 200 (from votes) goes somewhat in that direction. But, at least for a site like MO this does not work that well in my opinion.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;But in the end I feel the current system is somehow 'good enough.'

I've got mixed feelings about both. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It's important to look at the &lt;em&gt;utility&lt;/em&gt; of reputation, the degree that the system trusts you, before you consider the extrinsic motivation that it provides. Believe it or not, having someone arrive to your site and actually &lt;em&gt;type something meaningful&lt;/em&gt; is quite an achievement. Having someone type something that is both meaningful &lt;em&gt;and&lt;/em&gt; technically sound, however simple, is close to magic. I didn't realize how much this was the case until I started looking at tests that we run to try and understand visitor behavior. My point is, don't under-value contributions from knowledge that isn't rare, those are still valuable contributions.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Someone that has a track record of arriving to the site and doing meaningful, technically correct things &lt;em&gt;should&lt;/em&gt; be given additional privileges - you'd be silly to not give them more ways to participate. Despite the actual extrinsic motivation, which is having a number associated with you increase as you see more and more people agree with what you wrote - the underlying system of trust is particularly good at giving the more skilled more tasks.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The idea of &lt;em&gt;decaying&lt;/em&gt; votes becomes interesting because it would help to ensure that the most relevant, up-to-date answers would (at least, in theory) continue to rise to the top on older questions. On theoretical sites, or sites where domain knowledge is apt to change yearly, this becomes interesting. Your answer that got 400 up votes would need to continue to receive up votes as it aged, or answers that were receiving a greater velocity of votes would overtake it - a lack of votes on your answer being an indication that it isn't as relevant as it once was, and older votes would start falling off. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;That would also be the mother of all headaches to implement. It's just an interesting theory. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Weighted&lt;/em&gt; votes for clearly demonstrated rare knowledge would be &lt;em&gt;extremely&lt;/em&gt; cool, but not exactly accurate - if someone got 10,000 reputation for answering 100 very easy questions, does this qualify them to be a 'better' voter when it comes to those stellar answers that often go without due appreciation because they're difficult to understand? I'd tend to think not. If we did this, we'd have to do a combination of age, tag, rep, views to votes, snake oil and a little hoodoo - and it would still be wildly inaccurate and prone to abuse.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;These are theoretical problems that I &lt;em&gt;love&lt;/em&gt; to think about, because I do believe that an algorithmic solution could be in the midst. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Your best bet, for now is to share links to spectacular answers, and use the bounty system.

I have probably not asked any closable questions (well, until now, where I am in jeopardy of having this one closed).  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;From a relative newcomer's vantage, it's clear that discrimination is applied when deciding whether to downvote or close such questions.  I have seen similar-style questions survive (and thrive) when asked by a hot-shot yet closed when asked by a newbie.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For example, consider the &quot;journals&quot; category.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/questions/118202/should-science-authors-discourage-boycott-the-recent-push-for-author-ids&quot;&gt;This&lt;/a&gt; question&#xA;seems quite articulate to me, but it is the lowest score in the category and was closed (rightly) because it is too broad.  Its topic is not specific to mathematics.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/questions/36596/refereeing-a-paper&quot;&gt;This&lt;/a&gt; question&#xA;is also not math-specific, but generated a lot of interest and 155 upvotes.  It was eventually closed as no longer relevant after a good ride.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is easy to find more examples.  Pick a softish category or search term and sort by votes.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I fully admit that those on MO with high reputation have earned it by being good (sometimes &lt;em&gt;really&lt;/em&gt; good) at asking and answering.  And many of the newcomers can't even form a sentence.  There are examples (like the one above, though) where I can't explain the discrepancy in attitude.  The reputation breaks as expected.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Does anyone take the view that MO is neutral in its treatment of off-topic questions?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;edit:  I think I am backpedalling a bit from my initial view (which, by the way, was never intended to be aggressive... more tongue-in-cheek, in fact).  I can honestly say I see a correlation (a good word, Gil) between reputation-backed questions and forgiveness, but I now admit it's not a strong one.  Just today, I noticed a high rep user getting &lt;a href=&quot;https://meta.mathoverflow.net/questions/828/what-are-reasons-for-allowing-anonymous-voting&quot;&gt;trashed&lt;/a&gt; on metaMO because his question (which was fair) had a resounding and obvious answer (with which I agree).  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(This is off-topic, but I suspect most of the downvotes he got were from people saying &quot;NO!&quot; to his &lt;em&gt;question&lt;/em&gt;, rather than &quot;YUCK!&quot; to the &lt;em&gt;quality&lt;/em&gt; of the question.  I wish people would learn the difference.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Anyway, maybe the issue is simply that a question cannot be separated from its asker.

It should be noted however that Bill Thurston posed his question in a really thoughtful and reflective way, drawing on decades of his own deep experience, and already had high &quot;credentials&quot; for asking such a question (being the author of On Proof and Progress in Mathematics, among other things). So as soft questions go, his I think was rather high quality. It got a pass. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think that over the course of the existence of MO, there has been a trend toward becoming more hard-nosed toward &quot;soft questions&quot; -- this could be due partly to the rise of new users since the move to the SE platform.

Further, I have the sense that the community is not fully sure what the good ways are.  However, if you make it absolutely crystal clear that you have put in some work, and just need a &quot;bit of luck&quot; (hopefully an expert will remember something that becomes a crucial pointer) that requires little or no work on the part of the responder, I think that sort of question would be well received.  Also, you might check math.stackexchange, as the audience there might have the&#xA;person you want.  (Avoid simultaneous cross-posting, and do include references in &#xA;delayed cross-posting.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In order that the question be perceived as crystal clear, not only do I suggest following all the advice the FAQ and &quot;How To Ask&quot; pages offer, I also recommend the following structure for this type of question:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;Brief statement of specific request.  As an example &quot;Is X (stated below) present in the literature for algorithm-complexity?&quot;  (NOT &quot;Is this in the literature somewhere?&quot;)&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Background/Motivation of result.  &quot;In working on a group theory problem, I came up with this numerical relation that I decided to tackle using approximation methods I learned in my&#xA;PDE course...&quot;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Inclusion of definitions and other material to make sure X can be understood by&#xA;(relatively) nonexperts.  &quot;Using the notation of this on-line encyclopedia entry, Z is this graded&#xA;structure, double counting orbits of this action on the nth grade leads to relation&#xA;R_n, which suggests this dynamic approach Q to solve...&quot;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Clear statement &quot;X: the relations R_n are approximated (using metric M) to within&#xA;delta by solutions f_n to the differential system Q, using verifier algorithm A which computes delta.&quot;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Recap, as well as acceptable alternatives.  &quot;Is this in the algorithmic complexity&#xA;literature?  I am also interested in connections to number theory or statistics, even&#xA;if a minor variation of X (without algorithm A) is used instead.&quot;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Show a hint of your work. &quot;I've checked what I know of computational group theory, including X,&#xA;as well as basic texts Y and Z in discrete dynamical systems.  I have a snippet from&#xA;Knuth about Algorithm A, but not in relation to Q or f_n or R_n.&quot;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;By going through the process of arranging your question this way, ideally additional search terms will be suggested&#xA;to you that allow you to find it on your own (and report back your findings).&#xA;Even if it is not suggestive to you, it might trigger the desired &quot;bit of luck&quot;&#xA;in someone else.  However, you don't want to overwhelm the reader: present just&#xA;what you need to ask the question, and keep extra detail to the minimum and&#xA;off to the side, perhaps in the section of showing some of your work.

It's not directly about your larger point (that there is some biased toward not-closing &#xA;high-rep users' question), but it is about the too examples of questions you start your discussion with. Independently of who ask them, it seems to me perfectly reasonable that the first question got closed fast while the others enjoyed a long and successful life. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Indeed, it is true that the first question doesn't concern mathematics or the mathematical work. It can be asked, and answered uniformly in all academia, from Economics to east-asian studies to literature, etc. Moreover, it is a political discussion.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;But the second question is really about mathematics, specifically the process of refereeing research papers in mathematics. Make no mistake: it is true that the question does not mention explicitly mathematics, but this because it is understood on this site. (Simlarly, if I see asked whether your favorite group is compact here, I know this is not about the group of your friends on Facebook.) Consider for instance subquestion 3):&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;blockquote&gt;&#xA;    &lt;p&gt;3) What to do about papers with major grammatical or syntactical errors, but that are otherwise correct? Does it matter if the author is clearly not a native English speaker?&lt;/p&gt;&#xA;  &lt;/blockquote&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Of course the answer will be very different according to the field. If a paper is submitted in english literature, that it will matter a lot if there are grammatical error -- this is not acceptable for a paper in this field. On the other hand, the answer will also be different for a field like biology or other experimental science, where most paper have very little english text and consist mainly in a telegraphic description of en experimental device and tables containing the results of the experiments. Math papers are different: they are a discourse telling a story. Style matters, even if not as much as in a literary paper.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Or consider:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;5) What do you do when you do not understand an argument? Does it matter if it &quot;feels&quot; correct. How long should one spend trying to understand an argument?&#xA;  6) What to do about papers that have no errors but whose exposition is hard to follow?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;It is obvious that those question make sense only for mathematics, or closely related fields, where an argument is either correct or incorrect with no in-between, and where similarly one can either understand, or not, a proof.

For example, &lt;code&gt;&amp;amp;#231&lt;/code&gt; above should be replaced by &lt;code&gt;ç&lt;/code&gt;, &lt;code&gt;{\c c}&lt;/code&gt;, or equivalent. If you use special characters like &lt;code&gt;ç&lt;/code&gt;, make sure to use the LaTeX package &lt;a href=&quot;http://www.ctan.org/pkg/inputenc&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;code&gt;inputenc&lt;/code&gt;&lt;/a&gt; with the appropriate encoding option (e.g. &lt;code&gt;utf8&lt;/code&gt;). Also use &lt;a href=&quot;http://www.ctan.org/tex-archive/biblio/bibtex/8-bit&quot; rel=&quot;nofollow noreferrer&quot;&gt;bibtex8&lt;/a&gt; since the original bibtex only supports the 7-bit &lt;a href=&quot;http://en.wikipedia.org/wiki/ASCII&quot; rel=&quot;nofollow noreferrer&quot;&gt;ASCII character set&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Since bibtex tries to parse the author field and break it into parts (first, last,  suffix, etc.), it is best to remove the parenthetical link to the user profile since that will often break the parsing mechanism. (An alternative is to only use the link to the user profile and delete the name, but that might lead to sorting issues.)&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Since this post is an answer rather than a question, consider editing the title to make this clearer. You may also consider changing the URL to &lt;code&gt;http://mathoverflow.net/a/22350&lt;/code&gt;.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Bibtex traditionally only supports &lt;code&gt;YEAR&lt;/code&gt; and &lt;code&gt;MONTH&lt;/code&gt; of publication, which is unfortunately too coarse for MO posts. Fortunately, many styles do recognize the &lt;code&gt;DATE&lt;/code&gt; field; consider adding it. If the post has a nontrivial revision history, you may want to put a date other than the first posting.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If the bibtex style you use does recognize the &lt;code&gt;EPRINT&lt;/code&gt; or &lt;code&gt;URL&lt;/code&gt; fields, the visibly redundant entries containing the post URL could result in it being printed two or three times. Consequently, you may have to remove some of these entries to fit your preferred bibtex style.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If you use the &lt;code&gt;hyperref&lt;/code&gt; package, you could also wrap the URL in a &lt;code&gt;\url&lt;/code&gt; command in the &lt;code&gt;NOTE&lt;/code&gt; field so that it becomes clickable. Do not do this for the &lt;code&gt;URL&lt;/code&gt; field since styles that use this field will normally do the wrapping for you. A few styles support the &lt;code&gt;URLDATE&lt;/code&gt; field which, combined with &lt;code&gt;URL&lt;/code&gt;, is perhaps a better alternative than the given &lt;code&gt;NOTE&lt;/code&gt; field.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The use of the &lt;code&gt;EPRINT&lt;/code&gt; field is extremely style dependent. Some styles will do something reasonable with the field given above but many more will not. Maybe there is some style out there that understands &lt;code&gt;EPRINT&lt;/code&gt; but not &lt;code&gt;URL&lt;/code&gt;. Unless you use that style, it's probably better to remove the &lt;code&gt;EPRINT&lt;/code&gt; field.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;After all these recommendations, you get something that should work reasonably well with most styles:&lt;/p&gt;&#xA;&#xA;&lt;pre&gt;&lt;code&gt;@MISC {22350,&#xA;TITLE = {What are some examples of colorful language in serious mathematics  papers?

I temper this with the caveat that we can't answer (in general) questions about the nitty-gritty of Coq, but at least an 'in principle' answer should be of interest to most research mathematicians.

Are you thinking about some sort of fractal? or some sort of higher dimensional object? &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Next, what kinds of PDEs are you thinking about?

Are you faced with a particular PDE that cannot be easily resolved using conventional methods? Does the PDE itself has a good physical/computational interpretation that makes the CA implementation sensible? Do you know of any cases where CA has been applied to study any ultimately &lt;em&gt;continuous&lt;/em&gt; phenomena? Are there examples where CAs have been shown to be useful for solving a PDE, not necessarily on a closed curve?

It is near one year that the original real-name account of this user is closed. I don't want to discuss on the reasons of such a suspension here. I think we have qualified moderators and surely they had some reasonable reasons to put such a suspension on a user. The only subject which I want to talk about, is the possible negative consequences of these type of suspensions for suspended users, moderators and our community.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The main philosophy behind a permanent suspension is that &lt;em&gt;you are banned to use MO forever&lt;/em&gt; but unfortunately the anonymity rule in MathOverflow allows users to have several anonymous accounts and as a trivial consequence it is obvious that banning somebody form using MathOverflow loses its meaning and usefulness under this condition. This could encourage users to have several accounts which could be an ill-founded tradition in a professional community and a real treat for the quality of votes and reputations. &lt;/li&gt;&#xA;&lt;li&gt;Long time suspensions can encourage suspended users to show unnatural behaviors because they are expelled from community and they have no particular real-name account to improve. Their point of view is very different from a regular or short time suspended user. They may feel and act like a stranger in a xenophobic society. They may feel little responsibility on the quality of their posts and comments. &lt;/li&gt;&#xA;&lt;li&gt;Based on their responsibility, moderators should search for any abuses of anonymity rule and delete the corresponding accounts. This Tom &amp;amp; Jerry game on finding/hiding pseudonymous identities takes too much time and energy of both moderators and long time suspended users specially in the case of permanent members of community who show a special enthusiasm on contributing in MO.&lt;/li&gt;&#xA;&lt;li&gt;In some cases I saw that moderators deleted a wrong account just because it had a similar subject or writing style to the posts of a suspended user.&lt;/li&gt;&#xA;&lt;li&gt;Answerers will be hesitated to add high quality answers to posts of new anonymous users because it is possible that post belongs to a suspended user which will be deleted by a moderator very soon so the answerer will not receive an accept by poster or enough comments to  clarify the question.&lt;/li&gt;&#xA;&lt;li&gt;Frequent account production of a long time suspended user can increase the number of low reputation accounts which is not a positive parameter in MO public communications particularly in the point of view of those who are not completely familiar with this forum and are deciding to join or ignore us.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;As the consequence of above facts it seems long time/permanent suspensions don't help moderators to manage the contributions of an enthusiast permanent user. Allowing such users to have their own real-name identity on the site and managing domain of their contributions and possibly restricting it to mathematical subjects by more soft moderating tools and polices prevents the above problems and makes things more clear particularly when the user had a long time suspension before and have an invaluable set of experiences now. Naturally such a users reach a degree of professionality in their contribution style.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Furthermore adding a &quot;new chance&quot; option to our moderation polices associated with some sort of &quot;public apologies tradition&quot; will help both moderators and users to deal with a wider range of situations and build a new level of communication culture which doesn't consider an insult or suspension as an unsolvable taboo. I am sure this will produce a natural indirect moderation system which helps the community to improve the level of its meta discussions to more serious and less familiar subjects like suspensions. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Which one do you prefer as a community member?

I think many users see the logic of this type of reaction and support it, in the interest of preserving MO as a domain of high-level users (i.e., at the post-(under)graduate level and beyond). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;From this point of of view, it's easy to understand Alex's first point, that there is seemingly an inconsistency between wanting to dissuade the asking of a certain type of question at MO by casting a vote to close (or migrate), and at the same time lending some implicit encouragement to it by answering. I also see the logic of his second point. For example, if we take a more extreme situation where a hypothetical someone sees 4 votes to close as off-topic, swoops in to give an answer, and then casts the last vote to close as off-topic -- that would definitely leave a strange taste in the mouth for many. It could definitely strike one as a somewhat cheesy move, and certainly Alex's point, that at the very least it smacks of being territorial, would have validity. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;All that being said, after reading Michael's post, his intentions seem eminently honorable. It's good we're talking about this here.

To summarize my position in one phrase: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Avoid answering and voting to close at the same time, when in doubt answer. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I would in particular like to stress the second part since I feel quite some of the discussion focused on: &lt;em&gt;given I vote to close,&lt;/em&gt; can I still answer? and thereby somehow constructing a dichotomy between answering and not answering. But this is a bit a false premise. If  a question is not that bad, and no one proposed answering really bad question, there is no urgency to close it. If it is a clear case, it will be closed regardless of the answerer voting, if it is not so clear and would depend on this one vote, then perhaps it should rather stay open anyway. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now, why should one avoid it. I feel that the argument put forward by Alex B. is quite strong. The main purpose of closing a question &lt;em&gt;is&lt;/em&gt; preventing additional answers (on this site at least). I feel this is hard to reconcile with adding an answer; perhaps sometimes it is possible but in general it seems mutually exclusive. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Several focused on the migration aspect, so one does not really want to prevent answers but one wants to move everything elsewhere. Yet, especially this scenario I my opinion should be avoided as commented. And this is not just my opinion but (semi) official SE guideline, form the &lt;a href=&quot;https://meta.stackexchange.com/questions/10249/what-is-migration-and-how-does-it-work/10250#10250&quot;&gt;meta.SE FAQ on migration&lt;/a&gt; &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&lt;strong&gt;Avoid migrating answered questions.&lt;/strong&gt; The point of migration is to send the question to an on-topic place when it can get answered. If the OP already has an answer, then we've already defeated the purpose of migration and the destination site won't have anything to do with the question. Avoid migrating these questions unless they are of extremely good quality and risk deletion on the current site.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Now, MO does often not follow SE guidelines closely, but migration is inter-network and thus I feel we should not take this quite clear guideline too lightly.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So,  frowned upon on MO or not, at least voting to migrate and answering is (typically) in conflict with SE guidelines and thus should be avoided.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Additionally, it was brought up that the vote to close is to indicate that it is better suited for another site. Two points on this. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;First a detail but somewhat relevant: that something is better suited for another site is no valid reason to close. A question most be not suitable for this site to vote to close it (leaving dupe votes and similar aside).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Second, a vote to close is not even a good way to indicate something. It is not very visible, at least  not until it takes affect. And also as long as it did not take affect there is (normally) no way of knowing if an answerer voted to close or not. This is particularly relevant as normally I  take somebody answering as indirect endorsement of the question (and I feel this is somewhat widespread and came up in discussion frequently, like 'look xyz answered, the question should be alright'). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Thus if somebody wants to convey something else they better make this explicit, via a comment.

Unfortunately, the advisor also doesn't know the conventions of the field well enough to answer. One answer is that the advisor should e-mail friends of his who are closer to the relevant field, but this can take a long time without a good answer, even if he has such friends. He can simply encourage the student to submit the result and see what happens. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The question for us is, do we want &quot;post the question on MO&quot; to be a third option?

Starting with a perspective on mathematics as a theory of forms, Graßmann analyses in the most abstract way possible the general structures of concrete “conjunctions of forms”.&lt;/strong&gt; Here, he places special emphasis on “elementary conjunctions”, demanding they have module properties, that is, associativity, commutativity and an inverse and neutral element. The so-defined conjunction of the first order, or “formal addition”, is then followed up by an investigation of a conjunction of the second order (“formal multiplication”), for which &#xA;  he only requires distributivity with respect to formal addition. Graßmann directly posits &#xA;  the validity of the module properties for formal addition and distributivity for formal &#xA;  multiplication as the principles for constructing these conjunctions: “This generally is the &#xA;  way”, he wrote, “that initially, that is when no species of conjunction is yet given, such a &#xA;  conjunction of next higher order is defined.”&lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;Since Graßmann does not require the forms generated by conjunctions of the second order to be embedded in the fundamental domain, he can use this form of conjunction for the formal generation of new mathematical objects in the further course of the &#xA;  text.&lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;...&lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;&lt;strong&gt;After Graßmann has laid down the foundation for all mathematical disciplines by &#xA;  presenting these uniquely generalized group-theoretical and structural abstractions he starts with the actual presentation of his new mathematical discipline.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;What is the modern terminology for Grassmann's &quot;General Theory of Forms&quot;?

Avoid migrating these questions unless they are of extremely good quality and risk deletion on the current site.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Also the other points given there are good to consider, please, see the end for my take. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Migration has &lt;strong&gt;immediate deletion of the answers&lt;/strong&gt; as effect, and eventually the full post is deleted. &#xA;It is standing MO policy (and moderators intervene in cases of deviation brought to their attention) that questions with somewhat well-received and solid answer should not be deleted. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;This was discussed at length and with great passion at various occasions. (Practical considerations in the way put forward in Stefan Kohl's answer played no role whatsoever since at that time the effort to delete a question with or without answers was identically, and it is not that different now either, as soon as one falls outside auto-deletion.) Personally, I sometimes wished that this policy was less strict and allowed for more deletions. But, the policy is at it is. To vote to migrate with &lt;em&gt;the aim&lt;/em&gt; of answers getting deleted is &lt;em&gt;acting directly against a longstanding policy.&lt;/em&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Indeed, it seems even problematic to vote to migrate answered questions for any reasons as this deletion would be always a (possibly unwanted) consequence. But to give it as reason for migration is counter this site's policy on deleting answers (or rather on not deleting answers).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It should also be recalled that in these discussions the possibility of hosting the deleted content elsewhere was discussed, and was not considered as sufficient to then allow deletion of the content on MO. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;As alluded to in my comment and confirmed in this case it can happen that the status &quot;answered well&quot; arises only &lt;em&gt;after&lt;/em&gt; votes were cast, and one can imagine some other exceptional circumstances, but as a general rule one should not migrated answered question.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;On the general matter of migration:&lt;/p&gt;&#xA;&#xA;&lt;h2&gt;Three questions to decide if migration is appropriate&lt;/h2&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Is the questions off-topic for MO?&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Is the question a good or solid on-topic question on the target site? &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Will OP benefit from  answers they would get (in addition to existing ones) on the new site? &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;If the answer to the first two is not a clear &quot;yes&quot; do not migrate.

(It was only after looking at a relevant MSE post that I began to have a little idea what you were talking about.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Listen: we mathematicians are human and sometimes need a little help. My impression is that you were trying to say too much in your post without giving a proper introduction. I see that you've posted before here with something on convergents to $\pi$ that attracted people's interest, and so it's possible that you're onto something interesting here as well, only people are having a hard time seeing what it is. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Please don't accept this answer as yet; I want to have a crack at rewriting some of it a little later. Or, perhaps better yet, please open up another answer box and try this yourself. If people can understand it, then maybe we can consider reopening or asking anew. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;b&gt;Edit:&lt;/b&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Ah: the question was confusing to me because there was this mention of some curious coincidences involving ratios of certain &quot;permutation pairs&quot;, and counting the number of such and relating this to the Euler $\phi$ function; this seems to me to be the real meat of the OP's concerns. But if the OP just wants confirmation of his empirical formula for one such special ratio [and that is indeed the concrete question I see], then if I understand the question correctly, the answer is very easy and elementary (and thus would not be appropriate for MO). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So: my current understanding is that the question is about a formula which computes the analogue in any base $r$ (the &quot;radix&quot;) of the base 10 expression &lt;/p&gt;&#xA;&#xA;&lt;p&gt;$$\frac{9876543210}{1234567890} = 8.0000000729.$$ &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In other words, OP wants a closed form that calculates &lt;/p&gt;&#xA;&#xA;&lt;p&gt;$$\frac{\sum_{k=1}^{r-1} k r^k}{\sum_{k=1}^{r-1} k r^{r-k}}$$ &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As for references which deal with this, there must be many, but the techniques required can be found in any decent text which deals in generating functions as used in combinatorics and probability, such as Concrete Mathematics by Graham, Knuth, and Patashnik. The numerator can be evaluated as the value $f(r)$ of the function &lt;/p&gt;&#xA;&#xA;&lt;p&gt;$$f(x) = x(\sum_{k=1}^{r-1} x^k)' = x \cdot \left(\frac{x^r - 1}{x-1}\right)'.$$ &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The denominator can similarly be evaluated as the value $g(r)$ of the function &lt;/p&gt;&#xA;&#xA;&lt;p&gt;$$g(x) = x^{r-1} (\sum_{k=1}^{r-1} x^{-k})' = x^{r-1} \cdot \left(\frac{x^{-r} - 1}{x^{-1} - 1}\right)'.$$ &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So it just becomes a matter of a little tedious calculus at this point. I'll note that the author's $n$ here is $r-1$. His formula does check out for $n=9$, and I'm sure it's correct even without doing the tedious calculus. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;b&gt;Edit 2:&lt;/b&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Probably the author does want more than the elementary derivation above. My guess is that he is interested in counting how many ratios of &quot;pairs of permutations&quot;, where here &quot;permutation&quot; means an expression of the form &lt;/p&gt;&#xA;&#xA;&lt;p&gt;$$\sum_{k=0}^{r-1} \sigma(k) \cdot r^k$$ &lt;/p&gt;&#xA;&#xA;&lt;p&gt;where $\sigma: \{0, 1, \ldots, r-1\} \to \{0, 1, \ldots, r-1\}$ is a bijection, are exactly equal to the special ratio whose closed form was computed above. He notes in the mathematics.se post (that he links to) that there are $7$ (yes, $7$) such distinct pairs in the base $r = 10$ case.

Cano and described in detail in a Mathematics Stackexchange thread &lt;a href=&quot;https://math.stackexchange.com/a/283117/43208&quot;&gt;here&lt;/a&gt;, suggests that if we define two permutation pairs $(\phi, \psi)$ (with $\phi \neq \psi$) to be &lt;em&gt;equivalent&lt;/em&gt; if they yield the same rational value as displayed above, then $7$ is the size of the largest equivalence class, and this size is attained just for the value $\frac{a}{b} = \frac{109739369}{13717421}$ or its reciprocal. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;My questions have to do with what happens in other bases besides base 10. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&lt;b&gt;Question 1:&lt;/b&gt; For other bases $r$, consider permutations $\phi$ on the set $\{0, 1, \ldots, r-1\}$, and again define an equivalence relation on pairs of permutations $(\phi, \psi)$ (again with $\phi \neq \psi$) where two such are equivalent if they yield the same rational value &#xA;  $$\frac{\sum_{i=0}^{r-1} \phi(i)\cdot r^i}{\sum_{i=0}^{r-1} \psi(i)\cdot r^i}.$$ &#xA;  What is the size of the largest equivalence class? Calculations for the cases $r = 2, 3, \ldots, 10$ seem to yield, respectively, the sizes $2,2,3,3,5,3,7,5,7$. This looks suspiciously like one of the OEIS sequences &lt;a href=&quot;https://oeis.org/search?q=2%2C2%2C3%2C3%2C5%2C3%2C7%2C5%2C7&amp;amp;language=english&amp;amp;go=Search&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt;, all having to do with Euler's totient function. &lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;&lt;b&gt;Question 2:&lt;/b&gt; Which rational value $\frac{a}{b}$ represents this largest equivalence class? Putting $n = r-1$, my conjecture is that&lt;br&gt;&#xA;  $$\frac{(n^2 - 1) (n+1)^n + 1}{n(n+1)^n - n^2}$$ &#xA;  yields the maximum number, although there could be more than one such fraction. (Note that this is just a closed form expression for the base-$r$ expression $\frac{n\; n-1\; \ldots\; 1}{1\; 2\; \ldots\; n}$, analogous to $\frac{987654321}{123456789}$.) &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;There are other questions that could be asked; more can be found at the Mathematics StackExchange link given above. But this would be a good start for me. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;(End of suggested edit. What appears below is an earlier version of the question.)&lt;/strong&gt;  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As an introduction, consider, for example, the set S10, containing all possible distinct permutations of all digits in the base 10:&#xA; 1,2,...,8,9,0 &lt;/p&gt;&#xA;&#xA;&lt;p&gt;One could see that the one pair (P) in that set {9876543210,1234567890} yields the ratio &#xA;9876543210/1234567890=8.0000000729... &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Then one could find another pair in this set (S10), which gives the same ratio &lt;/p&gt;&#xA;&#xA;&lt;p&gt;7901234568/(0)987654312=8.0000000729... &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Then the question arises whether there are other pairs (P) in this set (S10) ,which have the same ratio ... &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Another question which arises - is there only one ratio in the set (S10) for which multiple pairs exist ? &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And, finally, same questions could be extended to distinct permutations in other (than base 10) sets (Sn).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Also (as shown later) it appears empirically (based on computer program results for bases from 2 to 10) that the value of the ratio could be expressed as &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(1)$$(n^2 (n+1)^n-(n+1)^n+1) / (-n^2+n (n+1)^n+(n+1)^n-n-1)$$&#xA; for n=1 ... infinity, where n = r - 1 and where r is the radix of the of the base.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For example, if one will take the base 10 (r = 10) &#xA;then n = r - 1 = 9 &#xA;If then one puts n = 9 into above formula - he will get 8.0000000729 &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So now I will try to generalize my questions as following:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;According to an exhaustive computer program written for numerical bases 2-10 (which searched for the maximum number of pairs with the smallest, less than &quot;n&quot;, but wherever is possible greater than 1 ratio(R) ), it was discovered that within an entire set of distinct permutations in the covered range, pairs (P) of permutations, which satisfy above stated conditions can be found, and that the number of such pairs is equal to: {2,2,3,3,5,3,7,5,7,...}.  If one would consider the latter as an integer sequence - it might be (according to OEIS A039649, A039650, A214288) related to phi, which is the Euler totient function .&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have derived the above empirical formula (1) for the values of the ratio (R) for pairs in the given base (based on conditions as defined above):&#xA;This formula (1) could be also expressed as A221740(n)/A221741(n),&lt;br&gt;&#xA;where A221740 and A221741 are OEIS's integer sequences (submitted by me) to cover the values, generated by the numerator and denominator (correspondingly), which appear in the formula (1).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Gerry Myerson rephrased my question as:&lt;br&gt;&#xA;given &quot;n&quot;, find integers &quot;a&quot;, &quot;b&quot; such that there exists &quot;k&quot; (greater than one, if possible, but less than &quot;n&quot;), so &quot;ka&quot; and &quot;kb&quot; use all n &quot;digits&quot; exactly once when written to base &quot;n (with a leading zero permitted). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In Gerry's terms &quot;n&quot; is what I call radix &quot;r&quot;, {ka, kb} is what I call to be a pair (P). What he defines as &quot;k&quot;, I call ratio (R) - it could be expressed as k=i/l, where both &quot;i&quot; and &quot;l&quot; are integers. For each &quot;n&quot; the value of &quot;k&quot; is different. As empirical formula shows, both &quot;i&quot; and &quot;l&quot; (and therefore &quot;k&quot;) are functions of &quot;n&quot;. In each covered base &quot;n&quot; (from 2 to 10) several pairs, satisfying that &quot;n&quot; specific ratio (&quot;k&quot; or &quot;R&quot;) were found - the number of pairs for given &quot;n&quot; is also a function of &quot;n&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Based on obtained results two following conjectures are made:&lt;br&gt;&#xA;1) Every complete set of all distinct permutations in any numerical base (radix) r contains some prime number of pairs (P) with the ratio (R) as defined above.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;2)The ratio (R) could be calculated by the (empirical) formula (1).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If anyone has references already covering this particular topic - please provide them - I will appreciate such reference.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;PS My analysis of results on this issue are described in&lt;br&gt;&#xA;oeis.org/A212958&lt;br&gt;&#xA;and in&lt;br&gt;&#xA;&lt;a href=&quot;https://math.stackexchange.com/questions/210578/permutation-identities-similar-to-7901234568-9876543210-cdot-1234567890/283117#283117&quot;&gt;https://math.stackexchange.com/questions/210578/permutation-identities-similar-to-7901234568-9876543210-cdot-1234567890/283117#283117&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Could someone provide analytical proof or disproof of my conjectures stated above?&lt;/p&gt;&#xA;" OwnerUserId="55853" LastEditorUserId="-1" LastEditDate="2017-04-13T12:19:34.473" LastActivityDate="2014-07-16T18:25:27.853" CommentCount="7" ContentLicense="CC BY-SA 3.0" />

Social network analysis is used to examine the interactions among users over a period of two and a half years. We describe relevant aspects associated with its behaviour as a result of the dynamics arisen from users participation and contribution, such as the existence of clusters, rich–club and collaborative properties within the network. We examine, in particular, the relationship between the social achievements obtained by users and node centrality derived from interactions through posting questions, answers and comments. Our study shows that the two aspects have a strong direct correlation; and active participation in the forum seems to be the most effective way to gain social recognition.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Page 10 has a description of the clustering that can be observed on MathOverflow.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Most of the clusters are quite small given that 61% of the clusters has just 2 users, see fig. 3(a). The map representing the 105 clusters in the network displayed its 6 biggest groups (denominated as G1, G2, . . . , G6) and the small box in the bottom right corner contains 99 clusters with a total of 297 nodes. Also, the 6 clusters have 97.5% of the total users in the MathOverflow network. The subgraphs (clusters) diameter, average geodesic distance and density were calculated for the 6 clusters, in order to characterise them. Cluster G2 has the same diameter than the whole network (7 edges). Clusters G6 and G3 have a diameter of 11. The six clusters show a density lower than 0.006 which is bigger than the density of the whole network (0.0014), although they are significantly low given that the density provides the ratio of direct ties in the network to the total of possible direct ties [28]. The 6 biggest clusters have a small proportion of users with the highest degree values and the highest upvotes counts, with a relevant proportion of users with low degree value and upvotes as followers. The users with a degree higher than 500 or upvotes higher than 750 or with the highest reputations are located only on the 6 biggest clusters (see fig. 3(b)). In contrast, users who have achieved a reputation of 1 (which is given when users input their personal details on the community web page) are located in the biggest clusters as followers of the main users and in the small clusters, Fig. 3(c).&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;&lt;img src=&quot;https://i.stack.imgur.com/L5tg8.png&quot; alt=&quot;MO Clustering&quot;&gt;&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;This is a comment that's a bit too long. It looks like the author did try to correlate clusters with tags: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Specific subgroups in the network were identified based on the tags (topics) the users marked their questions with. When analysing the 3 subgroups with highest number of users (AG–Algebraic Geometry, SQ–Soft Question and NT–Number Theory) they appear to have similar network characteristics as the whole network. These subgroups contain 20%, 19% and 18% of the total users in the network respectively. The subgroups AG and NT have a diameter larger than the original network, which means the farthest two nodes in AG and NT are more distant; whereas the SQ subgroup has the same diameter as the original network (see Tab. 2).&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;It may seem unusual that the authors identified &lt;a href=&quot;https://mathoverflow.net/questions/tagged/soft-question&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;soft-question&amp;#39;&quot; rel=&quot;tag&quot;&gt;soft-question&lt;/a&gt; as a subgroup but note that their methods are purely algorithmic and not based on any predefined mathematical taxonomy. On the other hand, it is not surprising that the SQ graph is similar to the whole graph while AG and NT graphs are somewhat different.&lt;/p&gt;&#xA;" OwnerUserId="2000" LastEditorUserId="2000" LastEditDate="2014-09-09T23:43:55.853" LastActivityDate="2014-09-09T23:43:55.853" CommentCount="5" ContentLicense="CC BY-SA 3.0" />

I was writing stuff as the talk was being given: basically, a long list of all the things said that I did not understand. At the end, I asked the speaker to provide me with a take-home message suitable for &amp;quot;my level&amp;quot; of current understanding (&amp;quot;how would you present your talk as a 2 minute movie trailer?&amp;quot;). He was &lt;em&gt;very&lt;/em&gt; polite and gracious, and gave me the following trailer.&lt;/p&gt;&#xA;&lt;p&gt;Let's say you have a set &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt;. Inside &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt;, you have a point &lt;span class=&quot;math-container&quot;&gt;$x$&lt;/span&gt; where you start off at. Now, you also have a function &lt;span class=&quot;math-container&quot;&gt;$f: S \rightarrow S$&lt;/span&gt; (is that how I correctly write &amp;quot;maps from something in &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt; to something else in &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt;&amp;quot;?). So each time you apply &lt;span class=&quot;math-container&quot;&gt;$f$&lt;/span&gt; to &lt;span class=&quot;math-container&quot;&gt;$x$&lt;/span&gt;, you land at another point inside &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt; (&amp;quot;duh&amp;quot;), but what if you keep landing inside a closed subset of &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$Y$&lt;/span&gt;? Not just once (&amp;quot;duh&amp;quot;), a few times (&amp;quot;hrm&amp;quot;), or a billion times (&amp;quot;hmmm&amp;quot;), but an &lt;em&gt;infinite number of times&lt;/em&gt;?&lt;/p&gt;&#xA;&lt;p&gt;Clearly, &lt;span class=&quot;math-container&quot;&gt;$Y$&lt;/span&gt; must have some special relationship to &lt;span class=&quot;math-container&quot;&gt;$f$&lt;/span&gt;? Some special &amp;quot;structure&amp;quot;? What he was talking about then, is that he was involved in a proof for the fact that there is some number &lt;span class=&quot;math-container&quot;&gt;$k \in \mathbb{N}$&lt;/span&gt; such that &lt;span class=&quot;math-container&quot;&gt;$Z \subset Y$&lt;/span&gt; is invariant under the &amp;quot;&lt;span class=&quot;math-container&quot;&gt;$k$&lt;/span&gt;th iterate&amp;quot; of &lt;span class=&quot;math-container&quot;&gt;$f$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$f^{(k)}$&lt;/span&gt; (i.e. &lt;span class=&quot;math-container&quot;&gt;$f$&lt;/span&gt; applied &lt;span class=&quot;math-container&quot;&gt;$k$&lt;/span&gt; times to &lt;span class=&quot;math-container&quot;&gt;$x$&lt;/span&gt;).&lt;/p&gt;&#xA;&lt;p&gt;Okay, so this is what I remember of what he told me. He had stayed behind very late talking to someone else, so I didn't want to take more than a few minutes of his time even though he was so kind, so I am left with questions:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Does what I remember (see above) make sense?&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;What does it mean to be &amp;quot;invariant under the &lt;span class=&quot;math-container&quot;&gt;$k$&lt;/span&gt;th iterate&amp;quot;?

I don't know if there is a consensus on what a good period of time might be, but it seems to be at least a few days.  With this in mind I wanted to ask the following two questions:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;1) Of questions that get answered on MSE, does anyone have data on how long it takes for 50%,60%,70%, etc. of questions to get answered? Or alternatively, how what percentage of questions get answered after 48 hours? 72 hours? 96 hours?  &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I confess that the above question is a bit leading and would require data from a site that is not MO. However, it's my opinion that a person should wait a week before cross posting. Admittedly this opinion is based on no evidence, and so having this data might help inform an opinion on that appropriate time to wait before cross-posting and better frame such a discussion. With this in mind I wanted to propose the following feature:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;2) Should MO add a feature that flags questions having phrases similar to &quot;cross-posted&quot;, &quot;MSE&quot;, or &quot;math.stackexchange&quot; ask the person posting to provide a link to the question? I suppose the feature could automatically check the time the question was posted on MSE and provide data on how long it usually takes to get an answer on MSE. In the absence of such data, perhaps this feature could just set a waiting period of at least $n$ days.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I realize that this agreement on the value of $n$ might be a contentious. However, I just saw a cross post where the waiting period was &lt;a href=&quot;https://mathoverflow.net/questions/182820/minimum-word-length-for-an-unusual-set-of-generators-of-the-symmetric-group&quot;&gt;7 hours&lt;/a&gt;.

But I can think of at least two arguments against the migration practice:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;the general SE guidelines for migration are that questions which are on-topic on the original site should not be migrated away; and&lt;/li&gt;&#xA;&lt;li&gt;removing more advanced, and IMHO generally more interesting and better composed, questions further decreases the overall quality of math.SE, and, if continued, may result in a situation where such questions are simply no longer asked there, effectively turning math.SE into undergrad-math-homework.SE (if it isn't already).&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;As an end-run around these two issues, I am wondering if it might be possible/acceptable to create an &quot;interesting (and unanswered) questions on math.SE&quot; thread here on meta.MO. The intent would be to advertise (unanswered) math.SE questions which may be of interest to members of the MO community, and ideally to have these questions answered on math.SE.&lt;/p&gt;&#xA;" OwnerUserId="13653" LastEditorUserId="13653" LastEditDate="2014-10-27T08:43:10.067" LastActivityDate="2014-10-28T22:14:01.610" Title="Creating a &quot;math.SE needs your help&quot; thread" Tags="|discussion|math-stackexchange|" AnswerCount="3" CommentCount="19" ContentLicense="CC BY-SA 3.0" />

Realistically I think the options for this are a bit limited. Two things come to my mind (aside from the well-intentioned suggestions made by the Masked Avenger). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The first is to construct a good and well-focused question that involves your idea, and (maybe) to add somewhere in the body that you would be open to a possible collaboration on this, giving suitable contact details. (Or, you could bring up the prospect of contacting someone offline in a follow-up comment, if they respond usefully.) It is quite true that MO has some success stories where collaborations began with an MO question, and I think the community might be sympathetic to this. But the emphasis here would be on the question itself, and I think it would also be good to be low-key about the possible collaboration. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(There is sometimes a funny dynamic about proposing collaborations, not unlike the dynamic seen on sites like match.com, or so I would guess. Indeed a mathematical collaboration is a type of interpersonal relationship with someone you might not know too well at first, and which involves a degree of give and take and some degree of commitment and so on. People often want to weigh all sorts of factors before &quot;taking the plunge&quot;. Same with how one chooses a PhD adviser, come to think of it...) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The other option, which I expect would be riskier in terms of the question staying open, is just to ask an advice-style question pertaining to the mathematical profession, which one sometimes sees on MO. You could maybe ask something very similar to what you ask here, or you could ask how other people in the profession broach the subject of initiating collaborations, etc. Such a question could be Community Wiki, and maybe such a direct approach would garner some useful suggestions. As I say it's &quot;riskier&quot;, but as my dad used to advise me, &quot;nothing ventured, nothing gained&quot;. Could be others are in a similar situation and would be interested in such a question. &lt;/p&gt;&#xA;" OwnerUserId="2926" LastActivityDate="2014-10-31T18:19:25.507" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

However, the amount becomes relevant in case of repeated bounties (same user, same question), then one has to at least double the amount of the previous bounty or put 500.

One of the reasons is that voting (for and against) political &amp;amp; philosophical issues, and in general--voting on &lt;strong&gt;opinions&lt;/strong&gt;, introduces to MO repressive censorship.

Closed questions with low score (including the answer score) are autodeleted quite quickly. To do this faster has some drawbacks. In particular, I do &lt;strong&gt;not&lt;/strong&gt; think that to &lt;strong&gt;have a flag &quot;off topic&quot; with similar functionality as &quot;spam&quot; and &quot;offensive&quot;&lt;/strong&gt; is needed or desirable. (The proposal seems to be about introducing this, not about improving it as the &quot;other&quot; flag is completely different in its effect.) &#xA;To use the &quot;other&quot; flag saying &quot;off-topic&quot; in such a case, seems a strange thing to do to me. This flag &lt;em&gt;only informs the moderators&lt;/em&gt; and is completely different from the two other flags. &#xA;If at all I would flag with saying what I want, namely that the question be deleted. However, I think this is a misuse of a moderators flag.

So maybe they want this, though, it still seems strange to me.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Below I give the details on the flagging dialog for open questions, as there is some confusion in the comments (note this is different for users that can vote).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Flagging for closure is done like this:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;click &quot;flag&quot;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;select &lt;strong&gt;&quot;it should be closed for another reason&quot;&lt;/strong&gt; &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;select the more specific reason, which includes &quot;off topic,&quot; but also &quot;too broad&quot;, &quot;primarily opinion based&quot;, &quot;unclear what you are asking&quot; and (again) &quot;duplicate&quot; &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;possibly some additional action, like choosing the sub-reason for &quot;off-topic&quot; &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;press &quot;flag question&quot;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;As Stefan Kohl mentions it is also possible to flag as &lt;strong&gt;&quot;very low quality&quot;&lt;/strong&gt; but this should not be done to a question that is written well but too simple to be on-topic; rather it is mainly to be used for posts that are &quot;very low quality&quot; for general reasons, like gibberish. (The consequences of this flag are somewhat different from the one mentioned above.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The flag &lt;strong&gt;&quot;other&quot;&lt;/strong&gt; plus explanation should not be used for signaling questions that are merely off-topic in a general way. This flag is the way to signal/communicate something to the site's moderator and should be used only if the matter requires the attention of a moderator specifically, that is when the general process of community moderation seems not capable of handling a particular matter. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;One could imagine to streamline the above process a bit (it might be this was the purpose of the request), via exposing off-topic in the initial list (as is done for duplicate) for instance, but then the initial list is already somewhat long, too, so it is not clear what is preferable. And, the process of actually voting to close is not much simpler either. I thus do not see an urgent need or even clear benefit for saving a couple of clicks at this point while making the initial list slightly less handy. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It should however be possible to have a bookmarklet that saves some clicks; &lt;a href=&quot;http://dropproxy.com/f/7FC&quot; rel=&quot;nofollow&quot;&gt;this exists for for votes to close (but I have not tried it)&lt;/a&gt;, it should also be possible to have it for flags to close.  &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorDisplayName="user9072" LastEditDate="2014-11-30T22:34:26.490" LastActivityDate="2014-11-30T22:34:26.490" CommentCount="11" ContentLicense="CC BY-SA 3.0" />

Showing that trisecting the angle was classically impossible, that hyperbolic and spherical geometry existed to refute the parallel postulate, and that certain theories were incomplete from being recursively enumerable instead of recursive, all these are small steps compared to the large ones of being able to find the language and ask the questions in that language.&#xA;Similarly, I would consider question-asking moments (Pacioli before probability, are certain constructions possible, Hilbert's list) to be at least as great an advance as the answers to these questions.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So I would ask the question: what would herald the next major advance in mathematics, be it a development of a certain theory, solving a set of conjectures, or laying the foundation for future work?

On the contrary, PhysicsOverflow certainly wants to maintain friendly relations with MathOverflow (&lt;a href=&quot;https://meta.mathoverflow.net/questions/1608/physicsoverflow-just-went-live&quot;&gt;and this is reciprocated too&lt;/a&gt;). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The purpose of importing posts, in fact is precisely the opposite of what it seems to be (mis)interpreted as in this thread. The purpose of importing posts, especially unanswered ones, is mainly to help the OP and others get an answer to their question. Even though MathOverflow is a much larger and more successful community than PhysicsOverflow, it is often the case that a question needs an answer from a physics point of view, and thus is equally or even sometimes better suited for answers on PhysicsOverflow. Thus, the post is imported (often through &lt;a href=&quot;http://physicsoverflow.org/4536&quot; rel=&quot;nofollow noreferrer&quot;&gt;this queue&lt;/a&gt;) and once it receives an answer, a link is posted below the MathOverflow question as a comment, to the answer on PhysicsOverflow.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Sometimes, even on answered questions, it's possible that the question can be answered from a more physics/physicist's point of view, which could make it also suitable on PhysicsOverflow. We only import questions closely related to physics, and for the purpose of trying to get them answers, to help both the MathOverflow and PhysicsOverflow communities.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As for the legality of the issue, since all MathOverflow user-generated content is licensed as CC-BY-SA 3.0, all legal criterion are met by the attributions below the posts. Regarding the unintentionally misleading nature of the &lt;a href=&quot;http://physicsoverflow.org/users&quot; rel=&quot;nofollow noreferrer&quot;&gt;users page&lt;/a&gt;, I have now added a short text at the top of the page. I hope it's better now.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Sincere apologies to the OP and others who were troubled by the lack of clarity. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Also, thanks to those who voiced their concerns regarding the import of accounts. We unfortunately cannot really &quot;remove&quot; all imported accounts as many would like to reclaim their accounts. However, those who would like their accounts deleted may write an email to admin [at] physicsoverflow⋅org or comment here (when writing so in the comments, I had expected the admin mailbox to be full of emails requesting account deletion - on the contrary, I was pleasantly surprised by a number of MathOverflow users asking for account reclamation).&lt;/p&gt;&#xA;" OwnerUserId="36148" LastEditorUserId="-1" LastEditDate="2017-03-17T10:13:04.480" LastActivityDate="2014-12-10T14:40:35.603" CommentCount="11" ContentLicense="CC BY-SA 3.0" />

However, I'd be unhappy if my user account were imported (fortunately it hasn't been), for some of the same reasons as discussed in the comments.  Here's a proposal for a solution.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The imported accounts do say &quot;This user is not yet participating on PhysicsOverflow, but we hope they will&quot; under &quot;Activity&quot;, which is honest.  However, it doesn't jump out at casual readers, and there are several other issues that could cause confusion if someone doesn't study the page carefully:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;The accounts prominently say &quot;Type: Registered user&quot;.  To me, saying someone is a registered user strongly suggests that they have chosen to register.  I suppose it's ambiguous, since technically one can register someone else without their permission or even knowledge, but it's misleading.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;They also list a time of first posting.  If one of my posts is copied to another site by someone else, I wouldn't describe it by saying I posted something there.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Even the heading &quot;User John Smith&quot; sounds like John Smith is a user of the site.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;In an ideal world, I'd recommend against having imported accounts at all, but I imagine that would require nontrivial software changes.  Another option would be to add more emphasis that the imported accounts are not real.  For example, by changing the heading from &quot;User John Smith&quot; to &quot;Imported content by John Smith&quot;, saying &quot;First posted: never [all posts were imported from other sites]&quot;, and changing the type to &quot;Type: placeholder for imported content&quot; or the like.

If your answer still provides some interesting progress towards answering the question, however, I would instead edit the answer to either remove or point out the mistake, and make it clear that your answer is not a complete answer to the question.  Another reason you might choose to not delete an incorrect answer is if your error actually shows that some reasonable proof strategy is doomed to failure, in which case (even if it doesn't directly help answer the question) it may be useful to others trying to answer the question or provide some general insight into the problem.

Rather, I feel, as Andy said, that they are trying to make use of &quot;the Pete L. Clark brand&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;More to the point, I just don't feel that things are being done in good faith.  The site currently says that I first posted three years ago.  Any way you slice it, that's simply untrue.  They also speak in terms of accounts being &quot;reclaimed&quot;, but come on: that's double-talk.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;After I wrote this answer, I spent more time searching the site, and I can't find any information whatsoever about who is running it.  The founders of the site have taken care to stay anonymous.  (&lt;b&gt;Added&lt;/b&gt;: More precisely, 2/3 of the founders are pseudonymous.  The non-pseudonymous founder is a minor.)  It seems that they want to be very careful about the use of their names and reputation.  The confluence of this and taking my name and using it to promote their site without even contacting me (hey, if you want me to join your site, how about asking me?) seems hypocritical and disrespectful.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;b&gt;Further Added&lt;/b&gt;: @Dimensio1no: &quot;the moderators and their names are accessible quite easily from the &quot;Special users&quot; tab under the &quot;Users&quot; page.&quot; Two of the three &quot;Super Administrators&quot; are listed only as &lt;strong&gt;Dilaton&lt;/strong&gt; and &lt;strong&gt;polarkernel&lt;/strong&gt;.  Those are not names of people.  In fact I received an email message from one of these, which said that s/he keeps anonymous for a &quot;good reason&quot;.  A serious academic site is one which is run by people who disclose their real names. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It also says&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;First posted (imported):   3 years&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;I have never posted anything on your site&lt;/strong&gt;.

Why did you put my name here in the first place?  If it is really only because I was listed as a user on another website: that's a problem.  I explicitly gave Stack Exchange permission to list me as a user on certain of their sites (and not on others).  Taking all the names on another company's site and importing them on your own site is not a good faith action.  Moreover you don't even inform the people that you are using their names in this way.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;What is the (full) name of your site's legal representative?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;b&gt;Yet Further Added&lt;/b&gt;:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As Mr. Abhimanyu has failed to identify anyone else by name as being owner and representative for the site, I will assume that he is responsible for it.  Let me respond to his points:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;1) Deleting all &quot;imported users&quot; who have not contributed and TP.SE user was a good start.  Thanks very much for that.  However, in that you are still claiming other users, the problem has not gone away.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;2) There seems to be some terminological confusion.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I said &quot;founder&quot;, not &quot;moderator&quot;.  Those are completely different things, and the fact that the difference is obscure both on the site itself and seems not to be not completely clear in Mr. Abhimanyu's mind is not a good sign.  &lt;a href=&quot;http://en.wikipedia.org/wiki/Stack_Exchange&quot; rel=&quot;nofollow&quot;&gt;Everyone knows&lt;/a&gt; that Stack Overflow and then Stack Exchange was founded by Jeff Atwood and Joel Spolsky. This openness and direct dealing with their clientele was certainly a key to their success.  I am kind of surprised that some people hear seem happy to support a site which is untransparent (and in my opinion, even somewhat misleading) about its own provenance.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;An &quot;imported user&quot; is still a &quot;user&quot;.  The language implies that they have &lt;strong&gt;used&lt;/strong&gt; the site.  Using this language and then correcting for it later on the &quot;user page&quot; (!!) is not complete clarity; it's double-talk.  Mr. Abhimanyu wrote&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;I do not wish to repeat how the fact that you do not use, contribute to, or endorse the site is the second-most clear thing on the page.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Even by your own admission, it is more prominent that you have a page with title and existence naming people as users of your site.  Whether the parenthetical (!!) sentence&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&quot;(This user is not yet participating on PhysicsOverflow, but we hope they will)&quot;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;is the &quot;second-most clear thing on the page&quot; is not a point I want to debate.  But the language is a far cry from saying &quot;This person does not use, contribute to, or endorse the site&quot;.  &lt;em&gt;Participation&lt;/em&gt; is something I never did on TP.SE, but I did sign in and create an account there.  The language of your site suggests that my account has somehow been transferred to PhysicsOverflow.  That's factually incorrect, it's legally questionable at best, and after all this conversation &lt;strong&gt;I still feel like you are exploiting people to promote your brand&lt;/strong&gt;.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;3) The claim that &quot;Pete L. Clark&quot; is licensed content under the Creative Commons is truly alarming.  Even with my &quot;account&quot; deleted on your site, I feel that I will have to consider responding to that legally.  Probably my first step would be to consult with an attorney at my university and have her correspond with PO's legal representative.

Let me elaborate the question a bit.&lt;/p&gt;&#xA;&lt;p&gt;My argument is that the statement &lt;span class=&quot;math-container&quot;&gt;$0{++}=1$&lt;/span&gt; of course can be taken as a definition of &lt;span class=&quot;math-container&quot;&gt;$1$&lt;/span&gt; but only when we have proved the following property of our intuitive natural number system, loosely speaking, &lt;span class=&quot;math-container&quot;&gt;$$\color{blue}{\text{There doesn't exist any natural number between $0$ and $1$.}}$$&lt;/span&gt;  The necessity for proving this statement is that without it we cannot say that the construction of our natural number from Peano Axioms is complete (note that Axiom of Induction only excludes the existence of any other &amp;quot;non-natural&amp;quot; elements but so far as I know, it doesn't trivially exclude the possibility of having natural number between &lt;span class=&quot;math-container&quot;&gt;$0$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$0{++}$&lt;/span&gt;). For if there really exists any natural number between &lt;span class=&quot;math-container&quot;&gt;$0$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$0{++}$&lt;/span&gt;, the resulting system doesn't (apparently) contradicts any one of the Peano Axioms but still clearly it isn't the natural number system that we have known since our childhood and which is our objective to treat formally. And since one of the most important objective of this axiomatic treatment of natural number is to formalize our notion of natural numbers, we mustn't include in our formalized system any property that contradicts out intuitive notion of natural numbers. Otherwise the whole point of construction becomes meaningless.&lt;/p&gt;&#xA;&lt;p&gt;Up untill now I can't find any rigorous proof of the fact that I have stated above and which, using logical operators becomes (all the variables indicating natural numbers), &lt;span class=&quot;math-container&quot;&gt;$$\not\exists b:0&amp;lt;b&amp;lt;0{++}$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;p&gt;Is there any proof of this result?

Elkies, respectively, seem like &quot;canonical&quot; respondents.  These tags are a reference to two  key-users,  something like an in-joke, part of MO-folklore, or something along these lines. Anyway,  they cannot be measured according to the usual standards of a tag; &lt;a href=&quot;https://mathoverflow.net/questions/tagged/20-questions&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;20-questions&amp;#39;&quot; rel=&quot;tag&quot;&gt;20-questions&lt;/a&gt; would be another tag in that category. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Tags for mathematics named after a certain mathematician. We have several of them. Over time we tried to make them &quot;specific&quot; by which I mean that different notions named after the same mathematician have different tags and/or the name of the tag is the notion not the person. There is still some work to be done in this direction, for example &lt;a href=&quot;https://mathoverflow.net/questions/tagged/gaussian&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;gaussian&amp;#39;&quot; rel=&quot;tag&quot;&gt;gaussian&lt;/a&gt; is still a bit unclear. Though it is at least not &quot;gauss.&quot;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Tags about (the work of) a mathematician. Some question about specific mathematicians are on-topic. In my mind there is  no reason a priori why there shouldn't be a tag &quot;erdos&quot; to tag questions about Erdős (or his contributions in a specific way). And the same goes for any mathematician about who (or whose work) there is a meaningful number of questions. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;To sum this up, I think we can have such name-tags if there is a need for a specific tag. Can you find, say, five questions about some given mathematician? If yes, I will not object if you tag them like this. (The &quot;you&quot; is an abstract you.) If no, the tag seems pointless. (Obviously there is nothing &quot;holy&quot; about five, but please let us say at least two, single used tags  get eventually auto-deleted.)  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, we should be careful as to still keep type 3 and type 2 above separate. This is an indirect reason I can see somewhat against these tags (and this is further motivation to try to keep their number somewhat under control via imposing that threshold above). It would not be a good idea to tag some general question about &lt;a href=&quot;https://mathoverflow.net/questions/tagged/euler-characteristics&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;euler-characteristics&amp;#39;&quot; rel=&quot;tag&quot;&gt;euler-characteristics&lt;/a&gt; as &lt;a href=&quot;https://mathoverflow.net/questions/tagged/euler&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;euler&amp;#39;&quot; rel=&quot;tag&quot;&gt;euler&lt;/a&gt; and possibly in addition &lt;a href=&quot;https://mathoverflow.net/questions/tagged/characteristic&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;characteristic&amp;#39;&quot; rel=&quot;tag&quot;&gt;characteristic&lt;/a&gt;.

(However, this action is as I say temporary: the action of the community members who voted for deletion should not be reversed without strong arguments.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I agree with the commenters who say they do not see how your post answers the question as asked. The problem statement asks whether one can &lt;strong&gt;prove&lt;/strong&gt; a statement of the form $\forall n \; \text{(under some conditions)}\; \exists D \in \mathbb{Z}[x] \ldots$. Giving an example (in a comment) about a special case $n = 2$ does not constitute a proof, and the body of the answer doesn't give a proof either: it seems only to give a (well-known) method for generating a set of solutions. But to give a proper answer, you have to give an argument which applies to all $n$, covering all the (infinitely many) cases. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It's my observation that many of the answers you give at MO do not go into such proofs at all, but rather exhibit sets of solutions to Diophantine problems in parametric form, which may or may not be the complete solution sets. Just to pluck one such example, there's this thread: &lt;a href=&quot;https://mathoverflow.net/questions/181242/does-the-diophantine-equation-x2ay2u2bv2-p2cq2-admit-a-complete/182363#182363&quot;&gt;Does the Diophantine equation $(x^2+ay^2)(u^2+bv^2) = p^2+cq^2$ admit a complete solution?&lt;/a&gt; Generally your posts seem to involve a series of algebraic or symbolic manipulations whose correctness is perhaps best tested using software which handles symbolic algebra, but in all the examples I've looked at, I've not seen a proof from you which is guaranteed to handle all possibilities. Meanwhile, the formulations of the questions make it clear that that's what is wanted and expected. Thus, your posts are often considered to be unsatisfactory according to the mathematical standards here. This is frustrating both to you and to others. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Joonas has asked about your professional relation to mathematics. Certainly your answers give (me, anyway) the strong impression of someone who is not a professional but someone who likes Diophantine equations or number theory as something of a hobby. Obviously there is nothing wrong with that, but the standards of proof at MathOverflow are very high, and it seems to be the opinion of many that such answers do not meet the standard. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;b&gt;Edit:&lt;/b&gt; The lock I placed has apparently been removed. To the best of my knowledge, only diamond moderators can remove a lock, but I can't tell who.

I don't want to discourage you by saying this, but I do want to encourage a realistic attitude. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I feel even more confident saying this since your two questions have been about category theory, the area in which I mostly work. As you know category theory has been worked over by hundreds of very smart people over a period of about 70 years and concerns extremely general structures of essentially algebraic type. The thing about such generality is that your question -- especially if it concerns basic concepts such as cartesian closed categories -- is with great probability either one where people know how to construct counterexamples (because, after all, with great generality comes great flexibility), or if not, it's probably true for some natural reason that people have hit upon after 70 years of collective effort. (It's different from how it is with say number theory, where the integers are what they are and there is less built-in flexibility, so to speak -- there one can hit upon some question that no one knows how to answer with somewhat greater probability.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Anyway, if you want to submit categorical questions to MO, you should definitely do a little research on them beforehand. Use Google, Wikipedia, the nLab, and of course MathOverflow and Mathematics StackExchange, just to name a few. If the structures you are asking about have been studied since the 60's -- and this is something you can probably find out through judicious use of Google -- the chances are high that answers have been around for a while. On the other hand, if you are talking about more esoteric matters such as differential cohomology in a cohesive $(\infty, 1)$-topos, then maybe not -- but there the bar is pretty high for knowing how even to formulate a sensible question. (I've seen some evidence of some young people overreaching in this respect, and it leaves a bad taste.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I suppose that people might assign greater cachet or prestige to MO than to Math.SE, but you should consider using both, and use your judgment which is likely to be more appropriate.

For example, it happens sometimes that strong mathematicians decide to post to MO for the first time, and your suggestion would not be a reasonable hoop to make them jump through. I'm not sure what mechanism you have in mind for the second question, but off hand I am skeptical. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I haven't tried to analyze the number of questions which seem to fall short of current MO standards of being on-topic. As a moderator responding to flags, I spend a disproportionate amount of my time on questions that arguably fall short of those standards, and yet my overall feeling is that most questions we're seeing these days are fine. I would welcome a more careful analysis however. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Your second paragraph raises a good point. There are questions that are in a kind of limbo of being easily answered but which no one feels moved to banish through a closure; my guess is that people who answer in comments might feel diffident both honoring an easy question (for them) and reaping points by picking low-hanging fruit by posting an answer. I know I sometimes feel that way. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A kind of stop-gap measure is to offer up a CW answer (and I do feel that is both appropriate and in good taste, for people who want to post an answer based on the ideas of others in comments). But in the end I agree that it is probably better to have the courage of one's convictions: if a question doesn't belong, say or do something to that effect, or if it does and you can give a strong answer, then do so in an actual answer box (in other words, don't be shy). I think many regular users do operate by that ethos already (in other words, I'm not sure we have a serious problem here). Meanwhile, as we encourage others to adopt that ethos, the CW option might not be bad for people who wish to whittle away at the unanswered queue. As always, I welcome comments on this idea. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;b&gt;Edit:&lt;/b&gt; Referring to the last paragraph, it would be in even better taste to ask a commenter if he/she would like to make their comment an answer, and create such an answer only if they reject the request or do not respond.

If you are not a mathematician yourself,&#xA;you should rather ask your question on &lt;a href=&quot;https://math.stackexchange.com/&quot;&gt;Math.SE&lt;/a&gt; instead -- unless a mathematician has&#xA;encouraged you to ask it here.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Apart from this, the main rules are the following:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;Questions should be brief, clear, self-contained, well-formulated and allow&#xA;well-defined, short (at most about 1-2 pages) answers.&#xA;Don't expect anyone to spend time on answering a question which is vague, overly long,&#xA;full of language mistakes, or which looks like it has taken you only 5 minutes to ask.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Questions which are or look like homework or contest problems are off-topic,&#xA;i.e. not welcome on this site.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;MathOverflow is not the right place to announce your results or to ask people to&#xA;check your proofs (&quot;Is my proof of the Riemann hypothesis / Goldbach conjecture / ... &#xA;correct?&quot; etc.); doing that anyway is likely to cause harsh reactions of the community.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Avoid asking questions which can easily be answered via a Google search.&#xA;In particular avoid duplicates, i.e. questions which have already been asked&#xA;before on this site.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If you know the answer to your question, then don't ask it here --&#xA;it would waste other people's time.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;To avoid duplicating efforts, ask a question either on &lt;a href=&quot;https://math.stackexchange.com/&quot;&gt;Math.SE&lt;/a&gt; or here,&#xA;but not on both sites. If you would like to have an exception from this rule&#xA;for a question which remained unanswered on Math.SE for a &lt;em&gt;long&lt;/em&gt; time,&#xA;enquire on &lt;a href=&quot;https://meta.mathoverflow.net/&quot;&gt;Meta&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Answering your question should not require reading particular books, papers etc..&#xA;This also means that questions about particular preprints are off-topic.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Questions which do not fulfil the above conditions usually get downvoted, closed and removed.&#xA;However note that as everywhere, it is accepted that respected members of the community &#xA;sometimes do not follow some of the rules.

In answer to (a), if the OP is offended or some other problem, the edit can be reverted or further revised.

During the beta phase, SE sites are still defining themselves and narrowing down what is on-topic/off-topic for the site. It's best for other SE sites to avoid interfering with this process.

Otherwise, the best thing to do is drop it.  If you extend the invitation, people who think you need the comment or answer will send it to you.  The main thing to gain from this experience is that this forum was the wrong one for your initial question/answer/comment, which is part of why it got deleted.

These are separate things. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Even if you did build a list of all sites and other SE questions that link to one of yours, it would not have enough information to determine when those links were followed, and thus could not answer your question of where a sudden flurry of recent views / votes came from.

I suppose if you went to headquarters and got one of the employees drunk enough they might be convinced to organize and share data with you.

For obvious reasons, questions liable to be deleted tend to attract more downvotes so the public data is noticeably different. Even so, there is an obvious increase in downvoting after the change in system.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Using the methods I used to look at the &lt;a href=&quot;http://blog.stackoverflow.com/2009/05/the-stack-overflow-trilogy/&quot;&gt;original trilogy&lt;/a&gt;, I don't see much evidence that people ask more or better questions when offered 10 reputation per upvote compared to just 5. However, there is strong evidence that people are more free with their downvotes on questions now that they don't cost reputation and more of those votes are allocated. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Your observation that you are less motivated by 5 reputation compared to 10 is interesting. Another pattern that MathOverflow users share with users on other sites is a clear tendency to &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/239688/question-post-ratio-by-post-sequence#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;shift from asking to answering questions&lt;/a&gt; as they gain experience. I'm not sure why that is, but I think it's a result of &lt;a href=&quot;https://meta.stackexchange.com/questions/42481/the-problem-with-extrinsic-motivation&quot;&gt;intrinsic motivations&lt;/a&gt;. Most people have a finite set of interesting and difficult questions that they've considered over their experience with a topic. When they find a Q&amp;amp;A site, they naturally are motivated to ask those questions. As they receive answers and run out of questions to ask, people naturally get excited about helping others with &lt;em&gt;their&lt;/em&gt; interesting and difficult questions. I suspect for many people the relative payout of questions to answers is not a large factor if it is a factor at all.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;http://www.beswick.info/psychres/management.htm&quot; rel=&quot;nofollow noreferrer&quot;&gt;Psychological research&lt;/a&gt; strongly suggests that people do better work when motivated by something inside of themselves (such as curiousity) than when they are motivated externally (such as by votes and reputation). Therefore we should expect that increasing the reputation payout will have no (or even negative) effects on average question quality.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Lastly, I agree with your philosophical point: good questions are worth more than good answers. However, you have to use the correct scale. As the asker, &lt;a href=&quot;https://philosophy.stackexchange.com/a/579/73&quot;&gt;an answer can be invaluable&lt;/a&gt;.

I hope this answer can help to provide some general precepts, so that such situations can be avoided or ameliorated. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;First, a few general points to keep in mind: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;ol&gt;&#xA;  &lt;li&gt;From the &lt;a href=&quot;https://meta.stackexchange.com/a/120577&quot;&gt;Stackexchange faq&lt;/a&gt;: If you are not comfortable with the idea of your contributions being collaboratively edited by other trusted users, MO might not be right for you.&lt;/li&gt;&#xA;  &lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;All within reason, of course. More on this in a moment. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;ol start=&quot;2&quot;&gt;&#xA;  &lt;li&gt;Editing is welcomed and encouraged. However, if an author of a post is resistant to edits, even reasonable ones based on generally accepted guidelines, be the bigger man or woman and &lt;em&gt;let them have it their way&lt;/em&gt;. &lt;/li&gt;&#xA;  &lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;The general aim is to clean up and improve posts over time, but in this case the reluctant author probably just needs more time to understand how things work around here. Of course you can gently remonstrate in a comment, but don't go on about it too long or be too insistent. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;ol start=&quot;3&quot;&gt;&#xA;  &lt;li&gt;We're supposed to be adults here. Try to resolve edit disputes through simple communication, without being rude to your fellow community members.&lt;/li&gt;&#xA;  &lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;As it says here: &lt;a href=&quot;https://stackoverflow.com/help/be-nice&quot;&gt;Be nice&lt;/a&gt;. Most of &quot;be nice&quot; follows from the golden rule, but one corollary that is particularly pertinent to editing is this: &lt;strong&gt;assume good intentions&lt;/strong&gt;. If you are annoyed by an edit, take a deep breath and remember that the editor is probably just trying to be helpful. Master your emotion, and don't get all touchy and defensive. Adopt the spirit of general cooperation to optimize our posts. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If simple polite communication doesn't work and you find yourselves at an impasse, you can flag for moderator attention to help resolve the dispute. &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;The following types of edits should be considered fairly uncontroversial: &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Fixing a misspelled name, as a basic courtesy to the name's owner. &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Correcting misspellings more generally is permissible I think, but I would consider it low priority, and you probably have better things to do with your time. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;On fixing grammatical errors: if the text is really unclear because of bad grammar, then yes. If the meaning is clear but the author's English is not perfect (according to you), then I'd be a &lt;em&gt;lot&lt;/em&gt; more circumspect. John Baez once said that &quot;broken English&quot; is the language of science, and we should be respectful of some variation. I often enjoy other people's written accents, as it were; I find they impart some of the charm to our little international community. (Thank you Yemon for your comment which prompted this.) &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;Clarification without changing the meaning. For example, to prevent closure of a question that might otherwise be okay, or adjusting the title if it describes the question poorly. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Fixing a minor slip (e.g., accidental insertion of the word 'no' where it was clearly not meant, etc.) where it doesn't require a full post to justify. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Adding related resources or links that will help someone answer the post, or that help provide context. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Editing of tags to more appropriate ones. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Adding in information found only in comments, so that one doesn't have to read through the comments to get the information. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Embedding or re-uploading images, fixing formatting, etc.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;This last point probably deserves some amplification. If someone has messed up the LaTeX or MathJax, for example forgetting a dollar sign, then by all means get in there. Potentially more contentious is where you're sure that you understand good LaTeX practice (for which there is a large body of literature) and you want to clean up what looks like amateur WYSIWYG-style formatting; it could be using $&amp;lt;$ for $\langle$ for instance, or spacing issues, etc. Well, proceed with fingers crossed, but if the author complains, refer to general point 2. above and back off. Even if you're sure you're right. (Take a moment also to reflect on point 2 below.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I'll throw in one more, as being part of the vision of the founders of the StackExchange sites, although my own attitude about it is somewhat soft: &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;It is permissible to remove &quot;fluff&quot; such as &quot;Hi&quot; or &quot;Thanks in advance&quot; or a signature in a question. &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;The founders would like SE sites to be more wiki-like and less a discussion forum. I can see the point of that, but I'll offer a personal comment below. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Here are some Don'ts: &lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Don't perform massive edits (e.g., a lengthy post that you think should be trimmed down) without prior discussion. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Don't self-indulge as a copy-editor. Examples might be: changing British spellings to American spellings, or enforcing consistency in &quot;house style&quot; (like thinking ZFC should be $\mathit{ZFC}$). &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;The point is that MO doesn't actually have an articulated house style as such, although there may be some general consensus on good LaTeX or MathJax practice, and those who have thought about such matters should be listened to respectfully. &lt;/p&gt;&#xA;&#xA;&lt;ol start=&quot;3&quot;&gt;&#xA;&lt;li&gt;Don't change the meaning of a question, or add your own question-extensions to a question, etc. &lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;Mainly these points can be summarized as: get your own ego out of the picture; don't be self-indulgent. Even though your icon may appear to announce your edit, the idea is to be quietly helpful: perform the edit discreetly and without fanfare. &lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="-1" LastEditDate="2017-05-23T12:37:20.967" LastActivityDate="2015-04-07T23:38:10.960" CommentCount="3" ContentLicense="CC BY-SA 3.0" />

Those things are better measured by voting. I'd be surprised if the moderator in question &quot;doesn't know anything about the subject&quot;, but that wouldn't really harm their ability to moderate this site. The decisions moderators make normally revolve around content that is clearly out of the bounds of according to site norms or resolving conflicts between users. Knowledge of mathematics can be helpful, but it's not critical as a rule.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;To make a guess about what brought this on, it looks like you've had some answers deleted. One of the principles of a Q&amp;amp;A site is that answers must directly address the questions asked. Your answers were deleted by a moderator as a result of 7 different flags by other users. It seems the consensus of the community is that that those answers don't answer the question itself.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;My suggestion for the future would be to carefully read the questions you are interested in answering and post answers that address the precise query the asker posed. &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Footnote:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;* Except on beta sites where they are appointed by Stack Exchange &lt;a href=&quot;https://meta.stackexchange.com/a/99341/1438&quot;&gt;Community Managers&lt;/a&gt;.

One of my earliest questions I used as a place to update with additional answers as I saw fit.  However, it got very long and hard to read.  I considered putting a large number of comments with references.  Eventually I decided that it would be best to update information off MathOverflow, and edit the original question occasionally when there was some news that belonged near the question.  At this point I have placed a header pointing to an Arxiv article, which article will be updated when there is more substance.  I may also place a link to an external site.  ( &lt;a href=&quot;https://mathoverflow.net/questions/37679/&quot;&gt;Erik Westzynthius&amp;#39;s cool upper bound argument: update?&lt;/a&gt; , if you want to see the clutter. )  Even if you decide to update just using comments, you can still produce clutter there quickly, making the update less likely to be read.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you do decide to update, I recommend making a personal webpage containing the information you wish to share, and updating that regularly.  Then provide a link to that webpage in the MathOverflow question.  This forestalls the potential clutter issue on the forum, and pushes it off onto the remote page.  If you make yourself custodian of the page, then you can provide whatever services you see fit, such as adding updates others make, or having a wiki for area-specific discussion.  If/when MathOverflow gets archived, they may decide to include some related appendices: do a good job, and your page may be one of them.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Gerhard &quot;I'll Go Work On Mine&quot; Paseman, 2015.05.23&lt;/p&gt;&#xA;" OwnerUserId="3206" LastEditorUserId="-1" LastEditDate="2017-04-13T12:58:28.650" LastActivityDate="2015-05-23T23:23:49.387" CommentCount="9" ContentLicense="CC BY-SA 3.0" />

As an example, before StackExchange and MathOverflow, the USENET newsgroups sci.math and sci.math.research were (in my view) the closest to providing anything like the services we get today.  Sci.math got overrun by spam, and moderation services on sci.math.research were small enough that (among other reasons) resources constrained it to have a small flow and user base.  Even the collection of mathematical newsgroups on USENET lacked the advantages the current platform has, the primary one being involved community moderation.

This time limit seems rather unreasonable, since (as in this particular case) it is easy/common to misread/misinterpret a question.  Is there a good reason to have only such a short window to reconsider a vote? or is it practical to increase the allowed time?  I feel like it does a disservice to the question asker to be unable to retract a downvote.&lt;/p&gt;&#xA;" OwnerUserId="35353" LastActivityDate="2015-06-04T15:23:56.843" Title="Time cutoff for changing vote" Tags="|feature-request|voting|" AnswerCount="1" CommentCount="3" ContentLicense="CC BY-SA 3.0" />

The question is about the correctness of a paper that has recently appeared in a peer-reviewed journal, purporting to settle a long-standing open problem regarding existence of a complex structure on the 6-dimensional sphere &lt;span class=&quot;math-container&quot;&gt;$S^6$&lt;/span&gt;.&lt;/p&gt;&#xA;&lt;p&gt;The basic question here is whether the community thinks this &lt;em&gt;type&lt;/em&gt; of question could be suitable for MO, but a subsidiary consideration is how to edit this particular question to remove at least some of the features that some commenters found objectionable. Namely, they found the question brusque and somewhat confrontational or less than respectful to the paper's author. Let me then take a crack at rewording the question:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;A paper purporting to solve a major open problem has recently appeared:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Gabor Etesi, Complex structure on the six dimensional sphere from a spontaneous symmetry breaking, Journ.

My question is whether these difficulties have been satisfactorily addressed in the current paper, and if so, whether this paper has indeed answered this outstanding question (whether a complex structure on &lt;span class=&quot;math-container&quot;&gt;$S^6$&lt;/span&gt; exists).&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;This rewording could perhaps be improved, but the idea would be to try and pinpoint the specific mathematical considerations within the body of the question, and do so in a more or less polite and decorous way.&lt;/p&gt;&#xA;&lt;p&gt;Onto the more general question: personally, I'm somewhat torn. We've generally declared to would-be solvers of the Riemann Hypothesis (etc.) that MathOverflow is not to be used as a vetting service, and that certainly seems like wise policy to me. Some users (I'll quote Joseph O'Rourke in his comment) take it a little further and say &amp;quot;It is inappropriate to discuss the flaws in a paper in a public forum.&amp;quot; Other commenters seem perplexed by this stance.&lt;/p&gt;&#xA;&lt;p&gt;I'd like to hear more discussion on this. I can definitely see that we do not want to be in the business of raking people over the coals, whether they be cranks or serious researchers. But if we manage to take the personal element out of it and get straight down to the business of pinpointing really specific mathematical difficulties encountered in peer-reviewed published papers, it's hard for me to think of really convincing counterarguments. Anyway, what do you think about this?&lt;/p&gt;&#xA;&lt;p&gt;Last I checked there are three votes to reopen, so maybe it's good to discuss this openly here.&lt;/p&gt;&#xA;&lt;p&gt;Oh, by the way: what about Community Wiki?

Is there a specific point that the asker is having trouble with (in which case details should be given, after which the question probably becomes suitable for MO)?

Freedom of speech, is perhaps a modern phrase for a little bit old value of Tolerance, or rather and outcome of tolerance, patience, and being wise. Let us remind that tolerance is not just tolerating someone who is against your point of view, and it could be aside someone who is trying to express his/her own point of view, but does not share the same language with you, or does not have the experience of yours in putting right words to his/her question.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For the people who have started discussion on MathOverFlow, let us remind that prior to this topologists used to send their questions to Don Davis's list, now called Topology Digest, along with other uses of that list, and they still do; that list was very useful in the sense it created a feeling of community among people. &#xA;It was  very exciting as all giants were there and though your question could be very elementary, you could ask question, and get a reply in private or public. &#xA;It could be someone got more interested in the question and gets in touch with the person who asked the question, and from personal experience I know that could lead to a years long lasting collaboration.&#xA;It could also happen that someone posted offensive notes, silly questions and so on. But, all of that was tolerated and handled perhaps in quiet. What it does teach us youngsters, is that by that tolerance shown by experts, you teach the youngsters how to treat people, how to tolerate and how to see good point among silly words, half-cooked ideas, so on. If someone was going to shout at that person saying that your question is off-topic or not a research question, that person perhaps was not going to ask more questions.&#xA;It could be that one is not using English as his/her native language. So, it appears that sometimes, well established mathematicians as above, ask questions, but since their English is not so perfect then they are put on hold. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Actually, if you look at the `put on hold' questions, you see some have put comment on them or answered them and sometimes a good load of discussion has started after that question. So, it implicitly, say that a silent majority is not in agreement with those few who feel they are in position to block people.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Let think of this. Imagine you were in Germany, in presence of Gauss, and you had the possibility of asking in German, knowing that you will be executed if someone there didn't like your question or your wording of question in German. Would you dare to ask, frankly?!?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, I propose this question, why always $1+(-1)=0$. Who is the right person to say this is a silly question?!.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One last point, I wonder how many of the people who block people, close, or put on hold, have a good experience of teaching?! I bet there are some points that you have used a book, 5 times, to teach or say 10 times, and a students asks a question and you see that there is a point you are not quite happy with your understanding. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The history of mathematics, and recent research is full of these stories, and someone has built a theory since they were not happy with a proof.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I invite all people here to more tolerance.

But of the form &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;{Site-name} is a question and answer site for {target audience}. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;In addition there is also the sites {on-topic}, which is  &quot;research level mathematics.&quot; These variables are used elsewhere too. So, to change that phrase would be first inconvenient and second it would nor fully solve the problem as the {target audience} is used elsewhere. For example &lt;a href=&quot;http://stackexchange.com/sites?view=list#oldest&quot;&gt;in this list of all sites&lt;/a&gt; Moreover see this old meta question and the comments there  &lt;a href=&quot;https://meta.mathoverflow.net/questions/458/what-should-the-hover-text-for-the-mathoverflow-link-on-all-se-sites-be&quot;&gt;What should the &amp;quot;hover text&amp;quot; for the MathOverflow link on all SE sites be?&lt;/a&gt; &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Community opinion&lt;/strong&gt; in the end was in favor of this phrase, even though many of those in favor still shared some of you misgivings.

In an academic context the word &quot;professional&quot; is perhaps not optimal, but it will be easier to comprehend than alternatives for many.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Target audience&lt;/strong&gt; does not mean that it is exclusively for this audience. The site is &lt;em&gt;for&lt;/em&gt; professional mathematicians, in the sense that it tries to satisfy the needs of this community.

There may also be some false positives where e.g. the image alt text contains an ImageShack URL, even though the actual image is hosted on imgur.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If the images still work, edit the post and reupload them to Stack Exchange's imgur account using the image upload button in the editor toolbar.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If they're already broken, try to recover them from the &lt;a href=&quot;http://web.archive.org/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Wayback Machine&lt;/a&gt; by prepending &lt;code&gt;http://web.archive.org/web/2/&lt;/code&gt; to the image URLs, and reupload the recovered images to stack.imgur.  (Please &lt;em&gt;don't&lt;/em&gt; just leave the image links pointing to archive.org; while this does generally work, we don't really want to rely on them or cause them extra server load.)  To make this easier, you may wish to install &lt;a href=&quot;https://gist.github.com/vyznev/9c0cca3109ddfbe043cc/raw/0d49cc5a38dafc1505014d3b3fc2e2b379fa3fbb/imageshack.user.js&quot; rel=&quot;nofollow noreferrer&quot;&gt;this user script&lt;/a&gt;, which automatically tries to reload ImageShack images from archive.org when you click them, and also highlights such images by graying them out and adding a red dashed border.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you can't recover the images, and the author of the post is still around, consider leaving them a polite comment to let them know that their post is broken, and asking them to reupload the images if they can.  If the author seems to be long gone, see if you can simply edit out the broken images without unduly damaging the post, or perhaps even try to recreate them yourself.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Finally, if the post really seems unrecoverable and useless without the images, you may wish to flag it or, if you can, just vote to delete it yourself.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;While you're editing the post, see if there's anything else (spelling, MathJax syntax, needless &quot;Hi!&quot; / &quot;Thanks in advance!&quot;, etc.) that you can easily fix at the same time.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Having edited the post, see if other posts in the same thread also have ImageShack images (the user script helps here too) and fix them as well.

What I mean are perhaps too vaguely described &amp;quot;solid graduate level questions&amp;quot; (not the most standard textbook-excercise question from some graduate Analysis or Algebra course but, quoting the FAQs emphasize mine, &amp;quot;the sorts of questions you come across when you're writing or &lt;em&gt;reading&lt;/em&gt; articles or &lt;em&gt;graduate level books&lt;/em&gt;&amp;quot;; in other words question that are a bit beyond what one can find in any book on the subject but questions that might come up when thinking beyond what one read).&lt;/p&gt;&#xA;&lt;p&gt;I believe that, ultimately, it is the smaller number of this type of questions that causes the at first glance paradoxical situation that on the one hand some people say that the level of MO significantly increased while at the same time I see some (at the strict/high-level end) users say that MO used to be better.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;As Neil Strickland remarked questions arising in the study of graduate level books are on-topic. Arguably, it also should not be forgotten that the site was founded by then graduate students.&lt;/p&gt;&#xA;&lt;p&gt;That being said the quality of a  question is not only determined by its difficulty. Furthermore, in my mind, the &lt;em&gt;level of a question&lt;/em&gt; is not only, and not even mainly, determined by its difficulty; for example, the context in which it is placed can be key to evaluate the quality of a question.&lt;/p&gt;&#xA;&lt;p&gt;Criteria  which I find relevant too include:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;clarity of presentation&lt;/li&gt;&#xA;&lt;li&gt;interestingness and relevance&lt;/li&gt;&#xA;&lt;li&gt;prior effort&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;For example:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;for a question to be at research-level I'd ideally expect that the presentation is in a form in which mathematics is usually written by working mathematicians (exception and accommodations can be made for users' having severe language-problems).&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;for a question to be at research-level I'd ideally expect that it is explained why the question is interesting and relevant to the asker. (&amp;quot;I was reading about subject S and this question Q that I find intriguing just occurred to me.&amp;quot; can be a valid explication.)&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;for a question to be at research-level I'd ideally expect that the asker made some prior effort to answer the question by themselves; e.g., the asker checked the Wikipedia page on the subject, as questions answered on the Wikipedia page on a subject usually should not be asked on MO.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Of course, the answer should not be too obvious either, but in my mind to place too much emphasis on the mere difficulty is not the way to go. There are plenty of worthwhile question that ultimately have a rather simple answer, while there are also plenty of questions that can be very difficult but still are pretty bad questions, as they might be cryptic, unmotivated, besides the point etc.&lt;/p&gt;&#xA;&lt;p&gt;Now, what does this mean, say, for exercises from a graduate level book or related questions. My advice would be to try to write a questions that does well on the criteria other than &amp;quot;difficulty&amp;quot; I mentioned.&lt;/p&gt;&#xA;&lt;p&gt;It is my impression that not few users have a serious distaste for question they perceive as &amp;quot;lazy.&amp;quot; Thus, something that is (or also just &lt;em&gt;looks like&lt;/em&gt;) a sloppily copied textbook exercise or homework problem can be faced with opposition, while the essentially same question embedded into a carefully crafted post giving some context and motivation might have done just fine.&lt;/p&gt;&#xA;&lt;p&gt;While one should not take this too far, I think it is fine that criteria other than the mere mathematical difficulty play a role in evaluating the suitability of a question; this is also common in other contexts, such as evaluations of manuscripts submitted for publication.&lt;/p&gt;&#xA;&lt;p&gt;Finally, it is also a goal of MO to provide a place where one can somewhat casually  learn about some mathematics in fields other than one's own, as a consequence of which a reasonable effort should be made that posts are accessible to a general mathematical audience (and not just a few experts in the respective subfield).&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;To sum this up:&lt;/strong&gt; I think we should be open to well-written and considerate questions at a solid graduate level.

So I would think twice about closing a question about Lorentzian geometry, even if it appeared elementary, compared to a question on Riemannian geometry, though I might not upvote it.

In deciding whether to close or not, I use a very high tolerance level for subjects not close to me (and avoid altogether some areas like geometry/topology, logic etc), and with a somewhat lower tolerance for areas where I trust my judgement (number theory, analysis, probability, combinatorics ...).  I also like questions to be well written and clearly posed, and if I cannot understand the question in an area I am familiar with, I am likely to vote to close as unclear.  I have noted a couple of differences between my reactions and some other users: when there is a clear math question that I find interesting, I do not feel any need for motivation spelt out in the question; on the other hand, I find myself more impatient than some others about vague questions, e.g. soft questions, or overly broad philosophical ones. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have reviewed more than my fair share of questions (900+ so far, putting me tenth on the list).  I can understand if people have concerns about a few people reviewing too many questions, and perhaps there is a meaningful discussion to be had on that topic.  For my part, I am happy to retract close votes if I think a bit more and have second thoughts, or if the OP edits and improves the question.  Sometimes I have been surprised to see what I think is a good question attracting close votes, and I usually leave a comment to try to persuade others to consider the question a bit more; on a few rare occasions, I have been disappointed that those voting to close did not reconsider their decisions.  I also feel that those voting to close have some responsibility to explain their views if the OP or someone else takes up the matter on Meta for example: in my meta answers, you'll find a few examples where I have tried to explain what I thought, and also a couple of examples where I proposed questions (sometimes ones that I had initially voted to close) for reopening after they had been improved.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Finally, I like the transparency of the system: anyone can find, from my profile page, all the questions that I reviewed (I think this works if I went through the review queue, and not directly from the questions page), and in any case for any closed question the identities of those who voted to close is public.

MathOverflow has enough curious people on it who like to choose what they read without hints from others they may have just met.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Long answer: There are ways.  Primarily though, it is about building a relationship.  If you establish a history of being interested in a person's work (and well-being, including giving them personal space), then you might ask if that person would look at something of yours or of someone else's.  However, the primary function of MathOverflow is to build a database for use by the community, not just for a set cadre of experts.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So use MathOverflow to craft relationships as well as make yourself attractive (in an intellectual sense) by posting your material and crafting it so that it is beneficial for the non-expert as well as the expert.

Let me highlight some things from a certain perspective.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;MathOverflow is a repository AND a community.  The idea is not just to get help, but to build a corpus of good questions and answers, so that readers of the future can find useful information more quickly.  Further, if online collaborations over small (in terms of writing) questions work well, they may result in larger collaborations on projects not suitable for a forum like MathOverflow where discussion takes a back seat to clarification and direct relevance.  With this in mind, I recommend the following:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;a) Pretend you are at an informal and otherwise professional seminar.  If you don't understand because (say) something is poorly worded or constructed, respectfully ask the speaker, but if you don't understand because you are new to the subject, ask someone outside the seminar where to start.  Think about what contribution your question or answer may make before submitting.  Oh, and wear pants and talk nice.  (Don't be a jerk at a seminar.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;b) Realize your contributions can be edited by others.  The basic intent of all edits should be to improve clarity and quality, and if everyone plays nice, people only improve on your stuff.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;c) If someone tells you that you are making a mistake, consider their point and whether they may be right.  Acknowledgment may not be necessary, but ignoring is done at one's peril of losing the privilege to be a community member, especially if a moderator is recommending a change.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;d) Ask for help, and do it the right way.  Usually help on math questions is for MathOverflow, and help for how to behave on/use MathOverflow or meta.mathoverflow is for meta.mathoverflow.net.  If you are confused, say so, and start on meta.  People here are often willing to help those who have read and are attempting to follow the rules.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;e) I did mention reading the guidelines before you post anything, right?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Gerhard &quot;Come And Play With Us!&quot; Paseman, 2015.09.19&lt;/p&gt;&#xA;" OwnerUserId="3206" LastActivityDate="2015-09-19T18:29:12.770" CommentCount="3" ContentLicense="CC BY-SA 3.0" />

So at the moment I don't see evidence of downvoting that looks 'vindictive'. I realize that unexplained downvotes are an annoyance, and particularly if several happen during a short time frame they might look suspicious, but the system is so far not showing us that, and they could be from several different users who ('childishly' or not) might be reacting to a certain amount of noise they are hearing -- it's impossible to say. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As to what can be done: as quid suggested, alert the moderator team and tell them what you know or suspect, either by raising a flag or writing directly to moderators@mathoverflow.net. Where you suspect revenge downvoting, you can mention time frames or suspected users; the moderators can then take a closer look. The Stack Exchange Community Team (team@stackexchange.com) can also have a look. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Targeted voting (either up or down), meaning voting not based on the merits or demerits of a post, is a site violation that moderators and SE Community Managers take seriously. You should always report such instances, as you suspect and as they arise. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are other points of concern raised by your post. You mentioned your deleting questions. As I believe you know, the system design prohibits users from deleting questions that have either (1) an upvoted answer, (2) multiple answers (upvoted or not), or (3) an accepted answer; this is explained here: &lt;a href=&quot;https://meta.stackexchange.com/questions/5221/how-does-deleting-work-what-can-cause-a-post-to-be-deleted-and-what-does-that&quot;&gt;How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion?&lt;/a&gt;. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Perhaps what you meant is that, where one of (1)-(3) applies, you have &lt;em&gt;heavily edited&lt;/em&gt; a question to the point where it became &lt;em&gt;virtually deleted&lt;/em&gt;, as happened earlier here: &lt;a href=&quot;https://mathoverflow.net/questions/219869/intuition-behind-salient-numbers-in-number-of-h-cobordism-classes-of-smooth-homo&quot;&gt;Intuition behind salient numbers in number of h-cobordism classes of smooth homotopy n-spheres&lt;/a&gt; This should not be done; in fact it's a site violation, as has been explained elsewhere. If there is a really good reason that a question (under those circumstances) needs to be deleted, this should be made clear to moderators at the site or system level through private message (via flag or email). On the other hand, if it is merely a situation where you are for some reason unhappy with the Community response to your question, then no, we moderators generally won't enable a question deletion or virtual deletion. Conflicts have to be resolved in a different way. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;We are here to help if we can. In situations where an argument is going on in a comment thread (as at the aforementioned MO post), moderators seek to lower the noise level and bring the discussion back to the mathematics, which is what everyone should want. It is true that where there is sniping back and forth and flags are raised citing rudeness/offensiveness, I will go in and either delete comments if I judge they are adding nothing useful to the discussion, or if part of the comment is making a mathematical point, then I typically prune out non-constructive content but do what I can to leave the mathematical content intact. I try to be fair in doing so, but it's often difficult and unpleasant work, made more difficult when some users embed their mathematical points in rather blunt phrases (I can see this with some of your interlocutors). I also know full well that there are users who are going to protest loudly or cry 'censorship' every time I perform any edit at all in this capacity, which I do as part of my 'job' obligations but often with heavy heart. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;To conclude, I am sad to see the threads after your posts degenerate into arguments and to see how unhappy certain community responses make you. I suggest that &lt;em&gt;all&lt;/em&gt; participants get into a mindset of problem-solving and conflict resolution, de-escalate emotions, be considerate of others, bring a sense of humor and open-mindedness, and take a little break now and then to cool off if need be. Keep the focus on the math. Be the bigger man or woman and don't let yourself get rattled publicly.

I do commiserate with you on the difficulties of being a moderator, though you did seek the position and were aware of the heavy, concomitant responsibilities.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I've frequently deleted my own questions and answers (and comments when no longer useful) in the past that have received no repsonses except perhaps upvotes or downvotes, especially when I've found a satisfactory answer myself and even more so if the answer is quite long and involved and would be better proferred in a note at my website/mini-arXiv to those who might be interested--notes that can be embellished and revised with new info without annoying the disinterested. Seems natural enough.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I reported two questions (Stasheff polytopes, Cavaliri's principle) to moderators that are quite old and have had no activity in months, but were downvoted within seconds of each other yesterday--a third very old question (an intriguing tapestry), the day before.

I do not want to mention any suspected violators since such 'gossip' would also cast aspersions on the more or less innocent, which is unacceptable to me.

Then received the intended effect of Ryan's initial opinionated comment (bereft of additional mathematical content since the cited OEIS ref contains the correct relation to differential manifolds in the first comment there, so that seems only an entry point for his objective of politiking)--a downvote--and responded accordingly. As in &quot;Why do the Bernoullis arise everywhere?&quot;, Ryan seems prone to denigrating posts according to his own personal tastes (which does seem to coincide with a coterie of similarly opinionated users, hopefully a minority, but a demonstrative one that tends to politik against questions, not suiting in format and/or content their tastes, with opinionated comments at best tangential to the math and veiled as constructive criticism). After an expected lively exchange, censorhip led me to delete any remaining comments, edited or not, to avoid a misrepresentation of my thoughts. I'd prefer to move the bulk of my question to my website where I can then allude to relevant ideas in OEIS entries without airing any dirty laundry or indeed non-productive question at MO, i.e., clean up in almost a literal sense for which I have received the disciplined and peer pressure badges, so such behavior is condoned by the exchange. The only obstacle is the one answer to my question, so I haven't deleted the question, but have deleted the text that unproductively addressed the comments and really is unnecessary. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Finally, I'd like to ask why there has NOT been more DOWNvoting on this meta question.

This is not very common on MO, though, and some might not like their comments being deleted (not me though). More generally, the theory the designers of the site have regarding comments is that they are mostly temporary notes and not part of the main content of the site, which is in the the posts (questions and answers). Of course, also on other sites not each comment is really temporary but the fact that it is intended like this informs the design. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Even if MO does not completely follow this model, it still runs on a design based on the idea that  comments are not a place for permanently relevant information.

It is also in some old FAQs, IIRC. It seems it worked reasonably well. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In view of a comment let me add that I am not sure it makes sense to write down some suspension policy. Cases are individual and need to be handled on an individual basis. To fix some rules in abstract seems designed to lead to problems, and endless discussions. It seems reasonable to me not to be very restrained when facing users that seem to try to use the site in bad faith. Whether they do so under the auto-generated name, a pseudonym, their real-name; or a &quot;real name.&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The comment of Mad Scientist is in my opinion spot-on. Mainly, moderator action should be taken against behavior, not based on some secondary criteria. Indeed, doing the latter creates the separate issue that users try to work around it, and in doing so do things that might well be considered quite more problematic than anonymously asking a question on this site (even when in doing so they evade a ban).&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Should we ban any users that use anonymizing tools to hide their identity? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Assuming you mean TOR and alike. Some users, not me, might have a need to use such technology that has nothing to do with trying to misbehave on MO. See for example &lt;a href=&quot;https://meta.mathoverflow.net/questions/1746/javascript-loading-problem&quot;&gt;this request of a real-name user&lt;/a&gt;. I do not think to just ban this on principle is a good idea. &#xA;It could be consider as a factor in moderation decisions though.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Should we require using real names? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Correct me if I am wrong but as far as I know and recall several (not to say most) of the bigger problems were actually caused by users under their real-name (or at least under what I took to be their real name, see below) or latter additional accounts that were, to those in the know, linkable to real-names. Thus, I do not quite understand what should be achieved by this.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Indeed, one might go as far as speculating that the real-names in the end had a negative effect. Users had to dig themselves in rather than to have the option to just walk away and perhaps come back in good. &#xA;Or, they pulled off stunts to get around the real-names encouragement policy.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;On a practical note:  there are masses of users in the network that might create an account with one click. Most of them will  not be aware of such a  policy. Would you intend to follow up on each such instance or delete on-sight? This will cause a lot of work and friction. Or, there would be a need for a technical solution. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Basically, I think one would have to change the sign-up drastically. However, then real names as &lt;em&gt;display&lt;/em&gt; names would (still) not really be needed either. In fact it would be less needed then. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Should we maintain the status quo? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Yes, mainly. What annoys me personally are  &quot;fake real-names.&quot;  Users should either use their real-name or something easily identifiable as not a real-name. If such &quot;fake real names&quot; would be discouraged or essentially banned it would have my support. (And I'd yet have to hear an argument in favor of them. There existence might also be encourage by the existing real names policy, one more point against it.) I know there might be some corner-case, where this might cause some issue, but by and large this should be reasonable to maintain. One might also make exceptions for common given names. But something that quite definitely looks designed to be read as a given-name name combo should be real or better avoided. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Are there other things MO could do to encourage civil and responsible behavior for all users?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;You could moderate more tightly. I do not mean bans or moderator messages. Just delete comments that seem a bit rude or even just snarky (there is no need to make much ado about it, they will just be gone). On other SE sites moderation is a bit stricter. They have no real-names policy but are rather more civil (well some of them, some of the time, and I do not mean the one I moderate, which in any case is too small to be representative for anything).   &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Finally, I think one should resist the temptation to try to install policies one cannot enforce. It can back-fire. Some months ago (maybe longer) a user in a meta-post was quite explicit about this. They got banned &lt;em&gt;permanently,&lt;/em&gt; and they try to evade the ban, and basically they have nothing to lose. While I do support that ban (even actively at times) and that user did things &lt;em&gt;completely&lt;/em&gt; out of line, it still shows a problem with permanent bans.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Personally, I feel that at times moderation on this site is too emotional. At first, little is done since we are all a big community and one does not  want to be seen as being oppressive or censoring.  Then, things go too far, and many lose their patience and relatively massive actions are taken.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I believe sometimes it would be good issues would be escalated earlier but slower. The site has quite clear rules regarding content and conduct. They should be enforced on a daily basis, even if at times only by a stern comment. &lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorUserId="-1" LastEditorDisplayName="user9072" LastEditDate="2017-03-17T10:13:04.480" LastActivityDate="2015-11-17T11:58:26.707" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

The discussion of whether to have anonymous usernames is not new, and some arguments for them are repeated here.  The anonymity policy should also address the issue of registering to use the site.  Below I advocate a policy of non-anonymous registration, as well as adjust how problematic registrants are treated.  I do not say to remove bans; that is a part of the administrators toolkit.  I do say that community treatment as well as moderator treatment of such registrants should change.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;To address some of quid's concerns raised in comments: I recommend non-anonymous registration to increase accountability.  The vitally private registration information (real name, real contact, real endorsers, other real info) does not need to be made available to anyone but the top level adminstrators, and should not be needed except as used to hold registrants accountable.  This ideally is limited to behaviour moderation and control on the forum network, but can extend to real-life reputation, as such information could be used in legal or civil or public actions against the registrant.  Play nice, don't screw up too much, and noone ever needs to look at the record.  Do something for which you need to answer to the moderators and or forum community, then the guardians have something to use.  When I ran an internet access company, we needed and guarded such records for adminstration and accountability purposes.  If the dogs are attacking, the Internet dogcatchers need to know where the dogs are.  You want examples quid?  Ask the moderators; I don't have the information and prefer not to speculate in this thread. Also, I don't need to know your real name or have the moderators treat you and me with seriously different policies. I need, you need, the community and the health of this forum need the moderators to know how to hold me, you, and the community members accountable.  Anonymous registration works against this. &lt;strong&gt;End Edit 2015.11.17&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It may be time for a two- or multi-track system, which is a little more elaborate than suspend/unsuspend/ban.  For simplicity, I describe a two-track system and let the social engineers generalize it.  Suppose there is an identification system (not necessarily Open-Id, say AMS membership for example, or an endorsement from an existing forum member in good standing) which allows one to register for participation in the forum.  Then such a validated person is on the first track, can open multiple accounts, and participate with real or fake names as wanted, within restrictions to reduce harm that might be caused.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There is no need for a second track until misbehaviour is identified, warned, and gone uncorrected.  Then the second track kicks in, and the appearance and other properties of the accounts change.  Primarily, reputation gets harder to earn for these accounts ( and may be reset to zero ), and all posts from this person appear in a yellow background.  Only model behaviour and exceptional circumstances can take a person off the second track back on to the first, and the system is designed so as to discourage posts from this person while on the second track.  This is different from banning because every contribution the person chooses to make is a signal to themselves and the community that they are on the second track, and are working their way back to the first track; banning or suspending just prevents them from making positive or negative contributions.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It may be time to abandon the ideal of &quot;let everybody have a chance to post&quot;, and move towards allowing only those who have shown some ability to mesh with the community to allow to post on MathOverflow.  Having them register with and participate well on other forums first may allow them easier entry into a specialized forum like the one this community has built.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(I am suspending signatures on this thread until such time as a relaxed and welcoming atmosphere can be restored.

Having spent 5 years on these, I can vouch for all three, although this has not always been this way (I remember not only me being mistrustful towards SE a while before the SEification of MO, back when Jeff Atwood was moderating). Should a newcomer who has just learnt about MO and sees a question they can answer have this trust right away? One of the things that made MO work so well is the ease of joining, and too high expectations on the user's confidence in MO will undermine this ease.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;There are people who do not want to be associated with controversy in discussions, &lt;em&gt;even if they do not themselves actively take part in this controversy&lt;/em&gt;. You are forcing them to attach their names to discussions they cannot control. I remember one MO member threatening with leaving MO due to being accused of sexism in a comment thread on the grounds that a future employer might see the debate and file away their application as &quot;possibly controversial&quot; without bothering to check who was in the wrong. (I hope I did not misrepresent the argumentation.) While each of us has their own opinion on this sort of hiring practice, I think a number of people shares this kind of reservation, and MO will be off for the worse if they are kept out of participating.

At a maximal length of 150 characters they can be relatively long and it is encouraged to write informative titles. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A way to achieve this can be to reuse the main question of the post, or a modification thereof, as the title. Indeed, there is a recommendation to make your question your title in the general guidelines on asking.

These two parameters (i.e attraction and information) are what I personally pay great attention to while choosing a title for my posts not really the capitalization of the words.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you know how to use the keywords in your title, you will have no problem for &lt;em&gt;coding enough information in short attractive phrases&lt;/em&gt; in both question and non-question styles. Correct capitalization can help in this direction. However it is a bit marginal with respect to choosing the right words for the title.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The main point is that your title is &lt;em&gt;a kind of abstract for your question&lt;/em&gt;. While too short and generic titles are not that informative, too long ones are also not attractive and a bit hard to read and grasp in the first glimpse. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Anyway you should think and find the appropriate style and the optimum length for any of your questions to maximize the information and attraction in the title no matter whether it is written in a question or non-question style. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;For example there could be two alternative ways for titling &lt;a href=&quot;https://mathoverflow.net/questions/23478/examples-of-common-false-beliefs-in-mathematics&quot;&gt;this question&lt;/a&gt;. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;1- &lt;em&gt;Examples of Common False Beliefs in Mathematics&lt;/em&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;2- &lt;em&gt;What are examples of common false beliefs in mathematics?&lt;/em&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Both of them seem attractive and informative enough to me to make me curious to open the post and look inside. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Moreover let me add the point that apparently there is &lt;em&gt;no unique&lt;/em&gt; way of capitalizing the titles in English grammar. See &lt;em&gt;Rule 16.a&lt;/em&gt; and &lt;em&gt;Rule 16.b&lt;/em&gt; in &lt;a href=&quot;http://www.grammarbook.com/punctuation/capital.asp&quot; rel=&quot;nofollow noreferrer&quot;&gt;this source&lt;/a&gt;. You can follow more precise descriptions in standard style books, if you want a pedantically comprehensive answer. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Though, I personally very much doubt that such level of attention to the pedantic points in English writing should be a typical MO user's priority when adding posts here, particularly when most of them (like me) are non-native English speakers who need to focus on improving their more essential linguistic abilities like expanding the domain of their vocabulary or mastering in daily used grammar to soften their fairly mechanical English. &lt;/p&gt;&#xA;" OwnerDisplayName="user82843" LastEditorUserId="-1" LastEditorDisplayName="user82843" LastEditDate="2017-04-13T12:58:28.650" LastActivityDate="2015-11-29T18:31:16.683" CommentCount="6" ContentLicense="CC BY-SA 3.0" />

Its purpose is to highlight some meta-question that seem particularly relevant in the long run; for short-term visibility there is a another tag &lt;a href=&quot;/questions/tagged/featured&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;featured&amp;#39;&quot; rel=&quot;tag&quot;&gt;featured&lt;/a&gt;. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;These question can be &quot;frequently asked&quot; in a literal sense, but many also contain  information that just seems relevant to users or the site as a whole (see the list below to get an idea). They provide a natural extension of the Help Center, which is more static and in large parts not  editable  on a per-site basis. They also allow the community to be more directly involved in creating and curating the documentation of a site, which is particularly relevant for questions concerning policy and etiquette. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;How can a question be tagged &lt;a href=&quot;/questions/tagged/faq&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;faq&amp;#39;&quot; rel=&quot;tag&quot;&gt;faq&lt;/a&gt;?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As mentioned at the start, the tag is a moderator-only tag, and it is this expected that  users  cannot directly apply it. A way to go about getting a question tagged as &lt;a href=&quot;/questions/tagged/faq&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;faq&amp;#39;&quot; rel=&quot;tag&quot;&gt;faq&lt;/a&gt; is to apply the tag &lt;a href=&quot;/questions/tagged/faq-proposed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;faq-proposed&amp;#39;&quot; rel=&quot;tag&quot;&gt;faq-proposed&lt;/a&gt;. The proposal can then be reviewed by the community and the moderators. There is no hard and fast rule which questions should be tagged as &lt;a href=&quot;/questions/tagged/faq&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;faq&amp;#39;&quot; rel=&quot;tag&quot;&gt;faq&lt;/a&gt;. The existing list can provided some guidance.

But usually this will involve some effort by the OP to improve the question (improve the clarity, provide context and/or motivation, link to relevant sources, etc.), and if you strongly believe that your question is on-topic for this site (a site which serves professional mathematicians and their graduate students), then you should probably put in such effort. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Users make their best judgment as to what is on-topic for this site (e.g., what is &quot;research-level&quot;), but on occasion the judgments may be based on impressions or intuitions as opposed to deep engagement with the subject matter. If however the OP makes an effort to formulate a question with a professional appearance, and is willing to engage with users who state their criticisms, the more superficial reasons for closure will likely not be valid.

A &lt;em&gt;polyhedron&lt;/em&gt; is defined as a solid whose boundary consists of a finite number of polygons. Polygons are apparently to be understood to mean convex polygonal plane regions here. Admittedly, I have changed this definition by eliminating the connectedness requirement and requiring the solid to be bounded. If there is to be any hope of the definition becoming equivalent to (1), these changes are necessary in order to exclude from consideration, for instance, the exterior of a tetrahedron or an infinite trihedral region, in which case the &quot;polygons&quot; bounding it are themselves unbounded.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;What I am really interested in is any equivalence of (1) with a definition in the spirit of (2).&lt;/p&gt;&#xA;" OwnerUserId="85583" LastEditorUserId="-1" LastEditDate="2017-04-13T12:19:34.473" LastActivityDate="2016-01-24T21:01:30.193" Title="Can I ask this question here?"

Is it appropriate to get an opinion from the MathOverflow community on specific research statement S?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I provide a couple of examples below to give an idea of specificity.  I would also welcome examples from others as to how to frame such questions, as well as reasons why MathOverflow is not a good place for this.  (I think it is a good place though.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Example 1:  In the spirit of Gowers's FUNC project, I decide to build a lattice of lattices: for each union closed family F on a base set of n-elements, I look at it in the collection of the subset of 2^(2^n) of union closed sets, and make a lattice L out of the collection (not necessarily a sub lattice of 2^(2^n) ). While my motivation is to search for counterexamples inside L, it may be that L itself will yield a counterexample for n large enough.  Regardless of the motivation, what interesting questions can I find to ask about L?  Would asking if L were modular be important?  Can I make a good research question from it?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Example 2: Hearing people talk about the Collatz function turns me off; I will talk about the Syracuse problem instead.  Suppose I want to consider dynamics of the problem over the Gaussian integers, where I introduce specific variant G of the Syracuse problem over Z[i].  Is this reasonable, or should I instead consider related problems over a class of algebraic structures?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Note that while many questions on MathOverflow have statements S and ask for references about S or proofs or refutations of S, or even relations of S to other statements T, the two examples above are a different type altogether.  Although proofs, references, and related information about S are welcome, what is really desired are two things: an assessment of S as a worthy topic of study, and a family SS of related statements which might aid in the study of S or are preferred over S to be studied &lt;strong&gt;and of interest to some significant part of the professional mathematical community&lt;/strong&gt;.  Just as important, answering the question should not take much effort.  If it is old hat, then a reference showing where it has been done is all that is needed.  If it is poorly organized, there should be a quickly explainable reason.  If it is of interest (and the reasons for not sharing don't apply), why not share it?  If there is something easy that can be done to improve it, mention that in an answer.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Motivation: I recently asserted privately that a certain statement S would be worthy of proof/refutation, and am having second thoughts.  It would be nice to get professional advice about lines of study.  It would be too domain specific to ask about S on academia.stackexchange.com, and math.stackexchange.com also strikes me as the wrong forum.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Gerhard &quot;Can We Crowdsource Graduate Advising?&quot; Paseman, 2016.01.26&lt;/p&gt;&#xA;" OwnerUserId="3402" LastActivityDate="2016-01-27T00:17:09.077" Title="Is this (&quot;Is this a good research question?&quot;) a good MathOverflow question?"

So, it seems to me that any other consideration about the length of a title is arbitrary and shouldn't be used as a justification for editing a post insofar as a title provides sensible information that would be lost by making it shorter. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;2) The new title by Myshkin is certainly shorter than the old one. Yet, it's also less precise and more confusing, and I'm not convinced that shortness is more valuable than clarity. In my limited experience, &lt;em&gt;algebraic&lt;/em&gt; number theorists assume the terms &quot;natural density&quot; and &quot;Dirichlet density&quot; refer, by default, to the quantities that I'm considering in my question, and that's probably why Myshkin has thought the old title contained some redundancy. However, that's not the case with &lt;em&gt;analytic&lt;/em&gt; or &lt;em&gt;combinatorial&lt;/em&gt; number theory, which is the origin of much confusion and the explanation for the parenthesis &quot;(relative to the primes)&quot; I had put in the old title.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So I'm writing here to ask if there is a policy on MO to deal with this kind of &quot;issues&quot;.

Since the tags already convey the general subject area of your question, the title should communicate the question itself as faithfully as possible. If necessary, leave out hypotheses in the title, and in the body of the question, explain why the question requires those hypotheses.&lt;/p&gt;&#xA;&lt;p&gt;Don't be afraid to make your question title long. Titles are allowed to be anywhere from 15 to 250 characters long. 140 characters (the length of a tweet) takes up about two full lines on the home page, so try to keep it less than that. But 140 characters is a lot longer than you might think. Too many people restrict themselves to 20 character titles. They're trying not to waste your time by making you read a long title, but they end up wasting more of your time because you have to actually open the question to see if it's interesting to you.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I would summarize this as informative titles are strongly encouraged; but do not over do it. (Note: it seems the 250 characters is not [anymore?] true; the limit is 150.)&lt;/p&gt;&#xA;&lt;p&gt;There is also a post on &lt;a href=&quot;https://meta.mathoverflow.net/questions/2208/editing-etiquette&quot;&gt;Editing etiquette&lt;/a&gt; in general, which I would paraphrase very roughly as saying editing is fine and encouraged, and everybody should try to see the glass as half full rather than half empty.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;How does this relate to the specific situation?&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;I think your original title was a good one with the possible exception of the &amp;quot;Ref. request:&amp;quot; at the start.

(Your most common tag was nt.number-theory so this does not directly apply, but would you have asked about a result in ac.commutative-algebra instead it would.)&lt;/p&gt;&#xA;&lt;p&gt;The parenthetical that got removed: my fist impulse would be that this is maybe too verbose for a title, but on second thought it happens not rarely (in any case it happened to me and I believe I observed it sometimes) that users are set on a track by what they see first (in the title) and then answer based on this even if the body explicitly over-rides it. In that sense, I think you have a point that it is of value to have it there.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;tl;dr&lt;/strong&gt; Your title was fine, with the possible exception of the quasi-tag &amp;quot;Ref. request:&amp;quot; and I can understand the editor, too.

I think this question is an opportunity for more mathematically informative answers to be given by people who are familiar with numerical GR and the LIGO project in particular.  For example, I have heard from practitioners that there have been substantial advances in numerical GR in the 21st century that draw on nontrivial theoretical mathematics, and I would be interested to know in more detail what those advances are and to what extent they have helped with the extraction of the relevant figures.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Finally, I think the observation of gravitational waves is an incredibly important scientific discovery, and this question in particular is an on-topic forum for illuminating intersections with research mathematics.&lt;/p&gt;&#xA;" OwnerUserId="121" LastActivityDate="2016-02-14T13:57:31.373" CommentCount="25" ContentLicense="CC BY-SA 3.0" />

In situations where reasonable people can disagree, this seems a perfectly fine way to resolve the disagreement -- one may be unhappy with the community decision, but one can still accept it with good grace (as I will if the question under discussion is closed again).  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A similar question (in terms of suitability for the site, not to me in terms of interest) came up not so long back &lt;a href=&quot;https://mathoverflow.net/questions/172109/optical-methods-for-number-theory&quot;&gt;Optical methods for number theory?&lt;/a&gt; where I found myself on the other side.

In that case, it was argued in Meta that the question could be salvaged and reopened, which is what happened.

A secondary reason is that there seems to be a lot of incidental information that does not seem to support the main specific question I think you want to ask.

I am trying to define and study certain characteristics of these patterns, and my main questions are : what references cover material like what is presented below, and what search terms/synonyms can I use in doing more research into these structures and these particular characteristics? &quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now I am not sure that I understand the characteristics through your examples and presentation, so it might help to give examples that represent a scale for each parameter.  Say 5 examples of increasing D value, with some words on why it is increasing.  However, no one wants to read several paragraphs to understand what you might mean by D, so try to encapsulate it into two or three sentences, if you can.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Telling us what is not an answer (specifically your related but not an answer section) is good, but we need to know more of why they aren't answers.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I would like to see some motivation, perhaps near the beginning.

Then ask them if they are interested in your counterexample.  If they are responsive, they may give you some help, either in showing you are right (your counterexample works and a rough indication where the original proof breaks) or in showing you are wrong (the authors meant something else by what they said, and your counterexample does not apply).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Discussing the quality of a paper, or even a collection of statements, is not suitable for MathOverflow, primarily because of length, and secondarily because of the potential of a flame war.  Taking a particular statement, and showing a counterexample to the statement, if done briefly enough, is suitable.  I would couch it (as Lucia suggests) as &quot;Here is statement T, a theorem of Paper A.  My example E seems to show T is false, for basic reason R.  What am I missing? (Due to the technical nature of the proof of theorem T, I can't see where E breaks the proof.)&quot;&#xA;This puts you in a position of wanting to understand and asking for high level clarification, as opposed to critiquing (and inadvertantly suggesting the unreliability of the paper).  If it doesn't smell like you are trying to prove RH, it should be well received on this forum.  It might even help you find a stakeholder.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;A little weaker, but reasonable, approach would be to ask where the &quot;hidden hypotheses&quot; are in paper A.  It may be that the writing style obscures them from you, and someone familiar with the paper can show you where they are.  However, this can easily sound critical.  If your goal is to apply theorem T, it might be best (after having done your citation search) to ask for references to other uses of T.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Gerhard &quot;Don't Mention Collatz Conjecture Either&quot; Paseman, 2016.02.25.&lt;/p&gt;&#xA;" OwnerUserId="3402" LastActivityDate="2016-02-25T19:39:18.087" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

Even more drastically, closing a question, quite literally asks for more edits. Indeed, by now the question is closed as &quot;unclear what your are asking.&quot; In this way OP is told:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Thus if one takes the processes on this site at least somewhat seriously, OP is now &lt;em&gt;explicitly encourage to perform (further) edits to the question.&lt;/em&gt; This seems completely at odds with what appears to be the root-cause of the request, annoyance about too many edits.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Given 1. and the formulation of the meta-post it seems closure is proposed as some kind of reprimand against the poster. However, I do not consider this as a good way to proceed. A question should be closed if and only if it is not suitable for this site, best regardless to most everything else. If there is a problem with the behavior of a user, there are other ways to address it.

It is certainly very plausible that a referee will at some point (and likely this has already happened many times) want to tell authors about a post on MathOverflow relevant to the refereed paper. If the referee uses the URL generated from the 'share' link, they will accidentally reveal their identity. It is unreasonable to expect that users of this URL are aware that it may reveal their identity.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Discussion:&lt;/strong&gt; Personally, I couldn't care less about the Announcer badge (and I think the other moderators, and much of the community, agree).

This is an attempt at a fresh start of the discussion to find a long-term solution.&lt;/p&gt;&#xA;&lt;h2&gt;The current situation&lt;/h2&gt;&#xA;&lt;p&gt;The tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/lattices&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;lattices&amp;#39;&quot; rel=&quot;tag&quot;&gt;lattices&lt;/a&gt; is relatively large (at 300+ questions) its (highly-visible) tag-wiki excerpt says:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Lattices as they are used in number theory.

See &lt;a href=&quot;https://meta.mathoverflow.net/a/1761/121&quot;&gt;https://meta.mathoverflow.net/a/1761/121&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;Questions with this tag tend to be about either partially ordered sets, or discrete subgroups of Lie groups, or finite rank free abelian groups equipped with a quadratic form.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;The tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/lattice-theory&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;lattice-theory&amp;#39;&quot; rel=&quot;tag&quot;&gt;lattice-theory&lt;/a&gt; at 100+ questions is described as:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;The theory of lattices in the sense of order theory. For the number-theoretic notion, use the tag &amp;quot;lattices&amp;quot; instead.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;And mainly it is actually used only for this. (Thus, this is fine.)&lt;br /&gt;&#xA;There is also tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/euclidean-lattices&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;euclidean-lattices&amp;#39;&quot; rel=&quot;tag&quot;&gt;euclidean-lattices&lt;/a&gt;, which is more specialized.&lt;/p&gt;&#xA;&lt;h2&gt;Problem&lt;/h2&gt;&#xA;&lt;p&gt;The main problem as I see is that the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/lattices&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;lattices&amp;#39;&quot; rel=&quot;tag&quot;&gt;lattices&lt;/a&gt; is half-way deprecated while there is no clear alternative except for the order theory questions (and those about euclidean lattices).&lt;br /&gt;&#xA;[A side-problem is that at one place a tag is recommended that is advised against elsewhere but that is easy enough to fix.]&lt;/p&gt;&#xA;&lt;p&gt;Personally, I am not even quite clear about all the exact notions users might like to tag with some variant of &amp;quot;lattices,&amp;quot; and in earlier discussions sometimes users were talking sideways for reasons like this. For example while I can see what is roughly meant with &amp;quot;Lattices as they are used in number theory.&amp;quot; it is not exactly clear either.&lt;/p&gt;&#xA;&lt;h2&gt;The immediate aim&lt;/h2&gt;&#xA;&lt;p&gt;What I would like to achieve is to get some list of notions/subjects that might fall under &amp;quot;lattices&amp;quot; each with a viable name for a tag.&#xA;(For the order theory context this seems essentially achieved, via &lt;a href=&quot;https://mathoverflow.net/questions/tagged/lattice-theory&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;lattice-theory&amp;#39;&quot; rel=&quot;tag&quot;&gt;lattice-theory&lt;/a&gt;, but perhaps somebody sees room for improvement.   &lt;em&gt;Added:&lt;/em&gt; It appears not everybody is happy with the name of this tag. In fact, I do not consider it as optimal either as it does not directly convey what that it is about the order context. A solution could be to combine it with a related notion, like in &lt;a href=&quot;https://mathoverflow.net/questions/tagged/sequences-and-series&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;sequences-and-series&amp;#39;&quot; rel=&quot;tag&quot;&gt;sequences-and-series&lt;/a&gt;.

And, if this notion should get a tag, how this could be named distinctively.&lt;/p&gt;&#xA;&lt;p&gt;Based on such a list we could then create the new tags, definitely deprecate &lt;a href=&quot;https://mathoverflow.net/questions/tagged/lattices&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;lattices&amp;#39;&quot; rel=&quot;tag&quot;&gt;lattices&lt;/a&gt; and over time distribute the legacy questions as needed over the new tags.&lt;/p&gt;&#xA;&lt;h2&gt;tl;dr&lt;/h2&gt;&#xA;&lt;p&gt;Describe for one given context what &amp;quot;lattice&amp;quot; should encompass and propose a tag-name for this.&lt;/p&gt;&#xA;" OwnerDisplayName="user9072" LastEditorUserId="-1" LastEditorDisplayName="user9072" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2016-03-13T12:11:21.190" Title="What &quot;lattices&quot; do we need?"

It's &lt;em&gt;all&lt;/em&gt; just speculation and &quot;this is what I guess&quot; about the matter, or even sentiments along the lines of &quot;we shouldn't worry though, math will always be fun&quot;. And it could hardly be otherwise based on what little anybody really knows about human brains and AI (which I believe is beyond the scope of MathOverflow). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think the problem is on how the question is put: &quot;are there any fundamental reasons why a machine learning algorithm trained on a large database of formal proofs couldn't reach a level of skill that is comparable to humans?&quot; I think that question is shooting much too high: no one can really say!! But if the question were to be reworded so as to emphasize more what actually has been accomplished and what is currently in the offing, on a concrete level, that would allow for more influx of expertise. So what is wrong with the question now is too much gazing into the future. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(My own opinion on the subject, for what little it may be worth, is that the role of human vision and even our kinesthetic sense in creating mathematics has hardly been touched on. There are huge swaths of geometry and low-dimensional topology, for example, that are just &lt;em&gt;immensely&lt;/em&gt; difficult to cast into fully formal language, partly because the brain modules involved (the famous left/right brain dichotomy) are very different. I would aver that human vision endows human brains with a decisive advantage in certain respects for creating and communicating mathematics as we normally do it, at least for the foreseeable future, although I don't aver that this situation will never change.

(2) Even with the morphability of the question, an expert's effort to intuitively organize an important idea in a subject can be useful for awareness of ideas outside one's own research area and can be regarded as meaningful research work (these intuitions are shared during talks, but if you don't work in an area, you may never attend such talks). (3) Regarding oversimplification, it is always a danger, but the purpose here is to promote awareness across fields and to promote unity. We may assume that practicing researchers won't think they really understand a technical area when hearing a high level intuition pump like this. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Perhaps the problem is that the sheer number of these intuition pumps is too large. I argue that the level of idea I'm looking for should be sufficiently high that the number of such ideas will be relatively small. The deformation/rigidity example is pivotal in my subject and has had enormous influence, so having this high-level analogy gives immediate feeling of a central movement in a subject.

Let me begin by noting that by far the most frequent reviews are Close votes -- almost 37,000, and looking quickly most of the close votes (apart from skipping the question) are to Close a question (about 80% of the time) and only rarely to leave it open.  In contrast the review queue to reopen questions only has about 6000 reviews, and again most of these (maybe 80% again) are to leave the question closed, and only a small proportion of the votes are to reopen.  My own experience with these queues has been very similar to the overall numbers.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;To me this suggests that overall people have been doing a good job of removing unsuitable questions, and only relatively rarely are there borderline questions that are closed.  Even when these borderline questions are reexamined by other users, only rarely do they get reopened.  The fact that questions get reopened suggests also that some users really like or wish to see the question on this site.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Would it make sense to have a feature whereby a question that has been closed and then reopened is no longer considered for closing again?  That is, I am proposing a no &quot;double jeopardy&quot; rule.  &lt;strong&gt;Added&lt;/strong&gt;  Stefan Kohl in comments has proposed the alternative of requiring more votes in each new close/reopen cycle.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The pros:  It seems friendlier to do this, and respect the opinions of others who wish to have a question open.  (In my view, it is not symmetrical to want a question closed versus wanting it open.)  It will save us the occasional close/open war, which ends up getting heated.  Similar arguments came up in &lt;a href=&quot;https://meta.mathoverflow.net/questions/1046/what-shall-we-do-with-stone-soup&quot;&gt;What shall we do with stone soup?&lt;/a&gt; but nothing concrete seems to have been resolved there.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The cons:  Every once in a while one might get irritated by a question so bad that it's hard to understand why five others voted to reopen!  I find that there is a question of this sort that I voted to close the second time around;  I do feel that I would now prefer to be personally irritated, but let the question stand on general principle.  Another con would be that the proposed rule is irreversible (and I am generally wary of irreversible steps) -- this could be mitigated by either having moderators deal with extremely rare situations, or resetting the close/reopen possibilities if a question is edited.  &lt;strong&gt;Added&lt;/strong&gt;  Stefan Kohl's suggestion to increase the &#xA;number of close/reopen votes in each cycle, I think, gives a good way to guard against potential abuses. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In any case, I would be curious to hear what people think of this.

I have never been in Turkey, and I belive, the situation there is better than in Russia, where I live. Anyway, independently on this concrete case, it is evident for me that the idea to eliminate morality, humanity, solidarity and everything what is not yet well axiomatized, from profession, is a way to Animal Farm. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course it is natural, and moreover, inevitable that people separate  profession from the rest of the life. In science it's a part of abstract thinking. But this does not mean that professionals can become robots. This continues my old discussion with people at &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/1202/should-a-mathematician-be-a-robot/#Item_0&quot; rel=&quot;nofollow noreferrer&quot;&gt;tea.mathoverflow&lt;/a&gt;. Look what happens to laywers, jornalists, historians, artists, writers, state employees, even physicians in modern Russia. I assure you, they believe that they are good professionals. And they have reasons to think this. And (visually) they are not monsters from horror films. They just separate profession from the rest of the life &lt;em&gt;consistently, without doubts&lt;/em&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;When you do this, your professional life becomes simple, but only until the moment when you meet people from another profession. (Is there a necessity to explain this?)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You may think that this is something specifically Russian, an old tradition, a peculiarity that can't manifest itself in your country. But this is not so, I dare to say that the rational explanation of this is very simple: the lack of horizontal connections between people, and it can manifest itself everywhere. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And it is easy to see that when professionals separate their profession from the world too consistently (this happens all the way everywhere), this becomes an obstacle for the developement even for the developement of the profession itself. As an illustration, you can look at the &lt;a href=&quot;https://mathoverflow.net/questions/80146/is-the-mendeleev-table-explained-in-quantum-mechanics&quot;&gt;discussion about the axiomatization of quantum mechanics&lt;/a&gt; that I initiated not long ago (excuse me for self-references): a simple and natural mathematical question becomes controversial, because &quot;you actually can't ask this&quot;. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In 1990ies many Russian mathematicians left Russia. Some people say, 50%. I hope, that was good for Western mathematics, because many good mathematicians came to the West. But evidently  that was awful for Russian mathematics, because nobody from the West came to Russia instead. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So I want to ask, wouldn't it be better for mathematics if this necessity for Russian mathematicians to run away from their own country did not exist? I would say, the world would be much more comfortable for mathematicians if they could seek job everywhere: Russian mathematicians in the West, western mathematicians in Russia, and all mathematicians everywhere. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;What mathematicians can do for this is trying to be people, not robots. When you see a colleague in trouble, you shouldn't kill your human motives. Help him. In  &lt;a href=&quot;https://en.wikipedia.org/wiki/Neo-feudalism&quot; rel=&quot;nofollow noreferrer&quot;&gt;feudal societies&lt;/a&gt; where many mathematicians live now, the help from colleagues from abroad is often the only hope. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;EDIT 26.04.2016.&lt;/strong&gt; Stefan Kohl informed you already that Kivanç Ersoy has been released eventually. I also received this letter of 22.04.2016 from Giovanni Falcone. And four days before, 18.04.2016, I read news about &lt;a href=&quot;https://www.facebook.com/BykovDmitriyLvovich/posts/1151544921556332:0&quot; rel=&quot;nofollow noreferrer&quot;&gt;Sergei Mohnatkin&lt;/a&gt;, a Russian human rights activist. This can be a good illustration for our dispute. Sergei Mohnatkin is not an active mathematician, he only has a mathematical education, but for what I want to say this is not very important, because what happened to him happens to active mathematicians as well (see e.g. &lt;a href=&quot;https://en.wikipedia.org/wiki/Victor_Anatolyevich_Vassiliev&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt; or &lt;a href=&quot;https://en.wikipedia.org/wiki/Andrey_Piontkovsky&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt; -- however, these people have loud names in the scientific world, in contrast to Mohnatkin, that is the qualitative difference, I believe). Mohnaktin's crime was that once in 2009 he was going down the street (at that moment he worked as a pizza peddler, a person who brings pizza to clients, and he had pizza at his hands), and accidentally he saw how police disperse a demonstration in defence of Constitution. You know mathematicians: everything illogical causes protest in their souls. When he saw a policeman rudely dragging a woman into a police car, he stood up for this woman. The policeman dragged him as well, and put him into prison. He was released only two years later, in 2012.

I tend to think of this as a balancing act: loosening these restrictions allows (formerly allowed) a lot more of this sort of abuse; restrict it too much and you put folks in the position where they can't remove an obviously-unwise question even as it attracts useless answers. &lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;If you see it being abused, don't ever hesitate to undelete such questions. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;So they've tinkered with this over the years, and I think they consider it something like throwing a baby out with the bathwater if the restrictions were made any tighter than they are now. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The best thing to do, if you see a question with answer being deleted which is actually usefu, to our attention by raising a flag. &lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="-1" LastEditDate="2017-03-20T10:31:57.100" LastActivityDate="2016-04-12T11:59:53.540" CommentCount="16" ContentLicense="CC BY-SA 3.0" />

Please have a look to question:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/questions/232043/whats-the-probability-distribution-of-a-deterministic-signal-or-how-to-marginal&quot;&gt;What&amp;#39;s the probability distribution of a deterministic signal or how to marginalize dynamical systems? (functional integrals in probability theory)&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;By definition, if I were able to (well) define them, there would be no question at all.&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Since my objects are functional integrals, you can think for instance about Feynman's path integrals to illustrate the situation: brand new mathematical objects only &lt;strong&gt;formally/symbolically&lt;/strong&gt; defined at the beginning, takes time to make them well-defined.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So I've submitted one more question on MO, namely&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/questions/237084/sums-series-integrals-whats-next&quot;&gt;https://mathoverflow.net/questions/237084/sums-series-integrals-whats-next&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;where:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;I explicitly ask about the definition, the existence or the non-existence of my &lt;strong&gt;formally/symbolically&lt;/strong&gt; defined hypothetical mathematical objects in some theory I unfortunately do not know;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I provide links to other MO questions where those hypothetical mathematical objects naturally arise, in order to show they do not come from out of space;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;But I finally only get comments like:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;em&gt;Is it well-defined? No. Why not? Because you haven't defined it --- nor even given a hint as to what you mean or what properties such an integral should have.&lt;/em&gt;&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;*What properties do you want this operation to have? If you have a set of desiderata, they should be included in the question. If you don't, then of course the answer is that it's easy to define the operation any way you like (might as well take it to be identically zero, for example), and it's also easy to see that this question doesn't belong here&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What if Feynman would ask about his freshly introduced path integral on MO today?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Is it well defined? No.&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Why not? Because you haven't defined it&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Yes I know, but at least it is symbolically defined!&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;How to escape this vicious circle? At which point Feynman's path integral was sufficiently well/ill defined to deserve consideration from mathematicians?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So please, how should I reformulate my question in order to get answers like &quot;your object are in fact already known as $Y$ in theory $X$&quot; instead?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;FYI, I've asked the same question on SE:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://math.stackexchange.com/questions/1753921/we-have-sums-series-and-integrals-whats-next&quot;&gt;https://math.stackexchange.com/questions/1753921/we-have-sums-series-and-integrals-whats-next&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;and here I get more constructive answers like:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Possibly functional integrals or (in QM) path integrals&lt;/em&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It should be the converse, I guess.

What do you want to do with the construct?  What notion are you trying to capture?  If measure spaces, functional analysis, and calculus of variations do not hold some of the truth you seek, what are you seeking?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;My take on your question is that you want something that is different from measure on a function space, yet you still want to use the word &quot;sum&quot; .  Is that really appropriate?  If you are considering probability calculations, aren't you already in possession of a probability measure over which to operate?  What meaning (setting aside temporarily issues of existence) could you assign to a mean value of a collection of functions evaluated at x_0?  Shouldn't it be 0, as you will have -f(x_0) in your collection for each occurrence of f(x_0)?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There should be cases existing in measure theory or functional analysis where one looks at a measure on a function space.  Do a search for those terms, study the results, and then come ask your question and tell us why your study did not answer them.  At this point I just see a presentation I don't understand of an entity with probabilistic connotations that has some associated symbols that you say constitute a formal definition, but does not give me something to work with.  And you ask me if it exists?  I respond with &quot;So what if it does or doesn't? I can't use it or relate it to things I understand, so at present I can't help resolve that question.&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;A more acceptable version of the question would be: &quot; I have the following context where I am supposed to integrate over a function space rather than over a finite product of the reals.

Since the latter are allowed on MathOverflow, it would make little sense to disallow the former or relegate them elsewhither.  It is hard to argue that MathOverflow receives too many questions, or that there it is at a serious risk of being overflooded by questions by graduate students.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are also a number of questions being asked (and to avoid pointing the finger, &lt;a href=&quot;https://mathoverflow.net/questions/72800/every-real-function-has-a-dense-set-on-which-its-restriction-is-continuous&quot;&gt;I plead guilty myself&lt;/a&gt;), and often well-received, which are obviously motivated not by actual mathematical research, but just &quot;general intellectual curiosity&quot; (as in &quot;I &lt;em&gt;need&lt;/em&gt; to know this&quot;: I hope we can all agree that this is healthy).  Again, it would make little sense to allow those and not questions asked by graduate students.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think the main criteria should be something like: (1) the question's answer is not easy to find in standard textbooks on the subject, and (2) it has mathematical interest (either on its own or in order to solve a problem that does).  This should exclude most cases of homework.  I believe graduate students should be encouraged to take the time to think on their own before asking a question, and be sure to frame it carefully (and make sure it's not homework), but so long as they do so, and show their efforts, they should feel perfectly welcome to post on MathOverflow, and this should be made clear.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In a practical sense, apart from posters who will blatantly disregard guidelines and rules because they don't even read them, and a few cranks, I suspect there's more of a tendency to err on the side of self-censorship than in the other direction.  I've mentioned MathOverflow to a number of colleagues, and surprisingly many of them are apparently too shy to join, even to discuss their domain of research, because they feel intimidated by the level of the existing discussions, or for fear of seeming foolish (he who never hesitated to raise his hand and ask a question at a seminar, let him be the first to throw a stone ☺).

In truth, Lawvere wrote the paper for other purposes, and probably has a lot of ideas to communicate which are not summarized without major mental effort.  If they are, some editorial choices have to be made, and usually people do not volunteer to make such choices for you.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;A reasonable variation on your question (and one which you should ask of your advisor or whoever is guiding your studies and recommending you read the paper) is what are some of the major takeaways other readers got out of the paper.  For different readers the answer is likely to be different, and in asking the question you have to be prepared to deal with these other filters.  However, even such summary perspectives do not excuse you from building your own.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think the variation is a reasonable question to ask, but is not a good question for MathOverflow.  A good question for MathOverflow would be as follows: &quot;I have started reading paper X about Z in order to help my study of Y (specifically, I'm thinking about specific problem P).  Are there aspects of the paper that might help me with problem P?  Even if no application to P is visible, what are some of the takeaways of X and related questions Q that X might address (the closer to P the better)?&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Although answers to this version might be subjective, I see them as a good kind of subjective: anyone else who wants to approach X may in the answers see enough of a review of X to help decide if X is an appropriate paper for them.  Or people who are interested in P (or maybe even Q) may be interested in knowing about X.  As your version of the question stands, the answers may be too general and opinion-based to be useful to later readers.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Gerhard &quot;Objectively Opines Upon Subjective Suggestions&quot; Paseman, 2016.05.29.&lt;/p&gt;&#xA;" OwnerUserId="3402" LastEditorUserId="3402" LastEditDate="2016-05-29T23:00:02.307" LastActivityDate="2016-05-29T23:00:02.307" CommentCount="5" ContentLicense="CC BY-SA 3.0" />

Spam is one of the worst abuses of the system and we want to prune it out on the spot. The usual recourse for a site moderator is to destroy the account immediately with a few quick clicks. Applying this option, the software in place has various mechanisms which over time make it harder and harder for a spammer to return to ply his trade.&lt;/p&gt;&#xA;&lt;p&gt;Removing a spam link only hides the abuse and complicates site moderation.&lt;/p&gt;&#xA;&lt;p&gt;It must be exceedingly rare that a spam post actually does have content that meaningfully answers the question. Many spammers try to conceal a spam link within superficially relevant content, typically composed by a quick copy-and-paste from a Wikipedia page, and usually it will be obvious to all what's going on there. In any case, wherever you see spam in the sense explained above, the best option to raise a spam flag right away and let a site moderator destroy the offending account. (I don't think I've ever seen a case where there was content really worth preserving, but what I would likely do in that case is post that content separately [as a CW post]. Feel free to tell us in the flag if you think there is content worth preserving under a new post.)&lt;/p&gt;&#xA;&lt;p&gt;I'll take this opportunity to return to the issue of defining 'spam'. Some users interpret the word more broadly than the original sense of unwanted vendors, and use it for flagging posts which are unwanted or irrelevant for some other reason they have in mind. This would not be a problem, except that when you choose the spam option for flagging, you are partly training the software to recognize what 'spam' means, and using the word in the broader sense is then counterproductive. (I learned this from the MO user formerly known as 'quid'.)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Regarding Stefan's question in a comment about &amp;quot;who spams&amp;quot; (are they organized groups or individuals?), one of the SE Community Managers wrote to me as follows:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;On the question of who spams, it seems to be a little of each. We certainly have seen waves of similar spam randomly posted around the network. A few years ago we had a bunch of posts advertising a site to stream NFL games. It seems as if someone was hiring workers from countries with low labor costs to post URLs. These were removed pretty quickly, but we still have a bunch of football team names in our list of spammy words. ;-)&lt;/p&gt;&#xA;&lt;p&gt;We sometimes see spam from individuals: consultants advertising their services, overly enthusiastic users of a product, salespeople, etc. These aren't very organized, as a rule. Often the best thing to do is delete the content and leave a mod message. As you said on meta, any content is rarely worth keeping.&lt;/p&gt;&#xA;&lt;p&gt;There's not a lot of bot spam that gets through. Presumably, nobody has invested much time in creating bots for our Q&amp;amp;A format because spam doesn't stick around very long, so it's not profitable. I imagine CAPTCHAs take care of most the rest. Our SREs are really great, so there might be some other magic on the network level I don't know about.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;More information is here: &lt;a href=&quot;https://meta.stackexchange.com/questions/58032/what-are-the-spam-and-offensive-flags-and-how-do-they-work&quot;&gt;What are the “spam” and “rude or abusive” (offensive) flags, and how do they work?&lt;/a&gt;&lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="-1" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2016-07-28T17:44:43.503" CommentCount="8" ContentLicense="CC BY-SA 3.0" />

The latter question has one linked question, but it is other question, not the duplicate.)&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;What are the reasons for this behavior?&lt;/li&gt;&#xA;&lt;li&gt;Is this connected to the fact that the closure was before MathOverflow joined Stack Exchange network? Do all pre-migration posts behave in this way? Or is there some other reason? (Additionally, is this MO-specific, or does the same problem occur network-wide?)&lt;/li&gt;&#xA;&lt;li&gt;Other than simply adding a link somewhere (by adding a comment or editing one of the questions or one of the answers) are there some other ways to correct this?

I understand the impulse, since news like this propagates slower than you might think.  My recollection is that in a few cases where a member of the MO community died, we added a banner to the top of the site, but posting this as a normal question is simply not what the site is for (this is easily seen from: &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;https://mathoverflow.net/help/on-topic&lt;/a&gt;).  I think this is particularly clear since Yoccoz didn't have any connection I know of to MO, but in general, I don't think we want to be in the business of sorting out which such events to announce and which not. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think it's fine to make a post in meta about someone involved in the community passing away (or has a more happy life event; maybe I should have posted when my daughter was born).  I think posting about every mathematician who dies is not really what meta is intended for, but I doubt anyone will object to it from time to time. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;EDIT:&lt;/strong&gt; I have to admit, I'm slightly confused about the downvotes.   There are a lot of gray areas in what is an acceptable question and what isn't, but announcements are very clearly outside site policy.  I understand the impulse, because there aren't a lot of places to make announcements to a broad audience of mathematicians, but there are a lot of announcements that people out in the world want to make, and they could easily drown out the questions (most of which are much less notable than this news).  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Maybe I muddied the waters too much by talking about whether it was appropriate to post on Meta.  I think if you read the explanation of what Meta is (&lt;a href=&quot;https://mathoverflow.net/help/whats-meta&quot;&gt;https://mathoverflow.net/help/whats-meta&lt;/a&gt;), then my reading is that announcements are not really part of the intended purpose, but Meta doesn't really have a clear policy on what's kosher and what not, so it's harder to make firm pronouncements.  &lt;/p&gt;&#xA;" OwnerUserId="66" LastEditorUserId="-1" LastEditDate="2017-04-13T12:58:29.637" LastActivityDate="2016-09-10T00:39:04.357" CommentCount="13" ContentLicense="CC BY-SA 3.0" />

Tags help with searching, although in this case it is very likely that the question will contain the word &quot;database&quot; or &quot;databases&quot;, so probably the tags will not improve the search that much for this type of questions. But the tags are also used in &lt;a href=&quot;https://meta.stackexchange.com/questions/27566/would-it-be-feasible-to-tie-the-tags-of-a-new-question-to-the-related-questions-l&quot;&gt;the algorithm which selects the list of related questions&lt;/a&gt; (shown for each question in the sidebar on the right). If the questions with similar focus have similar tags, this might improve that list and thus help the askers to see whether similar questions have been asked in the past.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I am not really sure that creating a new tag is a good option. Mainly for the reason that there are at most 5 tags per questions, so it is not good to create too small tags for things which fit nicely under some moderately large tag,&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So my personal preference is to use &lt;a href=&quot;https://mathoverflow.net/questions/tagged/online-resources&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;online-resources&amp;#39;&quot; rel=&quot;tag&quot;&gt;online-resources&lt;/a&gt;. As you can see in the list of the questions linked above, it seems that this is (in most cases) consistent with the tagging of questions about this topic so far. However, one possible objection for using this tag might be that such a database &lt;em&gt;need not be online.&lt;/em&gt; (For example, suppose that somebody asks &quot;Can I find somewhere all groups with the following property together with their character table?&quot; Then this would be a valid answer which would not include any online resource: &quot;Such list can be generated in GAP using the following commands...&quot;)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have also &lt;a href=&quot;https://mathoverflow.net/review/suggested-edits/69628&quot;&gt;suggested&lt;/a&gt; the &lt;a href=&quot;https://mathoverflow.net/tags/online-resources/info&quot;&gt;tag-wiki for online-resources&lt;/a&gt; where I explicitly mentioned databases of mathematical objects.

Alternatively, you can buy Adobe Pro, but that's a lot more than you need if you only need to OCR. Other programs tend to output text as Word files, and tend to ruin mathematical equations.

What are the reasons why this feature request currently works the way it does?&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;It seems that the main purpose of this feature is not to bring unanswered questions to the attention of users. It is about bringing attention to answers. I will quote from this post: &lt;a href=&quot;https://meta.stackexchange.com/questions/279203/how-can-we-make-the-purpose-of-community-bumping-more-obvious&quot;&gt;How can we make the purpose of Community &amp;quot;bumping&amp;quot; more obvious?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;To be clear, the intent here is to resurface questions that &lt;em&gt;someone has attempted to answer&lt;/em&gt;, but which haven't yet attracted any votes to either confirm the usefulness or decry the worthlessness of the answer(s) that've been posted.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;So changing this to bumping questions without answers would mean using this feature for a different purpose than originally intended.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As with any automated system, it is probably difficult to define good criteria how to choose questions which should be bumped. (I.e., questions where additional attention might be useful.) I do not know whether all details how community user selects the questions are publicly known, the algorithm might be quite complicated. For example, only recently I learned that &lt;a href=&quot;https://meta.stackexchange.com/questions/99672/community-should-discriminate-more-when-bumping-unanswered-questions/99690#99690&quot;&gt;number of views&lt;/a&gt; is also taken into account.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Is my understanding that community user does not bump questions with no answers correct?&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;I wrote &lt;em&gt;questions with no answers&lt;/em&gt; rather than &lt;em&gt;unanswered questions&lt;/em&gt; since by the meaning commonly used here on Stack Exchange network, the term &lt;a href=&quot;https://meta.mathoverflow.net/tags/unanswered-questions/info&quot;&gt;unanswered question&lt;/a&gt; includes question having an answer, which is neither upvoted  nor accepted.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;After this modification, the answer to your question is: &lt;strong&gt;Yes&lt;/strong&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Some links to the basic info about community user can be &lt;a href=&quot;https://meta.mathoverflow.net/tags/community-user/info&quot;&gt;found in the tag-wiki&lt;/a&gt;. In particular, this post contains many details about what community user does: &lt;a href=&quot;https://meta.stackexchange.com/questions/19738/who-is-the-community-user&quot;&gt;Who is the Community user?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Specifically to your question this meta.SO post seems to be relevant: &lt;a href=&quot;https://meta.stackexchange.com/questions/217884/community-user-does-not-bump-questions-that-never-had-an-answer&quot;&gt;Community user does not bump questions that never had an answer&lt;/a&gt; I will point out that it is tagged as &lt;a href=&quot;/questions/tagged/status-bydesign&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;status-bydesign&amp;#39;&quot; rel=&quot;tag&quot;&gt;status-bydesign&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Are older questions with no answer doomed?&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;The exact quote from your post is: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;So if I understand correctly, a question with no answer at all is consigned to oblivion if there are no answers or edits.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;In my opinion, the answer to this is certainly &lt;strong&gt;No&lt;/strong&gt;. (Although the likelihood to getting an answer is definitely much smaller.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Bump by community user is not the only way how a question can be &lt;a href=&quot;https://meta.mathoverflow.net/tags/bumping/info&quot;&gt;bumped&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Already in the &lt;a href=&quot;https://meta.mathoverflow.net/questions/1110/how-to-wake-up-an-old-question/1111#1111&quot;&gt;answer you linked&lt;/a&gt;, apart from editing also &lt;a href=&quot;https://meta.mathoverflow.net/tags/bounty/info&quot;&gt;bounty&lt;/a&gt; is mentioned as a possibility.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;And even if an old question is not bumped and does not get to the front page, it is not the only way it can get to attention of potential answerers.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Already here on MO there are many ways in which the users can get to that question. The list of the &lt;a href=&quot;https://mathoverflow.net/questions?sort=newest&quot;&gt;most recently asked&lt;/a&gt; or &lt;a href=&quot;https://mathoverflow.net/questions?sort=active&quot;&gt;most recently modified question&lt;/a&gt; are not the only things which the users see. There are many other places where the question is listed. Perhaps some users browse &lt;a href=&quot;https://mathoverflow.net/questions?sort=unanswered&quot;&gt;through unanswered questions&lt;/a&gt; to find some interesting gems or even simple questions which, for some reason, lack answers. There might be some users who occasionally browse through &lt;a href=&quot;https://mathoverflow.net/questions/224192/integrating-a-series-expansion-of-mboxfracx-lfloor-x-rfloor-coming-from-f&quot;&gt;questions with tumbleweed badge&lt;/a&gt;, to find questions which did not receive much attention and to see whether they are able to help with some of them. Somebody might spot the old question among favorites of some user or in the sidebar among related questions to some recent question. Some users even have collected in their profiles links of some stuff on MO which they consider interesting. Somebody can get to an old question because it pops out when they are searching for posts about some topic they are interested in. And there are many other places where the question might appear. (Admittedly, the number of views will increase more rapidly after the question has been bumped, but it will probably continue to grow even without bumping. By randomly browsing questions with &lt;a href=&quot;https://mathoverflow.net/help/badges/48/popular-question&quot;&gt;popular tag badge&lt;/a&gt;, you might get a rough idea how long it took those questions from posting until gaining 1k views. Some statistics about how soon after a question is asked it gets answer can be found using SEDE. I will mention &lt;a href=&quot;https://math.meta.stackexchange.com/questions/12131/distribution-of-time-to-first-answer-in-mathstackexchange&quot;&gt;this post on meta.math.SE&lt;/a&gt;, the query provided there can &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/154746/question-answer-time-interval&quot; rel=&quot;nofollow noreferrer&quot;&gt;also be used for MathOverflow&lt;/a&gt;. However, the detailed analysis would require more work. Since this is not exactly main focus of this question, let's leave it for another time - or for a user who is interested enough to do the work now.)&lt;/li&gt;&#xA;&lt;li&gt;It is possible to bring attention to a question by mentioning it in chat. (At the moment the &lt;a href=&quot;http://chat.stackexchange.com/rooms/info/9369/mathoverflow&quot;&gt;main chatroom&lt;/a&gt; seems to be almost unused, so that would probably not generate too many new views. But it is possible that this might change in the future. However, there is a very active &lt;a href=&quot;http://chat.stackexchange.com/rooms/info/9417/homotopy-theory&quot;&gt;room focused on homotopy theory&lt;/a&gt;, so for inquiries from this area chat is a good option. And maybe in the future &lt;a href=&quot;https://meta.mathoverflow.net/questions/355/specialized-chat-rooms&quot;&gt;some other rooms&lt;/a&gt; will be created and become active. I will also mention that &lt;a href=&quot;http://chat.stackexchange.com/?tab=site&amp;amp;sort=active&amp;amp;host=math.stackexchange.com&quot;&gt;math.SE&lt;/a&gt; has several chat rooms. &lt;a href=&quot;http://chat.stackexchange.com/rooms/info/36/mathematics&quot;&gt;The main room&lt;/a&gt; is very active, other rooms less so, but some of them had periods of rather big activity in the past. If you decide to post something there, it might be reasonable to read &lt;a href=&quot;https://math.meta.stackexchange.com/questions/3890/main-chatroom-etiquette-rules&quot;&gt;rules of the room&lt;/a&gt; first.)&lt;/li&gt;&#xA;&lt;li&gt;There are even some rather bizarre ways how the question can get renewed attention. They happen probably rather rarely, but they do happen. For example, your question might be used in &lt;a href=&quot;https://meta.stackexchange.com/tags/review-audits/info&quot;&gt;review audit&lt;/a&gt;. (Although that gives only one additional view by the reviewer, unless they decide to edit or answer the question.) Or the question might be bumped because a spammer post an answer advertising some product. (Spam occasionally appear here - some rough stats were &lt;a href=&quot;http://chat.stackexchange.com/transcript/10243?m=30644722#30644722&quot;&gt;mentioned here&lt;/a&gt;.) However spam is probably more frequently posted as questions rather than answers.&lt;/li&gt;&#xA;&lt;li&gt;And there are certainly many ways how somebody can get to the question from outside MO. For example, it might be mentioned on some blog or website. Questions from MO definitely appear on social media like Facebook and Twitter. (For example, &lt;a href=&quot;https://www.google.com/search?q=%22mathoverflow.net/q%22+site:twitter.com&quot; rel=&quot;nofollow noreferrer&quot;&gt;this Google search&lt;/a&gt; returns several MO question posted on twitter. And I am pretty sure that many more MO-related tweets than the few results found by this simple search exist.) Or it can be discussed even in email exchange or discussion over lunch with a colleague.&lt;/li&gt;&#xA;&lt;li&gt;And probably one of the most frequent ways is that somebody gets to some question is finding it using Google (or other search engine). The users with 25k+ reputation can &lt;a href=&quot;https://mathoverflow.net/help/privileges/site-analytics&quot;&gt;see in site analytics&lt;/a&gt; what are the most frequent sources of traffic no MO. But even without access to site analytics it is easy to see that MO questions typically rank high among result of google searches.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="-1" LastEditDate="2017-04-13T12:58:29.637" LastActivityDate="2016-10-14T08:48:08.553" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

I wonder whether this could be done without changes in the bounty system and bounty period.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;What about the following proposal? (If there is need of more detailed discussion, I can post it as a separate question. But I thought that posting it here first to get at least some feedback of the MO community would be reasonable.)&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;It seems that the OP has mainly the following situation in mind: A user offers a bounty for some question, but they do not receive the answer they were hoping for. Although they might continue adding new bounties indefinitely, they would rather quickly run out of reputation points. Are there other possibilities to attract attention to such questions?&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&lt;strong&gt;Proposal.&lt;/strong&gt; What about creating a separate place for this purpose, either in the form of a &lt;em&gt;chat room&lt;/em&gt; or as a &lt;em&gt;separate thread&lt;/em&gt; here on meta? Here such questions could be collected. That would be beneficial to the users who offered the bounty - in that they would get additional attention for the question. And it would be also good place for users who are looking for interesting questions. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;It would be not the first thread collecting interesting questions on this meta: &lt;a href=&quot;https://meta.mathoverflow.net/questions/1967/interesting-and-not-sufficiently-answered-questions-on-math-se&quot;&gt;Interesting (and not sufficiently answered) questions on math.SE&lt;/a&gt; But perhaps chat room would be less intrusive than a separate thread. Whether the chosen implementation would be to create a chat room or a thread on meta, I do not think it would fill too quickly if the condition for posting would be that at least one bounty has already been placed on the post. (This condition would also prevent users from misusing this by posting there all questions they have.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have made a similar proposal on Mathematics site. It seems that the suggestion was met with some enthusiasm &lt;a href=&quot;https://math.meta.stackexchange.com/questions/23647/could-list-of-unresolved-past-bounties-be-useful&quot;&gt;judging from the upvotes on meta&lt;/a&gt;. (You can also have a look at &lt;a href=&quot;https://math.meta.stackexchange.com/questions/23647/could-list-of-unresolved-past-bounties-be-useful/23715#23715&quot;&gt;the rules proposed there&lt;/a&gt; - the conditions which the question should meet before it is posted there.) However, the &lt;a href=&quot;http://chat.stackexchange.com/transcript/43020/2016/7/26&quot;&gt;chat room created for this purpose&lt;/a&gt; is so far almost unused. (But I would wait a bit before calling this a complete failure. Maybe I was also at fault for not promoting the idea among math.SE users enough. Since there is an overlap between userbase of the two sites, perhaps my post can as a side effect also help to promote that chat room, but the main purpose of this post is to find out what MO community thinks about something similar here.) Considering that MO and Math.SE are rather different (if we compare the size of userbase, activity on meta, rate of asking questions, etc.), it is possible that it could work on MathOverflow even if it fails on Math.SE (and vice versa).&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;I will add a few comments about the questions posted by the OP - which are unrelated to the above proposal.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Is bounty period sufficient?&lt;/em&gt; Here we should first ask: sufficient &lt;em&gt;for what&lt;/em&gt;. The purpose of the bounties is partly to incentivize answerers, but mainly to bring attention to the question. So efficiency of the bounties can be measured based on the number of additional views. I guess users skilled with Data Explorer have certainly created various queries examining this, see for example &lt;a href=&quot;https://math.meta.stackexchange.com/questions/20155/how-effective-are-bounties&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The additional attention depends also on the size of site - mainly on the number of users. And also on the number of bounties. (It is difference whether the additional attention is divided between 10 featured question and 100 featured question. So from this viewpoint making the period longer might increase the number of featured question and be actually counterproductive.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Can bounty period be changed?&lt;/em&gt; The important question here is whether SE team adjusts such settings individually per site or only for the whole network. Although I have no official source of this, it seems that things related to bounties are network-wide settings. See, for example, &lt;a href=&quot;https://meta.stackexchange.com/questions/284657/are-bounty-parameters-network-wide-or-per-site-settings&quot;&gt;here&lt;/a&gt;, &lt;a href=&quot;https://gis.meta.stackexchange.com/questions/4245/if-no-answers-are-offered-in-a-bounty-automatic-message-should-not-be-you-must/4247#4247&quot;&gt;here&lt;/a&gt; and &lt;a href=&quot;https://gis.meta.stackexchange.com/questions/4149/rewarding-bounty-after-bounty-finished-when-question-posted-before-end-of-bounty/4150#4150&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="-1" LastEditDate="2017-03-20T10:31:57.100" LastActivityDate="2016-11-27T16:25:54.003" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

So if the two tags are supposed to serve the same purpose, perhaps better solution than making a synonym would be removing (transcendence) and replacing it by (transcend.-number-theory). (I vaguely recall that moderators can do this without bumping all questions, probably by merging the tags and then removing the empty one - of course I might remember this incorrectly. But even if the tag can be replaced in most questions without bumping, at least the questions tagged (trancendence) which are not about transcendental number theory would have to be bumped to be retagged correctly.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;P.S.

If MO is a purely abstract community of minds sharing ideas, where one cannot speak about real concerns about research, it seems not to be suited to those questions. If metaMO is intended, as the &quot;meta&quot; suggests, to deal with technical, organizational and political issues relative to MO, it also seems unfit to them. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I believe those questions are of real interest and importance, but for now I wrote this post to gather some comments, ideas and impressions.&lt;/p&gt;&#xA;" OwnerUserId="43737" LastActivityDate="2023-11-07T11:32:16.187" Title="What about talking about life?

Putting aside the choice of name and avatar, there has been no detectable untoward behavior coming from this user, and the one post coming from that account so far has reasonable content.&lt;/p&gt;&#xA;&lt;p&gt;I agree however with the judgment of arjafi that the choice of name and avatar looks trollish, i.e., was likely chosen in order to provoke or annoy some users, and what this means officially for moderators is that the account will in future be watched more closely than it would be ordinarily. Really my advice to the user would just be &amp;quot;knock it off&amp;quot; or &amp;quot;cut the crap&amp;quot; -- this is a community of professional or professionally-minded mathematicians, and as such we have little tolerance for nonsense or games. To the rest of the community, I would counsel not to feed any flames: if it annoys, confine yourself to rolling your eyes, but nevertheless scan for usefulness of content and of course flag any problematic behavior (besides the name and photo).&lt;/p&gt;&#xA;&lt;p&gt;(By the way, I would feel just the same if the username were &amp;quot;IHateDonaldTrump&amp;quot; with horns coming out of the head: it's exhibiting poor judgment, and is puerile.)&lt;/p&gt;&#xA;&lt;p&gt;At issue is a sometimes fine line between anonymity (no name) vs. pseudonymity (fake name). In general we prefer, as befitting professionals, that people use their real names and photos, although we respect that there can be compelling need in some cases for anonymity. &lt;em&gt;Pseudonyms&lt;/em&gt; are trickier and must be dealt with case-by-case. We have for instance the celebrity name Bugs Bunny, which I consider harmless (and who has demonstrated good mathematical taste and insight). On occasion we see names or avatars of dead mathematicians (Banach, Skolem, etc.), which I find unproblematic, for the most part.

So you can see many Chinese mathematicians named as Zhang, Wang, Li, etc. In the past, this seems not to be a big problem in the math community since some famous Chinese mathematicians happen to have an uncommon family name such as Yau and Tao. But as there are more and more famous Chinese mathematicians with common family name such as Yitang Zhang coming out, this can easily cause some confusions. For example, &quot;Zhang's Theorem&quot; really provides little information about the author &quot;Zhang&quot; since &quot;Zhang&quot; is too common. This terms can not only cause confusions (we may have &quot;Zhang's Theorem&quot; in every area of math in near future!) but also &lt;strong&gt;indicates little credit to the person who proved the theorem&lt;/strong&gt;. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I suggest that when we cite a paper from a Chinese author or name a theorem, we should use full name such as &quot;Yitang Zhang&quot;, instead of &quot;Zhang&quot; or &quot;Y. Zhang&quot;(even with &quot;Y.&quot;, this is still too common). This should not be viewed as a discrimination nor a preference: this principle can be used whenever there is a risk of confusion (e.g. be more specific about &quot;Smith&quot;, &quot;Vinogradov&quot;).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;PS: one motivation of my suggestion is this question: &lt;a href=&quot;https://mathoverflow.net/questions/28892/which-pair-of-mathematicians-has-the-most-joint-papers&quot;&gt;Which pair of mathematicians has the most joint papers?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One answer is &#xA;&quot;This is a frivolous item solely to demonstrate the pitfalls of running MathSciNet searches and working with large datasets:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Type &quot;Wang and Zhang&quot; in the author field and get a list of 2417 items.

I could not help myself from thinking how -and if- such a feature could also be implemented here at Mathoverflow. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I can clearly understand that maybe this is not that simple: Refereeing a paper in Physics can be significantly different than refereeing a paper in mathematics. Detailed checks of computations and statements seem -well at least ideally- more important in refereeing of mathematical papers while the overall estimation of the novelty of an idea or model and its relation to experimental data or phenomenological approaches seem to be the focus in lots of cases of physics papers. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, I feel that the community might have the power to add such a feature in this site, at least for some specific categories, where there are enough experts willing to undertake the job (for example algebraic geometry or number theory). I am thinking that initially, it would not necessarily have to do with refereeing of full papers (I guess that few mathematicians would like to initially submit their full paper in the site; lots would prefer a mainstream journal). However it might have to do with refereeing specific proofs of new results or parts of the whole argument. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;P.S.:&lt;/strong&gt; Although one might say that initially this could just be a &lt;em&gt;check-my-proof&lt;/em&gt; feature, what I am having in mind is something more substantial, with the ambition to evolve in more conceptual &lt;strong&gt;community-reviewing&lt;/strong&gt; of both problems and arguments and finally whole papers. &lt;/p&gt;&#xA;" OwnerUserId="85967" LastEditorUserId="85967" LastEditDate="2017-01-06T01:58:39.830" LastActivityDate="2019-07-18T08:38:00.377" Title="Community Peer-Review in Mathoverflow" Tags="|discussion|feature-request|" AnswerCount="5" CommentCount="14" ContentLicense="CC BY-SA 3.0" />

Or perhaps it will be flawed in a way that will be good to learn. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;With the support of the MO community, such a system could be implemented at first on a provisional basis, with the promise to remove it after a year or two, say, if it fails. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are, of course, many practical issues to consider.

I think some are on publishing.mathforge.org, and there are open publishing fora and various blogs (including that of John Baez and his mention of the Selected Papers Network).  Collectively, they should cover many of the main issues concerning an online review system.  I invite others to edit this post and add links to any discussions they find helpful.

It seems to me that (like ArXiv) an add-only repository is needed, so that context for review efforts is stable. I think issues like research arising from reviews needs to be anticipated. (If everyone were meticulous about saying &quot;Based on web paper X (starting from lexeme Y through Z), we can state the following improvement...&quot;, there would be few problems.  Even then there may be political and social issues surrounding attribution of ideas.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It might make sense to include discussion of existing papers as well.  Until the WML is set up, one needs to take care of establishing and archiving a copy of the paper so as not to violate copyright issues.  Even if a digital copy is not established, one needs to make a reference to a non digital copy that all reviewers can resolve reliably.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I am in favor of open and transparent reviews where the reviewer has a registered and established identity.

After all this is a Q&amp;amp;A site, and eventually the answers are supposed to reach finalized state, so why not use a separate section to certify tricky answers once and for all?

(Such as front page, list of related questions, search results.) If the same information can be displayed without the title of particular question taking much more space than others, it is probably an improvement.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This effect is more visible if you compare it with other titles not having this size, but even if you simply look at the search results of &lt;a href=&quot;https://mathoverflow.net/search?q=title%3Adisplaystyle&quot;&gt;title:displaystyle&lt;/a&gt; or &lt;a href=&quot;https://mathoverflow.net/search?q=title%3Adfrac&quot;&gt;title:dfrac&lt;/a&gt; you can probably see what I mean.

However, the manner in which the claim is being made raises real&#xA;  questions about its correctness.&lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;Moore is apparently not a mathematician by training.

Moore&quot; or &quot;J.&#xA;  P. Moore&quot;. The chances that an amateur without previous mathematical&#xA;  publications could solve these important and famous problems are, for&#xA;  all practical purposes, zero. (Prior to his celebrated recent success&#xA;  on the twin-prime problem, Yitang Zhang, a professional mathematician,&#xA;  had two published papers in good journals.)&lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;Instead of placing his claimed solution on the arxiv, or publishing it&#xA;  in a journal -- as would be customary in such a case -- Moore is&#xA;  selling his solutions online in three different books for $27.05 each.&#xA;  One book is entitled either &quot;The Proof of the Primes&quot; or &quot;The Proof of&#xA;  Primes&quot;, a title that doesn't make much sense mathematically.&#xA;  &lt;a href=&quot;http://recursed.blogspot.de/2014/02/twin-prime-problem-and-goldbach.html&quot; rel=&quot;nofollow noreferrer&quot;&gt;(source)&lt;/a&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;So I think it's safe to assume that &quot;spam&quot; fits here, as it's promoting a product (the article / book) that the creator stands to profit from.&lt;/p&gt;&#xA;" OwnerUserId="89684" LastActivityDate="2017-01-30T10:05:00.167" CommentCount="5" ContentLicense="CC BY-SA 3.0" />

I would be grateful if you could have a look at it.&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This should definitely not be overused - comments are primarily intended for things related to post where the comment is posted. And it would probably be considered impolite to ping somebody simply because they are expert but had no previous interaction with related questions of yours. In short, you should use your own judgement to decide where is the boundary.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt; &#xA;&#xA;&lt;p&gt;And of course, if you stumble upon the user in &lt;a href=&quot;/questions/tagged/chat&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;chat&amp;#39;&quot; rel=&quot;tag&quot;&gt;chat&lt;/a&gt;, you can ask there.

The tag have since been removed.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course, adding the tag did not create notification, but it increased the likelihood that a particular user looked at the specific question. And this maybe shows at least a bit that using correct tags can improve the probability that expert in a particular area will look at your question. It seems quite reasonable to assume that many users look mostly at &lt;a href=&quot;https://mathoverflow.net/search?tab=active&amp;amp;q=intags%3amine%20is%3aq&quot;&gt;their favorite tags&lt;/a&gt; and at the tags from areas they are familiar with.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt; &#xA;&#xA;&lt;p&gt;EDIT 2: Since I see that you have tagged your post as &lt;a href=&quot;/questions/tagged/feature-request&quot; class=&quot;post-tag required-tag&quot; title=&quot;show questions tagged &amp;#39;feature-request&amp;#39;&quot; rel=&quot;tag&quot;&gt;feature-request&lt;/a&gt;, let me comment also a bit on this. The question whether or not this type of ping works is in my opinion closer to &lt;a href=&quot;/questions/tagged/support&quot; class=&quot;post-tag required-tag&quot; title=&quot;show questions tagged &amp;#39;support&amp;#39;&quot; rel=&quot;tag&quot;&gt;support&lt;/a&gt; than feature request. If you really want to make this into a feature request, you should definitely spell out more detail. (For example, how would you deal with several users pingable by the string used. For example, writing @Martin would match many users on the site. Even if this feature would be restricted to &lt;em&gt;exact&lt;/em&gt; username, duplicate usernames are not disallowed, so there is a possibility that this could ping more than one user.) Another question is whether such a feature question should be posted here or on the &lt;a href=&quot;https://meta.stackexchange.com/&quot;&gt;main meta&lt;/a&gt;, since it would influence the whole SE network.

One example I was able to find quickly: &lt;a href=&quot;https://meta.mathoverflow.net/questions/2931/how-can-i-tell-if-my-question-is-appropriate-to-mathoverflow-or-if-i-should-just&quot;&gt;How can I tell if my question is appropriate to MathOverflow or if I should just put a bounty on it at Math.SE?&lt;/a&gt; You can find a few more in &lt;a href=&quot;https://mathoverflow.net/questions/tagged/math-stackexchange&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;math-stackexchange&amp;#39;&quot; rel=&quot;tag&quot;&gt;math-stackexchange&lt;/a&gt; tag. &lt;/li&gt;&#xA;&lt;li&gt;Some people ask such question on meta.math.SE. Again a random example: &lt;a href=&quot;https://math.meta.stackexchange.com/q/23091&quot;&gt;Can we move to an unanswered question to MathOverflow&lt;/a&gt;. You might find some other such inquiries in &lt;a href=&quot;https://math.meta.stackexchange.com/questions/tagged/mathoverflow&quot;&gt;mathoverflow tag&lt;/a&gt;, although from a brief look at the questions in that tag it seems, that asking about general criteria how to decide what belongs on MO is more frequent than asking about a specific question.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Although I provided only a handful of examples, I guess that users who occasionally look into MO chat room or frequent at least one of the two meta sites mentioned above can confirm that such questions appear repeatedly. I suppose that they will get probably best possible answer here at meta.MO. (The main MO chat room is hardly ever visited - the &lt;a href=&quot;http://chat.stackexchange.com/rooms/info/9369/mathoverflow&quot;&gt;room info&lt;/a&gt; shows about 3k messages which gets close to about 2.5 messages per day. Meta.math.SE is probably a better place, but still on this meta the question gets attention of more MO users.)&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Would it be good idea to create a single thread where such inquiries would be posted as answers?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;There already are a few threads for the purpose of getting discussions with similar focus in one place, rather than having many separate questions about very similar issue. This is done usually for things which are likely to be asked repeatedly. (For example, &lt;a href=&quot;https://meta.mathoverflow.net/questions/223/requests-for-reopen-and-undelete-votes-for-on-hold-closed-and-deleted-question&quot;&gt;Requests for reopen and undelete votes for on-hold, closed, and deleted questions&lt;/a&gt;, &lt;a href=&quot;https://meta.mathoverflow.net/questions/1967/interesting-and-not-sufficiently-answered-questions-on-math-se&quot;&gt;Interesting (and not sufficiently answered) questions on math.SE&lt;/a&gt;, &lt;a href=&quot;https://meta.mathoverflow.net/questions/194/help-improve-tagging&quot;&gt;Help improve tagging!&lt;/a&gt;, &lt;a href=&quot;https://meta.mathoverflow.net/questions/862/help-cleanup-tags&quot;&gt;Help cleanup tags!&lt;/a&gt; and probably a few others I am unaware of.)&lt;sup&gt;1&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I will stress that the suggestion is &lt;em&gt;only for questions already posted at math.SE.&lt;/em&gt; I consider this situation slightly different from asking about suitability of a question on MO where only some description is given by the OP. The difference is that if a question is already posted on some site, it is possible to view the question in full and it is easier to judge whether or not it is suitable for MO than from a vague description. And if a question already exists, the OP might get also some suggestions on how to improve the question.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I suppose that concentrating queries like this would improve the chances that the user asking about this will get at least some feedback. And if somebody asks about this in chat or on some other meta, such thread on MO would be at least a good place where to direct users asking this.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Additionally I will ask also this:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;If the consensus is not to create single thread, what should be recommended to people who want to ask about this as the best course of action? Should they simply post a new question here on meta.MathOverflow.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;For example, if I - or somebody else - would like to make a suggestion to users who asked about this in chat (see the examples linked above), where should I direct them?&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;On the technical side, I will mention that it is possible to disassociate a post from a user and change the post owner to the &lt;a href=&quot;https://meta.mathoverflow.net/tags/community-user/info&quot;&gt;Community user&lt;/a&gt; - although this has to be requested from SE staff. (IIRC this cannot be done by moderators.) So if the outcome of this discussion is that creating such a thread could be useful, whoever posts the question can ask for the question to be disassociated from their account, so that they do not receive ping from each new answer - if they wish to do so. (I am not sure to which extent this practice is common for &quot;long threads&quot; like this on MO.) &lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="-1" LastEditDate="2017-03-17T10:13:04.417" LastActivityDate="2017-02-11T10:34:50.987" Title="Thread for asking about suitability of math.SE question on MO?"

(Disclaimer: I didn't vote up or down on the question, and (obviously) wasn't one of the closers; I am responding as a site moderator with fairly broad acquaintance with how the MathOverflow site works.)  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;You say the question is &quot;clearly research level&quot;. If you mean this question is posed with a view to doing research to simplify the proof of the FLT (as suggested by the question title), then I think the message that is coming from commenters such as Olivier is that the question as posed is really not the right type of question to ask. Please bear in mind that the reason for closure given, &quot;unclear what you're asking&quot;, is taken from a very restricted menu of message templates accompanying question closures, and might not capture too accurately what the actual misgivings of the closers are. I have a feeling that it's more like &quot;what you're asking is not useful&quot; (if you hover your mouse over the vote up/down buttons, you'll see that's one of the criteria). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It would be good if closers see this thread and could amplify further, but my guess is that the truth of the specific FLT statement is, according to current understanding, more like an epiphenomenon of deeper truths such as the modularity conjecture. Meaning that asking what ring-theoretic properties of $\mathbb{Z}$ are responsible probably doesn't reflect, to the minds of the closers, a research-level acquaintance with what is truly at stake; to put it another way, it's very likely unclear what sort of response to the question as asked could be really satisfactory to people who really understand this stuff. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Don't be too discouraged. The bar at MathOverflow is set pretty high, and it can take a while to figure out what types of questions are likely to fly. The bar is set even higher for highly notorious propositions like FLT and RH, so that any question touching on them had better be coming from someone who shows a pretty deep engagement with the underlying issues, and it looks like the question as posed doesn't quite cut it in this respect. My advice would be to aim at a level closer to where you've really done serious mathematical battle. Paraphrasing one form of advice of Polya: if there's a question you can't solve, there's probably a simpler question that you also can't quite figure out.

And a comment is (in some circumstances?) automatically posted in my name? And if the answerer has too little reputation to comment, that comment says something like &quot;This should be a comment rather than an answer.

In general, I'd say don't worry much about the workload of the moderators. Conversion to a comment takes two button clicks, and I find that on most days there aren't that many such flags that need to be dealt with. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;My main request is that the not-an-answer flag be applied reasonably accurately. As a baseline, I encourage everyone to have a look at this thread: &lt;a href=&quot;https://meta.stackexchange.com/questions/185073/how-do-i-properly-use-the-not-an-answer-flag&quot;&gt;How do I properly use the &amp;quot;Not an Answer&amp;quot; flag?&lt;/a&gt;. In particular, consider the advice of using a custom flag if you're not sure. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The meta stackexchange explanation doesn't quite address the phenomenon of (clearly) crackpot answers that fall into the &quot;not even wrong&quot; category, but I myself just about never object if such are flagged as &quot;not an answer&quot;, even if legalistically they don't fall under the stated SE criteria. Same with mathematically irrelevant responses -- most of the time, I feel those situations are tolerably clear and I'm happy to be notified of such through not-an-answer flags. But sometimes I see not-an-answer applied to items that are simply wrong, as opposed to not even wrong, and there I caution that not-an-answer is not really the right flag. Downvoting seems like a better response there. Finally, sometimes I see &quot;not an answer&quot; applied to items which seem pretty close to being an answer good and true, for example a reference to a book that looks relevant. Try to avoid that: in such cases the respondent should instead be encouraged to flesh out a more informative and self-contained answer. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A final note: most of the time I view the users who spend a lot of time going through the review queues as very helpful in moderation activity, so thanks! There are occasions where I feel some users rush to judgment too quickly, and these situations can be time-consuming deciding how to deal with, so as a general rule I ask everyone to please be careful handling questions and answers outside your range of expertise. &lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="-1" LastEditDate="2017-03-20T10:31:57.100" LastActivityDate="2017-02-19T05:26:27.903" CommentCount="2" ContentLicense="CC BY-SA 3.0" />

There are a number of issues that have been brought up, both in the post and in comments, that might be useful to tease apart. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Let me start with re-tagging. I can see why you or anyone might resent others fiddling with their tags, and I do think it would be more collegial if others would (before eliminating a tag) ask first the reasons behind it. I'll qualify that slightly: if a noob comes in with a question about high-school level analytic geometry and applies the tag algebraic-geometry, then of course it means he doesn't know what that tag means to our community, and there doesn't seem to be a real need to discuss what he is thinking. But for someone with over 1000 points of reputation, and who holds a PhD in mathematics to boot, etc.: I'd say she should be asked first before removing a tag. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(&lt;em&gt;Adding&lt;/em&gt; tags is probably less of an 'affront', although a polite comment such as &quot;I took the liberty of adding such-and-such tag; hope you don't mind&quot; would still be a nice collegial thing to do.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;That said, it's fine if someone who doesn't understand the point of a tag asks about it, and I don't agree tagging is (merely) subjective. Tags should be applied keeping in mind those users who filter by tag. Are those users likely to see the question as relevant and on-topic for that tag? If they don't, then they might feel their time has been wasted. (Let me put that more strongly: it is beyond dispute that many users are considerably annoyed by what they deem as improper tag choices -- why, there are two flags about precisely that in the moderator inbox, now as I speak.) So with that in mind, it should be part of one's routine to provide enough background so that hopefully all tags make sense to those concerned -- in particular, for a question ostensibly about transcendental number theory, some explanation for a tag like set-theory should be given. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;This ties into the general issue of motivating and providing background for questions. I think a lot of users (not speaking particularly to you, Erin, but to people out there) might be a little uptight about this: MathOverflow seems like a hard-core or austere site, and people may feel they have to make their questions very concise and constrained (sometimes very formal as well), and they wind up not sharing why the question is actually important to them. So if for example &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;usually I am thinking of something more and I just want a reliable resource for my little question &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;then please consider instead sharing a bit of that &quot;something more&quot;, if you can. If for example you intuit a connection between a question in transcendental number theory and issues related to set theory and forcing, then maybe say something about that if you can; people might find it interesting. (As an aside, Paul Cohen once said this: as a young student he was interested in number-theoretic identities like the Rogers-Ramanujan identity, and wanted to try a logical approach to them, by making an inductive analysis on the complexity of statements. &quot;In a remarkable twist this crude idea was to resurface later in the method of &quot;forcing&quot; that I invented in my proof of the independence of the continuum hypothesis&quot; -- More Mathematical People, page 50.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In any event, I remember (now ex-)user quid pressing the importance of laying out background and motivation for MO questions, and I agree, and think it might help create more positive experiences at MO. The Help page also mentions this. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;This enters into a more general question, which is sort of how I'd like the question of the OP recast, and which all of us should anyway ask ourselves: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;How can I make sure my questions are positively received? &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;To begin with something simple: rendering formulas in TeX, as Andy Putman mentioned, is the norm and expectation in our Community. It's not a hard-and-fast rule by any means. But to state something obvious: if I take pains over the presentation of my question, giving it a professional appearance, then I transmit the idea that this question is important to me and I want others to take it seriously. Thus I agree it's a good idea to make use of the TeX software, routinely. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Relatedly, there is some expectation here that people, in addition to taking care over the presentation of the question, also exercise due diligence in researching the question a little beforehand (using Google, Wikipedia, etc.) -- and indications this has been done are usually well-received. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Speaking of this: if someone comments by giving a bare Wikipedia link, then in the first place let's grant the benefit of the doubt that he probably is trying to be helpful (and not snarky or sarcastic, unless he makes that plain). But in the second place it &lt;em&gt;might&lt;/em&gt; mean he wonders why the answer wasn't found in Wikipedia, or why WP wasn't enough. Actually, not a few MO commentary discussions follow a pattern like this: a WP link is given, and the OP comes back and says, &quot;Thanks. I did see that WP article, but I don't see how it quite answers my question, because...&quot;. And that would be a good response. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(On the other hand, I think it might help too, from the standpoint of netiquette, if commenters gave a little more than a bare Wikipedia link. There is every possibility that such comes across as a little curt or dismissive, or a slam dunk, or something like that -- even if you don't mean that. Imagine a friend asking the question; you might say something simple like &quot;Might this be relevant?

There will never be complete agreement about that. Looking at the number theory question in particular, I do think Mathematics StackExchange is the better choice. (&lt;em&gt;And therefore&lt;/em&gt; the question should not be left up at MO -- one site per question, please.) Certainly it got a happier reception and result at Math.SE, and I'm glad you decided to post there. Something that worries me is that MO users may think Math.SE is a lesser site and are averse to posting there. I'd like them to reconsider. In theory there is usually a best SE site to post, and it's independent of where a user happens to feel most at home. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Looking at the beginning of your post, Erin: if it's really true that you feel put down by the responses every time you post a question, then I'm not sure what to say, except that (1) I'm concerned, and (2) I think you should consider making contact with the moderator team directly about this. Normally these things should be dealt with on a specific case-by-case basis, and not allowed to fester. Please also feel free to make use of the flag system if you think someone is being rude. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;My greatest concern of all was touched upon in Stefan Kohl's answer: that your experience may have something to do with cultural attitudes and reactions towards women mathematicians. I take that possibility seriously. (We discussed this once at 'tea' [thanks to Carlo Beenakker for tracking this down], and Izabella Laba also has some &lt;a href=&quot;https://ilaba.wordpress.com/2011/03/28/why-im-not-on-mathoverflow/&quot; rel=&quot;nofollow noreferrer&quot;&gt;thoughts on this&lt;/a&gt; at her blog.)

To make things even more infuriating, the poster answered my comment before deleting the question, so I got a reply notification, which disappeared as soon as I clicked on it, leading me to the 404 page saying the question was gone, and now I can't read that answer either (I just got a glimpse of it).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Even though I'm tempted to do so, it's probably not appropriate to repost the question, considering that I have an answer, just to ask if somebody has a &quot;better&quot; one.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;And of course &lt;a href=&quot;https://meta.stackexchange.com/questions/57537/how-do-i-contact-other-users&quot;&gt;there is no way to contact other users&lt;/a&gt; in StackExchange, which really adds insult to injury.

But I wanted to add that some of the OP's concerns may be related to structural weaknesses in the stack exchange platform itself which emerge as a site scales up.  There are three factors in play:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;Positive and negative feedback are asymmetric.  There are many ways to provide feedback which can at least be perceived as critical: down vote, critical comments, modify the question, vote to close, and flag for moderators all come to mind.  But the only way to provide positive feedback is to up vote (or leave &quot;Nice question!&quot; as a comment, which not too many people do).&lt;/li&gt;&#xA;&lt;li&gt;Privileges do not scale with the age or size of the community.  More and more people get 2k rep, and all of them can edit questions and answers.&lt;/li&gt;&#xA;&lt;li&gt;Questions and answers with a high number of up votes are emphasized by the system and thus attract a lot of attention.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;You can probably see how these three observations interact to make the experiences that the OP describes more common and more severe.  Good questions attract more attention, more attention increases the expected number of people who see the question and don't like something about it, and those people are more likely than they used to be to have powerful ways to express their criticism.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Stack Overflow today embodies these dynamics taken to their extreme.  A great many of the highest voted (and frankly most useful) questions on that site are closed as off topic, and the reason is that when thousands of highly empowered users encounter any conceivable question it is almost inevitable that five of them will eventually vote to close, and there is no offsetting &quot;vote to keep open&quot; option.  &lt;a href=&quot;https://meta.stackoverflow.com/questions/251758/why-is-stack-overflow-so-negative-of-late&quot;&gt;This question&lt;/a&gt; on Stack Overflow meta could be a cautionary tale for Math Overflow, though I think we can all agree that things aren't anywhere near as bad here as it was even two years ago there.  (They are not helped by the fact that people have professional incentives to gain reputation on Stack Overflow.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I've learned to build all of this into my prior expectations when using the stack exchange network in general - when I post a question which gets edited or attracts some critical feedback I take it in part as a positive sign that the question was interesting enough to attract attention.  And actually this is often in the spirit that the edits or critical remarks were intended: while I don't edit questions very often, when I do so it is usually because I think the question is interesting and I want to maximize the chances it will receive good answers.  This works for me, but I'm not sure it is the basis for a good long term strategy to grow and maintain the community.&lt;/p&gt;&#xA;" OwnerUserId="4362" LastActivityDate="2017-04-02T10:54:53.697" CommentCount="9" ContentLicense="CC BY-SA 3.0" />

(Unregistered users &lt;em&gt;still can answers questions&lt;/em&gt; and make edit suggestions.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I do not have any data which could quantify to which extent closed/deleted questions on MathOverflow are posted more often by unregistered users. (And I do not know whether and how such data can be obtained.&lt;sup&gt;1,2,3,4&lt;/sup&gt;) However, judging by the off-topic questions I have seen, this is quite often the case.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I suppose that users who did not bother to read in the help center what is and isn't on-topic on this site, are more likely to choose a site which does not require registration.

(At least the ones coming from unregistered users.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course, there might be also negative consequences to this change. Maybe som unregistered users will simply post their questions as answers.

Would this help to decrease frequency of off-topic questions? What are possible negative consequences?&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;There is currently one user which is a moderator on both sites. The mods have access to some data and tools which regular users do not have - perhaps moderators from Math.SE are able to assess to which extent this change helped. And moderators from MO might be able to say to which extent this really is a problem.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;Some analysis concerning number of closed questions after joining the Stack Exchange network was done here: &lt;a href=&quot;https://meta.mathoverflow.net/questions/302/has-the-switch-to-se-2-0-increased-the-rate-of-low-level-inappropriate-questio&quot;&gt;Has the switch to SE 2.0 increased the rate of low-level / inappropriate questions?&lt;/a&gt; However, in this case it is more interesting to know to which extent &lt;em&gt;unregistered users&lt;/em&gt; contribute to the closed questions.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;3&lt;/sup&gt; Based on &lt;a href=&quot;https://meta.stackexchange.com/questions/89909/stack-exchange-community-statistics/91927#comment247281_91927&quot;&gt;the comments here&lt;/a&gt; it seems that such data cannot be obtained from &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;SEDE&lt;/a&gt;. Some statistics on this were made for StackOverflow in 2011, about the time when SO started to require registration for asking questions: &lt;a href=&quot;https://meta.stackexchange.com/questions/133117/stack-exchange-community-statistics-results-in-which-ways-do-unregistered-users&quot;&gt;Stack Exchange Community Statistics results: In which ways do unregistered users participate?&lt;/a&gt; Looking at the results there, unregistered users were responsible for more than 10% of questions (before adding requirement to register) and about 3-4% of answers. However, it's hard to say to which extent behavior of users on MO and SO might be similar.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;4&lt;/sup&gt;In the absence of better data, we can simply look at the questions posted yesterday. This is a very small data sample - on the other hand, the period is short enough so that this will probably not be influenced too much by the questions which have been deleted in the meantime. (Users with &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;access to moderation tools&lt;/a&gt; can check whether there are many recent deletions.

The problem should not be viewed as an influx of bad questions to be stemmed by additional requirements on the user before they ask the question.  Instead, consider how to train this user to become a contributing community member, partly by showing them what a better version of their question would be.  In many cases, this might be redirecting them to a different forum, but in some cases it might be better to edit, answer and include links to related and more appropriate questions. Perhaps a generalized notion of duplicate would apply, so that future questioners might be given an answer before they submit their question.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think requiring registration will not be effective for dealing with (my version of) the stated problem.

Existence of this feature request suggests that you are probably not the only person who searched for information on favorites unsuccessfully in the help center.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Very briefly: If you favorite a question (=if you click on the star next to it), then it is added to &lt;a href=&quot;https://mathoverflow.net/users/current?tab=favorites&quot;&gt;your favorites tab&lt;/a&gt;. The number near this star shows how many users favorited the particular question.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So basically all it does is that it helps you to create a list of questions which you want to have accessible somewhere and where you are able to follow relatively easily whether there has been any new activity (edits, new answers, new comments). So perhaps reasonable names for this feature could also be &lt;em&gt;follow&lt;/em&gt; or &lt;em&gt;bookmark&lt;/em&gt;, rather than favorite.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;More often than not the users favorite question which are interesting to them. So typically the questions which are favorited by many users are good and interesting questions. It seems that you are asking mainly why some users favorite low quality questions. There might be many reasons for this. Some examples I can think of:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;I voted to close this question, since it was unclear/low quality. If the user edits the question, I want to see that there were changes, so that I can vote to reopen if it was sufficiently improved.&lt;/li&gt;&#xA;&lt;li&gt;I downvoted the question - if the OP edits the question, I might remove my downvote. I favorited it so that I notice any changes.&lt;/li&gt;&#xA;&lt;li&gt;The question is poor, but one the answers contains information which is interesting to me. I want to keep the link somewhere, so I add it to my favorites.&lt;/li&gt;&#xA;&lt;li&gt;The question is likely to be deleted, which makes finding it again difficult. Since I want to keep the link because of rather interesting exchange in comments, I favorite the question.&lt;sup&gt;1&lt;/sup&gt; &lt;/li&gt;&#xA;&lt;li&gt;This question is rather easy, but it suggests a generalization which seems rather intriguing to me. At the moment I do not have too much time to think about this - I will favorite the question, so that when I check my favorites, I am reminded about this.&lt;/li&gt;&#xA;&lt;li&gt;This question is so poor that it definitely should be downvoted. I have already used all my 40 votes today, so I'll mark it and get back to it tomorrow. &lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I think that this post is worth editing. But since it is advised &lt;a href=&quot;https://meta.mathoverflow.net/questions/599/do-we-have-an-unofficial-quota-on-how-many-old-questions-one-should-bump-for-min&quot;&gt;not to bump too many posts at the same time&lt;/a&gt;, I decide to do that later. So I want to mark the post somewhere. Favoriting the question is a possible a way to do this.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;Deleted questions are still shown on favorite tab - but if I remember correctly, they are displayed only to the users who are allowed to view them. Which means that the OP sees their own questions among favorites, even if they were deleted. And &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;10k+ users&lt;/a&gt; can see in this tab all deleted question they favorited. I have just favorited a few questions which seem likely to be deleted just to test this. (If you look in &lt;a href=&quot;https://mathoverflow.net/users/8250/martin-sleziak?tab=favorites&quot;&gt;my favorite tab&lt;/a&gt; and you are 10k+ user, you should see some deleted questions there. As I am below 10k, I only see those which are not deleted.)&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;If you look at answers to the questions&#xA;&lt;a href=&quot;https://math.meta.stackexchange.com/q/25295&quot;&gt;Why favorite but not upvote?&lt;/a&gt; and &lt;a href=&quot;https://math.meta.stackexchange.com/q/12297&quot;&gt;Would you ever favourite a question you down vote?&lt;/a&gt; on meta.math.SE, you will find some suggestions along similar lines. Various categories mentioned in this feature request on main meta can also give insight on how various users use favorites: &lt;a href=&quot;https://meta.stackexchange.com/q/75944&quot;&gt;Favorites improvements - search, categorize, personal tags, add note, favorite answer&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt; &#xA;&#xA;&lt;p&gt;So that it is easier to examine low quality questions which are favorited (if somebody wants to), I have created these &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;SEDE&lt;/a&gt; queries: &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/671512/questions-which-are-closed-and-favorited&quot; rel=&quot;nofollow noreferrer&quot;&gt;Questions which are closed and favorited&lt;/a&gt;, &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/671803/questions-with-negative-score-which-are-favorited&quot; rel=&quot;nofollow noreferrer&quot;&gt;Questions with negative score which are favorited&lt;/a&gt;&#xA;&lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/671513/closed-question-with-negative-score-which-are-favorited&quot; rel=&quot;nofollow noreferrer&quot;&gt;Closed questions with negative score which are favorited&lt;/a&gt;. (And it should not be difficult to create other minor variations of these queries.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In the cases where the question is favorited by single user, it might be the OP. Here is a SEDE query: &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/671530/closed-questions-with-negative-score-favorited-only-by-the-op&quot; rel=&quot;nofollow noreferrer&quot;&gt;Closed questions with negative score favorited only by the OP&lt;/a&gt;. If it is a relatively new and inexperienced user, it is quite plausible that sometimes they favorite their own question without really knowing what they are doing and how the favorites work. Another possible explanation is that if the OP sees that their question might be deleted, they can still keep the link to the question in this way.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2017-05-28T08:48:54.107" LastActivityDate="2017-05-28T08:48:54.107" CommentCount="3" ContentLicense="CC BY-SA 3.0" />

Especially with collaborative editing, I think MathOverflow could be that resource.  I would like to see more discussion on how to revise questions and the system so that a) questions and posts could be morphed into a style convenient for such &quot;random graph walk&quot; type of perusal/research, and b) the morphing process is made accessible to those studying how knowledge representation changes over time. (I think the present system does not emphasize considerations a and b.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I would hope that all questions with an honest attempt at achieving the mission of this forum could be guided toward being transformed into ideal questions.

Sometimes merging a tag into &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot;&gt;tag-removed&lt;/a&gt; is used to effectively remove some tag without bumping. (Although the questions tagged originally with the deprecated tag will still have (tag-removed) tag, at least the deprecated tag is no longer offered to users asking new questions.) So this is another possibility how a tag can be removed.&lt;sup&gt;1&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have seen that some deprecated tags have been not replaced by (tag-removed).&lt;sup&gt;2&lt;/sup&gt; I assume that this is in situations where it is preferable to remove the tag manually, because replacement by (tag-removed) could lead to many questions which are mistagged. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Ideally, the deprecated tags are going to be eventually removed. (Although this might not be realistic if the tag contains too many questions.) I understand that going through many old questions and editing them simply to remove a tag would not be ideal. But sometimes a deprecated tag is used in a new question. Or an older question is bumped for other reasons.&lt;sup&gt;3&lt;/sup&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;What is correct way to handle such posts? Is removing deprecated tag - perhaps with tag summary or comment explaining why - reasonable way to go?

The &lt;a href=&quot;https://mathoverflow.net/help/privileges/flag-posts&quot;&gt;help on flags&lt;/a&gt; explicitly says: &amp;quot;Many flags are handled by other members of the site like yourself, who've earned review privileges. Close flags, Not an Answer, and Very Low Quality are primarily handled this way.&amp;quot;&lt;/p&gt;&#xA;&lt;p&gt;And even the flags which are handled by moderators do not get to their &lt;em&gt;mailboxes&lt;/em&gt;, but I assume you were talking figuratively in the question.&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;When you flag a post as low quality or should be closed, it enters a &lt;a href=&quot;https://meta.stackexchange.com/questions/161390/what-are-the-review-queues-and-how-do-they-work&quot;&gt;review queue&lt;/a&gt; where other users vote what happens with the post next.&lt;/p&gt;&#xA;&lt;p&gt;Low quality flag sends a question into the &lt;a href=&quot;https://mathoverflow.net/review/low-quality-posts/&quot;&gt;low quality posts review queue&lt;/a&gt;. For questions which enter this review queue, &lt;a href=&quot;https://mathoverflow.net/help/privileges/edit&quot;&gt;2k+ users&lt;/a&gt; can choose from the option Looks OK, Edit, Close (or Recommend Close). For answers the last option is Delete (or Recommend Deletion) instead.&lt;/p&gt;&#xA;&lt;p&gt;If you choose &lt;em&gt;should be closed&lt;/em&gt; flag, the question enters the &lt;a href=&quot;https://mathoverflow.net/review/close/&quot;&gt;close votes review queue&lt;/a&gt;. In this review queue, &lt;a href=&quot;https://mathoverflow.net/help/privileges/close-questions&quot;&gt;3k+ users&lt;/a&gt; can choose between the options Edit, Leave Open, Close. (As already mentioned in the comment, for users with &lt;a href=&quot;https://mathoverflow.net/help/privileges/close-questions&quot;&gt;privilege to cast close votes&lt;/a&gt;, there is no actual difference between this type of flag and casting a close vote. A flag is automatically &lt;a href=&quot;https://math.meta.stackexchange.com/questions/21547/what-is-the-difference-between-voting-to-close-as-a-duplicate-and-flagging-as-a#21548&quot;&gt;converted to a close vote&lt;/a&gt;. However, a close vote pushes the question into the review queue, too.)&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;Since the OP asks also how much work flags add to reviewers (or moderators) I will add that you can get at least some idea from the review history (available to users with sufficient reputation) or from today's stats (which are shown to all users). Here is a link to &lt;a href=&quot;https://mathoverflow.net/review/close/history&quot;&gt;review history&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/review/close/stats&quot;&gt;review stats&lt;/a&gt; for close votes review. And here is &lt;a href=&quot;https://mathoverflow.net/review/low-quality-posts/history&quot;&gt;review history&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/review/low-quality-posts/stats&quot;&gt;review stats&lt;/a&gt; for low quality posts review.&lt;/p&gt;&#xA;&lt;p&gt;For the benefit of users who (like me) do not have access to the review history, I will list here the most recent low quality posts and close votes reviews. I hope I did not miss some of them. I covered at least the last 24 hours. (I checked reviews with ids starting with 82871 until now. The most recent one I found was 82950.) It is perhaps not very surprising that in the period I checked I found much more close votes reviews than low quality posts reviews.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Close vote reviews:&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82876&quot;&gt;82876&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82877&quot;&gt;82877&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82880&quot;&gt;82880&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82881&quot;&gt;82881&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82883&quot;&gt;82883&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82893&quot;&gt;82893&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82903&quot;&gt;82903&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82905&quot;&gt;82905&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82907&quot;&gt;82907&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82911&quot;&gt;82911&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82912&quot;&gt;82912&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82913&quot;&gt;82913&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82917&quot;&gt;82917&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82919&quot;&gt;82919&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82921&quot;&gt;82921&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82922&quot;&gt;82922&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82925&quot;&gt;82925&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82928&quot;&gt;82928&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82932&quot;&gt;82932&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82937&quot;&gt;82937&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82939&quot;&gt;82939&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82940&quot;&gt;82940&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82942&quot;&gt;82942&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82946&quot;&gt;82946&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82948&quot;&gt;82948&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/review/close/82950&quot;&gt;82950&lt;/a&gt;.

This question/answer is unlikely to be salvageable through editing, and might need to be removed.&amp;quot;&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;I will add that for posts which are bad enough to consider a low quality flag, users with sufficient reputation might also consider  voting to delete. (The reputation needed is &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;10k for questions&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/help/privileges/trusted-user&quot;&gt;20k for answers&lt;/a&gt;.) Posts which meet some criteria are &lt;a href=&quot;https://mathoverflow.net/help/roomba&quot;&gt;automatically deleted by a system after a certain time&lt;/a&gt;, but sometimes it makes sense to vote to delete manually. In fact, there already have been some related discussions on this meta: &lt;a href=&quot;https://meta.mathoverflow.net/questions/134/proposal-to-more-aggressively-delete-off-topic-questions&quot;&gt;Proposal to more aggressively delete off-topic questions&lt;/a&gt; or &lt;a href=&quot;https://meta.mathoverflow.net/questions/2232/should-we-try-to-re-start-manual-deletions-or-is-the-situation-fine-anyway&quot;&gt;Should we try to re-start manual deletions or is the situation fine anyway?&lt;/a&gt; Still, I think that it might be useful to leave some time so that the feedback on why the post was closed actually reaches the OP.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2022-05-29T09:00:57.547" LastActivityDate="2022-05-29T09:00:57.547" CommentCount="3" ContentLicense="CC BY-SA 4.0" />

It is not possible to edit a deleted question. But you could still edit a deleted answer. (Of course, you have to keep the link somewhere, so that you find the deleted post. If the question is not deleted, editing an answer causes question to be bumped. But if the question is deleted too, you do not upset anybody by bumping.) However, this is not how deleted posts are supposed to be used. I am not sure to which extent this is &lt;em&gt;bad&lt;/em&gt;. (But I do not consider it very likely that this could lead to a ban, at least not without some previous warning.) For further discussion see: &lt;a href=&quot;https://math.meta.stackexchange.com/q/23285&quot;&gt;Would using deleted (“hidden”) questions on math.SE for personal use be considered misuse of the site?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;It would probably be better to do this &lt;em&gt;externally&lt;/em&gt;:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Personally, I often simply store drafts of posts on my hard drive. I do not have preview, but I think that I am familiar both with &lt;a href=&quot;https://meta.mathoverflow.net/tags/mathjax/info&quot;&gt;MathJax&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/tags/markdown/info&quot;&gt;Markdown&lt;/a&gt; enough to be able to prepare a post without need of preview. And in this way I can use my favorite editor. (With all keyboard shortcuts I am used to and whatnot.)&lt;/li&gt;&#xA;&lt;li&gt;If you want to have also preview, you can use some editor which supports MathJax and Markdown. Some such editors were mentioned here: &lt;a href=&quot;https://math.meta.stackexchange.com/q/4735&quot;&gt;MathJax: better way to prepare a Math.StackExchange question?&lt;/a&gt; For example, &lt;a href=&quot;https://stackedit.io/&quot; rel=&quot;nofollow noreferrer&quot;&gt;StackEdit&lt;/a&gt; was &lt;a href=&quot;https://meta.mathoverflow.net/q/55#857&quot;&gt;recommended by François G.

In the case of Math.SE, my understanding is that questions that look like homework (the linked question could very well be an example) and that don't give indication that the OP put much thought or effort into it are generally not well-received there. In such cases it's better just to point to Math.SE as a better place for such questions than MO, thus giving the OP a chance to adapt the question before posting it there.

That includes the snippet editor on SO, the citation helper here, and basically all other custom editor buttons on any SE sites.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(If you notice any such buttons working on a touchscreen device, that probably means that the code that &lt;em&gt;tries&lt;/em&gt; to disable them fails to work on that device for some reason.  One possible explanation could be that your browser is configured not to actually generate touch events, and thus the SE editor cannot tell that it's running on a touchscreen device.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Anyway, my &lt;a href=&quot;https://stackapps.com/questions/4486/the-stack-overflow-unofficial-patch-soup&quot;&gt;SOUP&lt;/a&gt; user script / browser extension contains a client-side hack to work around this restriction, although it's currently only included in the experimental development version.  Once I get around to releasing the next stable version of SOUP, you could install it on your touch device, assuming that your browser actually supports user scripts or can run SOUP as an extension.  (Unfortunately, most mobile browsers don't. &#xA; I've tested the SOUP Firefox extension on Firefox Mobile, though, and it appears to run fine there.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course, user scripts like SOUP can't actually fix the root cause of such bugs, they just hide the problem from those few users motivated enough to install them.  A proper solution would be for Stack Exchange developers to fix the Markdown editor code so that custom editor buttons aren't needlessly disabled on touch devices.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Ps. It does occur to me that MO is a bit of a special case, since &lt;a href=&quot;https://meta.mathoverflow.net/questions/969/who-owns-mathoverflow/970#970&quot;&gt;you're allowed to include custom JS on the site&lt;/a&gt;.  Thus, in principle, you could use that feature to hack around the unnecessary touch device check, and so enable the citation helper on mobile devices.  Just as an illustrative example, here's some (only briefly tested!) JS code that should achieve this:&lt;/p&gt;&#xA;&#xA;&lt;pre&gt;&lt;code&gt;// hook the Markdown editor code to let the citation helper work on touch devices&#xA;StackExchange.ifUsing('editor', function () {&#xA;    StackExchange.MarkdownEditor.creationCallbacks.add(function (editor, postfix) {&#xA;        $('#post-editor' + postfix).on(&#xA;            'touchstart', '.wmd-cite-button &amp;gt; span',&#xA;            function () { $(this).off('touchend') }&#xA;        );&#xA;    });&#xA;});&#xA;// just in case, also fix any editor instances that have already been initialized&#xA;$('.post-editor').on(&#xA;    'touchstart', '.wmd-cite-button &amp;gt; span',&#xA;    function () { $(this).off('touchend') }&#xA;);&#xA;&lt;/code&gt;&lt;/pre&gt;&#xA;&#xA;&lt;p&gt;This is based on the code I'm currently using in SOUP, but somewhat streamlined to only do the bare minimum needed to enable the citation helper on touch devices.  (The SOUP code also fixes the SO snippet editor, which is somewhat more complicated.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course, if you were to actually submit this code to SE for inclusion in the custom JS footer, my guess is they'd just get somebody to fix this bug properly instead.

And I edit such links when I spot them. (This basically amounts to correcting a &quot;broken&quot; link, which I consider an improvement of a post.) Usually all you do is to omit the part which contains the university proxy and you get a working link.

A natural guess is that link should work after removing the &lt;code&gt;ezlibproxy1.ntu.edu.sg&lt;/code&gt; part to get &lt;a href=&quot;http://www.ams.org/mathscinet/search/publdoc.html?arg3=&amp;amp;co4=AND&amp;amp;co5=AND&amp;amp;co6=AND&amp;amp;co7=AND&amp;amp;dr=all&amp;amp;pg4=AUCN&amp;amp;pg5=TI&amp;amp;pg6=PC&amp;amp;pg7=ALLF&amp;amp;pg8=ET&amp;amp;review_format=html&amp;amp;s4=Habiro&amp;amp;s5=claspers&amp;amp;s6=&amp;amp;s7=&amp;amp;s8=All&amp;amp;vfpref=html&amp;amp;yearRangeFirst=&amp;amp;yearRangeSecond=&amp;amp;yrop=eq&amp;amp;r=2&amp;amp;mx-pid=1735632&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://www.ams.org/mathscinet/search/publdoc.html?arg3=&amp;amp;co4=AND&amp;amp;co5=AND&amp;amp;co6=AND&amp;amp;co7=AND&amp;amp;dr=all&amp;amp;pg4=AUCN&amp;amp;pg5=TI&amp;amp;pg6=PC&amp;amp;pg7=ALLF&amp;amp;pg8=ET&amp;amp;review_format=html&amp;amp;s4=Habiro&amp;amp;s5=claspers&amp;amp;s6=&amp;amp;s7=&amp;amp;s8=All&amp;amp;vfpref=html&amp;amp;yearRangeFirst=&amp;amp;yearRangeSecond=&amp;amp;yrop=eq&amp;amp;r=2&amp;amp;mx-pid=1735632&lt;/a&gt;.

Should I expect that somebody with MathSciNet access will check the link if I am unable to? Should I explicitly ask somewhere (perhaps &lt;a href=&quot;https://chat.stackexchange.com/?tab=site&amp;amp;sort=active&amp;amp;host=mathoverflow.net&quot;&gt;in chat&lt;/a&gt;) whether somebody would be willing to check the link?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Of course, I am aware that this is a very minor problem.

It is obvious to me that everyone else who tried to understand this point would get stuck. I ask around, people either haven't seen the paper at all or didn't care about this particular point. I waste a lot of time, find that maybe the statement is wrong as stated, or it can be fixed in some way, or it is correct but I made a mistake. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Anyway, just having a chance to see if anyone else encountered the same problem with the same paper would be very useful to me. So I would like to have a platform to discuss papers. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;When I discuss this idea with colleagues, I find that many oppose it, mostly because of fear that it would be abused, i.e. people would push their political agenda, those who don't understand the content, but have enough influence, would be able to discredit the paper, etc. I would like to stress that I want to discuss papers from a purely technical point of view, in exactly the same way as questions on MO are asked and answered. It is not about discussing if a paper is important, or if the proofs are complete. I would like to be able to exchange ideas with other people who tried to read the same paper, in order to answer the questions I have in mind, and answer other's questions.

I did this for a couple reasons. I didn't mention these in the main question, but I also didn't intend them to be secret or anything - I thought they would be clear from context.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Given this meta question, though, I'd like to say a bit about why I downvoted, since I think this will address the question you should be asking here, namely &quot;What can I do better?&quot;&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;First&lt;/strong&gt;, the question is already somewhat unclear (and was more unclear to begin with), but more problematically attempts to clarify it haven't yielded a lot of success (and it's worth noting that both votes to close currently are as &quot;unclear&quot;). I'm still not entirely sure whether either Asaf's or my answer addresses the question you're trying to ask, although in my opinion they address the only reasonable question you could be asking here. Of course sometimes one starts with a somewhat unclear question and then finds it clarified over time, but I don't think that has happened in this case, at least not enough.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In particular, you write here:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;They should produce answers more relevant to the issues I raise.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;The answers we've produced &lt;em&gt;are directly relevant&lt;/em&gt; to the only meaningful interpretation of your question I can come up with; I genuinely don't understand what is missing from them. (Note that all this is addressing your question (i); your question (ii), meanwhile, seems to be completely answered by the observation that $\mathcal{P}$ and $\mathcal{P}_{def}$ &lt;em&gt;never&lt;/em&gt; coincide in any model of ZF, but there seems to be some confusion on this point.) If we're unable to come up with answers you think are relevant, then maybe you haven't succeeded in asking the question you want to.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Second&lt;/strong&gt;, I strongly believe that you're putting the cart before the horse: basic confusions &lt;em&gt;(e.g. the conflation between models and theories in the original formulation, confusions re: sets versus formulas defining sets, and questions like &quot;can ZF prove some sets are constructible?&quot;/&quot;can [ZF] prove that there exist constructible sets&quot; that have emerged in the comments)&lt;/em&gt; and how you've responded to them make me doubt whether, even if the question were phrased clearly, an answer can be given to you at the moment. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Even beyond that, the way you've engaged the answers and subsequent comments has left me in the dark about what you do and don't understand. Of main relevance is:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Do you understand that ZF can prove the existence of sets whose constructibility ZF cannot prove (e.g. ZF proves that $\mathcal{P}(\omega)$ exists, but cannot prove that $\mathcal{P}(\omega)$ is constructible)?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;(If you do, this takes us back to my first point: how does this not answer your question?)&lt;/em&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;And the following arises from the conversation in the comments, although it's not really directly relevant to your question:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Do you understand that, and why, we can never have $\mathcal{P}_{def}=\mathcal{P}$ in any model of ZF?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Basically, from your responses to my and Asaf's answers and the various comments, I don't think you're currently in a place where this question can be satisfactorily answered; moreover, I don't have a good enough understanding of what you do understand to help lead you in a good direction.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Finally&lt;/strong&gt;, there's the issue of your general engagement with this question (and other questions); this subsumes the previous point. What you've done here and elsewhere is try to draw your question into a larger philosophical web of ideas; the problem is that this only introduces more confusions, especially when the mathematical content of the question is already unclear. That broader web of ideas is something you can only engage &lt;em&gt;after&lt;/em&gt; developing a solid command of the basics. This is something we're happy to help with (arguably more at math.stackexchange than mathoverflow, although mathoverflow is in practice fairly forgiving for logic questions), but embedding philosophical concerns inside an unclear question, which keeps shifting its goalposts (often nonsensically) in the comments, doesn't yield a good question.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;So that's why I downvoted.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;My advice for you going forward&lt;/strong&gt; is twofold. First, ask clear questions; in particular, if you're asking a question here you should have a solid understanding of the meanings of the basic terms in that question, so there shouldn't be any unclearness resulting from basic misuse. Second, make understanding the answer to your question your priority, rather than understanding how it fits in with your philosophical conceptions. These are two different tasks, and it's my experience that your eagerness to do the latter gets in the way of you doing the former. &lt;/p&gt;&#xA;" OwnerUserId="8133" LastActivityDate="2017-08-25T22:50:12.900" CommentCount="14" ContentLicense="CC BY-SA 3.0" />

(And the fact that several newer sites do not have their own twitterbots is a supporting evidence.)&lt;/s&gt; Mad Scientist &lt;a href=&quot;https://meta.mathoverflow.net/questions/3367/mo-twitter-presence#comment14863_3369&quot;&gt;added in a comment&lt;/a&gt; link to an answer on meta.SE related which mentions reasons for this decision: &lt;a href=&quot;https://meta.stackexchange.com/q/264547#264548&quot;&gt;Why is it so difficult to find the twitter account for a Stack Exchange site?&lt;/a&gt; I will quote this part: &quot;Twitter-the-company started blocking new accounts for us (probably because it thinks we're bots?) and fighting that got too annoying and time-consuming.&quot; (This is probably useful to know for anybody who considers starting some twitter account where posting of tweets based on the content of MO would be - in some way - automated.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you want to learn more about these twitter bots, the &lt;a href=&quot;https://meta.stackexchange.com/questions/tagged/twitter&quot;&gt;tag twitter on meta.SE&lt;/a&gt; seems to be the right place to go.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;To me this seems as the &quot;cheapest&quot; option. There already is existing infrastructure and an algorithm which selects what to tweet. So it would probably not be too much work to add this also for MO. (However, since these twitter bots are no longer supported - one of the main reasons might be the problems mentioned above - I am not sure whether SE staff would be willing to do this.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;EDIT: Probably it's worth adding that there are some SE sites that have a twitter account which is run by community, i.e., tweets are added manually and not by bots. There are two such sites that I am aware of: Literature Stack Exchange (&lt;a href=&quot;https://twitter.com/StackLiterature&quot; rel=&quot;nofollow noreferrer&quot;&gt;twitter account&lt;/a&gt; and &lt;a href=&quot;https://literature.meta.stackexchange.com/questions/689/literature-now-has-a-community-maintained-twitter-account&quot;&gt;announcement on meta&lt;/a&gt;) and Mi Yodeya (&lt;a href=&quot;https://twitter.com/mi_yodeya&quot; rel=&quot;nofollow noreferrer&quot;&gt;twitter account&lt;/a&gt; and &lt;a href=&quot;https://judaism.meta.stackexchange.com/questions/1798/mi-yodeya-is-people&quot;&gt;announcement on meta&lt;/a&gt;).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Which questions to tweet&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Several possibilities how to choose questions which should be tweeted have been mentioned.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;As I wrote above, twitterbots for other sites already have some algorithm how to choose questions.&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://meta.stackexchange.com/tags/hot-questions/info&quot;&gt;Hot network questions&lt;/a&gt; were suggested as a possibility by the OP. I'll just point out that questions with MathJax in the title &lt;a href=&quot;https://meta.stackexchange.com/q/237475&quot;&gt; are never chosen in the HNQ&lt;/a&gt;. Still, I guess it is possible to calculate for such questions &lt;a href=&quot;https://meta.stackexchange.com/q/11602&quot;&gt;whether question is hot or not&lt;/a&gt; (they are just not picked in the networkwide list.)&lt;/li&gt;&#xA;&lt;li&gt;Some other possibilities would be choosing questions similarly as in the &lt;a href=&quot;https://meta.stackexchange.com/tags/newsletter/info&quot;&gt;newsletter&lt;/a&gt; (suggested &lt;a href=&quot;https://meta.mathoverflow.net/questions/3367/mo-twitter-presence#comment14823_3367&quot;&gt;in a comment&lt;/a&gt;). &lt;/li&gt;&#xA;&lt;li&gt;You can see questions &lt;a href=&quot;https://mathoverflow.net/questions/greatest-hits&quot;&gt;listed as greatest hits&lt;/a&gt; and questions which are &lt;a href=&quot;https://mathoverflow.net/?tab=hot&quot;&gt;currently hot&lt;/a&gt;. AFAIK the choice of these questions is related to choice of question in the newsleter and the hot network questions list.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Is MO already present on twitter?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In fact, you can see that there are already many MO-related tweets out there. You can easily find some of them by searching &lt;a href=&quot;https://www.google.com/search?q=mathoverflow+site%3Atwitter.com&quot; rel=&quot;nofollow noreferrer&quot;&gt;in Google&lt;/a&gt; or &lt;a href=&quot;https://twitter.com/search?q=mathoverflow&quot; rel=&quot;nofollow noreferrer&quot;&gt;on Twitter&lt;/a&gt; or using &lt;a href=&quot;https://twitter.com/hashtag/mathoverflow&quot; rel=&quot;nofollow noreferrer&quot;&gt;#mathoverflow&lt;/a&gt;. (You might also recognize some of usernames as users on this site.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In fact, Joel David Hamkins tweeted about &lt;a href=&quot;https://twitter.com/JDHamkins/status/901644476850032645&quot; rel=&quot;nofollow noreferrer&quot;&gt;this meta question&lt;/a&gt; (and it seems that &lt;a href=&quot;https://twitter.com/JDHamkins/&quot; rel=&quot;nofollow noreferrer&quot;&gt;he has many tweets&lt;/a&gt; related to MO posts.) See also some his comments above.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I found also two twitter accounts: &lt;a href=&quot;https://twitter.com/MathOverflow&quot; rel=&quot;nofollow noreferrer&quot;&gt;MathOverflow&lt;/a&gt; and &lt;a href=&quot;https://twitter.com/MathOverflowQs&quot; rel=&quot;nofollow noreferrer&quot;&gt;MathOverflow Feed&lt;/a&gt;. However, there was no activity on those accounts since 2011. (Creation of one of them by Anton Geraschenko is mentioned in &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/388/twitter/&quot; rel=&quot;nofollow noreferrer&quot;&gt;this tea discussion&lt;/a&gt;. I do not know about the other one.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Users who have &lt;a href=&quot;https://mathoverflow.net/help/privileges/site-analytics&quot;&gt;access to site analytics&lt;/a&gt; can see how much of the referrals are generated by twitter. (As I mentioned &lt;a href=&quot;https://meta.mathoverflow.net/questions/3367/mo-twitter-presence#comment14821_3367&quot;&gt;in my comment&lt;/a&gt;, the statistics of traffic sources &lt;a href=&quot;https://math.stackexchange.com/site-analytics/traffic-sources&quot;&gt;for math.SE&lt;/a&gt; &lt;code&gt;t.co&lt;/code&gt; is listed among referring sites with 3.4%.

(Perhaps stating clearly at the beginning that this site is for research-level questions? This information is displayed on &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;another page in the help center&lt;/a&gt;, but probably it might be worth including here, too.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Are there some other possibilities what can be chosen to be displayed as the &quot;welcome page&quot; to the user asking the first question? (I am not really sure whether it is possible to use something different that &quot;How to ask&quot; page, but if some options are suggested and if this is seriously considered, I suppose the moderators can find out from SE staff whether it is possible.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;Such questions are usually relatively quickly closed and downvoted - which means that eventually &lt;a href=&quot;https://mathoverflow.net/help/roomba&quot;&gt;roomba&lt;/a&gt; takes care of them (or the question might be deleted even sooner by &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;users with sufficient reputation&lt;/a&gt;). But still, having less such questions would mean less work for users who cast close votes or do close votes reviews. In the past some users complained about off-topic posts on the frontpage, for example: &lt;a href=&quot;https://meta.mathoverflow.net/q/1185&quot;&gt;Can the clutter of obviously off-topic questions be removed faster?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;In the comments some concerns were raised that this idea (or some variation thereof) could lead to some users losing the question they typed simply by clicking incorrect field.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;@MattF., that seems like a great idea.  The only concern I'd raise is:  would the 'wrong' answer automatically trigger rejection of the post, or just a warning that it might not be appropriate?  If the latter, then people might just ignore it as they would ToS.  If the former, then good questions could be lost to people giving overly honest answers. -- &lt;a href=&quot;https://meta.mathoverflow.net/questions/3386/should-users-be-shown-some-basic-information-before-posting-the-first-question#comment14906_3386&quot;&gt;LSpice&lt;/a&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;So I'd like to clarify that the proposal is to show How to ask page (or something similar) &lt;em&gt;before&lt;/em&gt; the user starts typing their first question. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;To check how this work on other sites, I created a completely new account on Mathematics. Immediately after creating an account, the invitation to view the tour was shown in my inbox. (However, this is easy to ignore.

There was a longish string of comments below the question, and it was closed as &quot;unclear what you're asking&quot;. If this is &lt;em&gt;not&lt;/em&gt; what you were looking for, then you had better give at least some description or keywords. &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&quot;With typical hubris I thought I had a proof of the inference rule for induction starting from a construction of the natural numbers.

I would appreciate some clarification. There are some rambling comments of mine at the end but I'm not sure these are of much value.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&quot;&lt;strong&gt;Update:&lt;/strong&gt; There is a rather glib answer to the remaining question, namely is &lt;code&gt;τ(s(k))=σ,T(k)::P(k)&lt;/code&gt; correct? The answer is that if &lt;code&gt;τ(s(k))&lt;/code&gt; were not defined in this way then theorem &lt;code&gt;T(s(k))&lt;/code&gt; would simply not verify.&quot; &lt;/p&gt;&#xA;" OwnerUserId="2926" LastActivityDate="2017-09-19T13:04:00.117" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

It works for &lt;a href=&quot;https://mathoverflow.net/users/deleted-answers/current&quot;&gt;answers&lt;/a&gt; in the same way. (This used to work differently - see the next bullet point. It was changed in January 2022.&lt;sup&gt;1&lt;/sup&gt;)&lt;/li&gt;&#xA;&lt;li&gt;&lt;s&gt;At the bottom of &lt;a href=&quot;https://mathoverflow.net/users/current?tab=questions&quot;&gt;the question tab in your profile&lt;/a&gt; you can click on deleted recent questions. In this way you get all your deleted questions which are not too old. (To be more precise, the deleted questions which were created during the last 60 days. More details: &lt;a href=&quot;https://meta.stackexchange.com/q/185491&quot;&gt;What is the 'deleted recent questions' page in the user profile?&lt;/a&gt;)&lt;/s&gt;&lt;/li&gt;&#xA;&lt;li&gt;If you have &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;at least 10k reputation&lt;/a&gt; you can search among all &lt;em&gt;your&lt;/em&gt; deleted posts using the operator &lt;a href=&quot;https://mathoverflow.net/search?q=deleted%3A1&quot;&gt;deleted:1&lt;/a&gt;. For example, &lt;a href=&quot;https://mathoverflow.net/search?q=deleted%3A1+is:q&quot;&gt;deleted:1 is:q&lt;/a&gt; returns (for a 10k+ user) list of &lt;em&gt;their own&lt;/em&gt; deleted questions. (And you can use also other search modifiers.)&lt;sup&gt;2&lt;/sup&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;See the section &amp;quot;Can I see a list of my deleted posts?&amp;quot; in the FAQ post: &lt;a href=&quot;https://meta.stackexchange.com/q/5221&quot;&gt;How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion?&lt;/a&gt;. And also some other related posts, such as: &lt;a href=&quot;https://meta.stackexchange.com/q/2645&quot;&gt;Show all of my question/answers to me even if they are deleted&lt;/a&gt;,&lt;a href=&quot;https://meta.stackexchange.com/q/375071&quot;&gt;Make your deleted questions and answers more discoverable&lt;/a&gt;, &lt;a href=&quot;https://meta.stackexchange.com/q/13193&quot;&gt;We should be able to find questions or answers that we have deleted&lt;/a&gt;, &lt;a href=&quot;https://meta.stackexchange.com/q/217169&quot;&gt;How do I view my old deleted questions?&lt;/a&gt;, etc.&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;See also: &lt;a href=&quot;https://meta.stackexchange.com/q/145060&quot;&gt;Enable searching with deleted:1 for 10k users&lt;/a&gt;&lt;/p&gt;&#xA;&lt;hr&gt; &#xA;&lt;p&gt;&lt;s&gt;If the above does not help you (i.e., the question is old and you are below 10k), you might still find the link in some other way if you are lucky.&lt;/s&gt;&lt;/p&gt;&#xA;&lt;p&gt;EDIT: Now that any user can get a list of all their deleted questions (answers), this part is not really relevant if you are looking for &lt;em&gt;your own&lt;/em&gt; deleted post. I'll still leave it here - in case some of the information given here might be useful in some other situations.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;You can try checking your browser history, if you remember some part of the title.&lt;/li&gt;&#xA;&lt;li&gt;Perhaps you can find question in some lists on this site. If you favorited the question, you can still see it &lt;a href=&quot;https://mathoverflow.net/users/current?tab=favorites&quot;&gt;in your favorites&lt;/a&gt;. If you received &lt;a href=&quot;https://mathoverflow.net/users/current?tab=badges&quot;&gt;some badge&lt;/a&gt; for this particular question, you will find the question in the list of posts for which you earned the specific badge. (To display the list, just click on the badge in question.) If you deleted the question yourself, you can still find it in the &lt;a href=&quot;https://mathoverflow.net/users/current?tab=votes&amp;amp;sort=deletion&quot;&gt;list of your delete votes&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Sometimes &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;data explorer&lt;/a&gt; might help. The data are updated only once a week - it is possible that a question is deleted on the site but it is still in the database. Here is a query to find &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/731875/all-questions-by-a-given-user&quot; rel=&quot;nofollow noreferrer&quot;&gt;all questions from a specific user&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;You can also try &lt;a href=&quot;https://webapps.stackexchange.com/questions/15633/how-to-modify-a-url-to-get-a-google-cached-version-of-page&quot;&gt;Google Cache&lt;/a&gt; or &lt;a href=&quot;https://en.wikipedia.org/wiki/Wayback_Machine&quot; rel=&quot;nofollow noreferrer&quot;&gt;Wayback Machine&lt;/a&gt; to see whether you can find there some version of your profile (or list of questions in a specific tag or some other reasonable page) which still contains the question you're interested in.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;hr&gt;  &#xA;&lt;p&gt;Moderators are able to search among deleted questions. (This is different from the possibility for 10k+ users mentioned above - they can only search for &lt;em&gt;their own&lt;/em&gt; deleted posts.)&lt;/p&gt;&#xA;&lt;p&gt;So if the above fails, you can probably ask a moderator for help. Past experience here on meta suggests that they were usually willing to help with requests to find some deleted questions. (And I assume they will also be willing to do this also in the future, unless such requests become too frequent.)&lt;/p&gt;&#xA;&lt;p&gt;I will add that 10k+ users can see recent deletions - with the exception of self-deletions - in &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;moderator tools&lt;/a&gt;. But this only shows the posts which were deleted recently - this is far from searching among &lt;em&gt;all&lt;/em&gt; deleted posts as moderators can. Still, &lt;em&gt;in some cases&lt;/em&gt; any 10k+ user could be able to find your deleted question for you in this way.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2022-01-15T02:54:05.833" LastActivityDate="2022-01-15T02:54:05.833" CommentCount="2" ContentLicense="CC BY-SA 4.0" />

(The tag name is within the recently increased 35 character limit.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Looking at the main site, it seems that small uncountable cardinals (such as &lt;span class=&quot;math-container&quot;&gt;$\mathfrak p$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$\mathfrak t$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$\mathfrak b$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$\mathfrak d$&lt;/span&gt;, etc.) get quite a lot of attention on this site. For example, if you search for either of the cardinals mentioned before in the set theory tag, you can find a bunch of questions: &lt;a href=&quot;https://mathoverflow.net/search?q=&amp;quot;mathfrak+p&amp;quot;+%5Bset-theory%5D&quot;&gt;p&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/search?q=&amp;quot;mathfrak+t&amp;quot;+%5Bset-theory%5D&quot;&gt;t&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/search?q=&amp;quot;mathfrak+b&amp;quot;+%5Bset-theory%5D&quot;&gt;b&lt;/a&gt;,&#xA;&lt;a href=&quot;https://mathoverflow.net/search?q=&amp;quot;mathfrak+d&amp;quot;+%5Bset-theory%5D&quot;&gt;d&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think that creating a separate tag for this topic might made searching for such questions easier. Additionally people who are interested in the topic could follow the tag. (I.e., they could get those questions highlighted, they have easier access to recent questions &lt;a href=&quot;https://mathoverflow.net/search?tab=active&amp;amp;q=intags:mine&quot;&gt;in their favorite tags&lt;/a&gt;, etc.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course, it is possible to consider also other candidates for the name of the tag. Wikipedia uses &lt;a href=&quot;https://en.wikipedia.org/wiki/Cardinal_characteristic_of_the_continuum&quot; rel=&quot;nofollow noreferrer&quot;&gt;Cardinal characteristic of the continuum&lt;/a&gt;. (For example, cardinal-characteristic-continuum is under the 35 characters limit.)&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;It seems that in the past mostly the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/set-theory&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;set-theory&amp;#39;&quot; rel=&quot;tag&quot;&gt;set-theory&lt;/a&gt; was used for questions about this topic.

However, there is also a similar feature request on the main meta: &lt;a href=&quot;https://meta.stackexchange.com/q/1031&quot;&gt;Filter users by country&lt;/a&gt;. So there you can see how it was received and maybe eventually also some decision whether or not it is going to be implemented will be given there.&lt;/p&gt;&#xA;&lt;p&gt;Let me try to answer the &lt;a href=&quot;/questions/tagged/support&quot; class=&quot;post-tag required-tag&quot; title=&quot;show questions tagged &amp;#39;support&amp;#39;&quot; rel=&quot;tag&quot;&gt;support&lt;/a&gt; part of your question. (Which I understand as: What can be done with the existing tools without implementing new functionality?)&lt;/p&gt;&#xA;&lt;p&gt;I think that ideal tool for tasks like this is &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;Stack Exchange Data Explorer&lt;/a&gt;. (Since becoming part of SE network, &lt;a href=&quot;https://meta.mathoverflow.net/q/634&quot;&gt;MathOverflow is included in the database&lt;/a&gt;.) From the information about users &lt;a href=&quot;https://meta.stackexchange.com/q/2677&quot;&gt;available in the database&lt;/a&gt;, the Location in the Users table seems like the best choice for finding some information about country. (Of course, we will not find users which for some reason left this field blank or included something else there.)&lt;/p&gt;&#xA;&lt;p&gt;You can create your own query or use some of already existing ones.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;A rather simple approach is simply to search for country name in this field. Perhaps reasonable addition is adding also &lt;a href=&quot;https://en.wikipedia.org/wiki/Country_code&quot; rel=&quot;nofollow noreferrer&quot;&gt;country code&lt;/a&gt;. (Country codes might lead to some false positives, but you will not miss users who list their location, for example, as &amp;quot;Toronto, CA&amp;quot;.) This approach is illustrated in answers to this question: &lt;a href=&quot;https://meta.stackexchange.com/q/207650&quot;&gt;Finding Top Users by country&lt;/a&gt;. The query &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/148176/top-users-by-country?Top=100&amp;amp;FullCountryName=India&amp;amp;ShortCountryName=ind&quot; rel=&quot;nofollow noreferrer&quot;&gt;Top users by country&lt;/a&gt; is linked in one of the answers there.&lt;/li&gt;&#xA;&lt;li&gt;Depending on how much time you are willing to spend on this, you might try to create more sophisticated queries. For example, you can try to find users who included only city in the location, but not the country. (Again, this might lead to some false positivies.) The following query, that somebody created specifically for Ukraine, seems to be quite good example of this: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/157038/user-list-top-n-ukraine-with-false-positive-exclusions?Top=50&quot; rel=&quot;nofollow noreferrer&quot;&gt;User List: Top N - Ukraine- with false positive exclusions&lt;/a&gt;. Similar &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/155640/user-list-top-n-canada-with-false-positive-exclusions?Top=50&quot; rel=&quot;nofollow noreferrer&quot;&gt;query for Canada&lt;/a&gt; might serve as an example where excluding false positives needed more effort. (Judging by the comments at the end of the query, the creator might still consider this query to be unfinished.) It seems that the same user created &lt;a href=&quot;https://data.stackexchange.com/users/12448/jon-doe12449&quot; rel=&quot;nofollow noreferrer&quot;&gt;similar queries for several other countries&lt;/a&gt;. (Since the name of queries this user created seem to be similar, another way to see them is to google for &lt;a href=&quot;https://www.google.com/search?q=user+list+with+false+positive+exclusions+site%3Adata.stackexchange.com&quot; rel=&quot;nofollow noreferrer&quot;&gt;user list with false positive exclusions site:data.stackexchange.com&lt;/a&gt;.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;It goes without saying that you can find many already existing queries for searching by country &lt;a href=&quot;https://www.google.com/search?q=country+top+users+site%3Adata.stackexchange.com&quot; rel=&quot;nofollow noreferrer&quot;&gt;in general&lt;/a&gt; or from &lt;a href=&quot;https://www.google.com/search?q=top+users+from+site%3Adata.stackexchange.com&quot; rel=&quot;nofollow noreferrer&quot;&gt;one specific country&lt;/a&gt;.

I think some of this is also reflected in an interesting discussion I recently had in the MathOverflow chat room with Martin Sleziak. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;For me, some of quid's feelings came strongly to the fore in a kind of argument we once had over in the meta thread on reopening closed questions, here: &lt;a href=&quot;https://meta.mathoverflow.net/a/2564/2926&quot;&gt;https://meta.mathoverflow.net/a/2564/2926&lt;/a&gt;. The MO question we were discussing seemed, to me, to be of obvious interest to mathematicians and really spoke for itself -- &quot;needed no introduction&quot; so to speak, and hence deserved to be reopened. Quid objected that the question formulation was poor, because no motivation or context was set, and I got the strong sense that for quid this is really a sine qua non for a MO question to be good. Whether this type of issue weighed strongly in quid's decision to quit MO is not for me to say, but I do consider it a data point. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Martin Sleziak in our discussion (which got started round about here: &lt;a href=&quot;https://chat.stackexchange.com/rooms/9369/conversation/discussion-about-differences-between-mo-and-math-se&quot;&gt;https://chat.stackexchange.com/rooms/9369/conversation/discussion-about-differences-between-mo-and-math-se&lt;/a&gt;) raised my consciousness about some significant cultural differences between the two sites (I am only an occasional participant over there). It seems that one important ethos at Math.SE is to &lt;em&gt;consciously create&lt;/em&gt; a repository of knowledge, which may involve a conscious effort to &quot;tune&quot; a question so that it is not just about the questioner's immediate concerns, but includes an explanation for everyone out there that places the question broadly within mathematics and underlines its possible significance. This is obviously related to quid's line of argument at the reopening thread mentioned above. According to this ethos, answers too at Math.SE should not be directed just to the questioner (e.g. his/her current state of knowledge), but metaphorically over the head to address the wider audience out there, again with a conscious view to build a knowledge data base. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Here at MO, questions are by and large accepted based on perceived level, either as being obviously a question a research mathematician might need to ask, or as posing a challenging problem for research mathematicians. (For an example of the latter, recall &lt;a href=&quot;https://mathoverflow.net/questions/282035/is-the-sum-of-digits-of-31000-divisible-by-7&quot;&gt;Is the sum of digits of $3^{1000}$ divisible by $7$?&lt;/a&gt; -- clearly this was not a question asked by a research mathematician, but it was accepted anyway as posing a curious challenge -- I for one thought about it for ten minutes or so.) In either case questions are generally accepted on their own merits, and there is generally not a concerted effort to tune questions further to explain their broader significance unless it's really not obvious to users what their point might be. (Yes, it's true that in Help we say that the setting out context and/or motivation helps make a question good, but certainly at MO that's not &quot;enforced&quot;, or only very laxly so.) And it may be true that answers at MO are usually more in view of helping the individual questioner than of speaking to the audience out there and for the ages, so to speak -- this was also touched on in the discussion with Martin. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I wouldn't say either mode is &quot;good&quot; or &quot;bad&quot; -- MO and Math.SE are just very different beasts and appeal in different ways to different audiences. Here at MO, our quality control is mainly based on level as described above, and otherwise it's largely live and let live, granting authors a certain degree of autonomy in how they choose to ask questions. The result is that MO is a garden of limitless delight for a sophisticated audience, but maybe somewhat loosely organized (which I believe quid also publicly commented on, but I'd have to search to find it). Over at Math.SE, a different kind of quality control is called for, and I expect there is more vigorous hands-on editorship over there over question formulation. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;From the very get-go leading up to the move to join the SE network, MathOverflow has in spirit always wanted to maintain its autonomy and independence (befitting broad cultural norms of professional mathematics communities, I think): recall the discussions we've had about opting out of the network should the SE hand be felt too heavily. There is a certain level of acceptance here of the wisdom of certain SE operating principles, but I don't think we're quite as beholden to those as some of the other SE sites. Math.SE on the other hand strikes me as operating more according to the &quot;SE book&quot;, which quid certainly seems to have mastered. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I would like to congratulate our gone but far from forgotten user quid on being elected as a moderator at Math.SE (congratulations also go to Jack D'Aurizio).

(And it seems to be a useful rule for several reasons.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, it seems to me that some tags which do not have arXiv format are used basically as top-level tags. For example, it seems that &lt;a href=&quot;https://mathoverflow.net/questions/tagged/linear-algebra&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;linear-algebra&amp;#39;&quot; rel=&quot;tag&quot;&gt;linear-algebra&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/tagged/graph-theory&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;graph-theory&amp;#39;&quot; rel=&quot;tag&quot;&gt;graph-theory&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/tagged/set-theory&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;set-theory&amp;#39;&quot; rel=&quot;tag&quot;&gt;set-theory&lt;/a&gt; are used in this way.

(In the sense that they cover quite broad area and that the question which have one of these tags but no arXiv tag can be considered as tagged in accordance with recommendations in the FAQ.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Or, if the questions from the areas mentioned above should also additionally have &quot;arXiv &quot; tag, which tag should be used in these cases.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;EDIT: I have looked a bit through the tag-wikis and saw that the &lt;a href=&quot;https://mathoverflow.net/tags/co.combinatorics/info&quot;&gt;tag-info for co.combinatorics&lt;/a&gt; (&lt;a href=&quot;https://mathoverflow.net/posts/134860/revisions&quot;&gt;revision history&lt;/a&gt;) explicitly mentions graph theory.

In these two cases the two &quot;arxiv&quot; tags are definitely close to graph/set theory and these tags are often used simultaneously. (Out of 2829 questions tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/set-theory&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;set-theory&amp;#39;&quot; rel=&quot;tag&quot;&gt;set-theory&lt;/a&gt;, 1108 are &lt;a href=&quot;https://mathoverflow.net/questions/tagged/set-theory+lo.logic&quot;&gt;also tagged lo.logic&lt;/a&gt;.

Recently it is becoming clear to me that my idea of &quot;research level&quot; is not always the same as that of the moderators. To make my flagging more accurate (yielding a higher &quot;accepted&quot; rate for me and less needless work for me and the moderators) I would like to get a better understanding of when I should (not) flag in practice.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For a concrete example let us consider &lt;a href=&quot;https://mathoverflow.net/q/284458&quot;&gt;Does this geometry theorem have a name?&lt;/a&gt;. I do not know the answer, yet it seems like a basic question about Euclid's geometry, which to me is undergraduate or even high-school level mathematics. Therefore I would guess the OP has a higher chance to get an answer at Mathematics.SE (which I expect to have many more active users) or perhaps &quot;History of Science and Mathematics&quot;.SE or &quot;Mathematics Educators&quot;.SE (whose users might be more familiar with classical geometry &lt;em&gt;à la&lt;/em&gt; Euclid).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, both (quite a few!) voters and the moderator(s) that handled my flag disagree with me. In fact, these two seem to be correlated: I am under the impression that flags for questions with a positive rating by votes tend to take longer to get accepted/declined, and are usually declined.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Should I avoid flagging questions that I think are not research level when they have a positive rating by votes? Should I perhaps downvote such a question instead?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I understand that the latter mean that at least some users think it is a relevant question, so it might be acceptable even if it would not be research level.

In particular, “MathOverflow Inc” has a legal agreement with StackExchange that allows us to separate amicably if the need arises, in particular taking the complete data and name, and allowing us to find our own hosting arrangements. While we certainly hope this won’t ever need to happen, and we’re very happy with all the help and support StackExchange provides us, it’s important that MathOverflow in this sense “belongs to the mathematicians”, held in trust by this legal body.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The board members of “MathOverflow Inc” are Anton Geraschenko, Ben Webster, David Zureick-Brown, François Dorais, Scott Morrison, Todd Trimble, Scott Carnahan, Mariano Suárez-Alvarez and Ravi Vakil. We meet (virtually) every year, and discuss long term issues around MathOverflow. In particular, projects such as obtaining a grant from the &lt;a href=&quot;https://en.wikipedia.org/wiki/Alfred_P._Sloan_Foundation&quot; rel=&quot;nofollow noreferrer&quot;&gt;Alfred P. Sloan Foundation&lt;/a&gt;, generating trackbacks to the arXiv, and implementing the “citation search” feature on MathOverflow, supported by a Zentralblatt backend, have been overseen by the board. We’ve also done a small amount of work ensuring we know approximately what we’d do in the event of needing to leave StackExchange.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are some minor expenses involved in making all this happen. There are the legal costs of starting and maintaining 501(c)(3) status, there have been some hosting costs for generating trackbacks and supporting the citation search feature (although due to Zentralblatt’s support these are now fairly minimal) and of course in order to be able to do those things we need a MathOverflow bank account, etc. During the development of the citation search feature we paid a MathOverflow user for some coding work for a demo.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So far, this has all been funded by a grant from the Alfred P. Sloan Foundation, and kind donations from a small number of generous donors (in fact, from amongst the board members). It’s time, however, to ask for a little more help, and this post serves to announce the existence of a link allowing you to donate to MathOverflow!

It probably has tags &quot;big-list&quot; and &quot;soft-question&quot;, and at least several of the responses received more than 100 upvotes.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So far the search using keywords and other clues from my memory is futile.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There seems to be more big-list and soft-question in the earlier years, and some of them either got closed or deleted.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I wonder if there's a way to search among the deleted posts (just the titles) as a user with minimal rep (like me).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;BTW, is it okay to ask for help in finding a specific post? If that is not frowned upon, I can provide a description of the post I'm looking for.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;In response to @ToddTrimble, the post I'm looking for is about:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;seemingly elementary or simple facts (theorems, concepts, analogies etc) one learned long ago that still amaze you now (or that you later realized are profound). Only one item each entry as per usge.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I actually don't remember THE top upvoted answers, but I recall &quot;the linearity of expectation&quot; got over 100+ while ranking outside of top 5 (by default listing). I was a bit surprised not by this answer itself but that this answer resonated with so many people. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The top answers were relatively less memorable to me because either I didn't have a deep understanding about those, or they were more &quot;predictable&quot;, like some celebrated common knowledge in set theory or number theory (less sure about geometry here).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I will be deeply embarrassed if it turns out that my memory is totally off, but at least as of now the image in my head is vivid.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The phrasing of that entry included &quot;additivity&quot; more likely than not, so it could be &quot;linear additivity of expectation&quot;, &quot;additivity of expectation&quot;, or &quot;expectation is linearly additive&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As for which of the key adjectives (or the corresponding verb) were being used in the title or text, like &quot;trivial&quot;, &quot;profound&quot;, &quot;favorite&quot;, &quot;intriguing&quot;, &quot;amazing&quot;, &quot;dazzled&quot;, etc  ... sorry this I'm really foggy on this part, and I don't remember if there's community wiki or an answer marked as &quot;accepted&quot;.&lt;/p&gt;&#xA;" OwnerUserId="100250" LastEditorUserId="8250" LastEditDate="2017-12-03T05:12:48.140" LastActivityDate="2017-12-05T01:10:32.663" Title="How to know if an old post is deleted, when I cannot find it" Tags="|support|specific-question|deleted-questions|searching|" AnswerCount="2" CommentCount="5" ContentLicense="CC BY-SA 3.0" />

I think it is quite well summarized in the answer here: &lt;a href=&quot;https://meta.mathoverflow.net/q/3254&quot;&gt;Can I somewhere see my own deleted questions?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I will also add that highly upvoted questions with highly upvoted answers are deleted very rarely if at all. (At least here on MathOverflow.) This was already pointed out &lt;a href=&quot;https://meta.mathoverflow.net/questions/3493/how-to-know-if-an-old-post-is-deleted-when-i-cannot-find-it/3495#comment15341_3493&quot;&gt;in Gerry Myerson's comment&lt;/a&gt;. (Of course, moderators can delete any question - they have practically unlimited powers regarding deletion, undeletion, closing, reopening. What I write here is about deletion by regular users.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;All details about deletion can be found here: &lt;a href=&quot;https://meta.stackexchange.com/q/5221&quot;&gt;How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion?&lt;/a&gt; I will briefly summarize stuff which is relevant for highly upvoted questions with highly upvoted answers:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The OP cannot delete their own question which has at least one upvoted answer. So question with highly upvoted answer cannot be deleted in this way.&lt;/li&gt;&#xA;&lt;li&gt;Such question still can be deleted by users who can &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;cast delete votes&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;The question can only be deleted by votes to delete if it is &lt;em&gt;closed&lt;/em&gt; and you need at least &lt;em&gt;three votes&lt;/em&gt;.&lt;/li&gt;&#xA;&lt;li&gt;However, if the question is highly upvoted or has highly upvoted anwer, depending on score &lt;a href=&quot;https://meta.stackexchange.com/questions/50523/should-delete-votes-be-limited-like-close-votes/51071#51071&quot;&gt;more votes might be needed&lt;/a&gt;. For questions like you described (both the question and the top-voted answer with score close to 100) you will need ten delete votes for the post to be deleted.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;However, it seems that your question was mainly about finding one specific post and you remembered that it was highly upvoted. Maybe I am saying stuff you already know, but just in case it can help you (or somebody else) in future searches for similar posts:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Search results can be ordered by score - this helps if you are looking for a highly upvoted posts.&lt;/li&gt;&#xA;&lt;li&gt;You can restrict the search to answers &lt;a href=&quot;https://mathoverflow.net/search?tab=votes&amp;amp;q=is%3aa&quot;&gt;by adding is:a&lt;/a&gt; and to questions &lt;a href=&quot;https://mathoverflow.net/search?tab=votes&amp;amp;q=is%3aq&quot;&gt;by adding is:q&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;Of course, you can refine the search further by &lt;a href=&quot;https://mathoverflow.net/search?tab=votes&amp;amp;q=is%3aa+theorems&quot;&gt;adding keywords&lt;/a&gt; or &lt;a href=&quot;https://mathoverflow.net/search?tab=votes&amp;amp;q=is%3aa+[big-list]&quot;&gt;adding tags&lt;/a&gt;, etc.&lt;/li&gt;&#xA;&lt;li&gt;You can also restrict search to posts with score above certain value, for example: &lt;a href=&quot;https://mathoverflow.net/search?tab=votes&amp;amp;q=is%3aa+score:100&quot;&gt;is:a score:100&lt;/a&gt; means searching for answers with score at least 100.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Sometimes it is more comfortable to search by external search engine. (In particular, if you want to search for some keywords used &lt;em&gt;in comments&lt;/em&gt; rather than in the body of a post, then you should use Google with &lt;a href=&quot;https://www.google.com/search?q=site%3Amathoverflow.net&quot; rel=&quot;nofollow noreferrer&quot;&gt;site:mathoverflow.net&lt;/a&gt; or some other search engine where you can restrict the search to specific domain. Another possibility is to use SEDE. For more details about this see: &lt;a href=&quot;https://meta.mathoverflow.net/q/3247&quot;&gt;Searching for comments&lt;/a&gt;.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;But if you want to somehow use the information that the question/answer was highly voted, then the built-in search is probably the way to go. (Although even while searching with Google, question which has many views and is popular is likely to be ranked higher, you cannot restrict by score or order by score like here when using the site's internal search.)&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2017-12-05T01:10:32.663" LastActivityDate="2017-12-05T01:10:32.663" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

In fact, I'm having some fun formalizing mathematics in the Mizar system, which has just &lt;a href=&quot;http://mizar.org/version/current/html/cgames_1.html&quot; rel=&quot;nofollow noreferrer&quot; title=&quot;Conway&amp;#39;s Games and Some of Their Basic Properties&quot;&gt;one article&lt;/a&gt; on Conway games yet. I want to find out if further formalization would be fruitful, i.e. if the operations defined in the book can be formalized at all. The cited article only defines $-x$ for a game $x$, but gives a pretty good idea how to deal with the highly inductive nature of games and I'm certain I could formalize addition and multiplication. What bothers me is the definition of $y=\frac{1}{x}$, given by $$y=\left\{\left.0,\frac{1+(x^R-x)y^L}{x^R},\frac{1+(x^L-x)y^R}{x^L}\right|\frac{1+(x^L-x)y^L}{x^L},\frac{1+(x^R-x)y^R}{x^R}\right\}$$&#xA;for $x$ positive and only positive $x^L$ considered, which is needed for defining division. Conway, after giving this definition on p.21, writes himself&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Note that expressions involving $y^L$ and $y^R$ appear in the definition of $y$. It is this that requires us to &quot;explain&quot; the definition. The explanation is that we regard these parts of the definition as defining new options for $y$ in terms of old ones.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;In a footnote, the rather trivial example of $\frac{1}{3}=\{0,\frac{1}{4},\frac{5}{16},\ldots|\frac{1}{2},\frac{3}{8},\ldots\}$ is given to show &quot;how the definition works&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I can't see why $y$ is well defined in general. For example, given two uncountable cardinals $\alpha&amp;lt;\beta$ I'm having a hard time seeing how $\frac{1}{\beta-\alpha}$ should be computed. The emphasis here lies on &quot;uncountable&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Claus Tøndering gave a seemingly equivalent definition of the inverse &lt;a href=&quot;http://share.dschola.it/giordanobruno/physic@/100%20PAROLE%20PERla%20scienza/Infinito/Surreal%20Numbers%20-%20Tondering.pdf&quot; rel=&quot;nofollow noreferrer&quot; title=&quot;Surreal Numbers - An introduction&quot;&gt;here on p.44&lt;/a&gt; (if the definition should not be equivalent, please point out why). He defines $y$ through $y^L$ and $y^R$ as such: &#xA;$$0\in y^L$$&#xA;$$z\in y^L \Rightarrow \tfrac{1+(x^R-x)z}{x^R}\in y^L, \tfrac{1+(x^L-x)z}{x^L}\in y^R$$&#xA;$$z\in y^R \Rightarrow \tfrac{1+(x^L-x)z}{x^L}\in y^L, \tfrac{1+(x^R-x)z}{x^R}\in y^R$$&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This is still &quot;too&quot; recursive to be formalized. One of my problems is that I can't comprehend the cardinality of $y^L$ and $y^R$. I mean, I could define $y^L_0 = \{0\}, y^R_0 = \{\}$ and for $n\in\mathbb{N}, n&amp;gt;0$ change Tønderings definitions to $z\in y^L_{n-1} \Rightarrow \ldots\in y^L_n$ and so on (or better: $$y^L_n = \left\{\left.\tfrac{1+(x^R-x)z}{x^R}\right|z\in y^L_{n-1}\right\}\cup\left\{\left.\tfrac{1+(x^L-x)z}{x^L}\in y^L \right|z\in y^R_{n-1}\right\}$$ and $y^R$ analogue) and conjecture $$y^L = \{0\}\cup\bigcup_{n\in\mathbb{N}} y^L_n,\quad y^R = \bigcup_{n\in\mathbb{N}} y^R_n$$&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Here is my problem:&lt;/strong&gt; I really doubt I could prove that. First off, I'm having trouble believing the equality holds, that I could miss something by merely having a countable union. Secondly, $y^L$ and $y^R$ are required to be sets and I can image how they accidentally could become classes this way with some $x$ nefarious enough (maybe $x=\beta-\alpha$ is enough already?), because maybe the set generation process never stops at a certain day. I get couldn't information about this topic at all. In papers about surreal numbers either they are just given like here without further doubt or not explicitly given at all. Some papers, like these from Philip Ehrlich, go deeper into cardinality or other theories above my understanding, so if the issue would be resolved there, I wouldn't have noticed.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;On the matter of the $y^L_n$ and $y^R_n$ being sets, Conway writes&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&lt;strong&gt;Theorem 10.&lt;/strong&gt; &lt;em&gt;We have (i) $xy^L&amp;lt;1&amp;lt;xy^R$ for all $y^L,y^R$.&lt;/em&gt;&lt;br&gt;&#xA;  &lt;em&gt;(ii) $y$ is a number.&lt;/em&gt; [(iii) and (iv) left out]&lt;br&gt;&#xA;  &lt;em&gt;Proof.&lt;/em&gt; We observe that the options of $y$ are defined by formulae of the form $$y''=\frac{1+(x'-x)y'}{x'}$$ where $y''$ is an earlier option of $y$, and $x'$ some non-zero-option of $x$. This formula can be written $$1-xy'' = (1-xy')\frac{x'-x}{x'}$$ which shows that $y''$ satisfies (i) if $y'$ does. Plainly $0$ does. Part (ii) now follows, since we cannot have any inequality $y^L\geq y^R$. [...]&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;As far as my understanding goes, with &quot;$y$ is a number&quot; he means &quot;if $y$ is a game, then it's a number&quot;, as this proof (directly following the remark after the definition) does not indicate the sethood of $y^L$ or $y_R$ in my eyes.&lt;/p&gt;&#xA;" OwnerUserId="118059" LastEditorUserId="8250" LastEditDate="2017-12-14T03:57:37.257" LastActivityDate="2017-12-14T03:57:37.257" Title="My question looks like spam" Tags="|support|spam|quality-filter|" AnswerCount="1" CommentCount="6" ContentLicense="CC BY-SA 3.0" />

However, I see the question (as I understand it) to be too narrow as to be useful to anyone else.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;When simplified and abstracted, my take is that you are asking &quot;Given some not easily testable assumptions (so that obvious reasons for not studying do not apply), are there any reasons you can think of for not studying this particular research problem?&quot;.  If there were many researchers on this planet who were interested in your topic at hand, this question and its answers might serve them, especially given unmentioned specifics like time, place, and politics which might hold for them.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now for my assumption.  I assume the question and its answers will apply only to you, and not to future readers of the forum, because it is too specific and it asks for opinion.  I also assume that (unmentioned) conditions that prompt the question are somewhat temporary and unique to your situation, and that these conditions might render the answers inapplicable to later readers who might find themselves in an even remotely similar position.  I am not seeing the question above as a good fit for MathOverflow because the forum is more for matters that are verifiable and not subject as much to discussion, advice, or opinion (even though there are some advice questions on the forum).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you really need advice, make it a GOOD advice question so that others might make use of the answers.  For example, a reasonable question might be &quot;How can I cope with the situation where an advisor tells me to abandon my current research topic and switch to one that interests me less? By the way, my specific situation is, I am studying X, advisor is telling me to switch because of reason R, and I think that S means there is something worth spending time with.&quot;. This is an example where answers of both kinds can help.  The general answers can talk about why (or why not) you should listen to the advisor and not give pushback, or how to work on two problems at the same time, or the risks you take in following your own (possibly unproductive) track. The subject matter experts can give specific answers about the validity of your assumptions and whether your approach has been tried already.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Some of the above is more appropriate for academia.stackexchange, and some is stuff you should ask a mentor or someone else who knows you and the situation better; we can give war stories and suggestions which may be bad for you because we do not have (and can never get) the whole picture.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I recommend talking to people face to face about this.

Further, the suggestion provided above encourages outsiders to stay outside, and not offer opportunities to make the postings more accessible.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Although this may not be possible with every post, I would encourage people to review with a goal of accessibility, whether they understand the material or not.

Of course when the question appears to be a homework question, there is a clear ethical reason not to give an answer. But in other cases, why is it?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Todd Trimble points out that people worry that answering these questions will lead to more of these questions being asked. I think there is also a broader discomfort with effectively rewarding someone for breaking the rules of the site, even if this doesn't lead to additional questions.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think fedja makes a good point that (1) if politely told where to go along with an answer to the question, the asker is unlikely to return to MO with similar questions and (2) other people are unlikely to go back and read these questions and decide to post on MO.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This seems reasonable to me. There must be some limits to this - I imagine if we all answered questions by exactly the same standards math.stackexchange does, eventually our forum would become very similar to math.stackexchange - but it seems like a small increase in welcomingness right now will not have a negative long-term effect on the quality of questions.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Furthermore, I think the impulse to avoid rewarding bad questions is a bit silly, especially because in most cases the person is breaking the rules out of confused ignorance rather than willful ignorance, or, more fantastically, malice. Maybe the exception here is questions that appear to have been written quickly by a lazy question-asker. Hopefully, though, someone who writes such a lazy question will not consider a terse, lazy answer to be too impolite.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So maybe people like me should feel more comfortable answering low-level and low-quality MO questions, with full answers or in the comments, but combining the answer with a suggestion to take the answer to math.stackexchange or another similar suggestion. &lt;/p&gt;&#xA;" OwnerUserId="18060" LastActivityDate="2017-12-16T18:21:21.963" CommentCount="9" ContentLicense="CC BY-SA 3.0" />

No answer was added, no comment, no reaction at all. Which leads me to the conclusion that the limitation of 7 days may not be suitable for a bounty to achieve its goal. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Especially when a question may require some longer thought or when people don't check this site regularly.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I imagine the limitation of 7 days comes from the Stackoverflow.com site, whose activity level and status of professional importance are completely different from Mathoverflow.com. While the 7 days might be appropriate for the former, it may not be so for the latter.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I hope for some consideration towards increasing this limit. With the current 7 days limit (which I regard as a too low for the system to work as intended in some cases), I will not offer any bounty again and will not recommend it to anyone.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;UPDATE. &#xA;When writing &lt;a href=&quot;https://meta.mathoverflow.net/a/3533/66983&quot;&gt;my response below&lt;/a&gt; to &lt;a href=&quot;https://meta.mathoverflow.net/a/3531/66983&quot;&gt;the answer by Joseph Van Name&lt;/a&gt;, I have looked at the 6 bounty questions and wrote &lt;a href=&quot;https://mathoverflow.net/a/288922/66983&quot;&gt;this answer&lt;/a&gt; that the OP found helpful and awarded the bounty, even though my argument was incomplete to solve the problem posed. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Did the system work as intended in this case?&lt;/em&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;On the surface yes, since it was the bounty through which I have discovered the question. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, it was a huge coincidence that I had found it, as the bounty was about to expire within a day! Had I looked just 1 day later, I would not have discovered and answered this question, with the bounty of 250 points would have possibly lost. In contrast, chanced were much higher if the bounty stayed for somewhat more reasonable period, especially given the coming holidays. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now this leads to the question, how many similarly interesting questions are still there unanswered and undiscovered during their short bounty period, precisely because it was so short?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;And finally, analysing a bit deeper the effect of the bounty on that question, it is clear that even there it did not quite work as might have been intended.

If you put a bounty for a question, then that question will receive more upvotes than if it did not have a bounty in the first place. One should consider the cost of a bounty to be more like 25 pts. A 7 day bounty period for 25 pts is therefore a very good deal since a person who answers will still be rewarded 50 pts for a correct answer within the timeframe.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The purpose of a bounty is not simply to give people extra points for a correct answer if one gives the answer. If the purpose of a bounty were to simply reward a good answer, then a longer bounty period would be more understandable. However, the purpose of a bounty is in part to give the question more attention and to signal its importance.  When I have given bounties in the past, I have considered the 50 pt investment into the bounty to be a very good investment even if the question has not been answered simply because the bounty gives the question more attention.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If you would like to offer an entity points when it gives a correct answer, then you may freely give your points for that answer as a bounty after the question has been answered.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;A longer bounty period will simply mean that every individual bounty question will be given less attention for the time that it is a featured question since there will be many questions with bounties to choose from. This sort of bounty inflation will defeat the purpose of having a longer bounty period.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;A longer bounty period will not guarantee that anyone will answer the question. If a question has been unanswered for 7 days, then it is unlikely that such a question will be answered within a month. Some questions are not answered because they are difficult.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;In the case that a question goes unanswered after the 7 day bounty period, one may put up another bounty to that question. The 7 day limit is only for those who do not have enough points to pay for multiple bounties. If multiple people consider a question to be important, then those multiple people can each offer a bounty on that question. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;Since the Hereditary Principle question has 38 upvotes and over 1000 views, it seems like people are in fact interested in such a question.

Then, not a single up-vote was added as the result of the bounty. This disproves the suggested effect that the up-votes attracted would compensate for the bounty. What this also likely means, the bounty did not attract any further attention. In my interpretation, the reason is that active users have already seen the questions, whereas a bounty of 7 days does little to attract attention of less regular users, who could provide additional valuable insight.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I would assume the ultimate purpose of the bounty should be to encourage quality answers. If &quot;attracting attention&quot; only refers to further up-votes and views without any tangible activity, I would question its usefulness, and &lt;strong&gt;would not feel compelled to ever offer a bounty again&lt;/strong&gt;. In my view, the prime goal should be valuable activity, whereas attracting attention is merely a byproduct effect. It is the former that we (I) want to reward, not the latter. Especially if it will take time for the person to write a good answer, I would like to reward it.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I did not know that it was possible to assign reward after the answer. However, this way I would still lose valuable inputs by busy people, who might have been more compelled to take the time if the reward was declared beforehand. That way my bounty still fails to achieve the positive effect I am aiming at.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;At the time of writing, I can see &lt;a href=&quot;https://mathoverflow.net/?tab=featured&quot;&gt;6(!) featured questions in total on the Mathoverflow site&lt;/a&gt;! For the whole mathematics! With none of them even close to my area, just to put it in a context. I would hardly call it &quot;too many questions with bounties to choose from&quot;. In comparison, &lt;a href=&quot;https://stackoverflow.com/?tab=featured&quot;&gt;the Stackoverflow site has 366 bounty questions&lt;/a&gt;! That I can &lt;a href=&quot;https://stackoverflow.com/questions/tagged/database&quot;&gt;refine by selecting the database tag&lt;/a&gt;, to get only 2, which explains how the 7 days over there makes perfect sense. Whereas the 6 questions in total on Mathoverflow, also explains how the 7 days there is way too short. In fact, working with the ratios, we arrive at&#xA;$$ 7 \ {\rm days} \times 366/6 = 427 \ {\rm days},$$&#xA;to reach the proportion of the SO.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;A longer bounty period will very likely increase the chance of an answer, because the question will get more likely noticed by more busy people who only come here sporadically. In contrast, the 7 days period will be of little effect for anyone in this category.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Being myself not a regular user, I probably fall in the category of the people who &quot;do not have enough points for multiple bounties&quot;. However, more fundamentally, when I see how little effect the bounty achieves with the current system, I don't feel encouraged to keep offering bounties, even if I had more than enough points. Concerning bounties by other people, none had been offered that far for this question, despite the obvious interest judged by the number of votes.

I did not get an answer I wanted. If there was some answer at all, maybe I awarded the bounty to the closest match, but I still would like to see an answer fulfilling my original requirements. What can I do next?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;One possibility is adding new bounties on the same question repeatedly. This is probably not very efficient and I could exhaust non-negligible part of my reputation after a few iterations. (This would be difficult especially for low rep users.)&lt;/li&gt;&#xA;&lt;li&gt;I could mention (in a comment or - if it is my question - directly in a question), that if somebody posts an answer fulfilling some criteria, I will reward such answer with a bounty. A clear disadvantage of this is that this will not be very prominently visible.&lt;/li&gt;&#xA;&lt;li&gt;There is also this feature request: &lt;a href=&quot;https://meta.stackexchange.com/q/267021&quot;&gt;Request new function Standing Bounty&lt;/a&gt;. But considering that it is two years old and currently at score &lt;span class=&quot;math-container&quot;&gt;$-12$&lt;/span&gt;, it is not very likely that it gets implemented.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Would creating a list of such bounties be potentially useful. I would imagine each entry to contain description of the question and what the user offering the potential bounty looks for. And the entry would be considered as a commitment to award a bounty if the answer they are satisfied with is posted.&lt;/p&gt;&#xA;&lt;p&gt;And if something like that could be useful, what would be the best way to implement it? Would it be a dedicated meta post? (I am afraid it might get too long.) Would perhaps a dedicated chat room be more suitable? Or would a better solution be some wiki-like page not directly on MathOverflow website?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;To prevent misuse of the list, maybe some rules would be needed? Probably only person who already gave at least one bounty on that question should post there?

However, not all past bounties are equal. The fact that a user offered bounty for some question in the past does not automatically mean that they are still interested in (new answers for) that question. Somebody might, for example, just add a bounty simply to reward an answer which is already posted. However, the proposal here is mainly for the question where the user offering a bounty is &lt;em&gt;still interested&lt;/em&gt; in the question and is &lt;em&gt;willing to reward&lt;/em&gt; a new answer by additional bounty, if a satisfactory answer is posted.&lt;/p&gt;&#xA;&lt;p&gt;Several posts here on meta suggests that some users are not quite satisfied with visibility of the featured questions. For example: &lt;a href=&quot;https://meta.mathoverflow.net/q/2936&quot;&gt;Is bounties period sufficient?&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/q/3530&quot;&gt;Why is it not possible to offer a bounty for longer than 7 days?&lt;/a&gt; (In other words, some users feel they did not got their &lt;s&gt;money&lt;/s&gt; reputation points' worth after they offering a bounty.) In fact, I have mentioned rather similar proposal in &lt;a href=&quot;https://meta.mathoverflow.net/q/2936#3043&quot;&gt;my answer to Is bounties period sufficient?&lt;/a&gt; I am posting this here so that it is slightly more visible and also so that various possible implementations of this can be discussed here. (And also whether something like this could be potentially useful.)&lt;/p&gt;&#xA;&lt;p&gt;I will also add that I have proposed something similar on Mathematics Meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/23647&quot;&gt;Could list of unresolved past bounties be useful?&lt;/a&gt; The question was quite well received - the score of the question is currently +37 and answer with a proposed solution is at +8 - but the proposal was not successful.

Users could post the questions there, together with short commentary what they are looking for, why they are not satisfied with the answers posted so far and what makes the question interested. Basically I would imagine something along the lines of the chatroom suggested on Mathematics site some time ago. You can see the &lt;a href=&quot;https://math.meta.stackexchange.com/questions/23647/could-list-of-unresolved-past-bounties-be-useful/23715#23715&quot;&gt;proposed rules for this room&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What are possible advantages of posting this in chat room?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;If users have some comments on the question, they can respond there. Maybe that could lead to some improvements of the questions or even partial solutions.&lt;/li&gt;&#xA;&lt;li&gt;You can easily find &lt;a href=&quot;https://chat.stackexchange.com/search?q=tag&amp;amp;room=43020&quot;&gt;all (oneboxed) questions posted there&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;You can find questions in a specific tag &lt;a href=&quot;https://chat.stackexchange.com/search?q=general-topology&amp;amp;user=&amp;amp;room=43020&quot;&gt;like this&lt;/a&gt; or &lt;a href=&quot;https://chat.stackexchange.com/search?q=questions%2Ftagged%2Fgeneral-topology&amp;amp;user=&amp;amp;room=43020&quot;&gt;like this&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Of course, the search functionality work in any chatroom. You can search for &lt;a href=&quot;https://chat.stackexchange.com/search?q=tag&amp;amp;user=&amp;amp;room=70737&quot;&gt;all oneboxed questions&lt;/a&gt; and also for &lt;a href=&quot;https://chat.stackexchange.com/search?q=ct.category-theory&amp;amp;user=&amp;amp;room=70737&quot;&gt;questions in a specific tag&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Does it have a chance of getting some attention?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Despite the fact that users on Mathematics site apparently liked the proposal (at least the question on meta gained enough upvotes), the chat room did not really pick up there. I hoped that if I make at least some users aware of the room, the word would spread further. I have summarized my effort &lt;a href=&quot;https://chat.stackexchange.com/transcript/19138/2017/7/8&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Probably here on MO, the chatroom would have a better chance of appearing in the sidebar. You might have noticed that sometimes two chatrooms are &lt;a href=&quot;https://meta.stackexchange.com/questions/257677/how-are-the-chatrooms-shown-in-the-sidebar-selected&quot;&gt;shown in the sidebar&lt;/a&gt; when you are displaying the site. AFAICT the rooms are selected based on whether they had some recent activity.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The proposed room would have rather low traffic - new messages would be posted there only if somebody has some bounty question they are interested in. So on a site like Mathematics which has &lt;a href=&quot;https://chat.stackexchange.com/?tab=site&amp;amp;sort=active&amp;amp;host=math.stackexchange.com&quot;&gt;many active chatrooms&lt;/a&gt;, this room would almost never be displayed in the sidebar. For &lt;a href=&quot;https://chat.stackexchange.com/?tab=site&amp;amp;sort=active&amp;amp;host=mathoverflow.net&quot;&gt;rooms associated with MathOverflow&lt;/a&gt; the situation is somewhat different. The only room with non-negligible activity is &lt;a href=&quot;https://chat.stackexchange.com/rooms/info/9417/homotopy-theory&quot;&gt;Homotopy Theory&lt;/a&gt;. So even a low-traffic room like this would have a chance to appear in the sidebar when some new messages are posted.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In some discussions several users mentioned that they do not even visit the featured tab. The chatrooms displayed in the sidebar are somewhat bigger than the blue number on the featured tab, so if displayed there, the visibility of this chatroom could possibly be comparable with the featured tab. &lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2017-12-24T14:51:12.573" LastActivityDate="2017-12-24T14:51:12.573" CommentCount="0" ContentLicense="CC BY-SA 3.0" />

I will quote from this discussion:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://chat.stackexchange.com/transcript/10243?m=39656903#39656903&quot;&gt;François G.

  <row Id="3587" PostTypeId="2" ParentId="3580" CreationDate="2018-01-15T14:59:12.303" Score="9" Body="&lt;p&gt;There's a fair bit to sort out here. I actually think the question adumbrated in the question title is not precisely the one you want answered. As I see it, we don't have to wring our hands over whether we're being sufficiently open or fair to questions that have a numerological character. Try entering '&lt;a href=&quot;https://mathoverflow.net/search?tab=relevance&amp;amp;q=numerology&quot;&gt;numerology&lt;/a&gt;' into the MO search bar, and you'll see quite a few good questions pop up. As I see it, it's not that there is some innate prejudice in the Community against 'numerology' as mathematicians use the word (there probably is prejudice toward its more mystical contexts). Of course not. We all have struggles not tied to deductive reasoning per se, where we look for patterns, apply guesswork, etc. etc., and occasionally ask each other for help. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Speaking for myself, questions are approached on a case-by-case basis. Here are some of the criteria I apply. Is the question clear and precise? Does it seem likely that someone can answer it? Does the level seem appropriate for a professionalized community? Etc. And I think I'm not alone in taking that case-by-case approach. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have seen some good faith effort from you to try to understand the norms of the community and make adjustments to your questions. There seems to be some disagreement with my casting a fifth vote to reopen the thread &#xA;&lt;a href=&quot;https://mathoverflow.net/questions/288114/e-6-e-8-and-coxeters-anti-prismatic-projections-of-the-n-dimensional-cr&quot;&gt;$E_6$, $E_8$, and Coxeter&amp;#39;s (anti-)prismatic projections of the n-dimensional cross-polytopes&lt;/a&gt; where I had cast a fifth and final vote to reopen, based partly on my perception of good faith effort. And I must admit, I'm having some second thoughts. As mathematics goes, the question still seems pretty vague to me, which is to say I don't have a clear idea what's in your mind when you ask such questions, or how someone would know what you're after. That may be partly due to my shortcomings, but here again I don't think I'm alone in this, and I suspect you generally needs to work yet harder to bring some of these questions into a good useful shape for MO. The closures may be due to people who share these concerns. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;[I do often worry about knee-jerk reactions from the community. Hey, I worry about them in myself. So I struggle daily to maintain an open mind, and to seek pragmatic constructive solutions to problems as they arise. But, I'm struggling alongside other people here. May I say that I bristle a little at being painted as some sort of hero of free thought at MO -- maybe not as much as I bristle when I am portrayed as an &lt;em&gt;enemy&lt;/em&gt; of free expression (as has sometimes happened), but still. It's just a little too inviting of invidious comparisons with others who I think are also acting in good faith. Cf. some of the discussions over at Math.SE meta, where I think my actions and attitudes have been overstated by you.] &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In addition to the suggestion that you endeavor to make your mathematical questions much clearer, I have some others that I hope you will take to heart, and which I think might help moving forward: &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;Resist the urge to leave so many comments. Very often when someone leaves a comment, you leave four or five in return. In ordinary conversation this would likely be experienced as being talked at. Actually, leaving excessive comments is considered a site violation. The lack of follow-up from your presumed interlocutor should be a sign not to go on and on. Part of the StackExchange model and software is that it is expressly &lt;em&gt;not&lt;/em&gt; designed for extended discussion. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Resist the urge to philosophize. There has been way too much about Peircean abduction, or alleging an auto-immunity disorder within the community, to mention two specific things. As Lucia said succinctly: just stick to the math. I do think he (yes, he) is right that you've had a tendency to diagnose what is wrong in our community and what should be changed, and inevitably this provokes resentment, as you are still new here. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Adding to the last bullet point: please avoid any urge to get defensive about how your MO questions are treated within the MO questions themselves. This includes invoking names like that of Coxeter to defend your question as being research level.

Wow, it was much more than I asked. Basically, it opened up my eyes to something in front of me all the times, but I had failed to see it all the times. That answer was a new beginning for something that had started 6 years and a half year ago and continued for another 4 years and a half year!&lt;br&gt;&#xA;The paper has been dedicated to David Fowler for the reasons mentioned in the paper and &lt;a href=&quot;https://meta.mathoverflow.net/q/3598/29316&quot;&gt;here&lt;/a&gt; (link to meta-MO post). But, I believe both Fowler and I should thank Francois for his short enlightening answer. Here is the abstract of the paper, hoping it deserves the name of David Fowler, Christopher Zeeman, Jeremy Gray, and Francois Ziegler who directly or indirectly, knowingly or unknowingly, encouraged me to finish my journey. &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;This paper proposes a reading of the history of equivalence in&#xA;  mathematics. The paper has two main parts. The first part focuses on a&#xA;  relatively short historical period when the notion of equivalence is&#xA;  about to be decontextualized, but yet, has no commonly agreed-upon&#xA;  name. The method for this part is rather straightforward: following&#xA;  the clues left by the others for the ‘first’ modern use of&#xA;  equivalence. The second part focuses on a relatively long historical&#xA;  period when equivalence is experienced in context. The method for this&#xA;  part is to strip the ideas from their set-theoretic formulations and&#xA;  methodically examine the variations in the ways equivalence appears in&#xA;  some prominent historical texts. The paper reveals several critical&#xA;  differences in the conceptions of equivalence at different points in&#xA;  history that are at variance with the standard account of the&#xA;  mathematical notion of equivalence encompassing the concepts of&#xA;  equivalence relation and equivalence class.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;" OwnerUserId="29316" LastEditorUserId="14094" LastEditDate="2019-05-15T07:58:44.523" LastActivityDate="2019-05-15T07:58:44.523" CommentCount="0" CommunityOwnedDate="2018-01-22T15:53:14.357" ContentLicense="CC BY-SA 4.0" />

So what I &lt;a href=&quot;https://meta.mathoverflow.net/revisions/3613/2&quot;&gt;originally posted&lt;/a&gt; was actually an answer to a different question. Therefore I have expanded the answer a bit to describe various ways &lt;strong&gt;how to access chat&lt;/strong&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course, one can simply access chat by using the url &lt;a href=&quot;https://chat.stackexchange.com&quot;&gt;https://chat.stackexchange.com&lt;/a&gt; - and if somebody uses chat frequently, the browser probably remembers the url and after you start typing the link in the address bar, the rest of the rest will be completed by the browse. After getting to chat you can choose to view rooms &lt;a href=&quot;https://chat.stackexchange.com/?tab=site&amp;amp;host=mathoverflow.net&quot;&gt;associated with a specific site&lt;/a&gt;, your &lt;a href=&quot;https://chat.stackexchange.com/?tab=favorite&quot;&gt;favorite rooms&lt;/a&gt;, etc.&lt;sup&gt;1&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, the intended question is about navigation to chat through the user interface of the site.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Through menu in the top bar&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You can get to chat through the top bar. (Using the same button which can also be used to &lt;a href=&quot;https://meta.mathoverflow.net/questions/1234/how-to-get-to-meta&quot;&gt;get to meta&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you look at the top-bar you can see several buttons &lt;em&gt;on the right&lt;/em&gt; and to get to chat, you can use the rightmost of the meta - as shown in this screenshot:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/Ql1yt.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/Ql1yt.png&quot; alt=&quot;Screenshot&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I will just add that this navigation to chat/meta used to be on the left.

(Between the community bulletin and linked/related questions.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/NQRp7.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/NQRp7.png&quot; alt=&quot;screenshot of chatroom&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are some things worth pointing out:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;At most two chatrooms are shown in the sidebar. So on a site with many chatrooms, there is not a big probability that you can see there exactly the room which you want. (Which is why I personally view the rooms shown in the sidebar more as a tool how active chatrooms are advertised rather than a way to navigate to chat.) However, at the moment, &lt;a href=&quot;https://chat.stackexchange.com/transcript/9417&quot;&gt;Homotopy Theory&lt;/a&gt; is the only MathOverflow chatroom  with not negligible activity, so if the rooms are shown in the sidebar, you're pretty much guaranteed that this will be some of them. (A few other rooms have been &lt;a href=&quot;https://meta.mathoverflow.net/questions/355/specialized-chat-rooms&quot;&gt;suggested in the past&lt;/a&gt;.)&lt;/li&gt;&#xA;&lt;li&gt;I am not sure how are the room displayed in the sidebar selected. But it seems that usually the rooms which recently had some activity are chosen. See also: &lt;a href=&quot;https://meta.stackexchange.com/q/257677&quot;&gt;How are the chatrooms shown in the sidebar selected?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;I am also not sure which factors decide whether the rooms are shown in the sidebar at all. An advice I got some time ago from an experienced user (I can't find a link now) was that they are more likely to be displayed if there is enough vertical space on the right. You can try yourself whether you will get them more often when displaying a question with many answers - be it &lt;a href=&quot;https://mathoverflow.net/search?q=answers%3A5&quot;&gt;on the main site&lt;/a&gt; or &lt;a href=&quot;https://meta.mathoverflow.net/search?q=answers%3A5&quot;&gt;on meta&lt;/a&gt; - than just a random question&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Still, I will stress that what I write in the last two bullet points is based just on my experience - I did not find any official documentation. If you are interested in more details about this, then probably the right place where to search (or ask) would be &lt;a href=&quot;https://meta.stackexchange.com/questions/tagged/chat+sidebar&quot;&gt;Meta Stack Exchange&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Using link in the footer&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Yet another way to navigate to chat is to use the link which is in the footer of any page: &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/W0Z0u.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/W0Z0u.png&quot; alt=&quot;screenshot of the footer&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;I will add that the url &lt;a href=&quot;https://chat.stackexchange.com&quot;&gt;https://chat.stackexchange.com&lt;/a&gt; is link to Stack Exchange chat - which also includes rooms with MathOverflow as the parent site, since MO is a part of the SE network.

So I understand the question as: &amp;quot;Is it possible to find user account in situations similar this?&amp;quot; (Also, I will try to answer this from a viewpoint of &lt;em&gt;regular users&lt;/em&gt;. Moderators might have some more tools at their disposal. However, if you think that you were subjected to &lt;a href=&quot;https://meta.mathoverflow.net/tags/serial-voting/info&quot;&gt;serial downvoting&lt;/a&gt; and want mods to investigate, flagging might be a reasonable way to ask them to alert them to the situation. But in the situation described above this is a moot point, since the votes have already been reversed. And this is only marginally related to your question - since in such situations mods will possibly revert the votes if you were serially downvoted, but they will not tell you identity of the user - which seems to be what you're asking about.)&lt;/p&gt;&#xA;&lt;p&gt;I'll also add that trying to find out who cast downvotes on my post is, in my opinion, not a constructive use of my time. But maybe some of the stuff mentioned below can be useful in some situations even when looking for useful information.&lt;/p&gt;&#xA;&lt;p&gt;The third thing I should mention is that one of the key features of Stack Exchange software is that &lt;a href=&quot;https://meta.stackexchange.com/questions/12984/is-there-a-way-to-see-who-voted-on-your-posts&quot;&gt;voting is anonymous&lt;/a&gt;. (And this is unlikely to change.) Although in some situations you might &lt;em&gt;guess&lt;/em&gt; who downvoted/upvoted your post, you cannot know for sure. (To mention specific example to show what I mean, when I look at &lt;a href=&quot;https://meta.mathoverflow.net/users/61536/taras-banakh?tab=topactivity&quot;&gt;the OP's profile&lt;/a&gt; here on meta, I see how many upvotes/downvotes he cast on meta until now. And if later today this answer is at &lt;span class=&quot;math-container&quot;&gt;$-1$&lt;/span&gt; and I see that counter showing number of downvotes on his profile page has increased, then it's quite natural to suspect that the downvoter &lt;em&gt;might have been him&lt;/em&gt;, but it is very far from a proof.)&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;After the disclaimer above, let us have a look at your question, which can be interpreted in several ways.&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;em&gt;If my &lt;a href=&quot;https://mathoverflow.net/users/current?tab=reputation&quot;&gt;reputation tab&lt;/a&gt; shows a change of reputation saying &lt;a href=&quot;https://meta.mathoverflow.net/questions/337/loss-of-reputation-because-a-user-was-removed&quot;&gt;user was removed&lt;/a&gt;, is it possible to find out which user was it?&lt;/em&gt; No, if user's account is deleted and in situations where this leads to removal of votes, you cannot find out which specific account was removed. This is discussed in more detail here: &lt;a href=&quot;https://meta.stackexchange.com/q/295002&quot;&gt;Is there a way to know which user was removed?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;em&gt;Is it possible to find a list of all users that were deleted recently/during this week/during some specific time period?&lt;/em&gt; As far as I know, the site does not offer you possibility to do this. But you could use the data from &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;data explorer&lt;/a&gt; and the fact that they are only &lt;a href=&quot;https://meta.stackexchange.com/questions/145697/when-will-data-se-get-updated-data/145732#145732&quot;&gt;updated once a week&lt;/a&gt;. (Currently it is Sunday morning around 3:00 UTC - it used to be on Mondays.) This means that some stuff which was deleted can still be in the database until the next update. (I think it might be reasonable to add additional restrictions so that you do not have too many results - there is a limit on number of results of SEDE query; &lt;a href=&quot;https://meta.stackexchange.com/questions/213050/why-cant-i-pull-in-all-the-so-users-from-data-explorer&quot;&gt;SEDE returns only first 50000 results if the query returns more results than that&lt;/a&gt;. In this case, you say that users' reputation was above 1000, so you could use &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/810458/find-all-users-above-given-reputation?rep=1000&quot; rel=&quot;nofollow noreferrer&quot;&gt;this query&lt;/a&gt;. Or you can try to restrict your attention on users &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/query/810460/users-above-given-number-of-upvotes?votes=100&quot; rel=&quot;nofollow noreferrer&quot;&gt;above certain number of votes&lt;/a&gt;.) You can download the results - and then simply sit and wait, download results of the same queries during the next week - after the update of the data in SEDE - and compare them. You will get list of the users that were deleted.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;em&gt;Which are the posts on which I lost/gained reputation?&lt;/em&gt; You did not ask specifically about this, but if somebody sees that some of the upvotes/downvotes on were removed, they might also be curious which are the posts in question. (The reputation tab simply says &amp;quot;User was removed&amp;quot; without showing that exact posts where the vote tally changes.) Here I cannot offer any better suggestion than to occasionally download the breakdown of your reputation by post which is available here: &lt;a href=&quot;https://mathoverflow.net/reputation&quot;&gt;https://mathoverflow.net/reputation&lt;/a&gt; By comparing two versions from various dates you might be able to find out the post which gained some downvotes/upvotes in that period. &lt;strong&gt;EDIT:&lt;/strong&gt; Much better way to find the influenced posts was explained by Glorfindel, see his answers here: &lt;a href=&quot;https://meta.stackexchange.com/q/126698#312191&quot;&gt;How can I find posts related to lost reputation due to a “user was removed” message?&lt;/a&gt; and &lt;a href=&quot;https://math.meta.stackexchange.com/q/3857#32071&quot;&gt;Is it possible to know which posts were affected by user removal?&lt;/a&gt; (This approach uses Stack Exchange API. As pointed out in the comments, you'll need Stack Overflow account if you want to use this.)&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;em&gt;I had exchange in comments with some user, now the comments are deleted. Can I find username/user account?&lt;/em&gt; We will have a closer look at this problem below.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;strong&gt;How to find a user I interacted with - if the comments were deleted?&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;This is actually the part question which I can consider useful. It is possible that you had interaction with some user and you want to find that user - you have something to add. But the comments were, for some reason, deleted.&lt;/p&gt;&#xA;&lt;p&gt;It definitely helps if you remember under which post you had the comment exchange.&lt;/p&gt;&#xA;&lt;p&gt;Some things that can be tried are:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;Check your &lt;a href=&quot;http://stackexchange.com/users/current?tab=inbox&quot;&gt;global inbox&lt;/a&gt;. Sometimes, but not always, deleted comments stay there.&lt;/li&gt;&#xA;&lt;li&gt;Long exchanges in comments can be moved to chat (automatically or by moderators). If the comment exchange you're looking for was rather long, it might be worth looking in chat. You can have look at &lt;a href=&quot;https://chat.stackexchange.com/?tab=site&amp;amp;sort=active&amp;amp;host=mathoverflow.net&quot;&gt;rooms imported from main site&lt;/a&gt;. (Those are the rooms with the title &amp;quot;Discussion between userA and userB&amp;quot; and description started &amp;quot;Imported from a comment discussion on ...&amp;quot;) Or you can look at your chat profile and check the recent messages posted by you. (If a conversation you were part of was moved to chat, the comments you posted in that conversation will also appear as chat messages in that room.)&lt;/li&gt;&#xA;&lt;li&gt;If you remember &lt;em&gt;on which question&lt;/em&gt; you had the discussion, you can check whether the comments can be found using Wayback Machine or whether they are still in Google Cache.&lt;/li&gt;&#xA;&lt;li&gt;And you can also try to use data explorer - assuming that the deleted comments were already there &lt;em&gt;before&lt;/em&gt; the last data dump, but the data in data explorer have not been updated since the deletion. (You can look for comments on specific post or for all comments under your post, etc.)&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;Of course, in neither of the above solutions you can be sure that you actually find the deleted comments. But if you are really looking for something, they might be worth trying. I will add link to this discussion on another meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/13328&quot;&gt;Are there some possibilities for users below 10k to see deleted posts of other users?&lt;/a&gt; In an answer to this question you can find a SEDE query which shows comments on a specific posts: &lt;a href=&quot;https://math.meta.stackexchange.com/q/26072#26074&quot;&gt;Why were the constructive comments deleted along with one poor comment?&lt;/a&gt; If you would like to make a query looking for all comments on your posts, you can try to modify some of the queries here: &lt;a href=&quot;https://meta.mathoverflow.net/q/3266&quot;&gt;Is it possible to search for posts/questions of an user &lt;span class=&quot;math-container&quot;&gt;$X$&lt;/span&gt; commented on/answered by the user &lt;span class=&quot;math-container&quot;&gt;$Y$&lt;/span&gt;?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;I should add that I can see that some users might see investigating stuff like this problematic. If a user decided to remove their account, it's basically their personal business. (And if it was done by moderators, then the reasons should be kept private, too.)&lt;/p&gt;&#xA;&lt;p&gt;On the other hand, I also understand the natural curiosity - many users saw a recent reputation change citing &amp;quot;user was removed&amp;quot; on their profile page, so they might be curious what actually happened. (Although it seems that quite often - unlike in the case of the OP - the reputation change is negative, which suggests that in those cases upvotes were removed after the deletion of a user's account.)&lt;/p&gt;&#xA;&lt;p&gt;In my answer I described some tools how to get an information about &lt;em&gt;some&lt;/em&gt; deleted stuff - but all of this information comes from &lt;em&gt;publicly available&lt;/em&gt; sources. So I hope that the answer I posted is acceptable even for users who have dim view on looking at accounts' deletions by regular users.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2020-07-10T06:41:39.493" LastActivityDate="2020-07-10T06:41:39.493" CommentCount="2" ContentLicense="CC BY-SA 4.0" />

Relevant thread on Meta Stack Exchange: &lt;a href=&quot;https://meta.stackexchange.com/q/431&quot;&gt;Any way to send a personal message to another user?&lt;/a&gt; This was briefly discussed also on this meta: &lt;a href=&quot;https://meta.mathoverflow.net/q/663&quot;&gt;Should we request a Private Message system?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So anything you post will be visible not only to the user you're addressing but also to other users.&lt;sup&gt;1&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Comment.&lt;/strong&gt; One of generally accepted ways is that you post a comment somewhere where the user in question is notified. It is probably a good idea to suggest that the conversation can continue elsewhere (e.g., meta or chat) if the comment is not actually related to the post where you're commenting. And also coming back later and clean-up the comments which are unrelated to the post (after they've already served their purpose and you got the intended information to the user in question) seems to be a polite thing to do.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The system of notifications is quite complex and if you are interested in knowing all details when comment reply of the form @username notifies a user, you can have a look at the links &lt;a href=&quot;https://meta.mathoverflow.net/tags/comment-notification/info&quot;&gt;collected in the comment-notification tag-info&lt;/a&gt;. But whenever the username is offered in autocompletion (i.e., when you write @ in a comment and then press tab) you can be sure that the user is notified about your comment.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Chat.&lt;/strong&gt; Another very reasonable option is to contact user &lt;a href=&quot;https://chat.stackexchange.com/?tab=site&amp;amp;sort=active&amp;amp;host=mathoverflow.net&quot;&gt;in chat&lt;/a&gt;. If you search for the username &lt;a href=&quot;https://chat.stackexchange.com/users&quot;&gt;among chat users&lt;/a&gt;, you can find chat profile of this user. (Not every user has a chat profile. But people who are on this site long enough are very likely to have one - even if they never intentionally joined chat, it's very probably that they participated in a comment thread that was moved to chat - either by a moderator or by an automated process after the comment thread became too long.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you find the chat profile of this user, you can see there whether they were active in some of existing chatrooms. Depending on what you want to discuss you can can either invite the user to already existing chatroom or create a new chatroom and invite the user into this room. (And if the user was recently active in some of the chat rooms, it possible to ping them there using @username syntax. The users who are &quot;pingable&quot; in this way are precisely those &lt;a href=&quot;https://meta.stackexchange.com/questions/226321/does-ping-work-in-chat-with-no-autocompletion&quot;&gt;whose name is offered in autocomplete&lt;/a&gt;. Either way - invitation or chat ping in a room where the user was recently active - the user gets a notification about this.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;See also: &lt;a href=&quot;https://math.meta.stackexchange.com/q/22037&quot;&gt;How do I invite a user to chat?&lt;/a&gt; (Mathematics Meta) and &lt;a href=&quot;https://meta.stackexchange.com/q/57537&quot;&gt;How do I contact other users?&lt;/a&gt; (Meta Stack Exchange)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Email.&lt;/strong&gt; Many users have published their email address (or their website - which usually contains the email address) in their user profile. Or possibly you can find their email from their name - since many users use their real name as the username. So this is also an option.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Still it is probably worth thinking for a while whether you really want to contact user in this way. And you might also have a look at their profile - since some users made their preference for contacting them there. For example, if their included their email address there, that might be a slight indication that they do not mind being contacted via email that much. But some users have mentioned quite clearly in their profile whether they wish to be contacted off-site or not. Here are two examples that are taken from actual MathOverflow profiles, but slightly modified: &quot;You can contact me at potter [at] math [dot] hogwarts [dot] edu&quot; or &quot;Please do not send me private e-mail to call my attention to comments, questions, or other matters related to MathOverflow.&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I will also add that my personal opinion is that if this is issue related closely to MathOverflow and if it might be useful that other users see the discussion too, then it is probably better to discuss this on site than via email. (For example, if you start a discussion in chat with a specific user related to some MO question, it's quite likely that some other users might notice the discussion in chat and they might join your discussion.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Contacting users via email was discussed on this meta before, here is a link: &lt;a href=&quot;https://meta.mathoverflow.net/q/2038&quot;&gt;Community standard for contacting users off of MO?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;The exception is that &lt;em&gt;moderators&lt;/em&gt; have possibility to contact users privately, so that only the user in question and diamond-wearing users see the content of the exchange. This can be done either using moderator messages or in private chatroom.

(You can see that all answers by this user are related to the site design and it is clear from them that this user at least helped with some stuff - I would even guess that they had the main responsibility for taking care of how the site looks, but I did not see this explicitly stated in those posts.) However after looking at &lt;a href=&quot;https://stackexchange.com/users/21721/jin&quot;&gt;their network profile&lt;/a&gt;, it seem that they weren't really active for some time.

So the logo predates this transition. So people who started the site are in the best position to help you. And the &lt;a href=&quot;https://meta.mathoverflow.net/users?tab=moderators&quot;&gt;moderators of MathOverflow&lt;/a&gt; are probably in good position to get to them.

(Since the moderators get notifications about new meta posts in their inbox, it's rather unlikely that none of them is aware of this post.) Still, as &lt;a href=&quot;https://meta.mathoverflow.net/questions/833/who-are-the-mathoverflow-moderators&quot;&gt;explained in another post&lt;/a&gt;, you can contact MO moderators at &lt;code&gt;moderators@mathoverflow.net&lt;/code&gt;.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;Scott Morrison was one of the authors of &lt;a href=&quot;http://www.ams.org/notices/201006/rtx100600701p.pdf&quot; rel=&quot;nofollow noreferrer&quot;&gt;the article about creation of MO in Notices&lt;/a&gt; and also of the &lt;a href=&quot;https://sbseminar.wordpress.com/2009/10/14/math-overflow/&quot; rel=&quot;nofollow noreferrer&quot;&gt;announcement of this site at Secret Blogging Seminar&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;This might be closer to a longer comment than a real answer - I will gladly convert this to comment (or series of comments) - if the prevalent opinion is that this is the preferable course of action.

The fact that the edit was rejected or that the edits were approved but not unanimously suggests that some users did not like those edits.

I will list here two recent examples, here is &lt;a href=&quot;https://mathoverflow.net/review/suggested-edits/95498&quot;&gt;suggested edit review with custom message&lt;/a&gt; and here is another one &lt;a href=&quot;https://mathoverflow.net/review/suggested-edits/95609&quot;&gt;where one of predefined reasons was chosen&lt;/a&gt;. (I have included them merely as examples to make clear where the results of suggested review can be find and what you can read there. I do not link them to attract attention to specific users. Still, I chose examples that are related to TeXifying titles, since this was what prompted this discussion.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;After you gain &lt;a href=&quot;https://math.stackexchange.com/help/privileges/edit&quot;&gt;full edit privileges&lt;/a&gt;, your edits are no longer reviewed. But probably at that stage it is expected that you're experienced enough to judge whether the edit is useful enough and whether it is worth bumping the question for this change.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you are not sure whether your edits are ok you can also ask in chat, specifically the room named &lt;a href=&quot;https://chat.stackexchange.com/transcript/10243&quot;&gt;MO editor's lounge&lt;/a&gt; seems to be a reasonable place. (Admittedly, the room is currently not visited by many users, so it is possible that you end up without any response. But there were a few discussions related to this in that room. You can find some of them &lt;a href=&quot;https://chat.stackexchange.com/rooms/info/10243/mo-editors-lounge?tab=conversations&quot;&gt;among bookmarked conversations&lt;/a&gt;.) I will also add a link to the &lt;a href=&quot;https://meta.mathoverflow.net/questions/355/specialized-chat-rooms/662#662&quot;&gt;post announcing creation of this room&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What kind of edits should I do and in which way?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;While the intention to improve the site by editing posts is certainly nice, it is good to be aware of adverse effects. The main problem is that any edit &lt;a href=&quot;https://meta.mathoverflow.net/tags/bumping/info&quot;&gt;bumps&lt;/a&gt; the question to the front page. If old posts are moved there, that pushes the most recent post from the front page and they receive less attention.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Do not edit many old posts a once.&lt;/em&gt; For these reasons, it is better not to bump too many old posts at the same time. Recommendation given here in meta is to restrict yourself to editing &lt;a href=&quot;https://meta.mathoverflow.net/q/599#604&quot;&gt;at most 3 edits of old posts&lt;/a&gt; per day. But probably it is better to go a bit lower that this in the case of less experienced users just to be on the safe side.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You can also check whether some old posts has been recently bumped by other users by &lt;a href=&quot;https://mathoverflow.net/search?tab=active&amp;amp;q=created%3a2009-01-01..2018-01-01&quot;&gt;searching for posts and limiting the date range&lt;/a&gt;. So, for example, if you see that several old posts have been bumped during last hour or two, maybe you can leave your edit for later - so that you do not bump even more old posts.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course, the situation is different for posts that are new and posts the were recently bumped for other reasons. (If several edits cause bumping of a question, it is definitely better if they are made at approximately the same time than to see the question bumped several times, each time month or two apart.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;If possible, improve more things.&lt;/em&gt; If you want to edit a post, try to look whether you can make also other improvements to the question and the answers. The reasoning is the same as above - in this way several edits/improvements will bump the question only once.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;An it's quite natural that there is a difference between a minor edit which makes only cosmetic changes and the edit which, for example, &lt;a href=&quot;https://meta.mathoverflow.net/questions/598/list-of-recurrent-technical-problems-involving-mathjax&quot;&gt;corrects completely broken MathJax&lt;/a&gt; or replaces &lt;a href=&quot;https://meta.mathoverflow.net/questions/3158/apologies-re-image-links-update-bumping&quot;&gt;dead link to an image included in the post&lt;/a&gt;. Edits like this are definitely more important than correcting spelling/grammar or something similar.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Where can I find more about this issue?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There were several discussions about this here on meta (and before that on &lt;a href=&quot;https://meta.mathoverflow.net/tags/tea/info&quot;&gt;tea&lt;/a&gt;). Having a look at those discussion could help you get the feeling what users of this site think about various types of edits:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://meta.mathoverflow.net/q/169&quot;&gt;What's our consensus on people resurrecting old questions just to edit formatting?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://meta.mathoverflow.net/q/591&quot;&gt;Editing titles to include $\mathfrak{LaTeX \; Math}$&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://meta.mathoverflow.net/q/599&quot;&gt;Do we have an unofficial quota on how many old questions one should bump for minor edits in a single day?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://meta.mathoverflow.net/q/3030&quot;&gt;Is it worth editing old posts to add links for references?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Of course, there is much more about this on meta.

Please write an edit, explaining the modifications you made.&lt;/i&gt; – Francesco Polizzi Mar 6 at 10:25 &lt;/p&gt;&#xA;&#xA;&lt;p&gt;[e] &lt;i&gt; I disagree with you. Even if this corresponds to the original formulation, this does not deserve an answer, but rather an comment saying that the question should be reformulated.

At any rate, this was the question, it was unanswered, open for more than one hour and it also had un upvote. Sometimes it happens in life that people miss trivial counterexamples, this is not my fault.&lt;/i&gt; – Francesco Polizzi Mar 6 at 13:21 &lt;/p&gt;&#xA;&#xA;&lt;p&gt;[g] &lt;i&gt;That said, I still think that modifying a question with an answer, making a right answer a wrong one is a bad practice, regardless if someone finds such an answer interesting or not.&lt;/i&gt; – Francesco Polizzi Mar 6 at 13:22&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Now let me comment further. I think (1) it's bad practice to modify a question after it's been replied, because it's a lack of respect towards the person who did the answer, who possibly did some efforts to handle the question. In a sense, it reflects that the OP does not consider the efforts made by the person who wrote the answer as worthwhile. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;But it turns out that this judgement can be appropriate, when the answer consists of a trivial counterexample or just a link. (In my own experience, a case with possibly a little effort by the replier, and where the question was subsequently modified, is &lt;a href=&quot;https://mathoverflow.net/a/249402/14094&quot;&gt;this answer&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Next, I think and it's been discussed at many places, that (2) it's bad practice to post trivial answers to trivial questions (one reason among other being that it forbids the OP to delete the question; one other being to discourage homework questions - anyway it's not the point here). If a question has a trivial answer, it should be closed, and the trivial answer should be mentioned in the comments. If one can give to the OP the benefit of the doubt that there's a missing hypothesis, then it's better post a comment addressing this, rather than immediately voting to close.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If we had followed Francesco's request ([d] above) in the current case, what would have happened would be: &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;a new post would have been done with the question excluding finite spaces &lt;/li&gt;&#xA;&lt;li&gt;As regards the original post, Francesco's answer would have been accepted, while the post would have been closed as off-topic.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;" OwnerUserId="14094" LastEditorUserId="14094" LastEditDate="2018-03-09T14:17:51.933" LastActivityDate="2018-03-09T14:17:51.933" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

This has saved me a &lt;em&gt;lot&lt;/em&gt; of time and pain in the past.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Noticing simple examples often requires a lot of serious intuition and expertise in a subject, so it's generally not the case that the answerer is getting undeserved reputation.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;The main reason to modify the question instead of accepting the trivial answer is to avoid polluting your question list with what turned out to be a slightly silly question.  But taking that hit carries significant possible upsides for others.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course my arguments don't apply if the error is so trivial that it requires no real expertise to spot it - e.g. forgetting to exclude zero in a nontrivial question about prime factorizations.  Those issues should be settled in the comments.  But I could see a reasonable person (myself included) spending a bunch of time trying to prove the statement in your original question before running into the two point counter-example, so I would have kept it around for posterity and asked a new question.&lt;/p&gt;&#xA;" OwnerUserId="4362" LastActivityDate="2018-03-22T20:47:20.717" CommentCount="6" ContentLicense="CC BY-SA 3.0" />

And targeting a specific user with multiple downvotes is definitely a bad thing to do and it can in fact lead to a suspension of the serial downvoter.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;But there already are mechanisms that try to catch such instances automatically. For instance, in this specific case you can see &lt;a href=&quot;https://mathoverflow.net/users/8628/dominic-van-der-zypen?tab=reputation&quot;&gt;on the OPs reputation tab&lt;/a&gt; reputation change +6 on April 8 2018 with the description: &quot;Voting corrected (&lt;a href=&quot;https://mathoverflow.net/help/serial-voting-reversed&quot;&gt;learn more&lt;/a&gt;)&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/GDzI6.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/GDzI6.png&quot; alt=&quot;Screenshot from the reputation tab&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In the cases where the automated script does not revert the downvotes even after some time has passed and you still suspect that you have been targeted, you can flag for moderators' attention. Moderators have some additional tools to investigate and they can also ask Stack Exchange staff for help.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Links to some basic information about this can be found &lt;a href=&quot;https://meta.mathoverflow.net/tags/serial-voting/info&quot;&gt;in the serial-voting tag info&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Having said that, I disagree with the proposed feature request:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;I think a mechanism should be installed that no user $u$ can downvote more than one post with a positive score of another user $v$. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I think that there are situations where downvotes are legitimate. Implementing your suggestion (or something similar) would restrict possibility to downvote. And it strengthens the asymmetry between downvotes and upvotes. (There already is some asymmetry in that downvotes have lesser effect on the reputation of the poster than upvotes. Moreover, for a downvote on an answer the downvoter has to &quot;pay&quot; one reputation point. And only &lt;a href=&quot;https://mathoverflow.net/help/privileges/vote-down&quot;&gt;users with repuation above 125&lt;/a&gt; can vote down, while &lt;a href=&quot;https://mathoverflow.net/help/privileges/vote-up&quot;&gt;only 15 reputation points&lt;/a&gt; are required to be allowed to vote up.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In fact, this might have the opposite effect and lead some users to be more prone to downvoting, after thinking along these lines: &quot;Well, this post is borderline, some users might upvote it, some users might downvote it, some might even vote to close or delete. I should better downvote it quickly - if somebody else upvotes it, it might be possible that I am no longer allowed to downvote.&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;And the criterion as described in your post is rather unclear. This question is a good example. If you &lt;a href=&quot;https://meta.mathoverflow.net/posts/3685/timeline&quot;&gt;look at the timeline&lt;/a&gt; then you can see how the score of this question evolved. Namely the post went from $0$ to $-2$ (two downvotes on April 7), then to $+1$ (after three upvotes on April 8) and it is currently back at zero.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you suggest that system should check downvotes on the questions with positive score, how would this question count? After the score flipped from negative to positive, what would happen to the downvotes cast before that?  &lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2018-04-16T04:37:44.777" LastActivityDate="2018-04-16T04:37:44.777" CommentCount="1" ContentLicense="CC BY-SA 3.0" />

So it is not good to use MathJax to achieve strikethrough. (MathJax also gives information which part is mathematical formula and which part is text. This information is used, for example, by &lt;a href=&quot;https://en.wikipedia.org/wiki/Screen_reader&quot; rel=&quot;nofollow noreferrer&quot;&gt;screen readers&lt;/a&gt;, by search engines that specialize in search for mathematical formulas, etc. In general, it is better to avoid mixing between syntax and semantics, between formatting and marking type of text - in this case distinguishing between mathematics and normal text.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Some related posts from the past:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;MathOverflow Meta: &lt;a href=&quot;https://meta.mathoverflow.net/q/2314&quot;&gt;Using MathJax for formating (&lt;strong&gt;bold&lt;/strong&gt;, &lt;em&gt;italics&lt;/em&gt;)?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;Mathematics Meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/17496&quot;&gt;Would HTML/Unicode formatting cause troubles?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;If you want to strike out some part of the text, use &lt;code&gt;&amp;lt;s&amp;gt;...&amp;lt;/s&amp;gt;&lt;/code&gt;. The disadvantage is that it skips formulas, but otherwise I think it is clear.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I would advise &lt;em&gt;against&lt;/em&gt; using MathJax &lt;em&gt;for the purposes&lt;/em&gt; you want to use to link it in your question, i.e., to strike through a long text. (Of course, there are still reasonable uses when this command can be used as part of mathematical formula.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Example: &lt;code&gt;&amp;lt;s&amp;gt;This is merely an example text but ... &amp;lt;/s&amp;gt;&lt;/code&gt;&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&lt;s&gt;This is merely an example text but I was too lazy to copy lorem ipsum from somewhere.

It is the preeminent internet clearinghouse for questions of this nature, and the community here would like to keep it that way and with that specific (high-level) focus. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Your question at the main site is not at that same high level, and so it was closed. MathOverflow is not a site where everyone can get an answer to their mathematics question. Our audience consists largely of busy professionals who don't expect and don't want to see the site overrun by questions at or below the undergraduate level; in fact they would likely leave in droves if that happened. They come here for a reason. This answers your 1. and 3. and I think 4. as well. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Generally speaking, you should always try first to understand the norms and expectations of any well-established internet community, spending perhaps a few days looking at their site and getting a sense of it. Rather than first angrily demanding to know why the community doesn't cater to your idea of what their site should be like. Thus your 2. is, to say it bluntly, ridiculous. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As for 5.: I honestly don't think you are in a position to judge what sorts of things a researcher in professionalized mathematics would find useful; sorry. The closure of your specific question suggests strongly that the community just doesn't view it as useful for the site.

I think that having a large volunteer team address such questions quickly and politely would incur the greatest benefit to the reputation of the forum.  This is why I spend roughly 10% of my responses in telling some that this is the wrong forum for their question, and for most of those a hint or two as to where to go and what to think regarding their question.

Or the combinations of &lt;a href=&quot;https://mathoverflow.net/search?q=user%3A6094+is%3Aq+%5Bpr.probability%5D+%5Bmg.metric-geometry%5D&quot;&gt;tags pr.probability and mg.metric geometry&lt;/a&gt;. (And of course, you can again add other keywords to the search restricted just by tags.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Of course, if you recall more information about the question, you can improve your search. For example, if you remember who answered the question, you can try among the answers of this user. (To search among answers you can use &quot;is:a&quot;. For example, if somebody looks for the same questions and they remember that it was answered by Benoît Kloeckner, they might try to search among &lt;a href=&quot;https://mathoverflow.net/search?q=user%3A4961+is%3Aa+%5Bpr.probability%5D&quot;&gt;answers by this user in some related tag&lt;/a&gt;.) In fact, if you remember one of the answerers, you can combine this with the fact that you are searching among your questions - this cannot be done using the internal search engine, but you can still use data explorer (SEDE) for this.

(At the moment, the new questions are usually retagged by some users. And since not too many new questions have some of the deprecated tags, it seems that the users who do this are doing quite a good job. Still, if addition of deprecated tags is prevented by software, those users could direct their energy to other - possibly more useful - activities.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;A possible solution to this problem could be blacklisting those tags. I will stress that blacklisting a tag does not mean that at the same time the tag has to be removed from all questions.&lt;sup&gt;3&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Blacklisting causes that the tag cannot be added to new questions and when a question with a blacklisted tag is edited, the edit cannot be saved with this tag still included. In both cases, a warning is displayed - it can be a generic message used for blacklisted tags, but it can also be customized. So in this case it might be reasonable to list some of the most common related tags in the text of this warning. (In fact, including tag warnings for deprecated tags has already been suggested before: &lt;a href=&quot;https://meta.mathoverflow.net/q/2798&quot;&gt;Tag warnings on MO&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Some basic information about blacklisted tags can also be found &lt;a href=&quot;https://meta.mathoverflow.net/tags/blacklisted-tags/info&quot;&gt;in the corresponding tag-info&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Proposal:&lt;/strong&gt; Let us blacklist the tags which are deprecated but still exist on the site. In the future, if some other big tags are deprecated, blacklisting should be considered as well. (At least in the cases when the removal of the tags is likely to take a long time.) &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;NOTE: This post is not intended for discussion whether or not those tags indeed should be deprecated. When I look at the tag excerpts, I see that information that the tag is deprecated was added in March 2016 for &lt;a href=&quot;https://mathoverflow.net/posts/233412/revisions&quot;&gt;abstract-algebra&lt;/a&gt;, in February 2016 for &lt;a href=&quot;https://mathoverflow.net/posts/230820/revisions&quot;&gt;discrete-mathematics&lt;/a&gt; and in June 2013 for &lt;a href=&quot;https://mathoverflow.net/posts/134828/revisions&quot;&gt;geometry&lt;/a&gt;. So the decision that these tags are deprecated were made quite a long time ago and this can be considered established practice. (If somebody thinks that some of these tags should not be deprecated or wants to know more about the reasons why there are deprecated, it would be better to make a separate post for such discussion.)&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;Theoretically moderators could request from SE staff to &lt;a href=&quot;https://meta.stackexchange.com/tags/tags-burnination/info&quot;&gt;burninate the tags&lt;/a&gt; or they could merge them &lt;a href=&quot;https://mathoverflow.net/tags/tag-removed/info&quot;&gt;into (tag-removed)&lt;/a&gt;. So hypothetically it is possible to remove all instances of a specific tag without bumping any old questions. However, for big tags such removal would likely end up with many questions missing relevant tags and being tagged incorrectly. I suppose that this is the reason why some tags are still kept despite being deprecated. (But I was unable to find something here on meta where this was discussed in detail.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;At the moment there are &lt;a href=&quot;https://mathoverflow.net/questions/tagged/abstract-algebra+or+discrete-mathematics+or+geometry&quot;&gt;about 900 questions&lt;/a&gt; with deprecated tags. (At least the ones &lt;a href=&quot;https://meta.mathoverflow.net/questions/3261/what-is-the-correct-way-to-handle-questions-with-deprecated-tags&quot;&gt;I am aware of&lt;/a&gt;.) Considering that there were 1000 such questions in August 2017, the number is not decreasing very fast.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In fact, it seems that the main contributing factors to the decrease was that the number of questions in &lt;a href=&quot;https://mathoverflow.net/questions/tagged/geometry&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;geometry&amp;#39;&quot; rel=&quot;tag&quot;&gt;geometry&lt;/a&gt; tag dropped. This was partly thanks to bunch of retags made by François G. Dorais. And partly thanks to the fact that some questions were bumped in order to replace images that were no longer displayed. And after those questions were bumped, quite often also the deprecated (geometry) tag was replaced by more suitable tags. (For example, &lt;a href=&quot;https://meta.mathoverflow.net/q/3158&quot;&gt;Joseph O'Rourke and j.c.&lt;/a&gt; updated images in many of their own posts. And I have also seen several such edits by jeq - if you check &lt;a href=&quot;https://mathoverflow.net/users/16302/jeq?tab=activity&amp;amp;sort=revisions&quot;&gt;list of their edits&lt;/a&gt;, you can find several such edits - just search for the edit summary containing: &quot;Copied image to imgur.com, as it was not being displayed because of the new https rule&quot;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In case somebody is interested in more detailed stats, you can check them &lt;a href=&quot;https://chat.stackexchange.com/rooms/10243/conversation/how-fast-are-deprecated-tags-getting-removed&quot;&gt;here in chat&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;3&lt;/sup&gt;In fact, for a long time I did not know that blacklisting is possible even without removal of all instances of the tag. I find out about this only after Asaf Karagila posted this feature request on Mathematics Meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/28025&quot;&gt;Can we please have a “deprecated tag” feature?&lt;/a&gt;&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2018-05-10T11:09:28.907" LastActivityDate="2018-05-10T11:09:28.907" Title="The existing deprecated tags should be blacklisted" Tags="|discussion|tags|blacklisted-tags|" AnswerCount="0" CommentCount="7" ContentLicense="CC BY-SA 4.0" />

Better from a strictly stackexchange model point of view (although there are gray areas here) is thank the answer-poster, but then ask a new question with a link to the old, where you ask what you now realize you're really after.

An example is that certain behaviours like saying &quot;Thank You&quot; are considered disadvantageous for some fora (who prefer maximum rate of information transfer per character) and permissible for others (those who want to encourage a certain tone or atmosphere of acceptance and acknowledgement).  If you participate in several fora, it is a good idea to check what color mud to rub in ones navel when participating. (Check the local standards.).

And I'd guess most users know this feature under the name favorite tags. (Maybe it was called differently at the time when the default tags were selected.) I think that average user would have hard time guessing what (interesting-tags) is intended for. Which might lead to inconsistent usage of this tag and some incorrectly tagged questions. (As you can see &lt;a href=&quot;https://chat.stackexchange.com/transcript/10243/2018/5/19&quot;&gt;in this chat transcript&lt;/a&gt; the tag has been used on some question on meta - &lt;a href=&quot;https://meta.mathoverflow.net/posts/3615/revisions&quot;&gt;here&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/posts/2798/revisions&quot;&gt;here&lt;/a&gt; - and in neither of the two cases in the intended meaning.

(With (favorite-tags) as the master tag. This would basically copy the usage on Meta Stack Exchange.)&lt;/li&gt;&#xA;&lt;li&gt;Another option would be to create a tag synonym &lt;a href=&quot;/questions/tagged/interesting-tags&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;interesting-tags&amp;#39;&quot; rel=&quot;tag&quot;&gt;interesting-tags&lt;/a&gt; $\to$ &lt;a href=&quot;/questions/tagged/favorites&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;favorites&amp;#39;&quot; rel=&quot;tag&quot;&gt;favorites&lt;/a&gt; and use (favorites) both for favorite questions and favorite tags.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;If you look at current usage of the tag &lt;a href=&quot;/questions/tagged/favorites&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;favorites&amp;#39;&quot; rel=&quot;tag&quot;&gt;favorites&lt;/a&gt; and also if you check current revision of &lt;a href=&quot;https://meta.mathoverflow.net/posts/3102/revisions&quot;&gt;the tag-excerpt&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/posts/3101/revisions&quot;&gt;the tag-wiki&lt;/a&gt;, you can see that this tag is currently used for both favorite tags and favorite question. (I am partly to blame - I have used the tag in this way and also I have created the tag-info. However, it seemed to me a bit redundant to create a separate tag for favorite tags.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This means that if we decide to have a separate tag for &lt;a href=&quot;/questions/tagged/favorite-tags&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;favorite-tags&amp;#39;&quot; rel=&quot;tag&quot;&gt;favorite-tags&lt;/a&gt;, this would require also retagging of a few older questions.

(See also this post on Meta Stack Exchange: &lt;a href=&quot;https://meta.stackexchange.com/q/251354&quot;&gt;Will my deleted accounts be linked?&lt;/a&gt;) In this specific case I was able to find &lt;a href=&quot;https://webcache.googleusercontent.com/search?q=cache:https://math.stackexchange.com/users/537668/cello&quot; rel=&quot;nofollow noreferrer&quot;&gt;Mathematics profile&lt;/a&gt; and &lt;a href=&quot;https://webcache.googleusercontent.com/search?q=cache:https://mathoverflow.net/users/100241/&quot; rel=&quot;nofollow noreferrer&quot;&gt;MathOverflow profile&lt;/a&gt; of this user in Google Cache. (In both cases, the cached version is from 15 March 2018.

In fact, sometimes in these situations we see a good synergy in the answers, as each one addresses to a single question and gives a spark to the remaining. But judging  analogies  is a delicate matter; some posters may like to ask about more facts at once, because some analogy suggests them a deeper connection. Is it right to split a priori  such  a multi-question just because we think there is no connection at all? I'm not sure. &#xA;So I would first of all recommend the questioners to explain clearly the link between their questions, or at least why they think there is a connection.

  <row Id="3762" PostTypeId="2" ParentId="3751" CreationDate="2018-06-12T11:45:02.077" Score="2" Body="&lt;p&gt;&lt;sup&gt;The question is getting close to two weeks old (after that it will no longer be displayed in community bulletin, which means that it will be noticed by less users than it is now - which also decreases likelihood of getting some feedback) and so far nobody responded - if we do not count a few comments, most of which seem to be related closer to the question linked as an example rather than to the general issue the OP asks about. Let me try to address at least some points raised in the question. Of course, it would be definitely better to get some response from more experienced MathOverflow users. And perhaps also from moderators - since one of your suggestions was to flag for moderator's attention in the situation described in the question. So take this as a response of somebody who has more experience with reopen process and community moderating from other sites. Although MathOverflow is in some aspects unique, at least some things work in the same way as on other sites, so some experience from other sites in the Stack Exchange network is transferable.&lt;/sup&gt;&lt;/p&gt;&#xA;&lt;h3&gt;What can be done with the already existing tools?&lt;/h3&gt;&#xA;&lt;p&gt;Stack Exchange software already has several features that help with reopening question. Maybe I should start by linking to the Help Center: &lt;a href=&quot;https://mathoverflow.net/help/reopen-questions&quot;&gt;What if I disagree with the closure of a question? How can I reopen it?&lt;/a&gt; and the relevant FAQ item: &lt;a href=&quot;https://meta.stackexchange.com/q/36415&quot;&gt;How do you reopen a closed question?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Reopen review queue.&lt;/strong&gt; This is probably the most relevant thing for this purpose. There are several &lt;a href=&quot;https://meta.mathoverflow.net/tags/review-system/info&quot;&gt;review queues&lt;/a&gt;, in connection with reopening the &lt;a href=&quot;https://mathoverflow.net/review/reopen/&quot;&gt;reopen votes review queue&lt;/a&gt; is relevant. Users with sufficient reputation can evaluate here some questions and choose either to leave them close or vote to reopen (or they can simply skip the review and leave the decision for other users if they are unsure). According to &lt;a href=&quot;https://meta.stackexchange.com/q/256060#256071&quot;&gt;this answer&lt;/a&gt; a question gets into this queue if: 1. Somebody votes to reopen. 2. Body of question is edited with 5 days of being put on hold (the exact conditions can be found &lt;a href=&quot;https://meta.stackexchange.com/q/196074#196078&quot;&gt;in this answer&lt;/a&gt;). 3. Question is &amp;quot;popular&amp;quot; (which is calculated using votes and views). I'd guess that the first two options are relevant for the situation you described in the question.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Users can check their votes and also recent reopen votes.&lt;/strong&gt; Every user can check their past votes on their &lt;a href=&quot;https://mathoverflow.net/users/current?tab=votes&quot;&gt;votes tab&lt;/a&gt;. In particular, they can check their past &lt;a href=&quot;https://mathoverflow.net/users/current?tab=votes&amp;amp;sort=downvote&quot;&gt;downvotes&lt;/a&gt; and their past &lt;a href=&quot;https://mathoverflow.net/users/current?tab=votes&amp;amp;sort=closure&quot;&gt;close votes&lt;/a&gt; - and if they see some improvements, they can reconsider. (Either vote to reopen or remove the downvote.)&lt;/p&gt;&#xA;&lt;p&gt;Users with &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;10k+ reputation&lt;/a&gt; have access to &lt;a href=&quot;https://mathoverflow.net/tools&quot;&gt;moderator tools&lt;/a&gt; where they can see recent reopen votes - they can have a look and if the question is worth reopening, they can also vote to reopen. At the same reputation level, users gain access to full review history. In particular, for reopening questions this means that a user can check which questions have been in the &lt;a href=&quot;https://mathoverflow.net/review/reopen/history&quot;&gt;reopen review queue recently&lt;/a&gt; and for the ones that were not reopened, they can have a look and decide for themselves whether they want to add a reopen vote.&lt;/p&gt;&#xA;&lt;p&gt;It is quite likely that there are not many users who actually do this. But your question can be considered as an encouragement to do this more often. (And, after all, it is not necessary that the same users who voted to close are the ones who vote to reopen. So if the question gets to attention to some other users, it still has a good chance that it might get reopened if it was improved.)&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Reopen request thread.&lt;/strong&gt; There is a &lt;a href=&quot;https://meta.mathoverflow.net/q/223&quot;&gt;reopen request thread&lt;/a&gt; here on meta. If the question is not reopened through the review queue and you think it should be reopened, it is very reasonable to post an answer there. This can attract attention of other users to the question. And the advantage is that some short discussion is possible in the comments - if other users disagree, they can layout their arguments why the post should not be reopened. (In the reopen review queue the users have to rely on what they see in the question and in the comments. In this thread, the case for reopening can be presented more clearly.)&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Separate chatroom?&lt;/strong&gt; On some sites there is a separate chatroom with deals with stuff like closing and reopening. For example, &lt;a href=&quot;https://chat.stackoverflow.com/rooms/info/41570/so-close-vote-reviewers&quot;&gt;SOCVR&lt;/a&gt; on Stack Overflow (here is &lt;a href=&quot;https://socvr.org&quot; rel=&quot;nofollow noreferrer&quot;&gt;the room's website&lt;/a&gt; where you can learn a bit more about it) or &lt;a href=&quot;https://chat.stackexchange.com/rooms/info/2165/crude&quot;&gt;CRUDE&lt;/a&gt; on Mathematics (here is &lt;a href=&quot;https://math.meta.stackexchange.com/questions/26814/list-of-chatrooms/26816#26816&quot;&gt;a short description&lt;/a&gt; of the room). They deal predominantly with closures, but you can find also questions that were reopened based on discussion in those rooms.&lt;/p&gt;&#xA;&lt;p&gt;However, I do not think that creating a chatroom for this purpose would be suitable solution for MathOverflow &lt;em&gt;at this moment&lt;/em&gt;. We are talking here about big sites, that have much bigger number of questions than MathOverflow and close votes review is almost constantly clogged up with hundreds of posts waiting for review. It is natural that in such situation users are looking for additional mechanisms to help with moderating the site (which includes closing and reopening) - but this is not the case here. And also, since those sites are bigger, they also have many users willing to devote some time to help with closing/reopening and other janitorial tasks. Moreover, with the exception of Homotopy Theory chatroom there is not much activity in &lt;a href=&quot;https://chat.stackexchange.com/?tab=site&amp;amp;host=mathoverflow.net&quot;&gt;rooms associated with MO&lt;/a&gt; so it is not clear whether this one would gain more activity than the existing ones. But if somebody feels that a room like that might be useful here, they can certainly create such room and see how it works out. Mentioning the new room in &lt;a href=&quot;https://meta.mathoverflow.net/questions/355/specialized-chat-rooms&quot;&gt;the designated thread&lt;/a&gt; might improve the chances that it gets noticed.&lt;/p&gt;&#xA;&lt;h3&gt;Should there be some kind of notification for close voters?&lt;/h3&gt;&#xA;&lt;p&gt;Let me first point out that I have noticed in the linked example there is a comment of the form: &amp;quot;@username I guess, it got reasonably clear now, so I voted to reopen. What do you think?&amp;quot; (It was the username of the first close voter.) This actually does not notify the user (unless they already made a comment or edited the post). The only case when close voters can be notified is if the question was closed by a single user - which means either the first and the only close voter was either a moderator or gold tag badge owner's (the latter only in case of duplicates). There is a feature request related to this: &lt;a href=&quot;https://meta.stackexchange.com/q/81849&quot;&gt;If you put @username in a comment to a question, does it contact editors/voters?&lt;/a&gt; In order not to go too much into technicalities I will just add that links to some places containing the details on how to comment replies work can be found &lt;a href=&quot;https://meta.mathoverflow.net/tags/comment-notification/info&quot;&gt;in the corresponding tag-info&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;It seems that your main suggestion was to implement notification to close voters if the question was edited. There is a similar feature request on Meta Stack Exchange: &lt;a href=&quot;https://meta.stackexchange.com/q/56849&quot;&gt;Notify close voters when a closed question gets edited&lt;/a&gt;. Currently it is at score 43 (48 upvotes/5 downvotes). So if you feel that this is good idea, than you should upvote that feature request to improve its chances. (My personal objection to this is that it might result into having too many notifications. But I do not feel about this strongly enough to downvote the feature request.)&lt;/p&gt;&#xA;&lt;h3&gt;Is it useful to flag such posts for moderators' attention?&lt;/h3&gt;&#xA;&lt;p&gt;Well, probably it would be best to &lt;em&gt;hear from moderators&lt;/em&gt; what they think about this.&lt;/p&gt;&#xA;&lt;p&gt;The &lt;a href=&quot;https://mathoverflow.net/help/reopen-questions&quot;&gt;Help Center&lt;/a&gt; explicitly mentions: &amp;quot;If a moderator (user with a ♦ symbol after their name) closed the question, then you may flag it for moderator attention. Again, do this only after editing and include a detailed explanation of why it should be reopened. There is more than one moderator, and moderators do reconsider their decisions.&amp;quot; But this is somewhat different situation from what you have described in the post. It seems that there is no clear consensus about this also among mods throughout the network, judging by the fact that this question has no answers: &lt;a href=&quot;https://meta.stackexchange.com/q/284732&quot;&gt;How should moderators handle a custom flag to re-open a question?&lt;/a&gt; There are a few posts which recommend flagging for moderators' attention only as the last resort after other options have been exhausted or directly advise against it: &lt;a href=&quot;https://meta.stackexchange.com/q/215371#215375&quot;&gt;How to seek attention to reopen a closed question?&lt;/a&gt; or &lt;a href=&quot;https://meta.stackexchange.com/q/300673#300675&quot;&gt;Should I flag my closed question after editing to receive attention?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;It is also probably a matter of frequency. Let's assume that flags for this reason would be cast with similar frequency as reopen reviews. I was only able to find only four reopen reviews within a scope of approximately a week. (I found these reviews: &lt;a href=&quot;https://mathoverflow.net/review/reopen/100908&quot;&gt;100908&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/review/reopen/100784&quot;&gt;100784&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/review/reopen/100675&quot;&gt;100675&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/review/reopen/100641&quot;&gt;100641&lt;/a&gt;. Since I do not have sufficient reputation to see the reopen review history, it's a bit more difficult for me to look for such reviews. But I am still pretty confident that the actual numbers are not much higher.) Moderators would be certainly able to handle four more flags a week. But if we look, for example, on Mathematics, where number for reopen reviews per week are closer to 100, that would be IMO a non-negligible addition to the number of flags that moderator have to deal with.&lt;/p&gt;&#xA;&lt;p&gt;My main problem with the suggestion that in such cases reopening should be requested from moderators is that on a good functioning site, the site moderation should be done &lt;em&gt;by the community&lt;/em&gt; as much as possible.&lt;sup&gt;1&lt;/sup&gt; It is clear there are some situations where moderators have to step in. If a question is closed and reopened for the tenth time, or if some edit is repeatedly done and undone, they step in. They also deal with account suspensions for problematic users. And they do many other things which for us - the regular users - remain under the surface and we do not seen them. I think they should be helped by other users where possible.&lt;/p&gt;&#xA;&lt;p&gt;Another issue is that moderator votes to close/reopen have an immediate effect. While it takes 5 votes from regular users to close/reopen (with some minor exceptions), a single vote by a mod suffices. Of course, a moderator has every right to vote to close/reopen if they think the question should be closed/reopened. By they probably still keep in mind that they can do this singlehandedly and are therefore a bit more careful with such actions. Here is what one of the current moderators said about this during &lt;a href=&quot;https://meta.mathoverflow.net/q/980#984&quot;&gt;2013 Moderator Election&lt;/a&gt;:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;I am of the position that mods should not be editors of the site. We have a considerable number of users with essentially the same powers as moderators with respect to closing/deleting/etc (except, of course, that mods votes to do such things is immediately binding) and it is they who should be doing the closing, deleting and so on.&lt;/p&gt;&#xA;&lt;p&gt;As a mod on M.SE I vote, in fact, much less to close/delete/&amp;amp;c than when I was a `regular' user (It should be observed that a mod cannot turn off his modhood) and I restrict those actions to obvious spam and other matters which require immediate action.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;Let me digress a bit to say a few words about &lt;em&gt;reputation&lt;/em&gt;. From the viewpoint of a user, perhaps reputation is importation as it brings gamification aspect and also user might enjoy that they can use moderation for bounties in hope to attract attention to some question. But for the site as a whole it is useful as a measure of experience of particular user with the site. Perhaps it is rather inexact measure, but it is definitely at least a reasonable estimate. Therefore it makes sense that various &lt;a href=&quot;https://mathoverflow.net/help/privileges/close-questions&quot;&gt;privileges&lt;/a&gt; are awarded based on reputation. And with them users gets more and more additional ways how they can help the site, if they are willing to do so. For example, it would not make much sense to put reopen review in front of a user who is here for the first day and thinks that question asking to solve &lt;span class=&quot;math-container&quot;&gt;$\lim_{n\to\infty} (\sqrt{n^2+n}-n)$&lt;/span&gt; is a perfectly reasonable question for this site. Somebody who is &lt;a href=&quot;https://mathoverflow.net/help/privileges/close-questions&quot;&gt;at 3000 reputation points&lt;/a&gt; has already spent enough time on the site and is able to judge whether a question is suitable for reopening.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="-1" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2018-06-13T08:00:29.077" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

The syntax is basically &lt;a href=&quot;https://en.wikipedia.org/wiki/LaTeX&quot; rel=&quot;nofollow noreferrer&quot;&gt;LaTeX&lt;/a&gt;, so if you are already familiar with TeX or LaTeX you should be fine. (It is worth keeping in mind that only stuff that can be used inside math mode works in MathJax too.&lt;sup&gt;1&lt;/sup&gt;)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is useful to know that you can learn some parts of the syntax also from posts by other users. If you see a formula, right click gets you to MathJax context menu. By choosing &quot;Show Math As &gt; TeX Commands&quot; you can see the source which you can use to typeset formulas.&lt;sup&gt;2&lt;/sup&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;The mathematical formulas are enclosed in dollars. If you want a centered formula, you can use double dollars. For example &lt;code&gt;$a^2-b^2=(a-b)(a+b)$&lt;/code&gt; and &lt;code&gt;$$\frac{a^2-b^2}{a-b}=a+b$$&lt;/code&gt; gives &lt;span class=&quot;math-container&quot;&gt;$a^2-b^2=(a-b)(a+b)$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$$\frac{a^2-b^2}{a-b}=a+b$$&lt;/span&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Here is an overview of some basic commands, mainly through examples. If you need more than what is listed in this very basic overview, you can consult some of the resources linked in &lt;a href=&quot;https://meta.mathoverflow.net/questions/3763/how-does-one-type-mathematical-formulas-on-this-site/3765#3765&quot;&gt;another answer to this question&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;Superscripts, indices: You can use &lt;code&gt;^&lt;/code&gt; for superscripts and &lt;code&gt;_&lt;/code&gt; for subscripts. If it is supposed to contain more than one symbol, then you enclose the content between &lt;code&gt;{..}&lt;/code&gt;. (The same is true in many other cases, not only here.) Examples: &lt;code&gt;$(x_1+\dots+x_n)^2$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$(x_1+\dots+x_n)^2$&lt;/span&gt;, &lt;code&gt;$a^{b+c}=a^b\cdot a^c$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$a^{b+c}=a^b\cdot a^c$&lt;/span&gt; and &lt;code&gt;$F_n=F_{n-1}+F_{n-2}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$F_n=F_{n-1}+F_{n-2}$&lt;/span&gt;. This is how you get double subscripts/superscripts: &lt;code&gt;$a^{b^c}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$a^{b^c}$&lt;/span&gt; and &lt;code&gt;$x_{n_k}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$x_{n_k}$&lt;/span&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Fractions, radicals. Again, if you are using more than one symbol, use &lt;code&gt;{..}&lt;/code&gt; - they are not needed if there is only one symbol. (But you can still use them if you want. For example, &lt;code&gt;$\frac\alpha2$&lt;/code&gt; and &lt;code&gt;$\frac{\alpha}{2}$&lt;/code&gt; give the same result.) Examples: &lt;code&gt;$\frac\alpha2\cdot\frac{2^2}{\alpha^2}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\frac\alpha2\cdot\frac{2^2}{\alpha^2}$&lt;/span&gt;, &lt;code&gt;$\sqrt{x^2+y^2}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\sqrt{x^2+y^2}$&lt;/span&gt;, &lt;code&gt;$\sqrt[3]5$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\sqrt[3]5$&lt;/span&gt;, &lt;code&gt;$\sqrt[n]n\ge\sqrt[n+1]{n+1}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\sqrt[n]n\ge\sqrt[n+1]{n+1}$&lt;/span&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Inequalities: &lt;code&gt;$\ge$&lt;/code&gt; for &lt;span class=&quot;math-container&quot;&gt;$\ge$&lt;/span&gt;, &lt;code&gt;$\le$&lt;/code&gt; for &lt;span class=&quot;math-container&quot;&gt;$\le$&lt;/span&gt; and &lt;code&gt;$\ne$&lt;/code&gt; for &lt;span class=&quot;math-container&quot;&gt;$\ne$&lt;/span&gt;. For strict inequalities you can simply use &lt;code&gt;$&amp;lt;$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$&amp;lt;$&lt;/span&gt; and &lt;code&gt;$&amp;gt;$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$&amp;gt;$&lt;/span&gt;. Examples:&#xA;&lt;code&gt;$xy\le\frac{x^p}p+\frac{x^q}q$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$xy\le\frac{x^p}p+\frac{x^q}q$&lt;/span&gt;&#xA;&lt;code&gt;$f\left(\frac{x+y}2\right)\ge\frac{f(x)+f(y)}2$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$f\left(\frac{x+y}2\right)\ge\frac{f(x)+f(y)}2$&lt;/span&gt;,&#xA;&lt;code&gt;$AB\ne BA$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$AB\ne BA$&lt;/span&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Bracket and parenthesis: Since &lt;code&gt;{..}&lt;/code&gt; have special meaning in MathJax/LaTeX, to get curly brackets you can use &lt;code&gt;$\{..\}$&lt;/code&gt;. Example: &lt;code&gt;$\{x+y; x\in A, y\in B\}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\{x+y; x\in A, y\in B\}$&lt;/span&gt;. Other types of brackets: &#xA;&lt;code&gt;$(x,y)$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$(x,y)$&lt;/span&gt;, &#xA;&lt;code&gt;$[x,y]$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$[x,y]$&lt;/span&gt;, &#xA;&lt;code&gt;$\langle x,y\rangle$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\langle x,y\rangle$&lt;/span&gt;,&#xA;&lt;code&gt;$\lfloor x \rfloor \le \lceil x \rceil$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\lfloor x \rfloor \le \lceil x \rceil$&lt;/span&gt;.&lt;/li&gt;&#xA;&lt;li&gt;It is sometimes useful to change size of brackets, if the content between them is large: &lt;code&gt;$\left(1+\frac1x\right)^x$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\left(1+\frac1x\right)^x$&lt;/span&gt;. The operators &lt;code&gt;\left&lt;/code&gt; and &lt;code&gt;\right&lt;/code&gt; work for other types of parenthesis, too.&lt;/li&gt;&#xA;&lt;li&gt;Sums, products: &lt;code&gt;$\sum_{k=1}^n k = \frac{n(n+1)}2$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\sum_{k=1}^n k = \frac{n(n+1)}2$&lt;/span&gt;; &lt;code&gt;$\prod_{n=1}^\infty (1-x_n)=0$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\prod_{n=1}^\infty (1-x_n)=0$&lt;/span&gt;. Notice that delimiters are displayed differently in centered formulas: &lt;code&gt;$$\sum_{k=1}^n k = \frac{n(n+1)}2$$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$$\sum_{k=1}^n k = \frac{n(n+1)}2$$&lt;/span&gt;&#xA;(To achieve a similar effect in inline formulas you can use &lt;code&gt;\limits&lt;/code&gt; as in &lt;code&gt;$\sum\limits_{k=1}^n k = \frac{n(n+1)}2$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\sum\limits_{k=1}^n k = \frac{n(n+1)}2$&lt;/span&gt;.)&lt;/li&gt;&#xA;&lt;li&gt;Sets: &lt;code&gt;$\in$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\in$&lt;/span&gt;, &lt;code&gt;$\notin$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\notin$&lt;/span&gt;, &lt;code&gt;$\cup$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\cup$&lt;/span&gt;, &lt;code&gt;$\cap$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\cap$&lt;/span&gt;, &lt;code&gt;$\setminus$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\setminus$&lt;/span&gt;. Examples: &lt;code&gt;$A\cap (B\cup C)$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$A\cap (B\cup C)$&lt;/span&gt;, &lt;code&gt;$A\cap B=\{x\in A; x\in B\}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$A\cap B=\{x\in A; x\in B\}$&lt;/span&gt;. You can also use &lt;code&gt;$\bigcup$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\bigcup$&lt;/span&gt; and &lt;code&gt;$\bigcap$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\bigcap$&lt;/span&gt;. Example: &lt;code&gt;$\bigcup_{i\in I} \left(X\setminus A_i\right) = X\setminus \left(\bigcap_{i\in I} A_i\right)$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\bigcup_{i\in I} \left(X\setminus A_i\right) = X\setminus \left(\bigcap_{i\in I} A_i\right)$&lt;/span&gt;. The delimiters work here similarly as for sum and product: &lt;code&gt;$\bigcup\limits_{i=1}^\infty (-n,n)=\mathbb R$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\bigcup\limits_{i=1}^\infty (-n,n)=\mathbb R$&lt;/span&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Some special fonts: &lt;code&gt;$\mathbb N$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\mathbb N$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$\mathbb R$&lt;/span&gt; &lt;code&gt;$\mathbb R$&lt;/code&gt; for blackboard bold. Some other common fonts: &lt;code&gt;$\mathcal B, \mathrm B, \mathfrak B, \mathbf B, \mathscr B$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\mathcal B, \mathrm B, \mathfrak B, \mathbf B, \mathscr B$&lt;/span&gt;&lt;/li&gt;&#xA;&lt;li&gt;Some special symbols &lt;code&gt;$\pm\infty$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\pm\infty$&lt;/span&gt;. &lt;code&gt;$3\mid6$&lt;/code&gt; but &lt;code&gt;$3\nmid 7$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$3\mid6$&lt;/span&gt; but &lt;span class=&quot;math-container&quot;&gt;$3\nmid 7$&lt;/span&gt;, &lt;code&gt;$\vec a$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\vec a$&lt;/span&gt;, &lt;code&gt;$\binom nk = \binom{n}{n-k}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\binom nk = \binom{n}{n-k}$&lt;/span&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Calculus: &lt;code&gt;$\lim_{n\to\infty} \left(1+\frac1n\right)$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\lim_{n\to\infty} \left(1+\frac1n\right)$&lt;/span&gt;, &lt;code&gt;$\int_{-\infty}^\infty e^{-x^2} \,dx = \sqrt{\pi}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\int_{-\infty}^\infty e^{-x^2} \,dx = \sqrt{\pi}$&lt;/span&gt;, &lt;code&gt;$\frac{\partial f}{\partial x}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\frac{\partial f}{\partial x}$&lt;/span&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Greek letters: Simply use &lt;code&gt;$\alpha$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\alpha$&lt;/span&gt;, &lt;code&gt;$\beta$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\beta$&lt;/span&gt;, &lt;code&gt;$\gamma$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\gamma$&lt;/span&gt;, etc. Some of them have two variants: &lt;code&gt;$\epsilon$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\epsilon$&lt;/span&gt; and &lt;code&gt;$\varepsilon$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\varepsilon$&lt;/span&gt;, &lt;code&gt;$\phi$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\phi$&lt;/span&gt; and &lt;code&gt;$\varphi$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\varphi$&lt;/span&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Operators: &lt;code&gt;$\max(a,b)$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\max(a,b)$&lt;/span&gt;, &lt;code&gt;$\min\{a,b\}$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\min\{a,b\}$&lt;/span&gt;, &lt;code&gt;$\sin^2x+\cos^2x=1$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\sin^2x+\cos^2x=1$&lt;/span&gt;, &lt;code&gt;$\ln(1+x)\le x$&lt;/code&gt; &lt;span class=&quot;math-container&quot;&gt;$\ln(1+x)\le x$&lt;/span&gt;. &lt;/li&gt;&#xA;&lt;li&gt;Some examples using matrices:&lt;br&gt;&#xA;&lt;code&gt;$$\begin{pmatrix}&#xA;1 &amp;amp; 2 &amp;amp; 3 \\&#xA;0 &amp;amp; 1 &amp;amp; 4 \\&#xA;4 &amp;amp; 2 &amp;amp; -1&#xA;\end{pmatrix}$$&lt;/code&gt;&lt;br&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$\begin{pmatrix}&#xA;1 &amp;amp; 2 &amp;amp; 3 \\&#xA;0 &amp;amp; 1 &amp;amp; 4 \\&#xA;4 &amp;amp; 2 &amp;amp; -1&#xA;\end{pmatrix}$$&lt;/span&gt;&#xA;&lt;code&gt;$$\left(\begin{array}{cccc|c}&#xA;  1 &amp;amp; 1 &amp;amp; 1 &amp;amp; 1 &amp;amp; 0 \\&#xA;  0 &amp;amp; 1 &amp;amp; 3 &amp;amp; 1 &amp;amp; 2 \\&#xA;  1 &amp;amp; 1 &amp;amp; 3 &amp;amp; 1 &amp;amp; 4 \\&#xA;  1 &amp;amp; 1 &amp;amp; 5 &amp;amp; 4 &amp;amp; 2&#xA;\end{array}\right)$$&lt;/code&gt;&#xA;&lt;span class=&quot;math-container&quot;&gt;$$\left(\begin{array}{cccc|c}&#xA;  1 &amp;amp; 1 &amp;amp; 1 &amp;amp; 1 &amp;amp; 0 \\&#xA;  0 &amp;amp; 1 &amp;amp; 3 &amp;amp; 1 &amp;amp; 2 \\&#xA;  1 &amp;amp; 1 &amp;amp; 3 &amp;amp; 1 &amp;amp; 4 \\&#xA;  1 &amp;amp; 1 &amp;amp; 5 &amp;amp; 4 &amp;amp; 2&#xA;\end{array}\right)$$&lt;/span&gt;&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;Many further details on the differences between the two could be added, but this is probably a reasonable rule of thumb.

I'll try to describe the existing tags - I have also copied the tag-excerpts below.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;At the moment there are these tags:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The top-level tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/ca.classical-analysis-and-odes&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;ca.classical-analysis-and-odes&amp;#39;&quot; rel=&quot;tag&quot;&gt;ca.classical-analysis-and-odes&lt;/a&gt;, which covers ODEs but also several other large areas.&lt;/li&gt;&#xA;&lt;li&gt;The tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/differential-equations&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;differential-equations&amp;#39;&quot; rel=&quot;tag&quot;&gt;differential-equations&lt;/a&gt;, which is (according to the tag-excerpt) both for ODEs and PDEs. (And also for some other types of equations.) This also overlaps with the &lt;a href=&quot;https://mathoverflow.net/questions/tagged/ap.analysis-of-pdes&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;ap.analysis-of-pdes&amp;#39;&quot; rel=&quot;tag&quot;&gt;ap.analysis-of-pdes&lt;/a&gt; tag.&lt;/li&gt;&#xA;&lt;li&gt;There is also the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/analysis-and-odes&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;analysis-and-odes&amp;#39;&quot; rel=&quot;tag&quot;&gt;analysis-and-odes&lt;/a&gt;, but it is hardly used (it contains &lt;a href=&quot;https://chat.stackexchange.com/transcript/10243/2018/6/28&quot;&gt;only five questions&lt;/a&gt;). It has empty tag-info and from the title it is not clear whether this tag was intended to be exclusively about ODEs.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Just for comparison I'll mention that on Mathematics there is a tag called (&lt;a href=&quot;https://math.stackexchange.com/questions/tagged/differential-equations&quot;&gt;differential-equations&lt;/a&gt;). The &lt;a href=&quot;https://math.stackexchange.com/tags/differential-equations/info&quot;&gt;tag-excerpt&lt;/a&gt; explicitly says that it is for ODEs and not PDEs. (This is not exactly area I am active in, but my estimate is that enough experienced users on Mathematics site know about the distinction between this tag and the (&lt;a href=&quot;https://math.stackexchange.com/questions/tagged/pde&quot;&gt;pde&lt;/a&gt;) tag and incorrectly tagged questions are usually quickly retagged.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;What should be done about the tags for ODEs here on MathOverflow?&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Doing nothing is also an option. We have two big tags - (ca.classical-analysis-and-odes) and (differential-equations) - which contain ODEs as one of the topics, maybe a separate tag is not needed. (After all, if the asker includes a top-level tag &lt;a href=&quot;https://meta.mathoverflow.net/questions/1075/frequently-asked-questions-about-tagging-on-mathoverflow/1076#1076&quot;&gt;as recommended&lt;/a&gt;, it should be possible to find questions about ODEs using the combination of the tags &lt;a href=&quot;https://mathoverflow.net/questions/tagged/differential-equations+ca.classical-analysis-and-odes&quot;&gt;differential-equations+ca.classical-analysis-and-odes&lt;/a&gt;.)&lt;/li&gt;&#xA;&lt;li&gt;If a separate tag could be useful, one option would be to create a new &lt;a href=&quot;https://mathoverflow.net/questions/tagged/ordinary-differential-equations&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;ordinary-differential-equations&amp;#39;&quot; rel=&quot;tag&quot;&gt;ordinary-differential-equations&lt;/a&gt; tag. (The limit of length of tag names is now 35 characters, it used to be only 25. Perhaps &lt;a href=&quot;https://mathoverflow.net/questions/tagged/ode&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;ode&amp;#39;&quot; rel=&quot;tag&quot;&gt;ode&lt;/a&gt; and/or &lt;a href=&quot;https://mathoverflow.net/questions/tagged/odes&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;odes&amp;#39;&quot; rel=&quot;tag&quot;&gt;odes&lt;/a&gt; sound like reasonable candidates for synonyms. And if the tag-name seems too long, the shorter version can be chosen as the master tag.)&lt;/li&gt;&#xA;&lt;li&gt;Or the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/differential-equations&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;differential-equations&amp;#39;&quot; rel=&quot;tag&quot;&gt;differential-equations&lt;/a&gt; could be used for this purpose. (I.e., PDEs would be excluded from the tag.) This would mean changing the tag-info and also retagging some older questions. However, I still think that it is better when already the tag name clearly shows what the tag is intended for and askers are able to use the tag correctly even if they do not read the tag-excerpt.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;And since I have already made a post about ODE-related tags, it can probably be decided at the same time whether the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/analysis-and-odes&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;analysis-and-odes&amp;#39;&quot; rel=&quot;tag&quot;&gt;analysis-and-odes&lt;/a&gt; can be removed or whether it makes sense to keep it around. (In the latter case, the intended use of this tag should be clarified.)&lt;/p&gt;&#xA;&#xA;&lt;hr&gt; &#xA;&#xA;&lt;p&gt;Here is what the tag-info for the tags mentioned above says at the moment.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The &lt;a href=&quot;https://mathoverflow.net/revisions/134885/2&quot;&gt;current revision&lt;/a&gt; of the &lt;a href=&quot;https://mathoverflow.net/tags/ca.classical-analysis-and-odes/info&quot;&gt;tag-excerpt for ca.classical-analysis-and-odes&lt;/a&gt;:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Special functions, orthogonal polynomials, harmonic analysis, ordinary differential equations (ODE's), differential relations, calculus of variations, approximations, expansions, asymptotics. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Several of the areas listed there have a separate tag: &lt;a href=&quot;https://mathoverflow.net/questions/tagged/special-functions&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;special-functions&amp;#39;&quot; rel=&quot;tag&quot;&gt;special-functions&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/tagged/orthogonal-polynomials&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;orthogonal-polynomials&amp;#39;&quot; rel=&quot;tag&quot;&gt;orthogonal-polynomials&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/tagged/harmonic-analysis&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;harmonic-analysis&amp;#39;&quot; rel=&quot;tag&quot;&gt;harmonic-analysis&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/tagged/calculus-of-variations&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;calculus-of-variations&amp;#39;&quot; rel=&quot;tag&quot;&gt;calculus-of-variations&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The &lt;a href=&quot;https://mathoverflow.net/revisions/135373/3&quot;&gt;current revision&lt;/a&gt; of the &lt;a href=&quot;https://mathoverflow.net/tags/differential-equations/info&quot;&gt;tag-excerpt for differential-equations&lt;/a&gt;:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Ordinary or partial differential equations.

While I don't think this would be an issue, it could also be countered in several ways. For example, after the first 7 days, you could be offered to pay 100 more reps to keep the bounty (in the old-bounty tab), and if you ever award the bounty, you would get the 100 reps back (or optionally you could also claim it back by removing the bounty).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you don't support this feature, I would be very interested to know why and discuss it.&lt;/p&gt;&#xA;" OwnerUserId="955" LastActivityDate="2020-09-12T08:53:43.657" Title="Should we have standing bounties?"

Particularly, the function that enables one to automatically see records of &lt;em&gt;removed posts&lt;/em&gt; seems to differ from one stackexchange site to another: on many sites such as MO, you may have to check a box that says &quot;show removed posts&quot; before you can see a record of such that affected your reputation. (Go to your user page, and hit the reputation tab where you should then see a log of reputation changes. Scroll all the way to the bottom of the page where you should see a box that says &quot;show removed posts&quot;, and make sure that box has been ticked.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Posts may be removed for example by deletion of posts (whether by the post author, or the community, or the site moderators), or by deletion or destruction of accounts. For those with sufficient reputation (10k+), a link is provided in case it was a post deletion. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;For the record I'll copy over Martin's helpful comments above: &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&quot;IIRC if you check the checkbox &quot;show removed posts&quot; on &lt;a href=&quot;https://mathoverflow.net/users/current?tab=reputation&quot;&gt;your reputation tab&lt;/a&gt;, you should see there also negative reputation changes with links to the posts that cause them.

(Occasionally I notice the term &quot;downvoting&quot; being used to cover a range of activities, including voting to close and voting to delete, although I'd prefer maintaining these distinctions in terminology, for the sake of clarity.) Igor Rivin was only asking about the downvotes on this meta question -- fair enough, although as YCor and also Gerry Myerson noted, the practice of downvoting at meta tends to be much looser and wider than at main, far wider than for reasons of being &quot;unclear&quot; or &quot;little/no research effort&quot;. For example, it is often used to express a disagreement, or a perception that someone is behaving churlishly, etc. I would guess the fact that downvoting at meta is dissociated from reputation change imparts a sense of its being less weighty or consequential, and so it's more liberally applied. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Even if moot for Igor's immediate concern, YCor also noted that answers on main, even if not bad, might be downvoted in order to dissuade others from answering questions perceived as low-quality. If it matters, I (and apparently YCor) expect that's what happened in the case of the question &lt;a href=&quot;https://mathoverflow.net/questions/304542/oriented-angles-of-two-vectors-in-the-3-dimension-euclidean-space/&quot;&gt;https://mathoverflow.net/questions/304542/oriented-angles-of-two-vectors-in-the-3-dimension-euclidean-space/&lt;/a&gt; at main that was deleted. &lt;/p&gt;&#xA;" OwnerUserId="2926" LastActivityDate="2018-07-21T15:29:22.033" CommentCount="1" ContentLicense="CC BY-SA 4.0" />

Check the website for details, but I believe it is from Tobim (GIG) and San Tomas airports from 7a.m. to midnight for the next two days.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is raining now. Dress accordingly.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Check for updates to the venues.  Unconfirmed info suggests Pavilion 3 will not host the plenary and other lectures as planned earlier.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Oh, and use Credit Cards. The tariff for buying BReals at the airport with USD got me less than 2.5 BReals per dollar, as opposed to over 3.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The rapid bus system (BRT) takes some getting used to, but it is an affordable option. Ask for help if you have trouble finding and using the system maps as I did.  Bus 51 stops at RioCentro and Olof Palme (or what ever the next station name is), with the latter a little closer to the Registration Pavilion and my choice when it rains.  Bus 51 also stops at a couple of transfer points, and I use one of them to head West on a different bus towards downtown, Copacabana, and the hostel I'm at.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Hopefully Wi-Fi will improve.

So let me add some details of the procedure that my co-authors and I followed in that case as an example. Hopefully, it might be helpful. (You can find some other similar stories of joint research papers stemmed from MathOverflow on &lt;a href=&quot;https://meta.mathoverflow.net/questions/617/best-of-mathoverflow-or-papers-inspired-by-mathoverflow&quot;&gt;this Meta Post&lt;/a&gt;).&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;My original question received two really nice partial answers. The answers were using techniques that (up to appropriate modifications) could be applied to some other cases and could potentially provide a full characterization of the subject of the original post.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;As I had no contact information (email/website address) attached to my MathOverflow profile at the time, one of the answerers (who eventually became the corresponding author of the joint paper) left a comment in my post asking me to email him. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I reached out to that colleague and he brought up the idea of writing a joint paper with him and the other answerer of the post which I cheerfully accepted. He also provided a primary draft of the paper (containing a brief introduction, the answers and some additional results of him) which we circulated amongst us until a nearly final version was prepared. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;In the paper, the corresponding MathOverflow question is properly cited and it is also mentioned that the original asker of that question is one of the authors. Later, a link to the paper was added to the MathOverflow post as well.         &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;As a final remark, I believe that the &lt;strong&gt;proper citing&lt;/strong&gt; (i.e. The link to the post + The contributor's real name) of any idea that you see on MathOverflow and use in your work is &lt;strong&gt;ethically essential&lt;/strong&gt; no matter if it is substantial or merely a source of inspiration. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is also highly recommended to reach out to the askers/answerers in order to inform them that you are going to use their contribution to MathOverflow in your work as well as asking about their real name if they are posting under the pseudonym here on this site. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It also might be considered inappropriate if you don't offer a co-authorship to them in your ongoing project. As part of the academic etiquette, it is always good to give enough credit to your colleagues. You may leave it to them to decide to collaborate on the paper or not. Note that most of the good researchers actually make the right decision in such cases depending on the degree of essentiality of their contribution to your project.   &lt;/p&gt;&#xA;" OwnerUserId="82843" OwnerDisplayName="Morteza Azad" LastEditorUserId="82843" LastEditDate="2018-07-29T17:57:29.753" LastActivityDate="2018-07-29T17:57:29.753" CommentCount="4" ContentLicense="CC BY-SA 4.0" />

However I would suggest a different approach to suggesting coauthorship (3).  There is (in my view) a risk similar to resume padding when (3) is practiced too much.  In order for MathOverflow to assume a proper place in the assessment of an individual's influence on the literature,  I think it is important to keep a certain distinction between the idea of authoring journal papers (or even ArXived postings) and the idea of authored MathOverflow posts.  The journaled papers suggest an idea (whether true or not) of thorough and ongoing scholarship, while MathOverflow postings are often quick (and sometimes thorough, but often not) responses to solve a specific issue.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Some of us find it easier to do this quick work, and accept credit accordingly.  This is not to say coauthorship shouldn't be offered nor that it should not result from such a collaboration.  It is to say that the degree of the contribution should be weighted accordingly.  More specifically, if the coauthor is willing to help with the writing and additional research of the resulting article, then it makes sense and preserves (to me) the status and meaning implied by coauthorship of a refereed article.  I see the danger of this meaning being altered in a bad way or diluted if (as I read the other answers) it is used as an automatic option, and the person who made the answer is considered as having done much of the research and scholarship, when in fact they haven't.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In short, consider and consult before doing (3), and do it with care and mindfulness of the profession.

(We can leave comments and chat for discussion of this specific edit. But certainly the reason that I was the editor in question was a contributing factor why I decided to post an answer. So I briefly touch also this specific edit in this answer - but that is not the main point of the answer.)&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think that allowing only the OP to edit closed post is not ideal. (On the other hand, in the first days after putting on hold it is definitely preferable if edits comes from the OP at least for salvageable questions, since the first edit - if done within five days - &lt;a href=&quot;https://meta.stackexchange.com/questions/196074/lots-of-questions-in-the-reopen-queue/196078#196078&quot;&gt;pushes the question into the reopen review queue&lt;/a&gt;. But that's a separate topic.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;There might be also some other arguments against the suggestion &quot;only the OP can edit a closed question&quot;, but in fact you pointed out one important one already in your question - namely the tags. If only the OP would be allowed to edit closed question, it might be impossible to remove tags that exists on such questions. To list some recent examples, we might &lt;a href=&quot;https://mathoverflow.net/revisions/306134/4&quot;&gt;still have the misspelled tag&lt;/a&gt; &lt;a href=&quot;https://mathoverflow.net/questions/tagged/probabilty&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;probabilty&amp;#39;&quot; rel=&quot;tag&quot;&gt;probabilty&lt;/a&gt;. Or even if the community agreed that &lt;a href=&quot;https://meta.mathoverflow.net/questions/3788/adding-n-cat-lab-tag&quot;&gt;specific tag for ncatlab&lt;/a&gt; is not suitable, a single user would be able to keep the tag alive simply by refusing to remove it from a single closed question. More importantly, closed questions often come from inexperienced users who are not familiar with tagging systems. And in case of older questions it might be possible that the OP no longer visits the site, so we cannot really expect edit to come from the OP. (Of course, the tag can be removed also when a question is deleted, but it seems that MO users do not vote to delete questions very often.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You have also specifically mentioned old questions. It is true that old questions should not be bumped &lt;em&gt;often&lt;/em&gt;, but with moderation it is acceptable: &lt;a href=&quot;https://meta.mathoverflow.net/q/599&quot;&gt;Do we have an unofficial quota on how many old questions one should bump for minor edits in a single day?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;You have also asked this:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;I am not sure if that adds anything to the question. ... I am not able to see the point of editing a 6 years old question. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I think having questions correctly tagged is useful. It helps when searching and also when choosing the questions in the related questions list in the sidebar. In this specific case the question is closed but it seems unlikely to me that it is going to be deleted. So if it stays, it is probably better for the site that it is &lt;em&gt;correctly tagged&lt;/em&gt; even if it is closed. (But I definitely admit that this is more important for questions that are not closed. And it is much better to make such edits when the question is new or if it has already been bumped for some other reason. Probably I would not have made this specific edit if it wasn't a post with a &lt;a href=&quot;https://meta.mathoverflow.net/questions/3261/what-is-the-correct-way-to-handle-questions-with-deprecated-tags&quot;&gt;deprecated tag&lt;/a&gt;.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Some benefits of bumping this question:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The question gets to the front page and users who see it might reconsider whether it is worth keeping (if not, they might vote to delete it) and also reconsider whether it is worth reopening (although in this specific case this is unlikely scenario).&lt;/li&gt;&#xA;&lt;li&gt;Whoever is curious why the question was bumped and &lt;a href=&quot;https://mathoverflow.net/posts/107989/revisions&quot;&gt;looks at the edit summary&lt;/a&gt; might be reminded that there are deprecated tags. And perhaps the reminder helps that the user helps with the removal of such tags when they see them.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;And a possible downside is only that an old question will be for a short period on the frontpage - which is not that bad. (Considering that I have over 100 helpful spam flags - which means that I contributed to remove quite a few unsuitable posts from frontpage - I definitely feel less guilty if my action leads to some post appearing on the frontpage, even if the post is less than optimal. And I am quite careful not to bump more than one old question per day - which is way below the suggested quota of &lt;a href=&quot;https://meta.mathoverflow.net/questions/599/do-we-have-an-unofficial-quota-on-how-many-old-questions-one-should-bump-for-min&quot;&gt;three questions per day&lt;/a&gt;.)&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2018-07-31T15:06:52.243" LastActivityDate="2018-07-31T15:06:52.243" CommentCount="5" ContentLicense="CC BY-SA 4.0" />

MathOverflow is for the former, and not so much for the latter.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I am not familiar with the mathematics involved in your questions, so I do not know how to help you technically.  The pattern I see (as well as comments by Todd Trimble and others) suggests that you are looking for high-level tutoring.  This is primarily through the timing of the questions (15 in as many days is a bit fast), but also by the appearance of the comments and also the way you use them.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Whether you intend it or not (and whether you are actually doing it or not), it appears to me as if you are reading through a text, encountering a difficulty, spending little or no time thinking on it, asking about it on MathOverflow, and then trying to engage in discussion about the responses you get.  This is the sort of behaviour one might expect between a student and a paid tutor.  This is not quite the service provided by this forum.  The answers are meant to be helpful, but not do much work for you so much as to show you how you can do the work.  (This does not hold for many question-answer examples on MathOverflow, but it is the goal to keep in mind.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In the above, I am inferring a lot from the behaviour I see surrounding your posts.  Maybe you are working hard, busting your head, and asking for help.  I am just not seeing it.  Also, the moderators do not suspend certain account actions lightly; I'm sure there is a good reason.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I am not a moderator, and I really don't know why your account has been modified this way.  My guess is that your behaviour resembles something like the above.  If so, I suggest not asking questions for a while.  You can also write to the moderators by email at moderators@mathoverflow.net and ask what you could do differently. (Especially not raising new technical questions in comments to a post on an existing question; that is an etiquette breach which is important but minor compared to other aspects of this situation.).

I also tend to ask many questions there. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Based on my personal experience, MathOverflow community is mostly concerned about the &lt;strong&gt;quality&lt;/strong&gt; of users' contribution (i.e. research level mathematics) rather than its &lt;strong&gt;quantity&lt;/strong&gt; (i.e. the number of one's posts) or &lt;strong&gt;type&lt;/strong&gt; (i.e. the question, answer, or comment). That is why almost everywhere on this site you see guidelines and comments encouraging people to post as high-quality stuff as possible rather than rules dissuading them from asking many genuine nice questions. Note that:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;Nice questions are in fact the main source of generating high-quality material on this site as there will be no informative answer if there is no one to bring up a related interesting topic in his/her question. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Many high reputation answerers strongly encourage those active community members who provide nice questions, particularly because it allows them to share their knowledge more easily. This happened to me on several occasions when some users of high standing gave me public or private compliments concerning some of my posts.   &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If you are in doubt whether the other users are satisfied with your contribution style, you may pay more attention to the feedback from the community. I personally check my &lt;a href=&quot;https://mathoverflow.net/tags/set-theory/topusers&quot;&gt;vote/post ratio&lt;/a&gt; as an (not completely accurate) indicator of my contribution quality. As far as it is higher than 10 vote/post per month (i.e. average nice question/answer), I assume that the community is more or less satisfied with my contribution. If it drops beneath the mentioned self-imposed threshold, I consider slowing down my asking rate, spending more time on searching around the topic and even consulting some colleagues about the content of the question before posting it, in order to improve the quality of my posts.  &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;As the conclusion, I think there is absolutely nothing wrong with asking a lot of questions without answering any if your questions are high quality enough for this site and if you are able to be always nice and respectful towards other colleagues who may express some critical views towards some of your posts. Good luck with your contribution to MathOverflow! :-)  &lt;/p&gt;&#xA;" OwnerUserId="82843" LastEditorUserId="82843" LastEditDate="2018-08-13T17:51:23.863" LastActivityDate="2018-08-13T17:51:23.863" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

(But it will be certainly nice if some more experienced users share their view.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I consider improving some posts on MO as a useful form of procrastination. So I hope I will procrastinate less in the future and, as a consequence, my edits will annoy less users around here.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;More often than not, when I edit a post MO I tend to leave a brief edit summary. I take it that in these cases the edit summaries were not clear enough to see why I considered the edits useful. (And I hope that at least in some cases, if I hadn't edited those posts, somebody else would.) I will also add that quite often I visit &lt;a href=&quot;https://chat.stackexchange.com/rooms/info/10243/mo-editors-lounge&quot;&gt;MO editors' lounge&lt;/a&gt;, so if there are some issues with my edits, you can also contact me there. (This room was created for discussions related to editing and tagging, it was announced &lt;a href=&quot;https://meta.mathoverflow.net/questions/355/specialized-chat-rooms/662#662&quot;&gt;here by quid&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Let me respond here to some questions asked above and also write a few lines about my views on editing questions on MO (or Stack Exchange sites in general).&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;In my opinion, it is better to edit questions while they are new or if they were recently active (i.e., they have already been bumped for some other reason) than bumping old questions - the latter should not be done too often. (Meaning of &quot;too often&quot; probably depends on the site's culture, on the amount of traffic the site gets, and many other factors.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You have linked to an older post here on meta which contains a recommendation not to edit more than three &lt;em&gt;old questions&lt;/em&gt; per day.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Is it compatible with &lt;a href=&quot;https://meta.mathoverflow.net/q/599&quot;&gt;Do we have an unofficial quota on how many old questions one should bump for minor edits in a single day?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I am aware of the linked post and I try to limit my edits even more than that (typically not more than one edit to an old &lt;em&gt;unbumped&lt;/em&gt; post per day).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The linked examples are mostly questions which were posted recently or were already active for another reason. It is better if a question is edited in such situations than if somebody notices only much later some reason why a post should be edited and bumps it again in several months or in a year or two.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(The first example in the question was an edit to an old question, but it was a post which was recently bumped &lt;a href=&quot;https://mathoverflow.net/questions/21201/book-about-fluid-dynamics/308488#308488&quot;&gt;by adding a new answer&lt;/a&gt;. Probably I should have indicated in the edit summary that this post has been bumped so that this fact would be better visible. Here is another example of my edit where I &lt;a href=&quot;https://mathoverflow.net/posts/126420/revisions&quot;&gt;explicitly mentioned in the edit summary&lt;/a&gt; that the question had been bumped - in that case it was by &lt;a href=&quot;https://mathoverflow.net/questions/126420/functions-of-one-complex-variable-geometric-theory/308321#308321&quot;&gt;adding a new answer&lt;/a&gt;, too.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You can easily check that I am definitely not the only person &lt;a href=&quot;https://mathoverflow.net/search?tab=active&amp;amp;q=created%3a2009-01-01..2018-01-01&quot;&gt;bumping older posts&lt;/a&gt;. And there are certainly &lt;a href=&quot;https://mathoverflow.net/users?tab=Editors&amp;amp;filter=all&quot;&gt;many active editors&lt;/a&gt; on MathOverflow. (Although the activity of editors may vary with time.)&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;For me it is little annoying to see the same name on most of the questions/answers as &quot;edited ** ago&quot;.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Probably the best solution to this that I can think of is that more MO users help with editing and retagging. (I see that &lt;a href=&quot;https://mathoverflow.net/users/118688/praphulla-koushik?tab=activity&amp;amp;sort=suggestions&quot;&gt;you have already started&lt;/a&gt; and I certainly appreciate your efforts.) Although claiming that you see the same name on most of the posts seems to me like diminishing work done by other editors.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;There are various types of edits which can be considered useful.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Personally I would consider even grammar corrections and correcting typos beneficial. The sentence &quot;there are various reasons why I edit posts&quot; is easier to read than &quot;there are various reason why i edit pots&quot;. Although such a minor edit would not be a sufficient reason to edit an &lt;em&gt;old&lt;/em&gt; post.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Similarly, I think that improving &lt;a href=&quot;https://meta.mathoverflow.net/tags/mathjax/info&quot;&gt;MathJax&lt;/a&gt;/&lt;a href=&quot;https://meta.mathoverflow.net/tags/markdown/info&quot;&gt;MarkDown&lt;/a&gt; in the posts can be useful. (Especially for users that are not really experienced with them.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;There was a separate discussion about adding links to the material referenced in MO posts, and judging by the response to that question, such edits are also considered useful: &lt;a href=&quot;https://meta.mathoverflow.net/q/3030&quot;&gt;Is it worth editing old posts to add links for references?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;I consider also retagging questions which do not have correct tags rather useful. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Correct tags are useful for several reasons. They help when searching the site. (I think that at least some of the questions and answers might be useful also to users other than the asker.) And they help also the poster of the question - since people following the added tags are more likely to notice the question.&#xA;I don't think I will summarize it better than what is already written here: &lt;a href=&quot;https://meta.mathoverflow.net/q/1075#1093&quot;&gt;What are the advantages of proper tagging?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One of the specific features of the tagging system on this site, is that every question is supposed to have one of the top-level tags, see also: &lt;a href=&quot;https://meta.mathoverflow.net/q/1075#1076&quot;&gt;What are top level tags, and why should I try to use them?&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/q/1457&quot;&gt;Why are MO tags formatted as they are?&lt;/a&gt;. (Again, one of the edits mentioned in the question is of this type, I have explicitly mentioned this &lt;a href=&quot;https://mathoverflow.net/posts/308387/revisions&quot;&gt;in the edit summary&lt;/a&gt;.) Although at least in some cases finding top-level tags might be problematic (see, for example: &lt;a href=&quot;https://meta.mathoverflow.net/q/3625&quot;&gt;On the top-level tag ra.rings-and-algebras&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/q/3447&quot;&gt;Which “non-arxiv” tags are de facto top-level tags?&lt;/a&gt;). Regarding top-level tags, I will quote &lt;a href=&quot;https://chat.stackexchange.com/transcript/message/40567644#40567644&quot;&gt;one of the MathOverflow moderators&lt;/a&gt;:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Yes, the tag management on MO is very different than on Mathematics. There are several reasons for that. For example, the systematic use of broad area tags borrowed from the arxiv on day one brought a lot of stability to the general tagging system here.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;The top-level tags have been also mentioned to you recently &lt;a href=&quot;https://chat.stackexchange.com/transcript/9417?m=46222289#46222289&quot;&gt;in the Homotopy Theory chatroom&lt;/a&gt;:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;You don't need to put only one tag, you can put up to five. In general it is recommended to put a very general tag (usually an &quot;arxiv&quot; tag) to indicate broadly which sector of math your question is in, and then more specific tags.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;With respect to tags, MathOverflow has one more unresolved issue, which is &lt;a href=&quot;https://meta.mathoverflow.net/questions/3261/what-is-the-correct-way-to-handle-questions-with-deprecated-tags&quot;&gt;deprecated tags&lt;/a&gt;. There are several tags which should be eliminated, which cannot be done without some amount of manual editing. It seems that several edits mentioned here were of this type - and also the edit mentioned in this recent post on meta: &lt;a href=&quot;https://meta.mathoverflow.net/q/3832&quot;&gt;Restriction on editing closed questions&lt;/a&gt;. When I do such edits, I usually mention this in the edit summary (as I did in those cases - &lt;a href=&quot;https://mathoverflow.net/posts/107989/revisions&quot;&gt;107989&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/242173/revisions&quot;&gt;242173&lt;/a&gt;). Considering the fact that the number of the questions with deprecated tags decreases at the rate &lt;a href=&quot;https://chat.stackexchange.com/rooms/10243/conversation/how-fast-are-deprecated-tags-getting-removed&quot;&gt;about 10 questions per month&lt;/a&gt;, it does not seem very likely that they are going to be removed anytime soon. But perhaps at least something could be done to prevent this number from increasing so that these tags cannot be added to new questions &lt;a href=&quot;https://meta.mathoverflow.net/questions/3718/the-existing-deprecated-tags-should-be-blacklisted&quot;&gt;as I suggested elsewhere&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Personally, I consider use of tags especially important on meta - since many issues mentioned there tend to come up repeatedly and tags help a lot when searching and also when &lt;a href=&quot;https://meta.stackexchange.com/questions/27566/would-it-be-feasible-to-tie-the-tags-of-a-new-question-to-the-related-questions-l&quot;&gt;populating the related question lists&lt;/a&gt;.&#xA;To include an example, I will use something from another site that I am more familiar with. One of the issues that repeatedly come up on meta is that comments containing long MathJax expressions tend to be jumbled sometimes. On Mathematics Meta, I can simply use the search using &lt;a href=&quot;https://math.meta.stackexchange.com/questions/tagged/comment+mathjax&quot;&gt;combination of the two relevant tags&lt;/a&gt;, and I can easily find several past discussions about this issue. (And if needed, I can restrict this search further, for example by adding some keywords or if I remember a user who posted an answer to such question, I can restrict the search to their posts. For comparison, on this meta I was able to find two posts about this issue, both of them are now tagged &lt;a href=&quot;https://meta.mathoverflow.net/questions/tagged/mathjax+comments&quot;&gt;mathjax+comments&lt;/a&gt;: &lt;a href=&quot;https://meta.mathoverflow.net/q/1148&quot;&gt;The math! It's overflowing!&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/q/2390&quot;&gt;Long MathJax in comment breaks linewrapping throughout the comment thread&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Even though some of them are mentioned above, let me go through examples mentioned in the question one by one.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&quot;&lt;a href=&quot;https://mathoverflow.net/q/21201&quot;&gt;Book about fluid dynamics&lt;/a&gt; asked Apr 13 '10 edited 1 hour ago&quot; - since this question has been bumped anyway by &lt;a href=&quot;https://mathoverflow.net/posts/21201/revisions&quot;&gt;adding a new answer&lt;/a&gt;, it seemed rather natural to look whether there are other things that can be improved by editing the question or some of the answers. The tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/books&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;books&amp;#39;&quot; rel=&quot;tag&quot;&gt;books&lt;/a&gt; was used there incorrectly, at least if we follow the guidance given in the &lt;a href=&quot;https://mathoverflow.net/revisions/135707/2&quot;&gt;current revision&lt;/a&gt; of &lt;a href=&quot;https://mathoverflow.net/tags/books/info&quot;&gt;the tag-info&lt;/a&gt;. I have included link to the tag-info &lt;a href=&quot;https://mathoverflow.net/posts/21201/revisions&quot;&gt;in the edit summary&lt;/a&gt;. (Let me also say that I have asked a few times in chat &lt;a href=&quot;https://chat.stackexchange.com/search?q=%22tagged%2Fbooks%22&amp;amp;room=10243&quot;&gt;about the (books) tag&lt;/a&gt;, since it seems that the tag is often used differently from this guidance.) I guess that when somebody searches for a question like this, they might typically use tags &lt;a href=&quot;https://mathoverflow.net/questions/tagged/fluid-dynamics+textbook-recommendation&quot;&gt;fluid-dynamics+textbook-recommendation&lt;/a&gt; or &lt;a href=&quot;https://mathoverflow.net/questions/tagged/fluid-dynamics+reference-request&quot;&gt;fluid-dynamics+reference-request&lt;/a&gt;, so the change of tags can be useful for searching.&lt;/li&gt;&#xA;&lt;li&gt;&quot;&lt;a href=&quot;https://mathoverflow.net/q/308464&quot;&gt;Are there examples of conjectures supported by heuristic arguments that have been finally disproved?&lt;/a&gt; asked 21 hours ago edited 2 hours ago&quot;. Here I have &lt;a href=&quot;https://mathoverflow.net/posts/308464/revisions&quot;&gt;added (conjectures) tag&lt;/a&gt;, to me it seems as a question that one would hope to find when searching using this tag. It was a recent question and it was really active (it even got in HNQ). I would not consider the fact that I bumped this question much of an issue - some 10 minutes after my edit it was bumped again &lt;a href=&quot;https://mathoverflow.net/posts/308525/revisions&quot;&gt;by an edit to an answer&lt;/a&gt;. Moreover, the question is a &lt;a href=&quot;https://meta.mathoverflow.net/tags/community-wiki/info&quot;&gt;community wiki&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;&quot;&lt;a href=&quot;https://mathoverflow.net/q/242173&quot;&gt;Division ring on a field&lt;/a&gt; asked Jun 14 '16 edited 2 hours ago&quot; - among the questions listed above, this is the only old question which I bumped. In this case it was to remove the deprecated &lt;a href=&quot;https://mathoverflow.net/questions/tagged/abstract-algebra&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;abstract-algebra&amp;#39;&quot; rel=&quot;tag&quot;&gt;abstract-algebra&lt;/a&gt; tag, which I have also &lt;a href=&quot;https://mathoverflow.net/posts/242173/revisions&quot;&gt;mentioned in the edit summary&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;&quot;&lt;a href=&quot;https://mathoverflow.net/q/308506&quot;&gt;Halin Graphs with Highest Number of Hamilton Cycles&lt;/a&gt; asked 8 hours ago edited 5 hours ago.&quot; As mentioned before, it is useful when question has also some of the bigger tags, not only very specialized tags - which is why I added the &lt;a href=&quot;https://mathoverflow.net/questions/tagged/graph-theory&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;graph-theory&amp;#39;&quot; rel=&quot;tag&quot;&gt;graph-theory&lt;/a&gt; tag. You may notice that after my edit, the question was &lt;a href=&quot;https://mathoverflow.net/posts/308506/revisions&quot;&gt;further edited by other user and then by OP&lt;/a&gt;. (Maybe I should have also added a link to the paper mentioned there to make this edit more complete. On the other hand, the post has a link to a Wikipedia article and this paper is there among references with a link.)&lt;/li&gt;&#xA;&lt;li&gt;&quot;&lt;a href=&quot;https://mathoverflow.net/q/308387&quot;&gt;Applying a piecewise linear function to vertices of a polytope while remaining in facet representation&lt;/a&gt; asked yesterday edited 6 hours ago&quot; - in this case I was adding a top-level tag, as I &lt;a href=&quot;https://mathoverflow.net/posts/308387/revisions&quot;&gt;explicitly mentioned in the edit summary&lt;/a&gt;. Again, this was quite a recent post and since it was bumped a few minutes before my edit, I do not think my edit caused any harm.&lt;/li&gt;&#xA;&lt;li&gt;&quot;&lt;a href=&quot;https://mathoverflow.net/q/308239&quot;&gt;Is every metric continuum almost path-connected?&lt;/a&gt; asked Aug 14 at 6:49 edited 18 hours ago&quot; - in this case the text of the question indicated that the OP wanted to link to another question and they linked to an answer, most likely by mistake. So I have edited link and again &lt;a href=&quot;https://mathoverflow.net/posts/308239/revisions&quot;&gt;mentioned this in the edit summary&lt;/a&gt;. The subsequent edit by the OP suggests that this is probably what they wanted. &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;The question also includes the number of edits per day. In case you're interested, here is a &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;data explorer&lt;/a&gt; query where you can check number:&#xA;&lt;a href=&quot;http://data.stackexchange.com/mathoverflow/revision/888350/1103304/edits-by-a-specific-user-per-day-without-counting-tags-title-body-separatedly?userid=8250&quot; rel=&quot;nofollow noreferrer&quot;&gt;Edits by a specific user per day&lt;/a&gt;. (And you can even experiment and compare the numbers for other users.) Highest numbers of edits per day by a single user are above 20, record being 67 edits: &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/revision/888356/1103309/most-edits-per-day-without-counting-title-body-tag-edits-separately&quot; rel=&quot;nofollow noreferrer&quot;&gt;Most edits per day&lt;/a&gt;. (Here it a &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/revision/888358/1103311/most-edits-per-day-including-displayname&quot; rel=&quot;nofollow noreferrer&quot;&gt;version of the same query&lt;/a&gt; with displayname - since for deleted users the userid is not stored.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The number of edits can be bigger than the number of actual questions that have been bumped. For example, they include edit on tag-wikis, multiple edits on the same posts. They also include edits both to a question and some of the answer - which only bump one question. (As I have already mentioned, if a question is already bumped and there is something else worth editing, it is suitable to do so soon after the bump.)  So even if this is a problem, the numbers might make it look slightly exaggerated.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For example, if I look at &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/revision/888350/1103304/edits-by-a-specific-user-per-day-without-counting-tags-title-body-separatedly?userid=8250&quot; rel=&quot;nofollow noreferrer&quot;&gt;my counts from SEDE&lt;/a&gt;, the 8 edits on August 7 include five edits to a question and also to the answers there (&lt;a href=&quot;https://mathoverflow.net/posts/40178/revisions&quot;&gt;40178&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/40227/revisions&quot;&gt;40227&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/40280/revisions&quot;&gt;40280&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/40183/revisions&quot;&gt;40183&lt;/a&gt;), so even though this counted as five edits, only one question was bumped. Similarly on August 10 those were five edits to a question and answers on that question (&lt;a href=&quot;https://mathoverflow.net/posts/52708/revisions&quot;&gt;52708&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/52756/revisions&quot;&gt;52756&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/52786/revisions&quot;&gt;52786&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/52789/revisions&quot;&gt;52789&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/68858/revisions&quot;&gt;68858&lt;/a&gt;). The 8 edits on August 16 include five edits to tag-wikis&#xA;(&lt;a href=&quot;https://mathoverflow.net/posts/237087/revisions&quot;&gt;arithmetic-topology&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/236930/revisions&quot;&gt;birational-geometry&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/236895/revisions&quot;&gt;higher-category-theory&lt;/a&gt;, continuum theory &lt;a href=&quot;https://mathoverflow.net/posts/308280/revisions&quot;&gt;tag-excerpt&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/posts/308279/revisions&quot;&gt;tag-wiki&lt;/a&gt;), so no post was bumped by these five edits. (Three of them are related to the problem mentioned in this thread: &lt;a href=&quot;https://meta.mathoverflow.net/q/2849&quot;&gt;Recent suggested tag wiki edits&lt;/a&gt;. The other two were edits to the tag-info of a recently created tag where the link in the tag-excerpt was not working.) Similarly there are five tag-wiki edits among the 16 edits on August 14.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2018-08-19T09:42:16.573" LastActivityDate="2018-08-19T09:42:16.573" CommentCount="7" ContentLicense="CC BY-SA 4.0" />

But this may be a good time to revisit the discussion of some of the ways MathOverflow has been known to use CW, which differ from how many other StackExchange sites use it, and which are consistent with certain traditions since before we were part of the SE network. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Currently it's only the site moderators who can make &lt;em&gt;questions&lt;/em&gt; CW, or who can undo that action. If a question is CW, then so automatically are the answers. On the other hand, if a question is not CW, a user who has answered can make his/her post CW independently, without affecting other posts within the thread. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Speaking as an active moderator, most times I make a question CW are after it was flagged as a possible candidate for such, although sometimes I'll do it without prior prompting if it seems to me well within the wheelhouse of questions we've traditionally made CW. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Questions that are typically or at least often made CW include&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;Career advice questions, &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Questions regarding style (e.g., in writing papers), &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Big-list questions, especially if they quantify over all mathematical fields. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;A justification is that, especially in such cases, there may be strong differences of opinion, each with weight and argumentation behind it, regarding which answers are better than others. [For example, whether to punctuate at the end of a display line, or whether in a paper one should refer to an earlier Proposition using a capital P.] Here it seems sensible to put it to the community and sort it out with large numbers of votes, and the community generally feels more invited to vote up or down when reputation points are not at stake. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(By the way, when I asked, site moderators felt that Mike's question came under the umbrella of the third bulleted point.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;An &lt;em&gt;answer&lt;/em&gt; is often made CW in order to avoid an &lt;em&gt;unseemly&lt;/em&gt; appearance of existing for the sake of gaining reputation. For example, a question may have answered in comments, and someone culls the comments together to form an answer, but makes the answer CW in order not to take credit (in the form of reputation points) for answers by others. As a community service. This can also be done in cases where different people answered different parts of a multi-part series of questions within a single post, whereupon arises the nettlesome difficulty of which answer to officially accept. The difficulty can be neatly finessed by assembling all the partial answers into a single master answer and then marking that one CW, courteously assigning all credit where credit is due. Marking that as the official answer then seems a satisfactory solution. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Another example: if someone asks a question but already knows an answer, and posts the answer concurrently with the question, then she might make the answer CW, again to signal that it's not meant to step in front of other answers (after all, often the early bird gets the worm where points are concerned), but more along the lines of selflessly adding to the public commons. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;None of this is actually written down as MathOverflow official policy. That in itself might make some people uncomfortable; my hope is that this answer might help lessen the discomfort a little. My understanding as expressed above is based mostly on informal traditions and things that have frequently been said over the years, much of it in comments at Main, or in flags. So some of it is a bit hard for me to quantify. One early discussion of such matters may be found at 'tea': &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/6/when-should-questions-be-community-wiki/&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://mathoverflow.tqft.net/discussion/6/when-should-questions-be-community-wiki/&lt;/a&gt;, and here's another: &lt;a href=&quot;http://mathoverflow.tqft.net/discussion/247/question-mysteriously-becoming-community-wiki/?Focus=4242&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://mathoverflow.tqft.net/discussion/247/question-mysteriously-becoming-community-wiki/?Focus=4242&lt;/a&gt;  More recently there was this: &lt;a href=&quot;https://meta.mathoverflow.net/questions/3573/why-was-this-question-made-community-wiki&quot;&gt;Why was this question made community wiki?&lt;/a&gt;&lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="-1" LastEditDate="2018-11-02T16:52:05.143" LastActivityDate="2018-08-18T21:44:42.783" CommentCount="12" ContentLicense="CC BY-SA 4.0" />

Probably anybody who spent some time around this site has noticed a few mentions about this - mostly on meta (And it goes also the other way round, there are many people with not very good opinion on MathOverflow.) So you have to decide for yourself whether or not you consider contributing to that site a useful thing to do.&#xA;&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Mathematics has much higher traffic than MathOverflow and an average question there is on lower level than most questions here, so it is a bit harder to find interesting questions there. Since you are most likely interested in more advanced staff, it probably would make sense to add a few areas you are interested in to your favorite/watched tags and simply check only &lt;a href=&quot;https://math.stackexchange.com/search?tab=active&amp;amp;q=intags:mine&quot;&gt;questions in those tags&lt;/a&gt;. Or simply bookmark a link to search which returns &lt;a href=&quot;https://math.stackexchange.com/questions/tagged/algebraic-geometry+or+differential-geometry+or+category-theory&quot;&gt;questions in the tags where you are most likely to add answers&lt;/a&gt;.

A small handful of small edits may fly under the radar, or otherwise might be excused, but I'd say you have to be careful/thoughtful. (I think this is consistent with the answer given &lt;a href=&quot;https://meta.mathoverflow.net/a/1111/2926&quot;&gt;here&lt;/a&gt;, mentioned by Martin, to a slightly different question.) Indeed, some users have been known to exhaust the patience of the community with dozens of tiny edits. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I'd like to add a general rule of thumb: whenever you edit, you should make a good faith effort to catch as many blemishes as you can at that pass. Put slightly differently: holding a few blemishes in reserve for a future edit is, one could argue, a form of dishonesty. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think that addresses your first question. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As for the proposal (set off in a gray box): I agree with Asaf in the comments that it's not a good idea, for reasons he mentions. From there the comment thread is largely about how to interpret a lack of response to a question that has been upvoted. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I see three likely explanations: &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;The question is so hard that even experts are stuck. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The question is not that hard, but people who could answer haven't seen it yet. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;People who could answer (if they wanted) have seen it, but for one reason or another they have not been moved to reply. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;If it's the first scenario, patience is required. Hopefully the question is both so interesting and so challenging that it will be upvoted a lot, so that someone will be motivated to answer and claim the prize. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In addition to crafting an interesting well-written question, precise and thoughtful tagging may lessen the chances of the second scenario. You can get a better idea of whether it's gotten good attention by looking at page view numbers, more so than by counting votes in my opinion. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I would guess that oftentimes, we're actually in the third scenario, which is unfortunate. I regret to say that my own reaction to a lot of questions where I have some knowledge is a firm &quot;meh&quot; -- it could be that I think the question is lazy or poorly researched, or arguably/suspectedly below the level of the site, or too tedious, or maybe even too rebarbative (e.g., the OP seems likely to want to argue with me) -- whatever the reason, I may feel that the question is, for me, not worth the bother of putting together an answer. If others feel the same way, than generally speaking, small edits are not going to cut it in this case, and could very easily backfire. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Just as in writing papers, in many cases you can't &lt;em&gt;make&lt;/em&gt; people get interested unless you explain why it's interesting, or why an answer is so important. I apologize if this advice sounds like boilerplate, but in my opinion the advice is not heeded nearly as much as it should be. Giving background can help a lot. Giving evidence of trying hard to find the answer yourself can help a lot. If knowledgeable people see that you've been knocking your head against a wall for an hour or more without success, and tried hard to ask a question with care (even down to small details), then the chances are much better you'll be lent a sympathetic hand. &lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="2926" LastEditDate="2018-09-03T02:13:53.737" LastActivityDate="2018-09-03T02:13:53.737" CommentCount="11" ContentLicense="CC BY-SA 4.0" />

As Gerhard mentioned, there is a separate non-profit run by the moderators which exists mainly to hold onto our option to go independent of the larger StackExchange world if the need ever arose; it also exists to accept funds which could potentially be used against future costs (ironically, the main thing we have actually used money for is to set up the LLC; this was done with a grant from the Sloan Foundation).  Again, I don't think that the MO community would elect someone who didn't appreciate the site's mission and what makes it different, but a moderator election would raise some sticky questions (would we commit to adding the new moderator to the board before the election?) that seem like unnecessary complications.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The opposite side of this is the potential benefits.  I think that this question started with the observation that several of the moderators are not especially active.  This is undoubtedly true, but largely stems from the fact that Todd tends to get to moderation flags before any of the rest of us have a chance to see them.  The number of questions requiring by hand moderator intervention is quite small (and most them don't actually require it); if you look in &lt;a href=&quot;http://data.stackexchange.com/mathoverflow/revision/890114/1105753/recent-mod-actions-on-questions&quot; rel=&quot;nofollow noreferrer&quot;&gt;data explorer&lt;/a&gt;, you'll see Todd took almost all the by-hand actions in the last year, but that the total number (not counting Community) is around 50, so one a week.  Actually, becoming a moderator can interfere with participating in day-to-day moderation, since voting for closure or deletion as a &quot;civilian&quot; is impossible and your vote on its own will close or delete a question. I think arguably the last few years proves that Todd could handle the day-to-day moderation on his own if he needed to (not that we would ask him to).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, the much more important thing moderators do is deal with occasional weird and difficult cases (we occasionally have banned users who very stubbornly try to post under different accounts, vote fraud, etc.) and act as long term stewards of the site.  We do also have the bully pulpit to weigh in on issues facing the site, though that's only really our moral suasion (and electing a new moderator wouldn't do much to give them more authority on this point).  If that or some other aspect of the moderator job needs new blood, I think the current moderation team is quite open to having elections, but I haven't seen a strong argument for it.&lt;/p&gt;&#xA;" OwnerUserId="66" LastActivityDate="2018-09-11T13:53:09.440" CommentCount="5" ContentLicense="CC BY-SA 4.0" />

Wiles deserved and got recognition for the amount of effort he put in and results he got out, even in 1993, but the public (and even most mathematicians) would not understand or appreciate what he did up to that year. If the masses need to understand anything, it is that it takes time to turn claims of a proof into something that properly belongs to the literature.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think Sir Michael Atiyah has some ideas worth hearing.  For reasons personal to me, I do not want to hear them from Sir Michael directly.

That means someone other than Sir Michael finds a way to present the ideas, or parts of them, in a fashion that is more clear, more self contained, and more about the math than the media.

In the name of consistency, I think that would be the right reaction here as well, and that should really be the policy. So any question that asks for responses on whether this is right or wrong, or if there is something there, should be treated in the way it's always been treated: we at MO do not vet papers that purport to solve famous open problems. And in the case of 5-page articles that announce a solution of RH: we don't discuss them at all. The question will be closed. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;My personal opinion is that the situation and the appropriate reaction is made only slightly more complicated by knowing it was Atiyah. There are indeed allusions to sophisticated concepts such as the Todd genus (there is a &quot;Todd function&quot; which is somehow related to the Todd genus). Careful and precise questions about such concepts, at a professional level, are always in principle allowable, and they may mention that some such concept was spotted in Atiyah's article, but these should not turn into cover for discussing the current topic. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;We don't think it's possible to spell out policy in advance that will cover every such circumstance; some matters have to be treated on a case-by-case basis, with input from the community.

Please: just be prudent, and avoid drama. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;We have no doubt there will be those who cry &quot;censorship!&quot;, &quot;suppression of free thought!&quot;, etc. Or, less dramatically: how do you know there's nothing there?  Well, none of us know for a fact, and obviously Atiyah's track record from when he was in his prime will give some people pause: for many years he has led mathematicians across difficult country. There may well be a tragic aspect to what is unfolding before us. Let's please preserve some dignity for the man. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Don't worry: if there is truly mathematical takeaway, it will be picked up by the experts. RH will never be solved in a day: any serious solution will take months or years to be pored over and analysed by thousands at home, in offices, in seminar rooms around the world.

One needs not only an idea to popularize, but an adequately expressed form of it, just to have something to work with.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Since making an idea accessible to many others is a lot of work, we do not ask our members to go beyond the second stage.

Just look at answering questions as a kind of &quot;competition&quot; between answerers. If the same question has several answers, the answerers are competing with each other, and the answer with most upvotes is on top. (Well, usually - it depends on how user chooses to sort the answers, but this seems to be the most frequently used setting.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So if your main objective would be to maximize reputation, it's better for you to have your answer among the higher voted answers near to the top - since it is more visible. But if other answers are good, it is nice of you to upvote them - even if this means that your answer might gets ranked lower and thus less visible. So in this way your behavior is &quot;sportsmanlike&quot; - you help people who &quot;compete&quot; against you, in a sense.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(Whether or not looking at participation on MathOverflow and other Stack Exchange sites as a &quot;competition&quot; is more useful or more harmful is up for debate - probably it has both positive and negative aspects.

In fact I think we are nearer to perfectoid spaces than complex manifolds -- maybe because algebra is closer to the axioms than analysis. But actually we also have Lebesgue measure (it's differentiability we're not too strong at), and today we got modular forms. There is a sort of an indication of where we are.&lt;/p&gt;&#xA;&lt;p&gt;What else should we be doing? What should we work on next?&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Some background.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;The Lean theorem prover is a computer program which can check mathematical proofs which are written in a sufficiently formal mathematical language. You can read my &lt;a href=&quot;https://xenaproject.wordpress.com/2018/09/22/formalising-mathematics-a-mathematicians-personal-viewpoint/&quot; rel=&quot;nofollow noreferrer&quot;&gt;personal thoughts&lt;/a&gt; on why I believe this sort of thing is timely and important for the pure mathematics community. Other formal proof verification software exists (Coq, Isabelle, Mizar...). I am very ignorant when it comes to other theorem provers and feel like I would like to see a comparison of where they all are.&lt;/p&gt;&#xA;&lt;p&gt;Over the last year I have become increasingly interested in Lean's &lt;a href=&quot;https://github.com/leanprover/mathlib&quot; rel=&quot;nofollow noreferrer&quot;&gt;mathematics library&lt;/a&gt;, because it contains a bunch of what I as a number theorist regard as &amp;quot;normal mathematics&amp;quot;. No issues with constructivism, the axiom of choice, quotients by equivalence relations, the law of the excluded middle or anything. My impression that most mathematicians are not particularly knowledgeable about what can actually be done now with computer proof checkers, and perhaps many have no interest. These paragraphs are an attempt to give an update to the community.&lt;/p&gt;&#xA;&lt;p&gt;Let's start by getting one thing straight -- formalising deep mathematical proofs is &lt;em&gt;extremely hard&lt;/em&gt;. For example, it would cost tens of millions of dollars &lt;em&gt;at least&lt;/em&gt;, i.e. many many person-years, to formalize and &lt;em&gt;maintain&lt;/em&gt; (a &lt;a href=&quot;https://en.wikipedia.org/wiki/Curry%E2%80%93Howard_correspondence&quot; rel=&quot;nofollow noreferrer&quot;&gt;proof is a computer program&lt;/a&gt;, and computer programs needs maintaining!) a complete proof of Fermat's Last Theorem in a theorem prover. It would certainly be theoretically possible, but it is not currently clear to me whether any funding bodies are interested in that sort of project.&lt;/p&gt;&#xA;&lt;p&gt;But formalising deep mathematical &lt;em&gt;objects&lt;/em&gt; is really possible nowadays. I &lt;a href=&quot;https://github.com/kbuzzard/lean-stacks-project&quot; rel=&quot;nofollow noreferrer&quot;&gt;formalised the definition of a scheme&lt;/a&gt; earlier this year. But here's the funny thing. 15 months ago I had never heard of the Lean Theorem Prover, and I had never used anything like a theorem prover in my life. Then in July 2017 I watched a live stream (thank you Newton Institute!) of &lt;a href=&quot;https://www.newton.ac.uk/seminar/20170710100011001&quot; rel=&quot;nofollow noreferrer&quot;&gt;Tom Hales' talk in Cambridge&lt;/a&gt;, and in particular I saw his answer to Tobias Nipkow's question 48 minutes in. And here we are now, just over a year later, with me &lt;a href=&quot;https://github.com/kbuzzard/lean-perfectoid-spaces&quot; rel=&quot;nofollow noreferrer&quot;&gt;half way through perfectoid spaces&lt;/a&gt;, integrating Lean into my first year undergraduate teaching, and two of my starting second year Imperial College undergraduate students, &lt;a href=&quot;https://github.com/dorhinj/Sylow&quot; rel=&quot;nofollow noreferrer&quot;&gt;Chris Hughes&lt;/a&gt; and &lt;a href=&quot;https://github.com/kckennylau/local-langlands-abelian&quot; rel=&quot;nofollow noreferrer&quot;&gt;Kenny Lau&lt;/a&gt;, both much better than me at it. The links are to their first year undergraduate projects, one a complete formal proof of Sylow's theorems and the other an almost finished formalization of the local Langlands conjectures for abelian algebraic groups over a p-adic field. It's all open source, we are writing the new Bourbaki in our spare time and I cannot see it stopping. I know many people don't care about Bourbaki, and I know it's not a perfect analogy, but I do care about Bourbaki. I want to know which chapters should get written next, because writing them is something I find really good fun.&lt;/p&gt;&#xA;&lt;p&gt;But why write Bourbaki in a computer language? Well whether you care or not, I think it's going to happen. Because it's there. Whether it happens in Lean or one of the other systems -- time will tell. Tom Hales' &lt;a href=&quot;https://github.com/formalabstracts/formalabstracts&quot; rel=&quot;nofollow noreferrer&quot;&gt;formal abstracts project&lt;/a&gt; plans to formalise the statements of new theorems (in Lean) as they come out -- &lt;a href=&quot;https://jiggerwit.wordpress.com/&quot; rel=&quot;nofollow noreferrer&quot;&gt;look at his blog&lt;/a&gt; to read more about his project. But to formalise the statements of hard theorems you have to formalise the definitions first. Mathematics is &lt;em&gt;built on rigorous definitions&lt;/em&gt;. Computers are now capable of understanding many more mathematical definitions than they have ever been told, and I believe that this is mostly because the mathematical community, myself included, just didn't ever realise or care that it was happening. If you're a mathematician, I challenge you to formalise your best theorem in a theorem prover and send it to Tom Hales! If you need hints about how to do that in Lean, come and ask us at the Lean Zulip chat. And if if it turns out that you can't do it because you are missing some definitions, you can put them down here as answers to this big list question.&lt;/p&gt;&#xA;&lt;p&gt;We are a small but growing community at &lt;a href=&quot;https://leanprover.zulipchat.com/&quot; rel=&quot;nofollow noreferrer&quot;&gt;the Lean prover Zulip chat&lt;/a&gt; and I am asking for direction.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;(And now my suggestions for edits.)&lt;/p&gt;&#xA;&lt;p&gt;Let's leave the Question and the Examples sections as they are, as these seem not to be in question.&lt;/p&gt;&#xA;&lt;p&gt;The first paragraph of the Background section seems very appropriate to me: it's informational, and the author should be allowed to say why this is important to him by linking to his blog post. If the author would like to mention briefly that the software is open source, this might be the best place (&amp;quot;The Lean theorem prover is an open source computer program...&amp;quot;). However, I would modify the last sentence&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;I am very ignorant when it comes to other theorem provers and feel like I would like to see a comparison of where they all are.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;to something more like this:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;I am unfortunately ignorant when it comes to these other theorem provers; if it seems that I am focusing on Lean to the exclusion of the others, it's only because it's Lean that I have experience with.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;(I am removing the bit about &amp;quot;would like to see a comparison&amp;quot; because that should not be construed as part of the question -- presumably answers that go into comparisons would be considered &amp;quot;not an answer&amp;quot;, i.e., not relevant.)&lt;/p&gt;&#xA;&lt;p&gt;I would either remove the second paragraph or replace it with something different. To me it is alluding to some invidious comparisons between Lean and what the author thinks about the other theorem provers out there (as being not well adapted to doing &amp;quot;normal mathematics&amp;quot;, presumably, and allegedly overly occupied with &amp;quot;niche concerns&amp;quot; as Kevin opined in a comment). At most I would constrain it to something like&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;For mathematicians who are worried about being able to understand the formalization, I invite them to take a look at Lean's &lt;a href=&quot;https://github.com/leanprover/mathlib&quot; rel=&quot;nofollow noreferrer&quot;&gt;mathematics library&lt;/a&gt;. My own experience suggests that you do not at all have to be a logician or type theorist to begin using this technology (15 months ago I had never heard of the Lean Theorem Prover, and I had never used anything like a theorem prover in my life). Plus, looking over the library may give the reader a better sense of which gaps need filling in Lean.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;The next few paragraphs, as I read them, are really (or should be) about clarifying the scope of the question. But they should be trimmed down just to get that across, because as they stand they sort of go on and on. Also, I'm being picky here, but tonally &amp;quot;Let's start with getting one thing straight&amp;quot; sounds a bit like the beginning of a rejoinder in an argument with someone. Here's what I might try instead:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Let's start with saying one thing up front: formalising deep mathematical &lt;em&gt;proofs&lt;/em&gt; is &lt;em&gt;extremely hard, time-consuming, and costly&lt;/em&gt;. (I estimate it would take upwards of tens of millions of dollars to implement and maintain the code it would take to formalize [huh, did Kevin mean to write 'formalise'? :-)] say the proof of Fermat's last theorem.) Suggestions for that type of huge project is not what I am asking about here.&lt;/p&gt;&#xA;&lt;p&gt;What &lt;em&gt;is&lt;/em&gt; feasible, and what I am largely focused on here, is formalising deep mathematical &lt;em&gt;objects&lt;/em&gt;. For example, earlier this year I &lt;a href=&quot;https://github.com/kbuzzard/lean-stacks-project&quot; rel=&quot;nofollow noreferrer&quot;&gt;formalised the definition of a scheme&lt;/a&gt;. For some other examples, including some personal experiences I've had in incorporating this sort of project in undergraduate education, please see my blog post.&lt;/p&gt;&#xA;&lt;p&gt;To put this in a greater context: many of us see ourselves as writing, as our spare time allows, the new Bourbaki in a formalised computer language. (This is bound to happen -- whether in Lean or some other framework, only time will tell.) So you could think of my question as basically asking: which chapters of Bourbaki we should be writing next? But especially with a focus on where they need to start: which key concepts, from chapters to be written, should we emphasise as the next candidates for &lt;em&gt;rigorous formalised definitions&lt;/em&gt;? Everything else would be built on that, with hard proofs following in the fullness of time.&lt;/p&gt;&#xA;&lt;p&gt;(If you want to understand better what exactly would be involved in doing this sort of thing, please feel free to ask the growing community at &lt;a href=&quot;https://leanprover.zulipchat.com/&quot; rel=&quot;nofollow noreferrer&quot;&gt;the Lean prover Zulip chat&lt;/a&gt;.)&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I think this might go over better, but Kevin and Federico and Neil should let us know what they think about this.&lt;/p&gt;&#xA;" OwnerUserId="2926" LastEditorUserId="-1" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2018-10-18T15:49:48.083" CommentCount="7" ContentLicense="CC BY-SA 4.0" />

He suggested to create a new tag &quot;scottish-book&quot;, which indeed has more sense than &quot;lviv-scottish-book&quot;, which of course can be recovered from the account of the Lviv Scottish Book. In fact during the history there existed at least three Scottish Books: the original Lwow &quot;Scottish Book&quot; (1935-1941) with 193 problems, The Wroclaw &quot;New Scottish Book&quot; (1946-1987) with 968 problems, and the &quot;Lviv Scottish Book&quot; (2014--??) which has at the moment 23 problems, written to MO + 2 solved (without inscribing to MO). So the tag &quot;scottish-book&quot; would be just an indication that the problem can have some relation to one of these 3 Scottish books.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;I am not sure this is a good idea, for a couple reasons. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;First of all, while there is some internal logic to adding the tag more generally than the single user's questions, it seems to be a solution looking for a problem: there are rather few questions of this category that could be usefully tagged this way (other than going through the userpage of &lt;a href=&quot;https://mathoverflow.net/users/105651/lviv-scottish-book&quot;&gt;Lviv Scottish Book&lt;/a&gt;), and in any case one can find all of them by performing a search for &lt;a href=&quot;https://mathoverflow.net/search?q=%22scottish%20book%22&quot;&gt;&quot;Scottish book&quot;&lt;/a&gt;, so the tag does not seem to have much functional purpose.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Secondly, there has already been a recent editing spree on these questions to add links to an online version of the &quot;Lviv Scottish Book&quot;, taking up some amount of space on the front page whenever this is done. Adding the tag just seems like another occurrence of the same.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Third, this is a meta tag, which does not actually give content about the mathematics of the post (but rather the metamathematics of where the question originated). It is my recollection that there is agreement these should be avoided, but I couldn't find a discussion of this in a quick search.&lt;/p&gt;&#xA;" OwnerUserId="40804" LastActivityDate="2018-10-28T18:57:14.033" CommentCount="6" ContentLicense="CC BY-SA 4.0" />

There is &lt;a href=&quot;https://math.stackexchange.com/questions&quot;&gt;Mathematics site&lt;/a&gt; in the Stack Exchange network &lt;a href=&quot;https://meta.mathoverflow.net/q/3760&quot;&gt;many other websites&lt;/a&gt; on the Internet.&lt;/li&gt;&#xA;&lt;li&gt;It can happen that your ban is lifted even without you doing anything - simply if enough users randomly stumble upon your post and upvote them. Here is an example from another site where this happened: &lt;a href=&quot;https://math.meta.stackexchange.com/q/24782#24784&quot;&gt;I have been banned from asking questions, what should I do?&lt;/a&gt;. (It is natural that your post on meta might attract some attention to your post on main. However, when I look at the reputation tab in your profile, it seems that they lead to downvotes rather than upvotes.)&lt;/li&gt;&#xA;&lt;li&gt;I will repeat that according to &lt;a href=&quot;https://mathoverflow.net/help/question-bans&quot;&gt;the help center&lt;/a&gt;: &quot;If you're unable to improve your existing questions, you'll get the chance to ask a new one 6 months after your last question. If that question is positively received, you may be able to continue asking questions; if not, then the ban will be reinstated.&quot; So maybe a reasonable strategy would be simply to wait for 6 months. (And prepare a question about which you are confident that it is on-topic for the site and is going to be well received.)&lt;/li&gt;&#xA;&lt;li&gt;Both help center and FAQ mention editing your old question as a possibility to help. I will just add some caveat to be careful with this - and do it only if you are confident that you can get them into the shape suitable for MathOverflow. (Otherwise these action might have opposite effect - bumping the question might bring new attention to them and if MO users do not consider them of sufficient quality you will receive several new downvotes and you'll just dig yourself deeper into the question ban.) &lt;/li&gt;&#xA;&lt;li&gt;Take seriously &lt;a href=&quot;https://meta.stackexchange.com/questions/179087/warn-new-users-when-they-ask-a-question-after-a-previous-question-is-closed-dow/231118#231118&quot;&gt;warnings displayed by the system&lt;/a&gt;. If from a warning (on from your past experience) you suspect that you might be close to to triggering question ban, before posting the next question it might be useful to reread: &lt;a href=&quot;https://meta.mathoverflow.net/q/882&quot;&gt;How to write a good MathOverflow question?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2018-11-18T12:23:21.593" LastActivityDate="2018-11-18T12:23:21.593" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

A few of them include:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Top banner is shorter in height, so some artwork has to be adjusted along with some logos.&lt;/li&gt;&#xA;&lt;li&gt;Left Navigation is active everywhere (but can be collapsed into a menu by visiting your site preferences - &lt;a href=&quot;https://meta.stackexchange.com/a/311237/284336&quot;&gt;instructions here&lt;/a&gt;).&lt;/li&gt;&#xA;&lt;li&gt;Responsive layout is active, which lets the site adjust as browser widths change - no side scrolling (some pages haven't been updated, yet, though). For now, if you prefer the scrolling, you can disable this by clicking the &quot;disable responsiveness&quot; link in the footer.&lt;/li&gt;&#xA;&lt;li&gt;Many site elements including tags and voting arrows are standardized across the network.&lt;/li&gt;&#xA;&lt;li&gt;Link underlining is active.

Some stuff can be edited by site moderators - a more detailed description can be found here: &lt;a href=&quot;https://meta.stackexchange.com/q/259914&quot;&gt;What parts of the help center can site moderators edit?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;Based on &lt;a href=&quot;https://chat.stackexchange.com/transcript/20352?m=45173468#45173468&quot;&gt;anecdotal evidence&lt;/a&gt; it seems that sometimes Stack Exchange makes more pages mod-editable than the default settings (on moderators' request).&lt;/p&gt;&#xA;&lt;p&gt;It seems to me very unlikely that regular users would be allowed to edit help center. (And it is probably quite a good thing, because those pages are - in a sense - &lt;em&gt;official&lt;/em&gt; and quite a lot thought should go into decision that something should be changed there.)&lt;/p&gt;&#xA;&lt;h2&gt;What should regular users do?&lt;/h2&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;If a regular (non-diamond) user wants to help, there is still plenty of stuff they can do. For example, many of the posts on meta tagged as &lt;a href=&quot;/questions/tagged/faq&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;faq&amp;#39;&quot; rel=&quot;tag&quot;&gt;faq&lt;/a&gt; or &lt;a href=&quot;/questions/tagged/faq-proposed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;faq-proposed&amp;#39;&quot; rel=&quot;tag&quot;&gt;faq-proposed&lt;/a&gt; are community wiki, mainly to encourage editing by users.&lt;sup&gt;1&lt;/sup&gt; You can also edit tag-infos - both on main and on meta, but tag-infos on meta are quite a good place where to collect relevant information for some topic related to usage of the site.&lt;sup&gt;2&lt;/sup&gt; (For example, if you can see some useful additions to the&#xA;&lt;a href=&quot;https://meta.mathoverflow.net/tags/badges/info&quot;&gt;tag-info for badges tag&lt;/a&gt;, you can edit the tag-info.)&lt;/li&gt;&#xA;&lt;li&gt;If a regular user wants to suggest some change to help center, the right approach is to bring this up on meta. For things specific to MathOverflow, the suitable place is this meta. But for stuff that is relevant for all sites in the network, &lt;a href=&quot;https://meta.stackexchange.com/&quot;&gt;Meta Stack Exchange&lt;/a&gt; is the right place. (In the examples below, you can see some posts of this type.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;h2&gt;Badges descriptions&lt;/h2&gt;&#xA;&lt;p&gt;You also mentioned that you were interested specifically in badges.&lt;/p&gt;&#xA;&lt;p&gt;For several badges you can quite easily see your progress towards particular badge, the easiest way is probably using badge tracker in your profile (although not all badges are displayed there). For more details see: &lt;a href=&quot;https://meta.stackexchange.com/tags/badge-progress/info&quot;&gt;https://meta.stackexchange.com/tags/badge-progress/info&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;In the network-wide FAQ you can find this post which has more detailed description than help center: &lt;a href=&quot;https://meta.stackexchange.com/q/67397&quot;&gt;What are the badges I can earn on each site, and what are the exact criteria for earning each badge?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;h3&gt;Socratic badge&lt;/h3&gt;&#xA;&lt;p&gt;For more detailed description of the criteria for asking badges (&lt;a href=&quot;https://mathoverflow.net/help/badges/200/curious&quot;&gt;Curious&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/help/badges/201/inquisitive&quot;&gt;Inquisitive&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/help/badges/202/socratic&quot;&gt;Socratic&lt;/a&gt;) you can read he description in this post: &lt;a href=&quot;https://meta.stackexchange.com/q/234259&quot;&gt;Asking days badges&lt;/a&gt;. I will also point out that the wording was updated after this discussion: &lt;a href=&quot;https://meta.stackexchange.com/q/234956&quot;&gt;Misleading description of new Curious badge&lt;/a&gt;. (I found both those links from a question which is very similar to yours - just posted on the main meta: &lt;a href=&quot;https://meta.stackexchange.com/q/283813&quot;&gt;Definition of a 'well received question' for the purposes of the Curious badge&lt;/a&gt;.)&lt;/p&gt;&#xA;&lt;h3&gt;Illuminator badge&lt;/h3&gt;&#xA;&lt;p&gt;Since &lt;a href=&quot;https://mathoverflow.net/help/badges/215/illuminator&quot;&gt;Illuminator badge&lt;/a&gt; was mentioned in the comments, I will add a link to a related discussion on another meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/22676&quot;&gt;Refiner and Illuminator badges confusing&lt;/a&gt;. The badges &lt;a href=&quot;https://mathoverflow.net/help/badges/213/explainer&quot;&gt;Explainer&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/help/badges/214/refiner&quot;&gt;Refiner&lt;/a&gt;. Clearly, the description doesn't mean that you have to answer and edit 500 question within twelve hours. If on &lt;em&gt;a single question&lt;/em&gt; you do those two actions (post answer that reaches positive score and also edited the question) and these two actions are within 12 hours of each other, the counter describing your progress increases by one. (As already mentioned, you can check your progress towards those badges using badge tracker in your profile - unless you already have that badge.)&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt; In general, FAQ on meta are easier to update than help center. So this is probably better way for information that might change often. (Just as an example I will mention that in the part of the help center &amp;quot;&lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;What kind of questions should I not ask here?&lt;/a&gt;&amp;quot; there are several clearly outdated links. For example, neither &lt;a href=&quot;http://mathforum.org/dr/math/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Ask Dr. Math&lt;/a&gt; nor &lt;a href=&quot;https://nrich.maths.org/discus/messages/board-topics.html&quot; rel=&quot;nofollow noreferrer&quot;&gt;NRICH&lt;/a&gt; can be now used to ask question, yet they are still listed in the help center. I would hope that &lt;a href=&quot;https://meta.mathoverflow.net/questions/3760/my-question-was-closed-on-mo-because-it-is-not-research-level-where-should-i-as/3761#3761&quot;&gt;a corresponding post on meta&lt;/a&gt; would be updated more promptly in such cases, since it can be edited by any user with sufficient reputation.)&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt; The tag-info should be used for guidance when to use the tag. But probably it might be good idea also to store there the most relevant links related to the specific topic described by the given tag. To name just one example, when I mention Data Explorer here on meta I typically include &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;the link to tag-info&lt;/a&gt;. This has the advantage that users reading the post have quick access to some basic information - and if some of that information changes it suffices to update it in a single place (in the tag-info) and not in every question.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="-1" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2018-11-20T08:28:00.377" CommentCount="1" ContentLicense="CC BY-SA 4.0" />

In this regard, MathOverflow is different. (It is listed also in the network-wide FAQ among exceptions: &lt;a href=&quot;https://meta.stackexchange.com/q/58587#160292&quot;&gt;Reputation requirements compared&lt;/a&gt;, &lt;a href=&quot;https://meta.stackexchange.com/revisions/160292/56&quot;&gt;current revision&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As far as I can tell, this was changed mainly to help during the transitional period when MO was being migrated to Stack Exchange network, when several users might have had various problems. The relevant discussion can be found here: &lt;a href=&quot;https://meta.mathoverflow.net/q/33&quot;&gt;Allow posting on meta without any reputation for the first week&lt;/a&gt;. You may notice that the feature request there starts with: &quot;Would it be possible to remove the reputation requirements for posting on meta for the first week, while we iron out all the login problems people are having?&quot; So from the start on this was probably intended just as a temporary thing.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I'd guess that since several years have passed since then, this is probably no longer needed to help users with the transition to the new network. And there are also some disadvantages to lowered reputation requirements for posting on meta.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Users unfamiliar with this site might post completely off-topic stuff on meta. (5 reputation points are not that much, but at least the user has to do something on the main site and gets at least very basic knowledge of MO. Recently we have seen several rather off-topic posts on meta. To include just two very recent and very off-topic examples, here are two questions that were posted not too long ago: &lt;a href=&quot;https://meta.mathoverflow.net/questions/3975/please-steer-me-toward-a-legal-organisation&quot;&gt;Please steer me toward a legal organisation&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/questions/3968/i-need-your-help-for-a-new-theory&quot;&gt;I need your help for a new theory&lt;/a&gt; . Both of them are now deleted, but users who visit meta probably remember them - IIRC on one of them there was even a comment that the post is a perfect example of an off-topic question.)&lt;/li&gt;&#xA;&lt;li&gt;First time posters can easily post on meta instead on main by mistake.&lt;/li&gt;&#xA;&lt;li&gt;There is no post ban on meta. So somebody who is banned from asking on main site can simply continue posting on meta. (They do not get any answer and might eventually get suspended, but still something like this might be quite irritating.)&lt;/li&gt;&#xA;&lt;li&gt;This is one of the very few meta sites where I saw spam posted - typically users posting spam have accounts created solely for that purpose so they start with reputation 1. And since meta is visited less that the main site, it might take longer until the spam post is flagged and removed. (Well, I only saw three spam posts on this meta in total, but still... it would be better if there were none of them.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Proposal:&lt;/strong&gt; I suggest to change this back to 5 reputation points - as on other sites. (Unless the discussion here shows that there are some strong objections against this from the MathOverflow community or from the moderators.) &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;&#xA;Personally, I considered this to be change where it is clear-cut that it is better to change this back to the normal state. But since the moderators responded neither to &lt;a href=&quot;https://meta.mathoverflow.net/questions/33/allow-posting-on-meta-without-any-reputation-for-the-first-week?noredirect=1&amp;amp;lq=1#comment15806_33&quot;&gt;the comments in the old discussion&lt;/a&gt; suggesting the change nor to my &lt;a href=&quot;https://chat.stackexchange.com/transcript/9369/2018/11/16&quot;&gt;recent inquiry in chat&lt;/a&gt;, perhaps this is not so clear cut as I thought and it should be discussed first before the change is made; if only to find out whether there is some support for this idea.

At that point, the 5 items easily fit next to each other at the top, leaving much less unused space.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&lt;strong&gt;Question 2.&lt;/strong&gt; How were the responsive design cutoffs chosen?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;The left nav isn't hidden until you get down to 640px, but the spacing has been uncomfortable for a while in the 641-700px range (specifically: the main content gets squeezed to too small a portion of the screen). To me, 700px (or even 720px) would seem a better cutoff. For example, this is the page at 650px; you look me in the eye and tell me this is good design.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/aZHiL.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/aZHiL.png&quot; alt=&quot;Width 650px&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Similarly, the 980px cutoff for the right panel leaves a range (981-1040px) where the main content in fact takes up less than 50% of the full width. For example, at 1000px we get the following:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/2cztm.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/2cztm.png&quot; alt=&quot;Width 1000px&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Firefox's Inspector reveals that the &lt;em&gt;mainbar&lt;/em&gt; div (i.e. question and answer with vote buttons) totals 462px, which is less than half the available width. The actual text only gets 401px out of the available 1000px.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(Note that full screen tablets and smartphones are not the only way smaller window sizes come about, and a website should be well-designed for &lt;em&gt;every&lt;/em&gt; window size.)&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&lt;strong&gt;Question 3.&lt;/strong&gt; Why are question titles wrapped mid-word?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;This looks like a bug to me. At the very smallest of scales I can see why this is helpful &lt;em&gt;given the other design choices&lt;/em&gt; (especially the insistence on the 'Ask question' button to stick around), but at intermediate to full scale it's not clear to me that this is helpful. For example, at 320px we get the following:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/EARct.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/EARct.png&quot; alt=&quot;Width 320px&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Here is a question with a longer title at 320px (also raising the question why the 'Ask question' button needs to be there).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/FRxNK.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/FRxNK.png&quot; alt=&quot;Longer title&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;See also the 650px and 1000px pictures above.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(I did not have to search very hard to get these behaviours to show up.

They could be different numerical quantities (usually a stand in for a real number, although sometimes a complex or a rational or integral number), or some other object (an indeterminate, or random variable, or abstract space or algebraic entity). As a result, X is loosely associated with the thing it represents. (I am going to be vague and ignore the philosophical question of whether different occurrences of X are distinct or are just the same symbol appearing at different times in a narrative. For this narrative, X behaves as a unique entity as symbol.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Not all symbols are mathematical in nature. There is a symbol that bothers me. I will call it W. It is a trigger for me. When it is used, I believe the person expressing it is using it for hate and for nothing else. In my view, this symbol is strongly associated with hate.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I believe the (former) avatar of Patriot is a symbol which is a trigger for many. I don't care to trigger other people, so I am for the case of not seeing this symbol anywhere on MathOverflow.  However, this avatar is not a trigger for me.  If I see it somewhere else, I either ignore it or avoid it. There are other actions I could take, but much of the time I do not see the benefit, and so do not.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I do not want to change the relationship between other people and their triggers. I am willing to do some accommodation for triggered people, especially if it means removing the trigger.  I am willing because the hate that pours from them after they are triggered is more than I am willing to bear.  Give them space for an emotional release, then move on to the business of the forum.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think Todd Trimble seriously W up. (I think I did too, but in a more subtle fashion.) Whatever his personal feelings may be, as moderator his response should have been and should be more moderate, accommodating the fact that some people are triggered and some people are not. The assumption that everyone should be triggered and triggered in the same way suggests to me a tone of intolerance and hatred, and I am bothered by it. Some of the subsequent comments and posts show this tone as well.  I do not feel safe in making statements on this thread. I do feel this post I make here needs to be made.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;How did I W up? By dealing with triggered people in an oppositional fashion. Rather than being acutely aware of the situation and working on mollifying or at least staying silent, I decided to assert that the avatar is not a trigger for everyone, and that this should be acknowledged by the moderator.  I tried to be moderate and nonconfrontational, and I failed.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Thanks for reading this far. What should be the takeaway?  If we are to continue as a community to espouse certain ideals, we should take care of one another.  I am very bothered by the post of Noah Snyder, not because of his assertion of his position, but because of the hate and intolerance I sense in it. I suspect he would not have even made it if I had not made my comment; this idea saddens me. Although I don't want to see hate (and I am not that fond of racism or slavery or White supremacy either) on this forum, I am going to see it from triggered people.  If I am more aware, I will defer the fight of &quot;non-triggered people are people too&quot; in favor of having someone care for the triggered person.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have more to say, but I will end up answering the question.  Triggers on MathOverflow are to be avoided, not because certain causes should or should not be espoused, but because one can't do mathematics while triggered. While I am not triggered by the avatar, I support the removal of the avatar, and hope the user approaches this forum with mathematics and a more moderate presence. We should welcome the mathematics that is suitable for this community, and handle in a moderating fashion any mathematics which is not suitable. (Maybe someday we will decide what suitable mathematics looks like and agree upon that.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In the case triggers do appear, they should be handled differently than was handled here. A small amount of competent moderation should be able to defuse the situation.  I hope this is a learning example for others as well as for me.  I apologize for my part in the prolongation of the hate.

But since you're talking about an answer to your question posted &lt;em&gt;by another user&lt;/em&gt;, you do not get automatically the notifications about all comments. So if somebody comments under that answer (or more generally under some other users' post), if you also posted a comment there, they can notify you by using the &lt;code&gt;@username&lt;/code&gt; syntax.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There is one exception when this is actually not needed, I will quote from the linked FAQ post:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Note that if a user comments on their own post and there is only one other person who has previously commented on that post, then that person is &lt;a href=&quot;https://meta.stackexchange.com/questions/82134/micro-refinement-to-notifications-for-comments-of-others-posts&quot;&gt;also notified&lt;/a&gt;, even if &lt;em&gt;@name&lt;/em&gt; is not used. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;So as long as you and the post author (in this case the answerer) are the only users who posted comments there, you should get a notification. (However, this is not the case for the answer in the linked question.)  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Looking at the comments which are displayed at the moment under &lt;a href=&quot;https://mathoverflow.net/questions/316524/2-fiber-product-is-a-scheme-then-map-of-stacks-is-representable/316738#316738&quot;&gt;the answer in question&lt;/a&gt;: &lt;a href=&quot;https://mathoverflow.net/questions/316524/2-fiber-product-is-a-scheme-then-map-of-stacks-is-representable/316738#comment790686_316738&quot;&gt;The first comment&lt;/a&gt; by the answerer explicitly used &quot;@PraphullaKoushik&quot; - so you should be notified of that one.

The post linked to above is the place to give &quot;feedback&quot; to StackExchange about the new look. But I think in order to give adequate feedback, we need a better understanding of what is going on.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So here are a few more basic questions:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;What is the timeline for this process as regards MO specifically?&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;More specifically, when does the new theme exit beta mode and become live? Weeks? Months? Years from now?&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;The beta version of the new theme is not the final version apparently -- in the future, we're supposed to hear about options for customizing off of this core. But apparently StackExchange doesn't even know what the options are going to be yet. &lt;a href=&quot;https://meta.stackexchange.com/questions/319274/responsive-design-themes-what-can-sites-customize-and-how-can-they-get-changes&quot;&gt;This&lt;/a&gt; references a timescale of &lt;em&gt;6-8 years&lt;/em&gt; over which they foresee customization options evolving. So apparently this is going to be a complex process. But for the first step, I'd really like to know: &lt;/p&gt;&#xA;&#xA;&lt;ol start=&quot;3&quot;&gt;&#xA;&lt;li&gt;What customization options will be available to us &lt;em&gt;before&lt;/em&gt; the new theme goes live (i.e. which customization options can we have active on the first day the new theme goes live)?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;I'm assuming that the answer will at least be &quot;a nonzero number of options&quot;, because I'm assuming that nobody at MO or at StackExchange wants a scenario where the live version of the website is a cookie-cutter plain vanilla theme which looks exactly the same as every other StackExchange site.&lt;/p&gt;&#xA;&#xA;&lt;ol start=&quot;4&quot;&gt;&#xA;&lt;li&gt;What will the process be for deciding which customization options we want to use before the new theme goes live?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;From the look of the meta post I linked to at the top, there are a lot of feelings out there about what the site should look like. As mathematicians, nobody really wants to spend too much energy hashing this stuff out, but I would have anticipated a process a little more structured than just &quot;give us constructive feedback in response to this meta post&quot;.&lt;/p&gt;&#xA;&#xA;&lt;ol start=&quot;5&quot;&gt;&#xA;&lt;li&gt;&lt;p&gt;What will the process be going forward for deciding about future customization options as they become available?&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Who is the person with primary responsibility for the look and feel of MO under the new theme? Is it Jon Ericson, who posted the first meta post?&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;I can't envision this process working smoothly without there being an individual at whose desk the buck stops on these things -- whether it's  a StackExchange employee, a moderator, or whoever, it seems to me there should be a point person.&lt;/p&gt;&#xA;" OwnerUserId="2362" LastEditorUserId="2362" LastEditDate="2018-12-09T09:51:55.403" LastActivityDate="2018-12-14T21:10:28.070" Title="What is the plan for the new site theme?"

Several issues with the new theme were raised in that discussion. I'd like to discuss one of them, which is sort of buried in &lt;a href=&quot;https://meta.mathoverflow.net/questions/3976/mathoverflow-updated-site-theme-is-ready-for-testing/3988#3988&quot;&gt;my answer&lt;/a&gt; and David Roberts' comment to the answer. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(My understanding from &lt;a href=&quot;https://meta.stackexchange.com/questions/319274/responsive-design-themes-what-can-sites-customize-and-how-can-they-get-changes&quot;&gt;this post&lt;/a&gt; is that this is StackExchange's plan for dealing with problems arising from the new theme -- to raise them in meta questions. See that post also for discussion of what customization options are available.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;What I'd like to discuss is the following problem:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;In the new design, MO looks more similar to MSE than it used to. How can we change this?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;This feels like an important issue to me, because &lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;As David Roberts pointed out, new users already have enough difficulty understanding the difference between the two sites.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Many people (like me) are frequent users of both MO and MSE, and I for one would appreciate having more visual cues to remind me which site I'm on.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;My general sense is that what used to distinguish MO from MSE was that MSE had the feel of a general StackExchange site with a few customizations whereas MO had a minimalist feel that somehow reflected its independent origins -- an approach that seems to be specifically ruled out in the new design theme.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Therefore I think it's worth considering trying to attain some sort of altogether new look. But I'm not sure what that should be.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Screenshots&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Here are screenshots of the front page for comparison:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/R3PPb.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/R3PPb.png&quot; alt=&quot;MO front page&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/qXLZ0.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/qXLZ0.png&quot; alt=&quot;MSE front page&quot;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are certainly differences, though they are subtle:&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;The headers: one says &quot;mathoverflow&quot; while the other says &quot;mathematics&quot;. Of course, this disappears as soon as you start scrolling down.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The background: MO is plain while MSE has their graph paper theme. Once you start scrolling down, this is only visible in the far left region of the page.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The &quot;Ask Question&quot; button: orange for MO, navy for MSE. This also disappears once you scroll down.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;In the tabs for which questions you want to view: &quot;Active&quot; for MO, &quot;Interesting&quot; for MSE. Disappears when you scroll down.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Tags: white with an outline and black text for MO, light blue with dark blue text for MSE.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Text: Blue sans serif for MO, black serif for MSE.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&quot;Hot Network Questions&quot;: not present on MO (replaced by &quot;Recent Tags&quot; and &quot;Recent Badges&quot;), present on MSE. (Not visible in these screenshots -- this is in the lower right part of the screen.) I'm very glad that this distinction is maintained from the old theme!&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;I could go on to the interface for asking a new question or viewing an existing question, but the similarities and differences there are really of the same flavor.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;What used to distinguish the two sites?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Well, I no longer have access to the old looks of the two sites, so I'm going by memory here.&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Carlo Beenakker &lt;a href=&quot;https://meta.mathoverflow.net/a/3978/2362&quot;&gt;points out&lt;/a&gt; that MO used to have a distinctive color scheme to distinguish questions which were unanswered / answered / answered and accepted.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;მამუკა ჯიბლაძე and GNiklasch &lt;a href=&quot;https://meta.mathoverflow.net/a/3980/2362&quot;&gt;point out&lt;/a&gt; that MO used to have a color scheme highlighting accepted answers.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&quot;Home&quot;, &quot;Questions&quot;, etc. on the left navigation bar used to be at the top of the page, and I believe MO had a different color scheme for them than MSE did. I'm not sure, but I think these screen elements used to remain at the top when you scrolled down?&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I think the graph paper background on MSE used to be visible across more of the screen than it is currently (Now as soon as you scroll down, it's visible only at the far left of the screen).&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Overall, I think that MO used to have an &quot;orange and green&quot; feel whereas MSE had a &quot;red and blue&quot; feel. Now both of them feel mostly colorless to me.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I'm not sure, but I think before the left navigation bar was there maybe MO's questions were more flush to the left than MSE's?&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;In general, I think the old differences were quite subtle, and reflected MO's independent origins.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Some suggestions:&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Here are my two cents on things we might consider:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;We might consider some kind of header / background beyond the plain look we've always had.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;We might consider asking to re-implement some of the old color distinctions like with unanswered / answered / answered and accepted questions.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;It sure would be nice if more of the distinctive design elements remained visible when one scrolled down. As it is, the parts of the site which travel with you when you scroll are the black bar at the top and the left navigation column. The only customization I see in these elements is the background (graph paper for MSE) which appears on the left navigation.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Maybe we should consider having the words &quot;research mathematics&quot; appear somewhere on the front page? As it is, I don't think it really jumps out from the main page that that's the purpose of this site.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;EDIT:&lt;/strong&gt; In the interest of gauging people's interest, I'm going to start throwing some answers up here.

I already did so this evening in an attack of nostalgia :)&quot; Or, as another example, I have seen that somebody uses a script which gives specific colors to &lt;a href=&quot;https://stackapps.com/questions/3230/color-tags-script&quot;&gt;tags of their choice&lt;/a&gt;.

(Especially Mathematics was mentioned a few times, probably because there are many people who visit both MathOverflow and Mathematics relatively often. This was discussed mainly here: &lt;a href=&quot;https://meta.mathoverflow.net/q/4004&quot;&gt;How can we visually differentiate MathOverflow from MathStackExchange within the constraints of the new design themes?&lt;/a&gt;) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;From what I gathered so far, there are some options how to customize the look of the site, but it might take quite a long time before this happens. (Based on the comments from the CMs we are probably talking weeks or months.) It seems that at the moment the process is in the stage of collecting feedback.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One option is to make a few some simple changes now - ideally something that would at least help to distinguish the two sites a bit. (It would be probably best to leave the choice up to the Stack Exchange DAG team.&lt;sup&gt;1&lt;/sup&gt; Of course, they probably will take into consideration also the suggestion mentioned so far in meta.) And then - at some later point - a more thorough design change would come, taking into account the feedback from MO community collected here on meta.&lt;sup&gt;2&lt;/sup&gt; &lt;/p&gt;&#xA;&#xA;&lt;p&gt;This could possibly help to satisfy those users who do not like the fact that the two sites look too similar. Some posts on meta suggest that at least some of the users are already becoming a bit impatient.&lt;sup&gt;3&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;TL:DR;&lt;/strong&gt; What do you think about the possibility of making a few minor changes now - just to distinguish MathOverflow from Mathematics. With the understanding that this is only a temporary solution and a nicer design will come later.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;As far as I can tell, the &lt;a href=&quot;https://meta.stackoverflow.com/questions/351751/meet-team-dag-developer-affinity-growth&quot;&gt;DAG Team&lt;/a&gt; is most likely responsible for the final version of the site design. Or at least they seem to be the people who are dealing &lt;a href=&quot;https://meta.stackexchange.com/questions/305560/2018-monthly-product-team-updates&quot;&gt;with the responsive design quite a lot&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;If you want you can look a brief discussion about this I had with Catija in chat. It was mentioned there that there is some stuff which can be mentioned relatively quickly. It starts &lt;a href=&quot;https://chat.stackexchange.com/transcript/message/48111569#48111569&quot;&gt;at this message&lt;/a&gt;. (And there are also a few more discussions about the new design in chat - looking at the &lt;a href=&quot;https://chat.stackexchange.com/rooms/info/9369/mathoverflow?tab=stars&quot;&gt;starred messages&lt;/a&gt; can give you a brief idea what was mentioned and of course you can browse a bit through the transcript from the recent days. Unless I missed something, the recent discussion of this topic in the MathOverflow chatroom started from &lt;a href=&quot;https://chat.stackexchange.com/transcript/9369/2018/12/13&quot;&gt;December 13&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;3&lt;/sup&gt;I will admit that it is difficult to judge to which extent the MO users are not satisfied with the new look - since we only hear from the users who came to discuss on meta.

It is probably viewed quite a lot, since one of the close reason which is quite often used links to this page: &quot;This question does not appear to be about research level mathematics within the scope defined in the &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;help center&lt;/a&gt;.&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This particular page in the help center is editable by moderators.&lt;sup&gt;1&lt;/sup&gt; The FAQ post on meta is editable by regular users (with sufficient reputation), but the intention is probably to have the same wording in both places.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As you can see, several of the links given there are outdated for some time.

In the &lt;a href=&quot;http://mathforum.org/dr.math/faq/&quot; rel=&quot;nofollow noreferrer&quot;&gt;FAQ for Ask Dr. Math&lt;/a&gt; you can see the following text: &quot;We will no longer be accepting new questions for this service starting on October 31, 2017.&quot; And on the &lt;a href=&quot;https://nrich.maths.org/discus/messages/board-topics.html&quot; rel=&quot;nofollow noreferrer&quot;&gt;Ask NRICH site&lt;/a&gt; you can read that: &quot;Please note that the AskNRICH boards below closed on 31st July 2014.&quot; So those links actually do not serve the purpose for which they were included on this page.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Proposal:&lt;/strong&gt; I suggest to replace the text with some information that is more up-to-date. Moreover, to make this part of help center easier to maintain, I suggest that instead of listing the sites, the help center could link to a post on meta which contains some suitable sites. (In this way we achieve that even regular users can edit the list if some of the sites no longer works. And an additional advantage is that there is only one place which needs to be changed when there is a need for an update.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One possibility would be to use the answer to this question: &lt;a href=&quot;https://meta.mathoverflow.net/q/3760#3761&quot;&gt;My question was closed on MO because it is not research level.

(It is probably not worth to create a separate question for this - I am posting this suggestion as an answer, we'll see from the voting and the comments what MO users and moderators think about it.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is already possible to show various warnings depending on body, title and tags of the post. As far as I can tell, the warning is triggered depending on presence of some specific strings and it is possible to use regular expressions.&lt;sup&gt;1&lt;/sup&gt; From what I have seen in meta discussions, such warnings can be added by Stack Exchange staff. The request to do so quite often come from the mods, more often than not after some discussion on meta.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Proposal.&lt;/strong&gt; I think that it should not be difficult to create a regex to find out whether a post contains an url containing the string proxy. In such case, a warning should be shown (with a short explanation that such links could be a possible problem and suggesting to the poster to check the links).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Disadvantages.&lt;/em&gt; This will create some false positives - which is the reason why I do not suggest to blacklist such input, just to show a warning. Also some users will probably ignore the warning - in such cases we have to rely on the fact that somebody notices the post and corrects the link. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Advantages.&lt;/em&gt; It is probably easier to create a check which might return some false positives but which should definitely catch most of the problematic links. (I would definitely consider this better than creating a separate regular expression for each proxy - assuming the numbers in &lt;a href=&quot;https://meta.mathoverflow.net/questions/3315/forbid-or-rewrite-proxy-links-in-answers/4051#4051&quot;&gt;the CW answer&lt;/a&gt; are close to correct, then by creating a regular expression which in some way handles a specific proxy we would help with at most 5 posts. I don't think that this is worth the effort - MO would need for each specific proxy go through moderators and ask somebody from Stack Exchange to add it to the list.) Unless there is some way which would take care of &lt;em&gt;many proxies&lt;/em&gt; at the same time - which seems unlikely to me - this seems to me much simpler solution than trying to implement some way to automatically rewrite such links, considering the number of posts where this is actually a problem.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;If I find some place where this is documented in detail, I can add it here.

Some of these tasks could be done by Stack Exchange the company, but they simply &lt;a href=&quot;https://meta.stackexchange.com/q/303005/295232&quot;&gt;lack the budget and/or (wo)manpower&lt;/a&gt; to do so. I'm not asking for permission from every single community, as that would amount to me having to post 173 questions on each single meta site. I've pointed out some means to contact me on the GitHub page, but this Meta post will do fine; thanks @MartinSleziak for notifying me about this post.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You're right that as part of the transition from HTTP and HTTPS, all HTTP links to sites inside the Stack Exchange network were &lt;em&gt;automatically&lt;/em&gt; rewritten to HTTPS by a script made by Stack Exchange employees. However, that was a relatively simple script; it did not check whether the target still existed, or could instead be retrieved via the &lt;a href=&quot;http://web.archive.org/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Wayback Machine&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One of the nice things about that script was that it didn't bump old posts; mine does (which is good, so other users can (re)view what it does), but there are &lt;a href=&quot;https://meta.stackexchange.com/q/238037/295232&quot;&gt;other scripts that bump things&lt;/a&gt; (&lt;a href=&quot;https://mathoverflow.net/questions/306466/parabolic-variational-inequality-regularity-of-the-time-derivative-in-l20-t&quot;&gt;recent example&lt;/a&gt;). If this community finds 1-3 bumps per 36 hours too annoying, I can decrease the frequency. Other conditions can be discussed; if, for example, the bot should only attempt to fix posts with a positive score, I can try to program those conditions into the bot. Switching it off entirely for MathOverflow is also an option, but to me that would be equivalent to a government ban on restoration of old paintings. For what it's worth, at this moment, 97.5% of the suggested edits by the bot have been approved (network-wide).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For the record, there are currently 41 posts left on MathOverflow which the bot will try to fix.&lt;/p&gt;&#xA;" OwnerUserId="70594" LastEditorUserId="70594" LastEditDate="2019-01-03T10:49:07.913" LastActivityDate="2019-01-03T10:49:07.913" CommentCount="13" ContentLicense="CC BY-SA 4.0" />

They also include attempts to prove the Riemann Hypothesis, or Goldbach's conjecture. Such topics tend to be &quot;crank magnets&quot;, and as professional mathematicians have long known, engaging with cranks can get to be extremely tiresome and distracting.

I was looking for references for something that is very clear and intuitive, but not really mentioned ANYWHERE. I got no answer, but a few comments which were also not satisfying. Time went on. I wrote the first reference and posted it as an answer, because I'm trying to be a good little SE member who doesn't abandon his own questions when he found an answer himself. Then, and only then (because the question was active again) I got some downvotes. I felt a little bit indignified, but ignored it, since it just means two or three particular people don't agree with me on the quality of my question and answer.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Today I saw the question was put on hold as off-topic by 5 users.

I looked into at least 20 books about graph theory in persue of a reference. There is none. I agree that the problem in the question is an easy one, that can be solved fast with a little bit of thinking. But it is not like I asked &quot;Does &lt;span class=&quot;math-container&quot;&gt;$\emptyset\subseteq A$&lt;/span&gt; hold for any set &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt;?&quot;, because THAT is mentioned in almost every book. My problem isn't anywhere.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So yes, a little bit indignified here. Given my medical circumstances it is good to write about it. But my main problem here, the one why I'm writing this meta question in the first place, is that I want to understand Math Overflow better. From my point of view, I had a question about basic research, which is, to my understanding, a legitimate area of research. &lt;strong&gt;Are basic research questions not wanted on Math Overflow?&lt;/strong&gt; Or is there another reason my question doesn't qualify?

Although this is probably not an easy thing to do, there are some reasonable options which might help a bit. For example, if you see an interesting featured question, you might &lt;a href=&quot;https://chat.stackexchange.com/rooms/info/9369/mathoverflow&quot;&gt;mention it in chat&lt;/a&gt;. (The same goes for any interesting question, regardless of bounties - and this might also increase awareness of the MathOverflow chatroom.) Some possible downsides of bounties and reasons why some user dislike them were mentioned in the comments - perhaps a separate discussion about pros and cons of bounties and how they can be used in a way useful for the site would be interesting and as a side affect it might attract more users to featured posts. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is also possible that some users will add featured questions to their &lt;a href=&quot;https://meta.stackexchange.com/q/312781&quot;&gt;custom question lists&lt;/a&gt; - this is a new feature which is &lt;a href=&quot;https://meta.stackexchange.com/questions/313940/custom-question-lists-is-available-for-testing&quot;&gt;currently being tested&lt;/a&gt; on a few Stack Exchange sites, but this new functionality should be available on all sites in the network at some point during this year. So this might also help the questions with bounties to get a bit more exposure.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Anyway, since we are discussing bounties, let me leave a few related comments.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Several users on MathOverflow expressed they dislike of reputation (and badges). So it's possible that some users can be put off by a bounty - since they do not want to make an impression that they are answering just because of the reputation points. (Although I only remember one case where removal of a bounty by a user who would receive it was requested. It was &lt;a href=&quot;https://math.meta.stackexchange.com/questions/3319/is-it-possible-to-remove-the-bounty-on-this-question&quot;&gt;on Mathematics&lt;/a&gt;, but the user in question is probably familiar to many MathOverflow users.)&lt;/li&gt;&#xA;&lt;li&gt;I would agree that a bounty on a question can indicate that it is an interesting question. The most frequent reasons that somebody offers a bounty seem to be: 1. The asker received no satisfactory answer for some time. 2. A user considers someone else's question interesting and wants attract more attention to it. 3. A user considers some answer exemplary and wants to reward the answerer. Each of these reasons correlate, to some extent, with some level of difficulty of interestingness of the question.&lt;/li&gt;&#xA;&lt;li&gt;Information that somebody offered a bounty does not go away after the bounty period ended. So it is possible that some users might use this information to find questions which had bounties. In particular, in the users profile there is &lt;a href=&quot;https://mathoverflow.net/users/current?tab=bounties&quot;&gt;bounties tab&lt;/a&gt; which shows both offered and earned bounties by a specific users. (And it would not surprise me if somebody occasionally looked at profile page of another user who has similar interests or who is a well-known expert in some area - to see which questions they asked, answered or even where they offered a bounty.)&lt;/li&gt;&#xA;&lt;li&gt;It is possible to find past bounties using &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;Data Explorer (SEDE)&lt;/a&gt;. Some queries which can be used for this purpose are listed &lt;a href=&quot;https://meta.mathoverflow.net/questions/3539/what-would-be-good-place-to-list-unresolved-bounties/3540#3540&quot;&gt;in this answer&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;As an experiment, some time ago I started a chatroom called &lt;a href=&quot;https://chat.stackexchange.com/transcript/70737/2017/12/24&quot;&gt;Listing bounties&lt;/a&gt;. (Partially in connection with my post: &lt;a href=&quot;https://meta.mathoverflow.net/q/3539&quot;&gt;What would be good place to list unresolved bounties?&lt;/a&gt;) This room should contain most (almost all) featured questions since the time it was started. The intention was to make the bounties easier to search and shown in a more user friendly format. (In chat, you can see a preview of the question. You can easily search for past bounties in a specific tag or with the title containing some keyword.) Of course, one can imagine also various other technical solutions to create some list of past bounties where the format would be more user-friendly and which would be easier to search than the results from SEDE.&lt;/li&gt;&#xA;&lt;li&gt;The observation (&lt;a href=&quot;https://meta.mathoverflow.net/questions/4066/giving-bountied-questions-more-visibility-weight#comment18158_4066&quot;&gt;made in the comments&lt;/a&gt;) that many of the bounties are offered by (relatively) low rep users to attract attention to their post is definitely correct. However, bounties can also be used to make the best content of the site more visible. (I have seen some bounties on MathOverflow which were offered to reward an existing answer - which seems to be in the similar spirit. Of course, users who have more reputation have wider possibilities to do something in this direction.) I will mention that on Mathematics site some moderators and experienced users have recently discussed the use of bounties to highlight the site's best contest - as you can imagine, on a high traffic site many good posts can go unnoticed. There are plans to start a separate chatroom devoted to this and it should probably be launched at some point during this year.

(Of course there are also other &lt;a href=&quot;https://tex.stackexchange.com/tags/commutative-diagrams/info&quot;&gt;LaTeX packages for commutative diagrams&lt;/a&gt;, the most popular probably are tikz-cd and xy-pic.)&lt;/li&gt;&#xA;&lt;li&gt;The code is compiled online and it generates picture which can be used elsewhere. (Naturally, some users might prefer to do this locally on their computer and convert the output from LaTeX to picture by themselves.)&lt;/li&gt;&#xA;&lt;li&gt;If you add link to the website, you simultaneously provide the xypic code.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;I will explicitly mention that images uploaded through the editor should be stable and relatively immune to link rot, see: &lt;a href=&quot;https://math.meta.stackexchange.com/q/4205&quot;&gt;Permanent Picture Uploads&lt;/a&gt; (Mathematics Meta).&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;I am fully aware that this is not optimal from the viewpoint of &lt;a href=&quot;https://en.wikipedia.org/wiki/Screen_reader&quot; rel=&quot;nofollow noreferrer&quot;&gt;screen readers&lt;/a&gt; and visually impaired users.

But as I understand it, the general principle, which actually applies to all sites in the StackExchange network, is to have crisp and to-the-point question-answer interchanges based on facts (verifiable if possible). In fact the software is designed to avoid long, rambling discussions or arguments.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;How this plays out in practice is site-dependent. We occasionally have for example questions that ask for advice (on co-authoring papers, say, or textbooks for a certain course). Some of those remain open, some are closed. It's hard to say exactly where the dividing line is, but one factor may be asking questions based on personal experiences (hence factual) as versus others which are primarily opinion-based. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Echoing the question of მამუკა ჯიბლაძე (Mamuka Jibladze), it might be easier to address this question with actual examples in mind.

In many cases people who are familiar with the area know the intended usage just from the tag name. So this is more important if the tag-name is ambiguous&lt;sup&gt;1&lt;/sup&gt; or might be misunderstood by a non-expert.&lt;sup&gt;2&lt;/sup&gt; See also: &lt;a href=&quot;https://meta.stackexchange.com/q/214337&quot;&gt;What is a tag wiki? How do I write a good one?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The tag-wiki might be a good place to give some pointers to good resources about the topic and a very brief overview what the topic is about. (However, it is probably not suitable for a full blown introduction for some topic - similar to a Wikipedia or nCatLab article.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is great if some people do this - editing and improving tag-infos should certainly be encouraged. However, it seems that not many users of this site find the time to do this.&lt;sup&gt;3&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Regarding a comment asking somebody to edit tag-info for a specific tag - I have certainly posted several such comments, you can find some of them &lt;a href=&quot;https://chat.stackexchange.com/search?q=unless&amp;amp;room=10243&amp;amp;user=11287&quot;&gt;archived in chat&lt;/a&gt;. However, it was slightly different situation - my comment was typically addressed to the user who created the tag. And the intention was mainly to have some guidance for the usage of the new tag on the site.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;A good example is that there are several tags for lattices - this word is used in several different meanings in mathematics. There were at least three posts on meta about this - &lt;a href=&quot;https://meta.mathoverflow.net/questions/194/help-improve-tagging/1761#1761&quot;&gt;in 2014&lt;/a&gt;, &lt;a href=&quot;https://meta.mathoverflow.net/questions/862/help-cleanup-tags/1407#1407&quot;&gt;in 2015&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/questions/2791/what-lattices-do-we-need&quot;&gt;in 2016&lt;/a&gt;. The situation about tagging questions about these topics doesn't seem to be satisfactorily resolved.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;A good example is the tag (divisors). As you can see &lt;a href=&quot;https://mathoverflow.net/posts/154958/revisions&quot;&gt;from the tag-info&lt;/a&gt; the tag is intended for divisors in algebraic geometry. But it is not surprising that some users just look at the name and use the tag incorrectly - you can see list of the posts &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/960536/questions-which-no-longer-have-the-given-tag-but-had-it-at-some-point?tagname=divisors&quot; rel=&quot;nofollow noreferrer&quot;&gt;where this tag was removed&lt;/a&gt;. (There is a &lt;a href=&quot;https://meta.mathoverflow.net/questions/194/help-improve-tagging/3596#3596&quot;&gt;proposal to rename the tag&lt;/a&gt; to make this distinction clearer.) Another example of a tag which is &lt;a href=&quot;https://chat.stackexchange.com/transcript/10243?m=47478797#47478797&quot;&gt;relatively often used incorrectly&lt;/a&gt; if &lt;a href=&quot;https://mathoverflow.net/questions/tagged/formal-proof&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;formal-proof&amp;#39;&quot; rel=&quot;tag&quot;&gt;formal-proof&lt;/a&gt;.

Think of MO and MSE as two journals aimed at a different readership. No journal I know of would appreciate it if rejected manuscripts from a companion journal would be transferred and published indiscriminately. MSE has its own guidelines and policies, and in many occasions the best we can do is to advise that a question might be suitable for MSE, if it is reformulated, sharpened, typed in LaTeX, and so on.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;2) Why not &quot;&lt;em&gt;Remove down-voting.&lt;/em&gt;&quot;&lt;br&gt;&#xA;I think that would be a good idea, but at present the down-votes are also used to signal to the software that this question requires attention in some way. Closed questions with down-votes are deleted after some time, closed questions with up-votes are not. There may well be a different way to achieve the same effect. On the meta site down-votes and up-votes have an altogether different meaning, they are used to signal whether one approves or not with a suggested change. A down-vote then simply means &quot;I am not in favour of this suggestion&quot;, while an up-vote says &quot;Yes, do implement this change&quot;. And in community-wiki &quot;big-list&quot; questions up-votes and down-votes are used to rank answers, which is why these votes are not counted towards your reputation.

Therefore it is recommended to enclose them within &lt;code&gt;\begingroup&lt;/code&gt; .. &lt;code&gt;\endgroup&lt;/code&gt;.

In such cases, the macros will no longer be rendered correctly. (Although they were working fine at the time of the posting.) The question is what to do with such posts and comments.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;I suppose that for posts the answer is simply to edit such posts - with the usual caveat that we should &lt;a href=&quot;https://meta.mathoverflow.net/questions/599/do-we-have-an-unofficial-quota-on-how-many-old-questions-one-should-bump-for-min&quot;&gt;avoid bumping many old posts at the same time&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;However, comments can only be edited by mods. (Possibly in some cases the poster would be able to delete comment and post a new one without disturbing the flow of the conversation - but if the comment is mid-conversation this would not be ideal.) Should we simply flag such comments and ask the moderators to edit?&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;I certainly do not want to cause flood of flags for the moderators. But I will assume that there will not be too many such comments, so most likely this will not be a major problem. But still it would be good to have confirmation whether flagging is the way to do.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;EDIT: Of course, there might be even cases when the comments cannot be fixed - in the cases when the edit (either expanding the macro or including the definition directly into the comment) would lead to number of characters above the allowed length of a comment.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;I will add at least on example illustrating this problem - &lt;a href=&quot;https://mathoverflow.net/questions/270836/is-deltadf-wedge-df-0-an-euler-lagrange-equation/271264#271264&quot;&gt;this answer&lt;/a&gt; (and a &lt;a href=&quot;http://web.archive.org/web/20190130072115/https://mathoverflow.net/questions/270836/is-deltadf-wedge-df-0-an-euler-lagrange-equation/&quot; rel=&quot;nofollow noreferrer&quot;&gt;snapshot from Wayback Machine&lt;/a&gt;).

I don't see how it's just a commentary or not even a partial answer.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In &lt;a href=&quot;https://meta.mathoverflow.net/questions/3973/why-is-this-answer-about-naming-bad#comment17676_3973&quot;&gt;this comment&lt;/a&gt;, Stanley Yao Xiao said:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;The answer almost entirely misses the point of the question, in my opinion. A specific critique is the claim that &quot;Fourier, Banach, or Peter-Weyl are meaningless&quot;, which is something that almost no mathematician would agree with.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;But I don't understand this point. Before and after this statement are the actually explanations. This is just a minor example, so if it's really wrong, you can simply ignore it.

I did visit the red herring page several times, but apparently I missed a lot of subtleties. It turns out that red herring names in mathematics are not simply wrong analogies, and coining new term may add more problems than fixing it like normal. I now understand and agree with the deletion.   &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Below is my draft to rewrite it. Hope to have your feedback (and your proofing).   &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Take the red herring name &lt;em&gt;noncommutative geometry&lt;/em&gt; as an example. Its correct form should be &lt;em&gt;not&lt;/em&gt; &lt;strong&gt;&lt;em&gt;necessarily&lt;/em&gt;&lt;/strong&gt; &lt;em&gt;commutative geometry&lt;/em&gt;  (or &lt;strong&gt;&lt;em&gt;possibly&lt;/em&gt;&lt;/strong&gt; &lt;em&gt;non-commutative geometry&lt;/em&gt;), but the adverbs are trimmed in a rush to explain an idea in which this concept is not the main focus. Because the main focus is not the concept itself, the concept is explained fleetingly, and this shortened form stabilizes in the circle.    &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In the insiders' minds, those subtleties have been implemented into the words, making them a variation of the original meaning. In other words, &lt;strong&gt;the word&lt;/strong&gt; &lt;strong&gt;&lt;em&gt;noncommutative&lt;/em&gt;&lt;/strong&gt; &lt;strong&gt;transforms into a polysemy.&lt;/strong&gt; It now has two senses:   &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The dominated sense: &lt;em&gt;truly noncommutative&lt;/em&gt;. This sense doesn't have subtlety (or we can say that it has the subtlety &lt;em&gt;truly&lt;/em&gt;)  &lt;/li&gt;&#xA;&lt;li&gt;The newfound sense: &lt;em&gt;not necessarily commutative, possibly non-commutative&lt;/em&gt;    &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;The problem is that one can only get this newfound sense after a period of learning. This is not the same in daily basis, in which the new subtleties can easily be explained after a small talk. So we have the dilemma:   &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Linguistically, this is a natural process and unavoidable  &lt;/li&gt;&#xA;&lt;li&gt;Cognitively, the required energy to deal with this linguistic process is not natural at all    &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;This applies well to my experience when learning math. For example, here is the formal definition of &quot;irreducible representation&quot; and my translation in the margin:   &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;strong&gt;Formal definition:&lt;/strong&gt; A representation U(G) on V is irreducible if there is no non-trivial invariant subspace V with respect to U(G). (Wu-Ki Tung, Definition 3.5)  &lt;/li&gt;&#xA;&lt;li&gt;&lt;strong&gt;My translation:&lt;/strong&gt; When a representation on a space is reduced to the point that only that space and {0} are its only two subspaces that can hold their vectors from being pulled out, then we have an irreducible representation.    &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;I do the translation by nesting definitions of each term in the definition, then rewriting it. I think this is the way to restore the &lt;em&gt;true intuition&lt;/em&gt; of irreducible representations before it is conceptualized. Notice how 4 times negation is used in the formal definition &lt;em&gt;(ir-, no, non-, in-),&lt;/em&gt; flipping the meaning back and forth. Logically, they can be canceled out, but perhaps linguistically the 4 negation version is more rigorous than the none one? I think, the formality of &lt;em&gt;logical connectives (and, or, not, if, iff)&lt;/em&gt; and &lt;em&gt;quantifiers (∀,∃)&lt;/em&gt; significantly trims down the subtleties that are necessary to understand formal definitions correctly: &lt;em&gt;impossible, necessary, unavoidable, indispensable, can't exist without, together with, there is no way, never again, etc.&lt;/em&gt;    &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think textbook authors may do a better service to their students if they start with this informal definition &lt;strong&gt;&lt;em&gt;before&lt;/em&gt;&lt;/strong&gt; getting to the formal one. Likewise, paper authors should emphasize the implicit assumptions in the term &lt;strong&gt;&lt;em&gt;before&lt;/em&gt;&lt;/strong&gt; using it, in case it is read by outsiders.    &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Having said that, even when both sides are aware of this, the &lt;strong&gt;execution&lt;/strong&gt;  to transfer the subtleties may face these obstacles:   &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;By definition, subtlety or &lt;a href=&quot;https://en.wikipedia.org/wiki/Tacit_knowledge&quot; rel=&quot;nofollow noreferrer&quot;&gt;tacit knowledge&lt;/a&gt; is extremely hard to recall. Even when the author is aware that they need to make it explicitly, they may not know where to start  &lt;/li&gt;&#xA;&lt;li&gt;Even if it is explicitly explained, the readers may overlook it, because they are overwhelmed with the information and just want to skim the paper. This makes them even more overwhelming    &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;My advice to deal with this:   &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The author needs to take every single note about their struggles when they learn/invent the concept, because after it becomes tacit knowledge, their notes are the only way to help them explain it to others  &lt;/li&gt;&#xA;&lt;li&gt;The student may need to equip the knowledge about mathematic polysemy so that (1) they have a strong motivation to carefully read the section explaining the subtleties, and (2) the author doesn't have to include a lecture about linguistics in a math book  &lt;/li&gt;&#xA;&lt;li&gt;The author should make the section about subtleties more overt and standing out, so that it will not be skipped when the paper is read &lt;a href=&quot;https://www.nngroup.com/articles/f-shaped-pattern-reading-web-content/&quot; rel=&quot;nofollow noreferrer&quot;&gt;F-shapedly&lt;/a&gt;   &lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;I cannot emphasize the last bullet enough. Maybe they should be put in a separate box with yellow background and the title &quot;Attention!&quot;. Maybe there should be a popup message with a checkbox &quot;I have read and agreed with all the subtleties&quot; before the continue button is clickable.

Then I made a mistake somewhere. Actually I am very interested in an example of a non-noetherian ring &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt; for which &lt;span class=&quot;math-container&quot;&gt;$\Spec A$&lt;/span&gt; is discrete. &lt;a href=&quot;https://mathoverflow.net/questions/283575/clarification-on-the-definition-of-a-smooth-affine-scheme-over-an-integral-domai#comment700244_283575&quot;&gt;Clarification on the definition of a smooth affine scheme over an integral domain&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;Thans, this really helps.

Ie, he said &quot;The induced maps &lt;span class=&quot;math-container&quot;&gt;$f^\sharp$&lt;/span&gt; on the stalks are just the local homomorphisms &lt;span class=&quot;math-container&quot;&gt;$\varphi_\mf{p}$&lt;/span&gt;&quot;, but these local homomorphisms are only defined for &lt;span class=&quot;math-container&quot;&gt;$\mf{p}\in\Spec B$&lt;/span&gt;, whereas they should be defined for all &lt;span class=&quot;math-container&quot;&gt;$\mf{q}\in\Spec A$&lt;/span&gt;, so it seemed like he was saying that as &lt;span class=&quot;math-container&quot;&gt;$\mf{p}$&lt;/span&gt; ranges over &lt;span class=&quot;math-container&quot;&gt;$\Spec B$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$f(\mf{p})$&lt;/span&gt; ranges over all of &lt;span class=&quot;math-container&quot;&gt;$\Spec A$&lt;/span&gt;, which is false.. &lt;a href=&quot;https://mathoverflow.net/questions/66753/morphisms-of-affine-schemes-question/66754#comment168961_66754&quot;&gt;morphisms of affine schemes question&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;span class=&quot;math-container&quot;&gt;$\newcommand{\fF}{\mathcal{F}}$&lt;/span&gt; Sorry to come back to this, but after rereading Hartshorne's definition of a morphism of locally ringed spaces, that even though as &lt;span class=&quot;math-container&quot;&gt;$V$&lt;/span&gt; ranges over all open nbhd's of &lt;span class=&quot;math-container&quot;&gt;$f(P)$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$f^{-1}(V)$&lt;/span&gt; ranges over a subset of the nbhd's of &lt;span class=&quot;math-container&quot;&gt;$P$&lt;/span&gt;, he still claims that &lt;span class=&quot;math-container&quot;&gt;$\lim_V \oO_X(f^{-1}(V)) = \oO_{X,P}$&lt;/span&gt;. (In your addendum to your original response, you said in general this limit, which you wrote as &lt;span class=&quot;math-container&quot;&gt;$(f_*\fF)_{f(x)}$&lt;/span&gt; is not ismorphic to &lt;span class=&quot;math-container&quot;&gt;$\fF_x$&lt;/span&gt;) &lt;a href=&quot;https://mathoverflow.net/questions/66753/morphisms-of-affine-schemes-question/66754#comment180895_66754&quot;&gt;morphisms of affine schemes question&lt;/a&gt; &lt;/li&gt;&#xA;&lt;li&gt;You're right, that was misleading. Let me restate the remark in a more useful form. First, &lt;span class=&quot;math-container&quot;&gt;$m$&lt;/span&gt;-equivalence is determined by constant-size neighbourhoods iff &lt;span class=&quot;math-container&quot;&gt;$(\Z,&amp;lt;,A,S,P)$&lt;/span&gt; has quantifier elimination. Now, for any set &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt;, the following are equivalent: (1) &lt;span class=&quot;math-container&quot;&gt;$(\Z,&amp;lt;,A,S,P)$&lt;/span&gt; has quantifier elimination, and no definable elements; (2) every finite string that occurs in &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt; occurs in all sufficintly long intervals. It's not immediately obvious that there are nonperiodic sets &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt; with this property, but one such is the Thue-Morse sequence, extended to &lt;span class=&quot;math-container&quot;&gt;$\Z$&lt;/span&gt; by putting &lt;span class=&quot;math-container&quot;&gt;$-n-1\in A$&lt;/span&gt; iff &lt;span class=&quot;math-container&quot;&gt;$n\in A$&lt;/span&gt;. So, .. &lt;a href=&quot;https://mathoverflow.net/questions/205985/is-there-a-leibnizian-model-with-no-definable-elements-in-a-finite-language/206058#comment511162_206058&quot;&gt;Is there a Leibnizian model with no definable elements, in a finite language?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;Can anyone give an elementary forcing-free proof that if we choose &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt; by coin flips, then almost surely &lt;span class=&quot;math-container&quot;&gt;$\langle\Z,&amp;lt;,A\rangle$&lt;/span&gt; has no definable elements?  &lt;a href=&quot;https://mathoverflow.net/questions/205985/is-there-a-leibnizian-model-with-no-definable-elements-in-a-finite-language/206058#comment510869_206058&quot;&gt;Is there a Leibnizian model with no definable elements, in a finite language?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;If CH holds, then &lt;span class=&quot;math-container&quot;&gt;$\R$&lt;/span&gt; is not &lt;span class=&quot;math-container&quot;&gt;$(\omega_2,\omega_3)$&lt;/span&gt;-compact, by the argument in your post: consider the theory of &lt;span class=&quot;math-container&quot;&gt;$\omega_2$&lt;/span&gt;-many distinct constants.

One improvement would be to ask for references or new pointers to the literature. The next would be to add some references to what is known (by authors distant from the poster, to avoid blatant promotional efforts; in the opposite direction, the poster can reference his own work on his own user page, and the question can state but not link to the user page).  If the question is part of a series, appropriate links to the series should be provided. (Appropriate in this context is deferred to another discussion.). Some more improvement would be to add motivation (what other problem gives rise to this question? What overarching study generates these questions in this fashion?).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Much as I am interested in prime gaps, I do not want to see a random prime gap question every day if there is no thought or perspective behind it, or something I can learn.  I would consider one every three to seven days, and if it were part of a series, I would prefer to see two or three parts of the series and a link off of MathOverflow to the rest of the series, especially when nothing essential is added by the other questions. (Essential is also deferred, but with each new MathOverflow question should come a slight shift in perspective, or a tie between perspectives, that makes the body of questions a learning experience rather than a series of chapter exercises.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If the question is known to enough specialists to be open, that should be stated (and a reference provided, if possible), but then the question should be a relevant reference request (&quot;Where can I read about applying Method X to Problem Y?&quot;) so that the perception is that the post contributes to the site rather than detracts.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For those who want to comment further on this issue, I recommend stating examples of well posted questions on MathOverflow, as well as (maybe old versions of) questions where some constructive improvements can be suggested.

Apart from the comments, make it clear also in the edit summary why you are making the edit.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;The first option is suitable only if your post will be long enough to varant a separate answer. (From the description in your question it seems that this is probably not the case here. Still, if this is at least a bit feasible, to me this seems as &lt;em&gt;better option than a larger edit to somebody else's post.&lt;/em&gt; So it is a judgement call: How big change does your edit actually make? Could this post be better as a separate answer?) One more benefit of posting is separate answer is that you are the owner of the post - so you have more control over the content of the post.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Let me still stress one thing - the final look of the answer should be &lt;strong&gt;the decision of the answerer&lt;/strong&gt;.&lt;sup&gt;1&lt;/sup&gt; It is natural to assume that editor acts in good faith and tries to make some improvements.  Minor edits (typos, forgotten dollar, some MathJax mistake, updating dead link) should be fairly uncontroversial. But if you want to make a larger edit, it is important to ask &lt;em&gt;whether the answerer agrees with it&lt;/em&gt;. In particular, don't to this if the answerer wasn't online for a long time&lt;sup&gt;2&lt;/sup&gt; and it is unlikely that they will be able to respond to your edit.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;From this viewpoint it is a minor advantage to you that all your edits have to be &lt;a href=&quot;https://meta.mathoverflow.net/tags/suggested-edits/info&quot;&gt;suggested edits&lt;/a&gt; (until you gain 2k reputation points) - which means that the answerer can reject the edit by one click in the suggested edit review.&lt;sup&gt;3&lt;/sup&gt; (For suggested edits, the edit summary is even more important, since you want the reviewers to see &lt;em&gt;why&lt;/em&gt; you want to edit the post.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;&lt;a href=&quot;https://en.wikipedia.org/wiki/TL;DR&quot; rel=&quot;nofollow noreferrer&quot;&gt;TL;DR&lt;/a&gt;:&lt;/strong&gt; Yes, this can be done - but only in some cases, so don't overuse it. Always ask whether the OP agrees with the edit. If the edit is long enough to make a separate answer, that might be a better option. In such case, make it clear in your answer that it is your elaboration of the details of another answer.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;A possible exception are &lt;a href=&quot;https://meta.mathoverflow.net/tags/community-wiki/info&quot;&gt;community wiki posts&lt;/a&gt;, which are intended for collaborative editing by the community.

Dorais♦ about this issue: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;&quot;&lt;a href=&quot;https://mathoverflow.net/questions/tagged/convexity&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;convexity&amp;#39;&quot; rel=&quot;tag&quot;&gt;convexity&lt;/a&gt; &lt;i&gt;is perplexing since it's almost a meta-tag. My preference would be to have these questions remapped to &lt;/i&gt;&lt;a href=&quot;https://mathoverflow.net/questions/tagged/convex-analysis&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;convex-analysis&amp;#39;&quot; rel=&quot;tag&quot;&gt;convex-analysis&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/tagged/convex-geometry&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;convex-geometry&amp;#39;&quot; rel=&quot;tag&quot;&gt;convex-geometry&lt;/a&gt;,&lt;i&gt; and similar. However, this seems very implausible at the moment.&quot;&lt;/i&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;The closest option above is the technically easy (2), solving the issue for future questions. If one wants to solve the issue for past questions, if one wants to completely delete &lt;a href=&quot;https://mathoverflow.net/questions/tagged/convexity&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;convexity&amp;#39;&quot; rel=&quot;tag&quot;&gt;convexity&lt;/a&gt;, one could imagine (if technically doable): remove &lt;a href=&quot;https://mathoverflow.net/questions/tagged/convexity&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;convexity&amp;#39;&quot; rel=&quot;tag&quot;&gt;convexity&lt;/a&gt; from every question with at least one of the other 2 tags; for those tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/convexity&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;convexity&amp;#39;&quot; rel=&quot;tag&quot;&gt;convexity&lt;/a&gt; and none of the other 2, remove &lt;a href=&quot;https://mathoverflow.net/questions/tagged/convexity&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;convexity&amp;#39;&quot; rel=&quot;tag&quot;&gt;convexity&lt;/a&gt; and add the other two (this will block for a few remaining ones for which there are already 5 tags but one can imagine these few can be dealt manually). But this can sound arbitrary, so just deprecating sounds enough, while users can then progressively manually delete past occurrences of deprecated &lt;a href=&quot;https://mathoverflow.net/questions/tagged/convexity&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;convexity&amp;#39;&quot; rel=&quot;tag&quot;&gt;convexity&lt;/a&gt;.&lt;/p&gt;&#xA;" OwnerUserId="14094" LastEditorUserId="14094" LastEditDate="2019-02-26T12:46:51.790" LastActivityDate="2019-02-27T20:25:57.673" Title="On convexity tags" Tags="|discussion|tags|tag-synonyms|tag-wikis|" AnswerCount="1" CommentCount="10" ContentLicense="CC BY-SA 4.0" />

So, I created a new tag &quot;small-uncountable-cardinal&quot; and tagged several my question with this new tag till realized that I forgot to add &quot;s&quot; at the end of cardinals. So, I tried to create a new (and more correct) tag &quot;small-uncountable-cardinals&quot;, but the system has blocked this attempt writing that a similar tag &quot;small-uncountable-cardinal&quot; exists already. So, I removed all tags &quot;small-uncountable-cardinal&quot; from my questions and now no question is tagged with &quot;small-uncountable-cardinal&quot;, but still this tag exists in the system and does not allow me to create a new tag &quot;small-uncountable-cardinals&quot;.

In the meantime I would like to ask the MO-community for opinion concerning the idea (basically of Martin Sleziak) to create this new tag &quot;small-uncountable-cardinals&quot; and retag the relevant questions (this last procedure is not accepted well by many MO users as it bumps up the retagged questions).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Search through MO by the phrase &quot;small uncountable cardinal&quot; yields 100 answers and I suggest that there are many questions which do not use this phrase but use small uncountable cardinals (like &lt;span class=&quot;math-container&quot;&gt;$\mathfrak b,\mathfrak p,\mathfrak d,\mathfrak c$&lt;/span&gt;, etc.).

I initially expressed that all this could be embedded into &lt;a href=&quot;https://mathoverflow.net/questions/tagged/continuum-hypothesis&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;continuum-hypothesis&amp;#39;&quot; rel=&quot;tag&quot;&gt;continuum-hypothesis&lt;/a&gt;, but several people have argued against this and I'm fine with those arguments. I'd like, anyway, that one additional benefit of the discussion would be to clarify the role/meaning of the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/infinite-combinatorics&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;infinite-combinatorics&amp;#39;&quot; rel=&quot;tag&quot;&gt;infinite-combinatorics&lt;/a&gt;; I don't think it's a separate issue as the intersection is significant.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Also, I'm against &lt;a href=&quot;https://mathoverflow.net/questions/tagged/cardinal-characteristics&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;cardinal-characteristics&amp;#39;&quot; rel=&quot;tag&quot;&gt;cardinal-characteristics&lt;/a&gt;, &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;because this will result in a misunderstanding of the its meaning (will be misused at many occasions), as it will be widely understood as &quot;properties of cardinals&quot;, and I don't think that properly understanding the meaning of a tag should be a privilege for those very specialists of the given subjects,&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;because &quot;characteristics&quot; seems to be used only by a proper subcommunity among the people dealing with such cardinals (I can substantiate this claim upon request), so a few questions naturally fitting with this tag will not be tagged so (or later by other people) — a typical such tag in another area seems to be &lt;a href=&quot;https://mathoverflow.net/questions/tagged/calculus-of-variations&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;calculus-of-variations&amp;#39;&quot; rel=&quot;tag&quot;&gt;calculus-of-variations&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;because the restriction to be &lt;span class=&quot;math-container&quot;&gt;$\le 2^{\aleph_0}$&lt;/span&gt; makes it too restrictive. Cardinals such as &lt;span class=&quot;math-container&quot;&gt;$(2^{\aleph_0})^+$&lt;/span&gt; or &lt;span class=&quot;math-container&quot;&gt;$2^{2^{\aleph_0}}$&lt;/span&gt; should be considered as small, as opposed to large cardinals. Small/large is not a completely defined boundary (roughly, large would be at least the smallest inaccessible) but I don't think it's not a problem, and it's even better than setting artificial boundary.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;because I can't detect any sensible argument making it better than &lt;a href=&quot;https://mathoverflow.net/questions/tagged/small-uncountable-cardinals&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;small-uncountable-cardinals&amp;#39;&quot; rel=&quot;tag&quot;&gt;small-uncountable-cardinals&lt;/a&gt;.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Edit (April 2020)&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Finally a majority led to create &lt;a href=&quot;https://mathoverflow.net/questions/tagged/cardinal-characteristics&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;cardinal-characteristics&amp;#39;&quot; rel=&quot;tag&quot;&gt;cardinal-characteristics&lt;/a&gt; about 13 months ago, with at this date 38 questions including 10 older ones that were retagged.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The use of this tag seems consistent and I'm finally convinced it was a good idea and that my reluctance was excessive.&lt;/p&gt;&#xA;" OwnerUserId="14094" LastEditorUserId="14094" LastEditDate="2020-04-27T12:56:25.510" LastActivityDate="2020-04-27T12:56:25.510" CommentCount="9" ContentLicense="CC BY-SA 4.0" />

I have encountered &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributivity in my encounters with ternary and &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary Laver tables (ternary Laver tables are really cool).&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;While the notion of &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributivity may seem a bit difficult to investigate, the hull of an &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributive algebra allows one to use binary self-distributivity to study &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributivity. Since binary self-distributivity is easier to grapple with than &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributivity, one should always take the hull of an &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributive algebra.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;This question is one of the more basic questions one can ask about the hull of &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributive algebras and about the nature of &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributivity.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;" OwnerUserId="22277" LastEditorUserId="22277" LastEditDate="2019-03-30T19:39:34.460" LastActivityDate="2019-03-30T19:39:34.460" CommentCount="2" CommunityOwnedDate="2019-03-30T03:08:47.303" ContentLicense="CC BY-SA 4.0" />

In particular, the free self-distributive algebra on one generator is contained in the variety generated by the classical Laver tables.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So I have extended the notion of the classical Laver table to a wide class of structures including the multigenic Laver tables. Furthermore, I have shown under strong large cardinal hypotheses that the free self-distributive algebra on countably many generators embeds into an inverse limit of multigenic Laver tables (the multigenic Laver tables are like the classical Laver tables but with multiple generators). In particular, the multigenic Laver tables generate the variety of all self-distributive algebras.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Now, the notion of self-distributivity can be generalized to &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary self-distributivity and these generalized notions of self-distributivity give one an abstract notion of what it means for an algebraic structure to have &amp;ldquo;inner endomorphisms.&amp;rdquo; The notion of a Laver table can also be generalized to the notion of a ternary and &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt;-ary Laver table. The only problem is that while the classical and multigenic Laver tables are always locally finite, the ternary Laver tables are in general not locally finite. The variety of ternary self-distributive algebras is probably generated by the ternary Laver tables, but since the ternary Laver tables are not locally finite, it is hard for me to predict whether the variety of self-distributive algebras is generated by its finite members.&lt;/p&gt;&#xA;" OwnerUserId="22277" LastEditorUserId="22277" LastEditDate="2019-03-31T17:12:00.547" LastActivityDate="2019-03-31T17:12:00.547" CommentCount="0" CommunityOwnedDate="2019-03-30T03:36:20.817" ContentLicense="CC BY-SA 4.0" />

Here are my thoughts.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The primary purpose of tags is to aid with search. As mathematicians, we have a tendency to think in terms of classification and taxonomy instead, but this is not the best way to think of tags and we should make an effort to stay away from this kind of thinking.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One specific rule is that tags should always be nouns for specific topics rather than adjectives, qualifiers and modifiers. To illustrate this, if I search for &quot;&lt;a href=&quot;https://scholar.google.com/scholar?q=topological&quot; rel=&quot;nofollow noreferrer&quot;&gt;topological&lt;/a&gt;&quot; on Google Scholar, the first two hits are about &quot;topological insulators&quot;, the next is about &quot;topological psychology&quot; and then I get recommended to search for an eclectic group of terms including &quot;topological superconductors&quot;, &quot;topological spaces&quot;, &quot;topological data analysis&quot;, &quot;topological spin&quot;, &quot;topological entropy&quot;, etc. This is not a useful search at all! On the other hand, the search for &quot;&lt;a href=&quot;https://scholar.google.com/scholar?q=topological+groups&quot; rel=&quot;nofollow noreferrer&quot;&gt;topological groups&lt;/a&gt;&quot; is spot on. Even searching for the very ambiguous noun &quot;&lt;a href=&quot;https://scholar.google.com/scholar?q=groups&quot; rel=&quot;nofollow noreferrer&quot;&gt;groups&lt;/a&gt;&quot; is not as eclectic as the adjective &quot;topological&quot; since it homes in on a handful of specific topics commonly called &quot;groups&quot; such as &quot;minority groups&quot; and &quot;ethnic groups&quot;, as well as the mathematical topic.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The proposal for &quot;&lt;a href=&quot;https://mathoverflow.net/questions/tagged/small-uncountable-cardinals&quot;&gt;small-uncountable-cardinals&lt;/a&gt;&quot; is very close to a modifier. It definitely sounds like one and the current tag description seems to suggest using it as a modifier. That said, this is an interesting case since there is an underlying specific topic here. For comparison, the tag &quot;&lt;a href=&quot;https://mathoverflow.net/questions/tagged/large-cardinals&quot;&gt;large-cardinals&lt;/a&gt;&quot; sounds like a modifier but it is in fact a very specific topic and the usage of the tag is consistent with that meaning.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;To summarize, there is a specific topic that could be described as &quot;small-uncountable-cardinals&quot;, but this is not a good name for that topic since it sounds like a modifier and there is no recognizable topic commonly called &quot;small uncountable cardinals&quot;. I'm surprised the tag &quot;&lt;a href=&quot;https://mathoverflow.net/questions/tagged/cardinal-characteristics&quot;&gt;cardinal-characteristics&lt;/a&gt;&quot; doesn't exist already since that is a specific topic with two chapters in the &lt;a href=&quot;https://www.springer.com/us/book/9781402048432&quot; rel=&quot;nofollow noreferrer&quot;&gt;Handbook of Set Theory&lt;/a&gt;. This is perhaps too specific for all that &quot;small uncountable cardinals&quot; could mean, but this is probably the way to go: have two or three more specialized tags that together capture the topic of &quot;small uncountable cardinals&quot;.

Why do we have such a limitation? Why only 3 bounties? &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have asked some questions on this site that did not receive an answer. I understand that nobody owes me an answer but I want to maximize my chances, so to speak. Being able to post only 3 bounties seriously limits the rate at which these questions are going to get processed (each bounty lasts a week). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I guess one possible answer is that you do not want too many bounties (which would dilute the distinction between a bountied and an unbountied question). But then, I am paying hard MO points, honestly earned by posting content the community appreciates. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you think that the current minimum amount of rep investment required to start a bounty is too little, fine, I get you. Let us increase the number of rep points per each consecutive bounty (e.g. +25/bounty). I mean, this is a free country, if a person wants a service and is willing to pay, why not offer this service? If you do not provide it, I might just take my MO points elsewhere. &lt;/p&gt;&#xA;" OwnerDisplayName="user137767" LastActivityDate="2019-04-16T20:52:58.123" Title="Remove the upper bound on the number of bounties a single user can have at any moment" Tags="|feature-request|bounty|" AnswerCount="1" CommentCount="6" ContentLicense="CC BY-SA 4.0" />

Very little would change if users were able to have an unlimited number of bounties at once. I personally do not have any strong feelings for or against increasing the bounty limit, but since it is not a good idea to change the way aspects of this site work very often for minor issues, I would want to keep the 3 bounty limit the way it is. Here are reasons why I think that having unlimited bounties will not improve MO very much.&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;If one were to have 3 bounties simultaneously at all times, then these bounties would cost the user 150*52=7800 points a year. Very few users can afford to spend 7800 points on bounties a year. For example, only 8 or so MO users have obtained points at at least this rate from January 1,2019 to April 16, 2019. For this reason, I would consider the three bounty limit to be quite high. This 7800 points a year cost is the cost if one spends the bare minimum of 50 points per bounty. If one were to spend the maximum of 500 points instead per bounty, then one would need to spend at 78000 a year which exceeds the 200 daily reputation increase limit.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The MO users like to hodl (hodl is a term used in the cryptocurrency sector which means to &amp;ldquo;hold on to dear life&amp;rdquo; to Bitcoins or other cryptocurrencies) onto their MO reputation coins rather than spend them on bounties. In practice, MO users typically do not have or want multiple bounty questions up at once.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;It seems like it would be a better strategy to promoting questions using bounties would be to space the bounties over a period of time rather than give several bounties at once. For example, instead of having 4 bounties at once for a week, it would probably be better to give each of these four questions a bounty for one week out of the month so that at no time the user has no more than one bounty up.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The three bounty limit is a slight protection against a user quickly getting rid of all of the reputation at one instance perhaps when deciding to leave MO.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Most MO users do not ask questions at a rate where they would be able to give three bounties a week for each of their questions. Furthermore, most of the high reputation MO users seem to be more interested in answering MO questions than they are in asking them. Therefore, the people who can actually afford to spend their reputation on 3 bounties a week seem like the ones who would be less interested in giving bounties. It seems like the users who actually do spend their points on bounties are the low reputation users who cannot afford to spend their reputation on more than 3 bounties a week. In any case, there does not seem to be any demographic of users who would be willing to spend more than 3 bounties a week.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;" OwnerUserId="22277" LastActivityDate="2019-04-16T20:52:58.123" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

I do not believe that these downvotes have any legitimacy since I have recently been receiving many downvotes and all of these downvotes for the questions that I have asked are without any explanation.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In this question, I proposed the notion of a reversible variety since I noticed that several varieties including the varieties of groups, racks, quandles, and other varieties have a flavor of reversibility in the sense that the fundamental operations are simply projections of bijective functions which are composed of these fundamental operations. I think of the notion of a reversible variety as being a generalization of the notion of a group.

You ask whether there is research on &quot;in which mathematical universes does Grothendieck's approach succeed&quot;, and we are left with the rather formidable tasks of unpacking the terms &quot;mathematical universes&quot;, &quot;Grothendieck's approach&quot;, and &quot;succeed&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;When people asked for clarification in the comments, we see that the definition of &quot;mathematical universes&quot; is unclear, but it seems you are partial to considering arithmetic systems too weak to prove Godel's incompleteness theorem.  Perhaps you would have better luck considering nonstandard models that can actually prove incompleteness.  Your definition of &quot;succeed&quot; seems to be &quot;thousands of pages of monographs&quot;, which is a bit stringent for work on hypothetical worlds.  Finally, &quot;Grothendieck's approach&quot; has been reduced to something like being careful when defining things, and this hardly seems to be unique to Grothendieck.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;One point I'd like to emphasize is that when you ask a question where an answer might require non-trivial effort, you should take care to remove as much ambiguity as you reasonably can, and you should at least give the impression that you will take serious answers seriously.

This is the main function of conferences so it would be great to have an online forum that serves this same purpose especially for early researchers who cannot afford going to all the different conferences.&lt;/li&gt;&#xA;&lt;li&gt;This should be a separate site from MO because many of these posts will not be answerable in the short term. Otherwise, if we start adding such posts in MO (eg. under the tag &quot;open problems&quot;), they will quickly crowd the usual MO posts which can be answered in the short term. &lt;/li&gt;&#xA;&lt;li&gt;Conversely the answerable MO posts under the tag &quot;open problems&quot; will distract from the database questions.

However, the site will quickly become crowded as subproblems are being added. &lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;I think it will have a great longevity due to the good robustness of SE sites. Most professors are posting their research problems in their individual websites, which cannot be edited by others and worse might get taken down after the professor retires.&lt;/li&gt;&#xA;&lt;li&gt;It will complement the OpenGarden and the OpenProblems projects. The SE version will serve as a large database for the research problems out there and their corresponding approaches. The OpenGarden will be the more monitored and formal version to avoid the ambiguities from the SE version. The SE version will serve as the place for the raw input of research problems and approaches.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&#xA;&lt;p&gt;We will greatly appreciate any comments.

(Hat tip to Martin Sleziak for a link to an excellent starting point.)  For ease of reference: there is no exact policy on MathOverflow considering answering off-topic questions.  I think a primary reason is that there is some disagreement on what is off-topic.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Even when there is much agreement (e.g. spam, or questions from pre-university math courses), there is disagreement as to how such questions should be treated. In my view, one camp is content with the current level of membership and participation of that membership (level referring both to frequency of posts and degree of technicality/specialization of content), and thus is less inclusive, while other camps are more inclusive, and have a higher level of tolerance for responding to off-topic questions.  I belong to this camp because I believe that sustained effort is needed to refresh the population and contribute the material that satisfies me and satisfies the other camp.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;My suggestion is to use a comment (in rare cases, an answer, cf 328312 for an example of mine) to indicate that a question is off topic and then (let someone else) vote to close.

Since then, they've proliferated like hydra heads.  They mostly focus on a single theme (i.e. the purely topological  properties of schemes), and the user continues to avoid engagement with responses of all sorts, including those seeking clarification.

This type of attention-drawing is based on deceit, is thoroughly obnoxious, and is inherently problematic. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think the behavior promised in this user profile &lt;a href=&quot;https://mathoverflow.net/users/141500/human-path?tab=profile&quot;&gt;https://mathoverflow.net/users/141500/human-path?tab=profile&lt;/a&gt; also qualifies as problematic: &lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;The Six Paths of Pain are controlled by Nagato. The Six Paths of Pain do not answer, upvote, comment on each other's posts. The Six Paths of Pain award bounties on each other's posts. &lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Judging from this post, it seems that Community Management agrees this behavior is not cool: &lt;a href=&quot;https://meta.stackexchange.com/questions/37096/who-or-what-is-this-so-user&quot;&gt;Who or what is this SO user?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Still other problematic aspects include opening new accounts in response to other accounts being closed. In one case relevant here, an account named &quot;mika&quot; was (re)created after a same-named account was deleted, with the user openly saying so. Deletion can mean one of several things. One is that Community Management or site moderators have decided that the user is no longer welcome, in which case the user opening a new account is explicitly in violation of community moderation. Another is that the user is self-deleting the account voluntarily. But in this case as well, coming back again in a new form flouts the norms of this site, especially by enabling the user thereby to evade community moderation and policing. This is akin to question repetition, as when a user deletes his post and then asks again. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Still another problem -- more of a judgment call but nonetheless real -- is trollish behavior (sealioning, etc.). In my opinion, and in the opinion of other community members, there have been a few instances of that in the current circumstances, both at meta and at main. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;In such cases, when the behavior becomes problematic and repeatedly so, we may have to clamp down a little harder. (Many of you will remember one or a very small band of users engaged in shenanigans a few years ago, with the main perpetrator now permanently banned from SE.) I don't have a problem per se with a user controlling a number of accounts -- as long as site policies and guidelines are not being flouted and deceit is not taking place. Otherwise I have a big problem with that. &lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;I guess I'll begin documenting here suspicious events as I see them. For those users who seem puzzled about my linking certain posts on MO Main to this discussion, I repeat: forensic analysis strongly suggests to me that all of the many accounts listed above are associated with each other, and I think the community should be aware of events that are occurring within this circle. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;For those with 10k+ reputation: the (unregistered) user &quot;Curious girl&quot; asks a spam question &lt;a href=&quot;https://mathoverflow.net/questions/333692/big-topos-guys-why&quot;&gt;https://mathoverflow.net/questions/333692/big-topos-guys-why&lt;/a&gt; which makes a crude joke about genital size. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;User &quot;cardinal&quot; &lt;a href=&quot;https://mathoverflow.net/users/74900/cardinal&quot;&gt;https://mathoverflow.net/users/74900/cardinal&lt;/a&gt; has the following recent reputation events &lt;a href=&quot;https://mathoverflow.net/users/74900/cardinal?tab=reputation&quot;&gt;https://mathoverflow.net/users/74900/cardinal?tab=reputation&lt;/a&gt;: yesterday there are 5 upvotes in the same minute 20:14, and 4 upvotes in the same minute 16:26. Today (June 11) there is a slew of upvotes all within a short span of time. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A number of accounts in this circle that are offering bounties follow a characteristic pattern where coincident with offering bounties, the account is scheduled for deletion. This will continue until past the time of deletion, and then the deletion will be rescinded. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;A new version of Asura Path became a member today &lt;a href=&quot;https://mathoverflow.net/users/141752/asura-path?tab=profile&quot;&gt;https://mathoverflow.net/users/141752/asura-path?tab=profile&lt;/a&gt;, after a same-named account was self-deleted.

After 6 spam flags, the post is deleted. In addition to being deleted, even for users who can &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;see the deleted posts&lt;/a&gt;, the content of the post is hidden - although they can still access the revision history. The same thing happens after a total of 6 flags that are either &quot;spam&quot;, or &quot;rude or abusive&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;A detailed network-wide FAQ about spam can be found on Meta Stack Exchange: &lt;a href=&quot;https://meta.stackexchange.com/q/58032&quot;&gt;What are the “spam” and “rude or abusive” (offensive) flags, and how do they work?&lt;/a&gt; That link, together with some additional links, can be found in the spam tag-info on &lt;a href=&quot;https://meta.mathoverflow.net/tags/spam/info&quot;&gt;this meta&lt;/a&gt;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Some additional remarks:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Spam flags should be only used for posts that really contain spam. (A post is considered spam only if it advertises a product, service, or similar and is either or both unsolicited or lacks disclosure that the user is affiliated with the product/company/linked site/etc. This is elaborated in more detail in the &lt;a href=&quot;https://meta.stackexchange.com/q/58032&quot;&gt;network-wide FAQ&lt;/a&gt;.)&lt;/li&gt;&#xA;&lt;li&gt;A spam flag automatically adds a downvote, so it's not necessary to downvote the post in addition to that. See also: &lt;a href=&quot;https://meta.stackexchange.com/q/193916&quot;&gt;Why shouldn't I downvote spam that I've already flagged?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;Also voting to close (or to delete) is not really necessary - it is likely that 6 users with 15 reputation points get to the post quicker than 5 users who have enough reputation to cast close votes. Of course, this assumes that the users know how to handle spam posts. Voting to close, when done &lt;em&gt;in addition to flagging as spam&lt;/em&gt; doesn't cause any harm, other than spending one of your close-votes. It is better not to vote to delete. If the post is deleted by votes rather than by spam flags, it's good to notify moderators about this. For more details, see: &lt;a href=&quot;https://meta.stackexchange.com/q/283948&quot;&gt;Should we vote to delete spam posts?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;Editing the spam content out &lt;em&gt;can be counterproductive&lt;/em&gt; - since other users who see the same post might not realize the it is spam. It's also possible that the spam post will be seen as a real post and end up giving the spammer significant reputation. On one Stack Exchange site, there's even been one edited spam question from a repeat spammer that got answers and made it onto the Hot Network Questions list. The spammer getting reputation makes it significantly harder to deal with their subsequent spam, as many of the automated checks for spam are bypassed for users with even a moderate amount of reputation. See also: &lt;a href=&quot;https://meta.stackexchange.com/q/110030&quot;&gt;Should spam posts be edited?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;So, basically, it can be said that once you've flagged the post, there is not much more to be done on your side. One possible exception is in cases when it might be unclear that the post is actually spam. (For example, if the post otherwise looks reasonable - perhaps because the content was copied from somewhere - but a punctuation mark or one word contains spam link.) In such cases, it might be useful to comment - in order to make spam more obvious to other users. If it doesn't look like spam just by glancing at it, you can use a custom moderator flag to explain to the moderators why it's spam.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Possibly - if you think that the spam might not be deleted quickly enough&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;You might leave a comment explaining to other users who see the same post what they should do. For example, you could link to this post in your comment.&lt;/li&gt;&#xA;&lt;li&gt;Theoretically, you can even mention the post in chat to attract the attention of other users.&lt;/li&gt;&#xA;&lt;li&gt;You are always welcome to report spam, or posts you think might be spam, in &lt;a href=&quot;https://chat.stackexchange.com/rooms/11540/charcoal-hq&quot;&gt;Charcoal HQ&lt;/a&gt;. &lt;a href=&quot;https://charcoal-se.org/#get-involved&quot; rel=&quot;nofollow noreferrer&quot;&gt;Charcoal&lt;/a&gt; is a project with the specific goal to help with detecting spam in the Stack Exchange Network.

If you got discouraged by the phrase &quot;This question does not appear to be about research level mathematics&quot; on your &quot;extension of primes&quot; question, don't pay any attention to it because it is just the result of having to do a multiple choice in which no standard option applies and being too lazy to formulate and type the real reason, which is that solving it will require far more knowledge about prime distribution than the humanity currently possesses and there are several well-known problems in the same venue already starting with the twin prime conjecture (which is &quot;almost solved&quot; now). &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I'm in the camp that thinks that currently there are way too many people who ask questions and make conjectures and way too few who provide answers, so if it were my will, I would introduce a temporary quota of &lt;span class=&quot;math-container&quot;&gt;$2/3$&lt;/span&gt; questions one would be allowed to ask per each one he answered for professional mathematicians (not on MO, but globally) until our Augean stables are cleaned a bit. However even I realize that, once a clear and non-trivial question is asked, it cannot be unasked, and declaring it a &quot;bad question&quot; or &quot;not interesting question&quot; or anything else like that tells more about the declarer than about the question itself.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, don't worry: the hard elementary questions won't be lost.

Some of the new features are the limit on the number of hot questions from a single site, or limit on how long a question can be in the HNQ list. For more details, see the announcement on Meta Stack Exchange: &lt;a href=&quot;https://meta.stackexchange.com/q/325060&quot;&gt;Updating the Hot Network Questions List - now with a bit more network and a little less “hotness”!&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;One of the new features was that moderators can remove the question from the HNQ list. I will quote a part of the linked announcement:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;We're putting the power in the hands of our moderators to remove questions that don't set a good example for their sites. I recommend each site have a meta discussion with guidance for moderators about when - if ever - a question should be removed.&lt;/p&gt;&#xA;&lt;p&gt;Once a moderator excludes a question, it can't be selected again, so don't think of this as a temporary &amp;quot;hide this question&amp;quot; option. In general, we recommend that you exclude questions that attract negative attention to your sites, that is, questions that are controversial, start large amounts of debate or arguments or even edit wars.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;For example, you can see that many questions have been removed from the HNQ list by moderators &lt;a href=&quot;https://data.stackexchange.com/math/query/1013246/questions-removed-from-hnq-by-mods?num=500&quot; rel=&quot;nofollow noreferrer&quot;&gt;on Mathematics Stack Exchange&lt;/a&gt;. As far as I can tell, this hasn't happened for &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1013246/questions-removed-from-hnq-by-mods?num=500&quot; rel=&quot;nofollow noreferrer&quot;&gt;any questions on MathOverflow&lt;/a&gt; yet.&lt;/p&gt;&#xA;&lt;p&gt;If you are curious to see what the recent HNQs from MathOverflow look like, you can check the Hot Network Questions chatroom, which &lt;a href=&quot;https://chat.stackexchange.com/users/-949/math-overflow?tab=recent&quot;&gt;has a feed&lt;/a&gt; with the HNQs. (Or you can simply &lt;a href=&quot;https://chat.stackexchange.com/search?q=mathoverflow.net&amp;amp;room=89485&quot;&gt;search for mathoverflow.net&lt;/a&gt; in that room. There is also the room called &lt;a href=&quot;https://chat.stackexchange.com/transcript/70737&quot;&gt;Listing bounties and HNQs&lt;/a&gt;.&lt;sup&gt;1&lt;/sup&gt;) Alternatively, you can use &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;Data Explorer (SEDE)&lt;/a&gt;, for example, &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/revision/1069120/1321118/recent-hot-network-questions?num=500&quot; rel=&quot;nofollow noreferrer&quot;&gt;this query&lt;/a&gt;. (Keep in mind that the data in SEDE are only updated once a week, so you won't see the questions which entered the HNQ since the last Sunday in this way.)&lt;sup&gt;2&lt;/sup&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Questions.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;Should in some cases MO questions be removed from the HNQ list? What types of questions should be treated this way?&lt;/li&gt;&#xA;&lt;li&gt;If a user spots a MathOverflow question in the HNQ list and they think that it does not belong there, what is the proper action they should take? Is flagging the question for moderators' attention and including a custom explanation a reasonable course of action?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;&lt;strong&gt;Some additional remarks&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;To some extent, hot questions &amp;quot;represent&amp;quot; MathOverflow to users on other sites in the network, since those are the question that they see unless they visit it regularly. So depending on which questions are chosen for the HNQ, they might give users coming here after clicking on them a wrong impression about what MO is supposed to be. You can see that there are questions which &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/revision/1069116/1321114/questions-which-are-closed-and-were-in-the-hnq&quot; rel=&quot;nofollow noreferrer&quot;&gt;are closed&lt;/a&gt; or &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/revision/1069117/1321115/questions-which-were-in-hnq-and-were-closed-at-some-point&quot; rel=&quot;nofollow noreferrer&quot;&gt;were closed at some point&lt;/a&gt; and yet they were in the HNQ list - if a question got closed, then it's perhaps not the best representative for the site.&lt;/li&gt;&#xA;&lt;li&gt;It seems that there is not that much traffic from the HNQ list compared to total visits of MO: &lt;a href=&quot;https://meta.mathoverflow.net/q/1388&quot;&gt;Traffic from the list of hot network questions&lt;/a&gt;. In the past discussions about &lt;a href=&quot;https://meta.mathoverflow.net/questions/1350/featured-mo-questions-on-the-hot-list-what-benefits-if-any-do-these-bring&quot;&gt;benefits&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/questions/1305/measures-to-separate-math-overflow-from-the-rest-of-the-stack-exchange-network&quot;&gt;possible&lt;/a&gt; &lt;a href=&quot;https://meta.mathoverflow.net/questions/435/the-association-bonus&quot;&gt;problems&lt;/a&gt; with hot questions, it seems that one issue that many users raised was the fact that they might cause some votes from users with insufficient knowledge of the problem at hand. For this reason, I'll mention once again this feature request: &lt;a href=&quot;https://meta.stackexchange.com/q/238420&quot;&gt;Prevent questions on Hot List from being upvoted by casual visitors (only rep is from association bonus)&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;In a way, regular users can also remove a post from HNQ simply by editing the title - since questions containing MathJax in the title &lt;a href=&quot;https://meta.stackexchange.com/questions/237475/are-the-questions-with-tex-markup-in-titles-excluded-from-hot-network-questions&quot;&gt;are not allowed into the HNQ list&lt;/a&gt;. However, there might be some cases when a more natural title would be without any mathematical formulas. And this could possibly lead in some cases to editing wars. So in cases where removal of a question from HNQ is really needed, I would consider an intervention by a moderator as a cleaner solution (unless the title with MathJax is clearly better and more descriptive). &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223619/questions-which-were-in-hnq-and-have-in-the-title&quot; rel=&quot;nofollow noreferrer&quot;&gt;This SEDE query&lt;/a&gt; lists questions which were in the HNQ list and MathJax was added to the title later - however, we do not know whether removal from the HNQ was the motivation the edit (at least partially).&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;hr&gt; &#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;This room contains only questions from MO - however, both featured questions and HNQs are posted there. Since April 15 the HNQs can be easily distinguished - those are the questions posted by the feed called &lt;a href=&quot;https://chat.stackexchange.com/users/-1078/hnq-mo?tab=recent&quot;&gt;HNQ MO&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;I should explicitly mention that entering HNQ is recorded in the revision history/timeline/SEDE &lt;a href=&quot;https://meta.stackexchange.com/questions/324641/now-you-can-know-if-a-question-really-hit-the-hnq&quot;&gt;only since the end of February 2019&lt;/a&gt;, so you won't find information about older questions.

Presumably he does not have access to a library or other resource which has a subscription. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I feel like this is a somewhat contentious issue. Indeed, there is now a movement among some scientists that are rallying against the existence of paywalls. For example, the University of California system recently dropped their subscription to Elsevier journals: &lt;a href=&quot;https://www.vox.com/science-and-health/2019/3/1/18245235/university-of-california-elsevier-subscription-open-access&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://www.vox.com/science-and-health/2019/3/1/18245235/university-of-california-elsevier-subscription-open-access&lt;/a&gt;. Long before that, Tim Gowers and several others started an initiative specifically targeting Elsevier, rallying mathematicians to sign a declaration that they will not submit papers to Elsevier journals nor do any service (editor/refereeing) for them. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Opinions aside, what is the MO stance on assisting people get papers that appear to only exist behind a paywall?&lt;/p&gt;&#xA;" OwnerUserId="10898" LastEditorUserId="8250" LastEditDate="2019-06-28T03:00:05.050" LastActivityDate="2019-06-28T03:51:21.287" Title="Does MathOverflow help people get past paywalls?"

However, I think the community should have a stance on helping researchers.

I will&#xA;need a head count (or I will put you down as 1)&#xA;and a shipping address. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I hope to update later with details of what swag is&#xA;available.  Sending an early request with swag type now&#xA;does not hurt.  (Sending a late request also doesn't&#xA;hurt, but it might not be filled.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you offer to be a host/admin, mail me with a&#xA;projected head count.

Also initiatives such as Plan-S in Europe have not really contributed in this direction. There seem to be larger and larger masses of papers submitted to classical peer-reviewed journals and most of them are congested.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;My opinion is that such a system (posting abstracts of linked arxiv articles on MO) and asking for reviews would be a big relief to the system. However I think that the main problem would be of finding a way to include anonymized (sponsored) reviews (which is a very important aspect of the peer-review system). Maybe one could have a group of moderators acting as editors and they would be responsible for searching/receiving a review (which could also come from outside the MO community) and posting it as an answer.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I also think that math annotations and reviews are two different things. I would first stick to the review context, where answers are only allowed to be classical reviews and comments would only concern specific (technical) questions. This would imply some sort of &quot;strong&quot; moderation from the community, but I think that the success of MO has shown that this is possible (I myself would be prepared to be involved in sections related to my subjects - for sectioning we could for example use MSC classifications).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Moreover, I do not think that MO rep of the user (author) who submits a paper for review is going to be relevant in the hiring process (or at least as relevant as RG's score or H-index etc. is), but I somehow envision this MO section as becoming a new type of &quot;journal&quot;, which assigns reputation to an article. Having a linked paper with an &quot;accepted review&quot; and a good number of upvotes could be considered as having a paper with a substantial impact.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you ask me, I think we should just do it and see how it evolves. Otherwise discussions will just continue until the people don't have anymore time to invest.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;EDIT: I have posted an example review here &#xA;&lt;a href=&quot;https://meta.mathoverflow.net/q/4301/40644&quot;&gt;(Example) Peer-Review request: Independent, Negative, Canonically Turing Arrows of Equations and Problems in Applied Formal PDE&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Hopefully I have not broken around 1000 forum rules.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;EDIT2: I have deleted the above post and will give a try with Gerhard Paseman's article he was kind enough to &quot;volunteer it&quot; for a community review. Since I regard the current problems of the peer-reviewing system as dire, it would be great if the downvoters also comment on the subject. The main goal is to find a way to improve the system-this is a problem of the community and it has to be solved within it.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;EDIT3: Gerhard Paseman's article has been posted: &lt;a href=&quot;https://mathoverflow.net/q/336355/40644&quot;&gt;Peer-Review request: Updating an upper bound of Erik Westzynthius&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;EDIT4: Sadly the experiment ended quickly.

There's a very common trope in math where people analogize math to an attractive woman often explicitly in a sexual way.  I've seen this happen in talks.  I once saw it happen in a talk where the person illustrated the point with a photo.  This is all really deeply inappropriate and people need to stop.  The analogy in that joke only works if the listener thinks of themself as staring at the woman, and completely fails if the listener thinks of themselves as the one wearing the skirt.  And it's not just a one-off joke, it's a common trope that's really problematic and puts women graduate students in a terrible position when people make this kind of analogy in public.  Having it here, especially with it highly upvoted, especially with people writing defenses of it, especially with it coming from a famous mathematician (of sorts), is continuing the culture that says that it's ok to make analogies between mathematics and attractive women, and that's not ok.&lt;/p&gt;&#xA;" OwnerUserId="22" LastActivityDate="2019-08-03T19:52:31.173" CommentCount="20" ContentLicense="CC BY-SA 4.0" />

(The first, at least to my knowledge, was the deletion of a question about &quot;what image epitomizes mathematics to you&quot; after &lt;a href=&quot;https://en.wikipedia.org/wiki/The_Scream&quot; rel=&quot;nofollow noreferrer&quot;&gt;this image&lt;/a&gt; became the highest upvoted answer.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are good points to be made against having threads like this on MO; I agree with what seems to be the consensus about them, which is that these are bad questions, relics of a bygone age when MO was still figuring out what it wanted to be. The march of science would not be impeded if they had never been asked.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, deleting them, in my opinion, requires better reasons than not starting them in the first place. Worse yet is my impression that the deletions are motivated not by pondering what would make MO a better forum but by an (implicit, yet rather transparent) desire to appear maximally professional, polite and smooth to the outside world. And this is not a great goal to set -- even if I assume that outside appearance is nearly as important a goal as inside usefulness (full disclosure: I don't), I believe it is too deceptive a light to steer our ship towards. Consider the likely effects of the deletion of the jokes thread: The jokes thread is no longer publicly visible. But &lt;a href=&quot;https://meta.mathoverflow.net/questions/4307/should-these-sexually-suggestive-jokes-be-kept-or-deleted?cb=1&quot;&gt;the question debating the appropriateness of the sexual jokes therein&lt;/a&gt; remains visible (it's on meta, so there is far less grounds on which it could be deleted). Everyone who cannot see deleted threads is likely to conclude, on the basis of their priors and political leanings, that&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;either some really creepy jokes have stood undisputed on MathOverflow since 2009,&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;or MathOverflow has succumbed to outside pressure on a current moral panic and deleted a whole thread based on a few risqué posts.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Either of these paints MO and its governance in a worse light than the thread itself. Meanwhile, no one has stepped in to claim any actual damage from any of the deleted answers. The main forces behind the deletion seem to be &quot;these jokes are unprofessional&quot; and &quot;no one cares for this thread anyway&quot;. But the slope is slippery, since we have now set an expectation that even theoretical concerns about unprofessional-looking posts will be met with deletion. Next time it may well hit closer to home, and eventually we'll &lt;strong&gt;have&lt;/strong&gt; to respond with &quot;thanks for your concerns, but our core community believes them not strong enough to delete useful content&quot;. The later this happens, the bigger the resulting shitstorm and outrage. In some circles, it is best to never become a fellow traveler, lest you become a traitor once your paths split.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;What I've said before is not particularly novel and I expect disagreements to be at where to place our red lines rather than whether there should be any. But with too many different red lines, we'll eventually see the window of conversation narrow even further, since it is easier to get a question deleted than to get it undeleted (math.stackexchange is currently having &lt;a href=&quot;https://math.meta.stackexchange.com/questions/30163/can-we-please-stop-closing-and-deleting-old-posts-with-answers&quot;&gt;a similar problem&lt;/a&gt; for other reasons). Thus, in the interest of common ground, here are some &lt;strong&gt;specific suggestions:&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Content that appears to be useful or interesting to a reasonable number of mathematicians (witnessed, e.g., by 10 upvotes, by 5 upvotes and appreciative comments from established users, or by citations from published literature) is not to be deleted barring very grave and specific reasons (e.g., passwords being leaked).&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Full thread deletion is to be reserved for threads with no redeeming value whatsoever. Answer deletion is to be reserved for answers that are so bad or unredeemable that downvotes and comments of disapproval don't help.&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Vague notions like &quot;professionalism&quot;, &quot;appropriateness&quot; and &quot;inclusivity&quot; are not to inform moderation decisions until made precise with more specific arguments. Non-CW posts are to be understood, first and foremost, as statements by their original authors, not as manifestations of the &quot;spirit of MO&quot; whatever it might be; they are furthermore not understood to be targeted at any specific reader unless visibly declared to be targeted.

As one of a few prominent older light-hearted threads, &lt;strong&gt;it helped make MO an entertaining and enjoyable place&lt;/strong&gt; — like the departmental lounge, where you talk maths but also relax a bit.  If such questions are lost, it comes to feel more like a research-level equivalent of a TA session or a lecturer’s office hours: useful, but less entertaining and enjoyable, both for new and established users.   And the goal of usefulness is not well served if users are less attracted to the site, or less inclined to return, because it’s a less enjoyable place than it was before.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So far I’ve seen two arguments given &lt;em&gt;for&lt;/em&gt; the deletion, in &lt;a href=&quot;https://meta.mathoverflow.net/a/4310/2273&quot;&gt;Noah Snyder’s answer on the thread about the sexist jokes&lt;/a&gt; and the comments thereon.  The first argument (given by Noah) is that it’s off-topic by the current site standards.  That’s a reasonable point, but it seemed pretty well addressed by having the question closed and locked, and with a clear notice explaining its historical status.  In that state, it still gave the positive effects, without detracting from the site’s current policies.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The second argument (given by Yemon Choi in comments, and to some extent echoed in the discussion on &lt;a href=&quot;https://meta.mathoverflow.net/questions/4317/catering-to-professional-appearance-a-bit-much&quot;&gt;Catering to professional appearance a bit much?&lt;/a&gt;) is that deleting the whole question “would be a less divisive course of action than selective deletion”.  This would be reasonable if true, but the voting in that thread, plus the discussion at &lt;a href=&quot;https://meta.mathoverflow.net/questions/4317/catering-to-professional-appearance-a-bit-much&quot;&gt;Catering to professional appearance a bit much?&lt;/a&gt;, seems to show that this was in fact a much less popular and more divisive course.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Indeed, suggesting that selective deletion would have been more divisive is, I think, missing the point of the original complaint, or at least, not trusting the MO community to grasp that point.  &lt;strong&gt;The issue with the sexist jokes was not that they were jokes, but that they were sexist&lt;/strong&gt; — and most commenters in the discussion seemed to understand and accept that point, whether or not they supported deleting the jokes in question.&lt;/p&gt;&#xA;" OwnerUserId="2273" LastActivityDate="2019-08-19T00:05:02.733" CommentCount="8" ContentLicense="CC BY-SA 4.0" />

I'll even go a bit further and say that any thread that stood open since 2009 until 2019 without any complaints or controversies is good enough to stand forever and I'd rather risk offending a few good people than letting the &quot;social justice warriors&quot; control the discussions in any way beyond politely voicing their suggestions now and then with which we can freely agree or disagree as a community. I personally have nothing against sexist jokes (as well as jokes about mathematicians, Russians, people above 6 feet tall wearing a mustache and carrying a waist bag at all times, or even direct personal jokes about myself) if they are sufficiently smart and funny, but I wouldn't regret their being gone either if people feel like they are bad taste. However deleting the whole thread with no possibility of reversal is way too much. The appropriate thing to do now, IMHO, is to uncast the final moderator vote and let the community decide either way by regular voting with whatever result emerges being final. By now there is enough publicity around the thread to be sure that most people who care either way will participate in that &quot;tug of war&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The argument about &quot;being welcoming to all&quot; can be easily turned around any time. What attracts some people can repel the others and vice versa and I talk here exclusively about people with good intentions and ability to make valuable contributions to the site. What we should agree upon and enforce is some general standards of discussion and behavior, not the &quot;admissible points of view, language, etc.&quot;. The latter, IMHO, should be governed by the common sense alone and one has to learn to live with the fact that the common sense is subjective and varies from person to person a bit though there are many common points like not being outright disrespectful without a good reason, trying to express yourself in a clear way, sticking to the point, etc.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As to the general question of what is a good/questionable/bad MO question/answer, it seems to me that it is also time and community composition dependent. However, no matter how the corresponding factors fluctuate and drift, it is never a good idea to behave like we live in Orwell's 1984 and try to rewrite the past every time our opinions or official policies concerning the matters undergo a change unless we want to end up with this site (or our historical reality) to be inhabited exclusively by comrades Ogilvy.&lt;/p&gt;&#xA;" OwnerUserId="1131" LastActivityDate="2019-08-24T20:37:01.193" CommentCount="4" ContentLicense="CC BY-SA 4.0" />

Which is probably a good thing.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Lately I've been puzzling with Banach space tensor products and the approximation property, and on multiple occasions found that my search would have been easier if there had been a tag for questions related to the approximation property. It is my impression that it is a whole field of its own, with a rich body of theory and (especially) counterexamples, so to me a tag &lt;code&gt;approximation-property&lt;/code&gt; would make sense.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Since I understand that we don't want to go haphazardly creating new tags for every specialization (or niche) within mathematics, I thought I'd ask what you think.

Indeed, some of them have such arguments in the comments.  I think these questions were mildly entertaining, but they ultimately do not belong on the site permanently.  Each of them, after some time in the sun, was rightfully deleted.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I think it is proper that the jokes thread follow this pattern - it's basically full of weak tea you can find elsewhere on the internet, it was only active during the first 3 months of MathOverflow and just sat around closed for the remaining 97% of our history, and the only reason it was still visible was that no one bothered to suggest deletion earlier.  I had locked it last year with a &quot;historical significance&quot; note, but that was mostly because at the time I didn't feel like dealing with an extended discussion about the merits of deletion.  I now see that that was a mistake, and that such a discussion was more or less unavoidable.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I understand that the sequence of events that led to the recent votes to delete was objectionable to some people, but I don't think that justifies undeleting a thread that doesn't belong here.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(Thanks to Martin Sleziak for the data explorer query that produced the deleted questions with positive votes.)&lt;/p&gt;&#xA;" OwnerUserId="121" LastActivityDate="2019-08-31T02:45:12.893" CommentCount="11" ContentLicense="CC BY-SA 4.0" />

(There are other considerations, a primary one being that the forum follows the Q&amp;amp;A model.) Large enough here probably means over a hundred active participants, with a minimum amount of traffic of ten or so questions daily.

These are separate issues, but have both contributed to a wide feeling (expressed through community voting and extensive commenting) that SE Inc. is making a mess of things, one way or another.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Since MathOverflow uses the SE platform, but is actually &lt;a href=&quot;https://meta.mathoverflow.net/questions/969/who-owns-mathoverflow&quot;&gt;a different organisation&lt;/a&gt; it is not clear what exposure (in the sense of risk) MO has to the recent controversies. Are our moderators bound by the same agreement as the SE network moderators? Will the CoC apply here, when it is finally sorted out? Were contributions to MO retroactively relicensed (making &lt;a href=&quot;https://meta.mathoverflow.net/questions/950/who-owns-my-mathoverflow-posts&quot;&gt;this question&lt;/a&gt; outdated)?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Again, the intent of this question is not the &lt;em&gt;content&lt;/em&gt; of the CoC or the relicensing issue, but to get in writing the facts of where MO stands in relation to these from a contractual/legal/etc way.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Edit&lt;/strong&gt; (To clarify some things) I asked this question in a slightly vague way, partly because I didn't want to pre-empt any position or bring up debates here. But I've read a bit more, and Johannes pointed out some relevant facts in an answer. So here are some more focussed questions. Again, this is &lt;strong&gt;not to debate the merit or otherwise of the below points&lt;/strong&gt;, I'm looking for official answers from mods or MO owners/board members on policy about changes that StackExchange Inc makes.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;StackExchange relicensed all contributions users had made to their websites (from CC-By-SA 3.0 to CC-By-SA 4.0, which change the CC people say can't be made without permission), but this has also relicensed all MathOverflow content too. Is this compatible with &lt;a href=&quot;https://drive.google.com/file/d/1-Rx93qiEH3t9wAwsyvuVzjawF62X6OgI/view&quot; rel=&quot;nofollow noreferrer&quot;&gt;the agreement between the MathOverflow corporation and StackExchange Inc&lt;/a&gt;?&lt;/p&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I presume that there is very little objection to the principles of the new Code of Conduct (CoC), and find it nigh-impossible to forsee any circumstances in which MathOverflow as an organisation would object to the now in-position wording, and adopting the CoC as official here (were it a choice). However, the official FAQ on the CoC, which has given rise to concerns among many StackExchange users, is getting rather distant from any document that I can see referred to under the legal agreement between MathOverflow and StackExchange Inc. The CoC is linked to from MathOverflow pages, and so is, it seems, in effect and binding. I haven't seen, after some cursory clicking about, explicit links from MathOverflow to the contentious FAQ. Does this latter nonetheless carry force on MathOverflow to the extent it does on the StackExchange network? Will all future policy changes in the same manner also immediately and automatically apply on MathOverflow? (Added: I note that this type of question was raised &lt;a href=&quot;https://meta.mathoverflow.net/questions/969/who-owns-mathoverflow#comment4931_970&quot;&gt;nearly six years ago&lt;/a&gt;, to which it seems the official answer was, to paraphrase, MathOverflow has an informal understanding with StackExchange Inc that SE Inc employees shouldn't interfere with our moderation as we can choose to leave the network. However, this seems to me to be a bit like &lt;a href=&quot;https://www.youtube.com/watch?v=JKbDKsNsjac&quot; rel=&quot;nofollow noreferrer&quot;&gt;the nuclear deterrent&lt;/a&gt;...)&lt;/p&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Perhaps all of this is moot.

So if a bounty is auto-awarded, the reputation earned by the answerer is therefore a multiple of 25 which can be odd - depending on the size of the original bounty.. (More details on bounties and auto-awarding can be found &lt;a href=&quot;https://mathoverflow.net/help/bounty&quot;&gt;in the help center&lt;/a&gt; and in this FAQ post: &lt;a href=&quot;https://meta.stackexchange.com/q/16065&quot;&gt;How does the bounty system work?&lt;/a&gt;)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Some additional points:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;If the only possible reputation changes were by an even number, you would expect the total reputation of a user to be &lt;em&gt;odd&lt;/em&gt;, since a new user starts with 1 reputation point. (Or with 101, if the user got &lt;a href=&quot;https://meta.mathoverflow.net/tags/association-bonus/info&quot;&gt;association bonus&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;A user cannot have total reputation below 1 reputation point. So even if somebody gets enough downvotes that would get them to negative numbers, only part of the reputation is deduced. (It is cut off after the user gets to 1 reputation point.) &lt;/li&gt;&#xA;&lt;li&gt;There is also the &lt;a href=&quot;https://meta.stackexchange.com/tags/daily-reputation-limit/info&quot;&gt;daily reputation cap&lt;/a&gt; on reputation from upvotes/downvotes and suggested edits at 200 reputation points. That means that sometimes part of the reputation increase is not counted - if the reputation from votes and suggested edits would exceed 200 reputation points. (For example, from an upvote you get only 6 reputation points if you were already at 194 on that day.) However, this cannot influence parity, since the total is 200 reputation points.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;I will also add that you can audit your reputation on this link: &lt;a href=&quot;https://mathoverflow.net/reputation&quot;&gt;https://mathoverflow.net/reputation&lt;/a&gt; (It is similar to your &lt;a href=&quot;https://mathoverflow.net/users/current?tab=reputation&quot;&gt;reputation tab&lt;/a&gt;, but this link is probably better if you want to check many various days.)

They usually underestimate the value of having a stable rule-set, and overestimate the beneficial impact that the rule change will have.  A good example of this IMO is chess. Changing the rule that capturing the king wins the game, to the rule that  checkmate wins the game (and moving into check is illegal) accomplished nothing other than to make the game harder to teach, and make the stalemate rule seem bizarre.  &lt;b&gt;If it ain't broke, don't fix it.&lt;/b&gt; Neither +5 nor +10 for questions is &quot;broken&quot; IMO, so I'm not in favor of fixing it.&lt;/p&gt;&#xA;" OwnerUserId="3106" LastActivityDate="2019-11-25T21:05:40.547" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

Concerning the removal of some of the badges, notice specifically this part: &quot;We also identified a small number of users who will receive duplicate badges on the initial rollout of the new logic - meaning they were awarded for a question with the old logic, but now are being awarded for an answer - the duplicate badges will be removed over the next few days after the corrected badges are awarded.&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This seems to be the most likely explanation. If I understand the quoted part correctly, for each removed badge you should have been awarded a new badge for link to an answer in the recent recalculation. You can check whether the counts seem reasonable using this &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;SEDE&lt;/a&gt; query: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1167513/publicity-badges-awarded-within-a-given-period&quot; rel=&quot;nofollow noreferrer&quot;&gt;Publicity badges awarded within a given period&lt;/a&gt;. (&lt;s&gt;However, the new badges will be shown there only after the next update of the database - so you have to wait a day or two or to count manually.&lt;/s&gt; The query shows that you were awarded 125 Announcer badges and one Booster badge in the dates near the recalculation. So some of those might be badges for answers - which replaced the badges for questions which were taken away. Of course, the same query can be used also for &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1167513/publicity-badges-awarded-within-a-given-period?Date1=2009-01-01&amp;amp;Date2=2020-01-01&quot; rel=&quot;nofollow noreferrer&quot;&gt;any other date range&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The linked post contains also further details on the recent change. I will add a link also to a related posts on Mathematics Meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/31007&quot;&gt;Change in computation of “Announcer” badges?&lt;/a&gt; (Although that one does not discuss the possible removal of badges.)&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Of course, the count is not important in any meaningful way, and I hardly notice it usually. But I don't usually expect it to go down.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;Indeed, under normal circumstances, the only type of badges that are taken away are tag-badges. (If you no longer fulfill the criteria.) Other situations when a badge is removed seem to be rather exceptional and very likely rare. See: &lt;a href=&quot;https://meta.stackexchange.com/q/58053&quot;&gt;Is it possible to lose badges?&lt;/a&gt; and the section &quot;What can cause a badge to be lost/revoked/taken away after it is awarded?&quot; of the FAQ post &lt;a href=&quot;https://meta.stackexchange.com/q/17853&quot;&gt;How do “badges” work?&lt;/a&gt; (On Mathematics Meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/6848&quot;&gt;Can badges be unearned?&lt;/a&gt; and &lt;a href=&quot;https://math.meta.stackexchange.com/q/21815&quot;&gt;Can an awarded tag-badge be withdrawn?&lt;/a&gt;)&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2019-12-15T12:20:17.147" LastActivityDate="2019-12-15T12:20:17.147" CommentCount="1" ContentLicense="CC BY-SA 4.0" />

I was considering adding a bounty, but since (to my humble understanding) the question seems to be of research level, I was wondering if it would be appropriate to post it here instead after a week or two, in the case that I get no feedback in MSE during that time.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Of course I would reword the question to make it more concise, and perhaps modify its scope to avoid duplication of content.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Around eight months ago I did a similar thing with another question (&lt;a href=&quot;https://math.stackexchange.com/questions/3203167/which-root-lattices-have-a-theta-series-with-this-property&quot;&gt;MSE version&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/333086/which-even-lattices-have-a-theta-series-with-this-property&quot;&gt;MO version&lt;/a&gt;). The question turned out to be well-received here and had a helpful answer. But I think this case is different, because it is about a generalization that I haven't seen even mentioned in the literature I've checked, and since I'm not a professional mathematician (my background is in physics) I don't have the knowledge to discern whether it's because it has a trivial answer, because it is too broad to answer or even if the question is ill-posed.&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Is my question suitable for MathOverflow in its current state?

An example is &lt;a href=&quot;https://mathoverflow.net/questions/349629&quot;&gt;How to compute the volume of a region transformed by a matrix?&lt;/a&gt; , which I recently took the liberty of rewriting. If I understood the OP's question correctly, it is definitely a topic of current research. For example, Alex Barvinok and Michael Joswig think about the sort of polytope questions I raise. I am less familiar with the semidefinite programming literature, but Pablo Parrilo and Cynthia Vinzant are two people who think about variable elimination in nonpolyhedral convex geometry. It strikes me as unlikely that this question would get a good answer on math.SE ; it is not a textbook topic.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;At the same time, there are a lot of clues in the OP's phrasing that suggests they are not at a level to understand this literature.

In order to maintain such a resource, it needs to be helpful to the maintainers foremost.  That means providing &quot;MathOverflow quality &quot;  responses.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Remember that being helpful on this forum is primarily to give succinct answers to questions.  We are not a help desk, or a Wikipedia extension, or a replacement for someone doing a web search; we provide a service that allows other researchers to make further progress in their work, with the side benefit that other readers can also benefit from such answers.  Often this service is &quot;Yeah, it's been done before: use this search term and check these links.&quot;, which is essentially literature orientation that most others can't do without spending substantial time learning the subject.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Sometimes the service is to sketch the idea of solution, and hope the reader has enough chops to fill out the sketch. Even among MathOverflow regulars, the filling out can be substantial work, but there is still time saved because a helpful idea is presented.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If a poster does not have the experience to appreciate the given answer, there is not much we can do on the forum itself.

However, you can write brief comments and provide links.  I and other members of long standing should have no issue with you providing a link in your answer to ancillary material (tutorials, filled out sketches, reading lists with commentary) that you develop.

This situation appears often when people doing research encounter problems that require tools outside their areas of expertise.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have seen two ways you can use MathOverflow to connect people with experts.  The easy way is for you to leave a comment or answer citing the relevant work - then the questioner has some names to look up.  A more direct method is for you to contact an expert you know, and inform them that there is a question close to their subject.  At some point, however, it is the questioner's responsibility to run with the leads they are given.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As far as site norms are concerned, I suggest we be more charitable about leaving questions of this nature open.  Unfortunately, it can be hard to separate these questions from those that are not research-relevant, and we have an interest in keeping the site on-topic.  One possible rule is that if a known specialist says that a question has research interest, then perhaps we should give that question the benefit of the doubt.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I encourage experts to revise questions that touch on research-level mathematics to make the on-topic part more visible, and to give answers that address research-level aspects of a question where it is not obvious (Joel David Hamkins has been particularly good at this).

The OP answered his own question within 13 hours of asking it, and has now edited his answer 26 times, so that it is always on the front page. The OP discloses that he co-moderates a blog, and is gathering information for the blog. To me, this question/answer combo would be much more appropriate as a blog post or website, than as a mathoverflow post. I feel that mathoverflow is best when questions have an answer that can reasonably be believed to be fixed in time, rather than an answer that must be edited over and over again as problems are checked off the open problem list. There was &lt;a href=&quot;https://mathoverflow.net/questions/135765/open-problems-in-algebraic-topology-and-homotopy-theory&quot;&gt;another example years ago&lt;/a&gt;, and I held off on writing a giant CW answer that would be edited as problems were solved, because of this concern. &lt;a href=&quot;https://mathoverflow.net/questions/100808/properties-of-functors-and-their-adjoints&quot;&gt;Here is another example&lt;/a&gt;, where the question was edited 14 times as the OP learned more and more properties, and no satisfactory answer was possible, because it's impossible to enumerate all nice properties.&lt;/p&gt;&#xA;&lt;p&gt;My questions are:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;(1) Is the current question about Stanley's 1999 list appropriate, given that the answer will need to be edited in perpetuity to remain a correct answer in future years?&lt;/p&gt;&#xA;&lt;p&gt;(2) In general, should we vote to close when we see questions like the three linked above, which require a zillion edits to create a big list?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Note that, when it was a &lt;a href=&quot;https://mathoverflow.net/questions/28/latex-based-document-editors&quot;&gt;question about the best LaTeX editor&lt;/a&gt; or a &lt;a href=&quot;https://mathoverflow.net/questions/49384/tools-for-long-distance-collaboration&quot;&gt;question about tools for collaboration&lt;/a&gt;, the &lt;a href=&quot;https://meta.mathoverflow.net/questions/4366/what-to-do-if-you-want-up-to-date-answers-to-an-old-question-on-technology&quot;&gt;community decided&lt;/a&gt; it would be better to have a new question to get updated answers, rather than constantly reviving the old question.&lt;/p&gt;&#xA;" OwnerUserId="11540" LastEditorUserId="-1" LastEditDate="2020-06-15T07:25:55.780" LastActivityDate="2020-01-08T16:10:47.963" Title="Are questions appropriate if they require answers to be edited in perpetuity?"

I wonder whether it would be helpful on MO to make one of the tags a synonym of the other. (If I understand correctly, tag synonyms are not symmetric, as one tag remains the primary tag.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Note the following (also used in my &lt;a href=&quot;https://math.stackexchange.com/a/1971588/118539&quot;&gt;answer&lt;/a&gt; to a Mathematics Stack Exchange question asking about algebraic dynamics):&lt;/p&gt;&#xA;&#xA;&lt;p&gt;From &lt;a href=&quot;https://ncatlab.org/nlab/show/algebraic+dynamics&quot; rel=&quot;nofollow noreferrer&quot;&gt;nLab&lt;/a&gt;:&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;In &lt;strong&gt;algebraic dynamics&lt;/strong&gt; one typically studies discrete dynamical systems on algebraic varieties.

I think the list of the problems from Stanley is good, but as it does not hold my interest for long, I am more aware of the post &quot;being in my way&quot;, and pushing other content to the side.  I won't put it on an ignore list, and I will tolerate it more when the updates are less frequent.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I tend to contribute material from a cell phone, so I don't have a convenient preview and thus have to make several successive changes to a post of mine, some of which get collapsed in the edit history to a single edit. So I expect and tolerate in other posts a flurry of initial edits, followed by a near exponential drop off as things stabilize, in post submissions.  However, for some things where results of an ongoing computation are reported for something that holds my interest, then I hope for periodic updates.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;This might be a feature request in disguise: for each question post, allow an alert factor: if I follow the question or associated answers, set the alert factor high so that I get info on every update, while if I prefer not to see it casually, I set it lower so that I am not informed of edits until a day has passed since I was last informed.  There are other settings that may be useful, and it should be like a form of favorites list that could be done with browser side scripting.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Gerhard &quot;Don't Bother Me, I'm Reading&quot; Paseman, 2020.01.08.&lt;/p&gt;&#xA;" OwnerUserId="3402" LastActivityDate="2020-01-08T16:10:47.963" CommentCount="1" ContentLicense="CC BY-SA 4.0" />

From these posts I understand that the moderators &lt;a href=&quot;https://meta.stackexchange.com/q/116793&quot;&gt;can see the past diplaynames&lt;/a&gt;. So one solution to see the older usernames would be becoming a moderator - however this is only feasible for small fraction of users.&lt;/p&gt;&#xA;&lt;p&gt;As Todd Trimble &lt;a href=&quot;https://meta.mathoverflow.net/questions/4426/recognizing-identifiable-users-changing-user-names#comment21455_4426&quot;&gt;mentioned in a comment&lt;/a&gt;, older usernames can appear in past replies directed at that user:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;This is hit or miss, but when people ping users in comment threads, the old name after the @ doesn't change. So if you are sufficiently determined, you can try scouring old comment threads.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;So if at least one &lt;a href=&quot;https://meta.mathoverflow.net/tags/comment-notification/info&quot;&gt;comment reply&lt;/a&gt; in the form &lt;code&gt;@username&lt;/code&gt; was directed at a particular user while he had some username, the username could be obtained from this.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Comment replies from API&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Stack Exchange API has a method to &lt;a href=&quot;https://api.stackexchange.com/docs/mentions-on-users&quot;&gt;get all comments where the given user was mentioned&lt;/a&gt;. From this, usernames used in those comments could be obtained. In fact, there used to be an application on Stack Apps for this purpose: &lt;a href=&quot;https://stackapps.com/q/6276&quot;&gt;Find old display names of a user&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;The link provided in that post is no longer working, but some version can be seen in Wayback Machine &lt;a href=&quot;http://web.archive.org/web/20160726060006/http://normalhuman.github.io/oldusernames/&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt; and &lt;a href=&quot;http://web.archive.org/web/20160208094202js_/http://normalhuman.github.io/oldusernames/usernames.js&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;I have tried to copy-paste the version from Wayback Machine and edit it a bit - and I got some working version here: &lt;a href=&quot;http://msleziak.com/stackexchange/oldusernames/&quot; rel=&quot;nofollow noreferrer&quot;&gt;http://msleziak.com/stackexchange/oldusernames/&lt;/a&gt; (You can also see some screenshots in the &lt;a href=&quot;https://chat.stackexchange.com/rooms/9369/conversation/old-usernames&quot;&gt;linked chat transcript&lt;/a&gt;.) I was pleasantly surprised that this works also for deleted users.&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;I should say that I have no experience with JavaScript whatsoever, so I was basically copying some stuff without really knowing what it does. Probably there are many users around here who would be able to create a much better version from this.&lt;/sup&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Comment replies using SEDE&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;I have mentioned also some related posts on Mathematics Meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/22528&quot;&gt;To whom am I replying?&lt;/a&gt;, &lt;a href=&quot;https://math.meta.stackexchange.com/q/4998&quot;&gt;List earlier display names for an account&lt;/a&gt; and to some extent also &lt;a href=&quot;https://math.meta.stackexchange.com/q/30738&quot;&gt;Is it possible to know the name of a user with account deleted?&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;You can find there some &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;SEDE&lt;/a&gt; queries which check replies in posts and comments. Naturally, there will be many false positives. (In some comment which is under my post or follows my comment, people can use &lt;code&gt;@username&lt;/code&gt; also to notify somebody else who was involved in the conversation. But there is at least some likelihood that my username might appear in such comments quite often.)

In the case of deleted user, the string &lt;code&gt;user{id}&lt;/code&gt; is displayed instead of username, so in that case you can see the id immediately.&lt;/p&gt;&#xA;&lt;p&gt;(In the above links I have used the OP of this question for the first two queries and &lt;a href=&quot;https://meta.mathoverflow.net/questions/2827/what-happened-to-the-dear-user-quid-9072-they-appear-deleted&quot;&gt;quid&lt;/a&gt; as an example of deleted user. Maybe some user on MO who often changes their username would be better for testing purposes - but I wasn't able to think of such user.)&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Further comments&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Whether you're using API or SEDE, you can try both main and meta. As users are typically more active on main than on meta, the results from main will probably be more helpful.&lt;/p&gt;&#xA;&lt;p&gt;Both solutions basically search in comments for strings starting with &lt;code&gt;@&lt;/code&gt; until the end of the word. End of the word is decided in JavaScript by using regular expression &lt;code&gt;/@\w+\b/&lt;/code&gt;, so it ends on &lt;a href=&quot;https://www.w3schools.com/jsref/jsref_regexp_begin.asp&quot; rel=&quot;nofollow noreferrer&quot;&gt;the metacharacter \b&lt;/a&gt;. In SEDE it is until the next space or characters such as &lt;code&gt;:&lt;/code&gt;, , &lt;code&gt;,&lt;/code&gt;. or &lt;code&gt;.&lt;/code&gt; (colon, comma or full stop). In practice that means that it won't work on some usernames. For example, since &amp;quot;S. Carnahan&amp;quot; has a dot in his username, you will only get &amp;quot;S&amp;quot; when a comment contains &lt;code&gt;@S.Carnahan&lt;/code&gt;.&lt;/p&gt;&#xA;&lt;p&gt;Another consequence of the way it works is that we get also shortenings of the username which somebody used in a &lt;a href=&quot;https://meta.mathoverflow.net/tags/comment-notification/info&quot;&gt;comment reply&lt;/a&gt;. For example, if somebody responds to me, both &lt;code&gt;@Martin&lt;/code&gt; and &lt;code&gt;@MartinSleziak&lt;/code&gt; will work (and I'll get notification about such comments; more details can be found here: &lt;a href=&quot;https://meta.stackexchange.com/q/43019&quot;&gt;How do comment @replies work?&lt;/a&gt;). So if somebody used the shorter form, &amp;quot;Martin&amp;quot; will also appear in the list obtained by the above script. (Despite the fact that my username at the time was longer.)&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2020-07-30T18:41:37.153" LastActivityDate="2020-07-30T18:41:37.153" CommentCount="3" ContentLicense="CC BY-SA 4.0" />

The Test Site shall be a fully-functioning, fully operational version of MathOverflow running under the latest Stack Exchange software, which MathOverflow may test &amp;quot;and otherwise use before the migration is complete. MathOverflow and you acknowledge and agree that any changes made by you or MathOverflow in the Test Site will be lost following the final migration to MathOverflow 2.0. The migration will be performed by StackExchange only after receiving written approval from MathOverflow, which approval may be communicated via email. After migration, MathOverflow will remain exclusively located at the MathOverflow Domains.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Stack Exchange acknowledges that Moderators may wish to make reasonable adjustments to the operation of MathOverflow 2.0 by means of extra clientside JavaScript. Thus, Moderators shall be permitted to submit additional JavaScript to Stack Exchange which, if it does not compromise the technical integrity of the network, will be inserted into the footer, allowing some reasonable modification of the site that is specific to MathOverflow 2.0. MathOverflow and you acknowledge and agree that the Stack Exchange 2.0 HTML is changing all the time, and accordingly, such JavaScript will need to be actively maintained by the Moderators or it may stop working.

After the question is closed, the close voters are displayed together with the close reason to 3k+ users, and any user can see them in the timeline and the revision history. (A question might enter close votes review queue also after a &lt;em&gt;flag&lt;/em&gt; to close rather than vote to close - but from the wording it seems that you actually saw close votes in this case. So you're probably mostly interested in the initial close vote.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;What regular users see is the number of close votes which have already been cast (&lt;a href=&quot;https://mathoverflow.net/help/privileges/close-questions&quot;&gt;shown to 3k+ users&lt;/a&gt;). Users who have &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;10k+ reputation&lt;/a&gt; can also recent history &lt;a href=&quot;https://mathoverflow.net/review/close/history&quot;&gt;in the review queues&lt;/a&gt;, including the posts reviewed by others. (Any user can see the votes if they get the link to the review from somewhere - but 10k+ users have links to recent reviews available in the review history.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Also &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;Data Explorer (SEDE)&lt;/a&gt; can be used to see whether there is larger number of posts in the review queues. (Although one should keep in mind that the data in SEDE are updated only once a week.) Some examples of queries which might be useful in connection with this: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1195507/questions-entered-in-the-review-queue-in-the-date-range&quot; rel=&quot;nofollow noreferrer&quot;&gt;Questions entered in the review queue (in the date range)&lt;/a&gt;, &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1195508/number-of-questions-in-a-review-queue-per-day#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;Number of questions in a review queue per day&lt;/a&gt;, &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1195509/number-of-questions-in-a-review-queue-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;Number of questions in a review queue per month&lt;/a&gt;. (I will mention that the questions which have been deleted before the last update will not show among the results. But my impression is that questions aren't deleted on MO too quickly - perhaps with the exception of questions which are completely off-topic.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Moderators&lt;/em&gt; can check on moderators' timeline of a post who cast the first close vote. Although this has to be done separately for each post, I suppose that if many closures were initiated by the same user, the pattern will be noticed after checking several posts. (And posts which need to be checked can be found through review queues or using SEDE.) I will quote here in full animuson's answer from: &lt;a href=&quot;https://meta.stackexchange.com/q/268203#268206&quot;&gt;Can moderators see the close/reopen &lt;em&gt;votes&lt;/em&gt; (and &lt;em&gt;not&lt;/em&gt; the reviews)?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;blockquote&gt;&#xA;  &lt;p&gt;Yes, diamond moderators have access to a special timeline &lt;strong&gt;on posts&lt;/strong&gt; which does list all close and reopen votes (and who cast them) inside it, including any that have expired or otherwise no longer count. Close and reopen votes are the &lt;em&gt;only&lt;/em&gt; votes that they see in that timeline, though. This information proved valuable to me, as a moderator on Stack Overflow, countless times in determining what happened with a question, whether it be related to review or not.&lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;Moderators do not have access to go to a user's profile and look at all the close and reopen votes a user has cast (because they don't have access to the votes tab on your profile).&lt;/p&gt;&#xA;  &#xA;  &lt;p&gt;Non-diamond users cannot see anything about close and reopen votes outside of the count that is provided in the link and the names provided in the revision history.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;I am not a moderator on any site, so I cannot check this for myself. However, I consider the information in the linked post reliable. (Moderators are in better position to answer this question, but since some time has passed without any reply from a moderator, I have posted at least an answer with the information which I was able to find.)&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Is that a problem?&lt;/strong&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You have also asked: &quot;Do we have any safeguards against drive-by sessions or is it just an inevitable &quot;occupational hazard&quot; of using the site?&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Similarly as many other things, there is a daily limit on the number of close votes. According to &lt;a href=&quot;https://meta.stackexchange.com/q/164899&quot;&gt;The Complete Rate-Limiting Guide&lt;/a&gt; (&lt;a href=&quot;https://meta.stackexchange.com/revisions/164900/117&quot;&gt;current revision&lt;/a&gt;), the limit is &quot;50 close/reopen votes/day/user on Stack Overflow, Mathematics, Server Fault, Super User and Ask Ubuntu, 24 on others&quot;.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Another thing which helps is that five users are needed to close a question. (With some exceptions, such as close votes by moderators and duplicate close votes using &lt;a href=&quot;https://meta.stackexchange.com/tags/dupehammer/info&quot;&gt;dupehammer&lt;/a&gt; by gold badge holders.) So perhaps the main issue is not whether somebody voted to close a question which really deserves closing rather whether they voted on several posts short after each other. (Of course, different users have different criteria on what is on-topic on MathOverflow and what should be closed.) A close vote pushes the post in the review queue where it is seen by other users who decide whether the post should be closed or left open. And if there aren't enough reviewers, the close vote will eventually age away.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So basically the only problem caused by this is that there is a larger number of posts in the review queues and more work for reviewers. However, on a healthy site which has enough users caring about site maintenance and community moderation, even if there is occasional increase of the posts to be reviewed, they will be eventually dealt with. (Whether or not the situation with community moderation and related issues on MathOverflow is good or not probably depends on your standards.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;I will also add that only 3k+ users can cast close votes. Hopefully, most users who reached this level should already have a good idea how the site works and what is on-topic/off-topic. So one can expect that they use the privilege to cast close votes responsibly. (One of the purposes of reputation is to achieve that various privileges are given to users who already have sufficient experience with the site.)&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2020-02-13T14:44:51.620" LastActivityDate="2020-02-13T14:44:51.620" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

One way I haven't seen mentioned is one that just now happened to me, and (though my memory is a little vague) probably not for the first time:&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In the course of trying to devise a homework problem in game theory (!), I stumbled onto an extremely complicated looking expression involving multiple values of multiple polygamma functions.  Mathematica told me that my expression, evaluated at any positive integer, is always rational.  This was useful for my application, but it appeared to be a sheer miracle.  I've spent the better part of the past week trying to demystify that miracle.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Finally I decided it was time to unleash the power of MathOverflow, and carefully composed a question that I then hesitated to post, for fear that I'd missed something obvious.  So I spent the better part of the past day going over and over my draft of that question, just to make sure.  &lt;/p&gt;&#xA;&#xA;&lt;p&gt;And tonight, I had one of those &quot;Aha! It &lt;b&gt;is&lt;/b&gt; obvious!&quot; moments.  I now understand exactly what's going on.  I also see, beyond any shadow of any doubt, that it really &lt;b&gt;should&lt;/b&gt; have been obvious days ago, and I have no doubt that if I'd posted it, any number of people would have been quick to see what it took me a week to decipher, and I'd have thanked them profusely, and I'd have felt glad to have my answer, and only a little sheepish.  So that would have been a good outcome.  But getting it on my own means I had a series of minor insights I will never, ever, ever forget, and that's an even better outcome.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Moreover---and this is really the point---if MathOverflow hadn't been there, I might have decided three days ago that this problem was just too hard for me, and given up on it.  Knowing that I could almost surely get my answer by posting ruled out giving up.  And then fear of embarrassing myself ruled out posting.  The only remaining option was to solve my problem.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;So MathOverflow just made me a little smarter by making me feel just a little intimidated about revealing how un-smart I might be (and in fact, in this instance, turned out to be).

For me, when grappling with a new problem, it's really become an integral part of my process to try to formulate sub-problems and related questions as MO questions. Only in a minority of cases does this result in actually asking an MO question (in which case the answers are typically helpful, of course), but the other cases are often like this -- the process of formulating a question properly leads me to solve it or to realize I should be asking a different question. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;Sometimes I even get to the point of writing down my MO question in the actual question box on the website before understanding the answer myself, and usually this is because the question-writing process has gotten me there. This is because the writing process forces me to ask questions like&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Have I framed this properly?&lt;/li&gt;&#xA;&lt;li&gt;Have I followed up on the obvious leads in the literature?&lt;/li&gt;&#xA;&lt;li&gt;Have I crunched through the most straightforward, obvious first steps?&lt;/li&gt;&#xA;&lt;li&gt;What will the first comment be? Can I address it ahead of time to advance the starting point of the conversation?&lt;/li&gt;&#xA;&lt;li&gt;...&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Sometimes this shows -- for example, &lt;a href=&quot;https://mathoverflow.net/questions/352803/what-do-you-call-a-map-of-spaces-which-is-weakly-left-orthogonal-to-all-n-conn&quot;&gt;this question&lt;/a&gt; is a case where the process of formulating an MO question led me to answer it myself, but in this case I had just posted the question before I realized that in writing out the question properly, I had already answered it. It was a bit embarrassing, but looking back I think it offers a window into how one can use MO to bring some order to one's thought process.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Even when it works out differently, sometimes there are spin-off questions which make it onto MO as being of independent interest even as I realize they're not as central to my research as I originally thought. &lt;a href=&quot;https://mathoverflow.net/questions/353464/when-are-projective-modules-closed-under-highly-filtered-colimits&quot;&gt;This one&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/questions/354415/is-there-a-model-independent-characterization-of-the-gaunt-strict-n-categories&quot;&gt;this one&lt;/a&gt; are recent examples for me.&lt;/p&gt;&#xA;" OwnerUserId="2362" LastActivityDate="2020-03-19T14:37:35.837" CommentCount="3" ContentLicense="CC BY-SA 4.0" />

I am not asking a question here, but I feel obliged to share it.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;I have one rather practical answer, which does not answer the question in the body, but possibly in the title.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I was very surprised to learn that a (small) hospital in my home town was doing their scheduling (&quot;rostering&quot; might be the correct term, but I don't know) by hand.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;They were clever enough to ask for help just in time. Again surprisingly: informally via a mathematician they knew privately. Thus, they now have a professional university team developing a plan that fits their new needs - minimal service, minimizing the probability that a large portion of their staff simultaneously drops out.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I guess that such a strategy might also make sense for other community services, who might not even be aware of this fact.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;(Disclaimer: I am not helping with the implementation, but I was lucky to know someone who knew someone who was a professional in this field, who luckily agreed to do it.)&lt;/p&gt;&#xA;" OwnerUserId="3032" LastActivityDate="2020-03-26T22:06:55.097" Title="An answer to an unposed question" Tags="|discussion|" AnswerCount="0" CommentCount="1" ContentLicense="CC BY-SA 4.0" />

(I only know very basics of SQL, but I hope that somebody more knowledgeable might have a look and spot if I made some mistakes in the queries. I have checked at least some of the numbers &lt;a href=&quot;https://chat.stackexchange.com/rooms/19138/conversation/sede-queries-numbers-of-answers-on-mo&quot;&gt;here in chat&lt;/a&gt;.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I have linked to queries for MO below, you can switch to other sites if you want to compare the statistics.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For the sake of simplicity, I am grouping the data by month. (In this way we're comparing months with different number of days, but probably this difference is not that significant, especially considering some seasonal changes such as Christmas or academic year which might have bigger effect.) Here is the &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223741/number-of-questions-answers-posts-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;number of questions/answers/all posts per month&lt;/a&gt; (and a corresponding query which &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1224831/number-of-questions-answers-posts-per-month-including-deleted-posts#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;includes deleted posts&lt;/a&gt;).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;We can compare this with other statistics about the site:&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;We can look at the &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223752/ratio-answers-questions-posted-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;ratio of answers posted to questions posted&lt;/a&gt; (and the same query &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1224832/ratio-answers-questions-posted-per-month-including-deleted-posts#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;including deleted posts&lt;/a&gt;).&lt;/li&gt;&#xA;&lt;li&gt;We can compare this with number of active users. Since number of users who visited the site is not available in SEDE, we can try to use users who &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1214820/number-of-users-with-at-least-one-post-monthly?Date1=2000-01-01#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;made at least one post&lt;/a&gt; or users who &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1214815/number-of-users-with-at-least-on-comment-monthly?Date1=2000-01-01#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;made at least one comment&lt;/a&gt; as a proxy. Depending on which of the two measures we take, we get this number of posts/questions/answers per active user: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223744/number-of-posts-per-one-active-user#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;query 1 - posts&lt;/a&gt;, &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223745/number-of-posts-per-one-active-user#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;query 2 - comments&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Another statistical datapoint available is number of views of the questions. It is expected that older questions have more views, since they had more time to accumulate them, here is &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1212428/total-number-of-views-by-month-of-creationdate#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;the corresponding graph&lt;/a&gt;. We can ask how the number of answers per one view evolves depending on the age of the question, &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223756/ratio-of-answercount-to-viewcount-by-month-of-creationdate-of-the-question?Date1=2000-01-01#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;we get this query&lt;/a&gt;. (Although it is probably expected that after certain time the questions are more likely to get new views than new answers, so the data from here do not have a straightforward interpretation.)&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223768/average-answercount-depending-on-month-of-questions-creationdate?Date1=2000-01-01#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;This query&lt;/a&gt; returns average answerscount (depending on the age of the question).&lt;/li&gt;&#xA;&lt;li&gt;If we are looking at number of answers, perhaps also number of unanswered questions (=questions with no answers) might be of interest. Here is &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223776/number-of-unanswered-question-zero-answers-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;number&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223781/percentage-of-unanswered-question-zero-answers-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;percentage&lt;/a&gt; of such questions depending on month when the question was posted.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;In the question (and the comments &lt;a href=&quot;https://meta.mathoverflow.net/questions/4505/does-the-number-of-answers-really-drop-over-years#comment21851_4505&quot;&gt;here&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/questions/4505/does-the-number-of-answers-really-drop-over-years#comment21855_4505&quot;&gt;here&lt;/a&gt;) it was suggested that we could measure also number of answers and total score of all answers combined.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;In &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223730/number-of-votes-on-answers-and-votes-on-questions-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;this query&lt;/a&gt; you can see how numbers of upvotes cast on questions/answers/all posts evolves over time. (This query takes into consideration the date when the vote was cast, rather than the date when the question was posted.)&lt;/li&gt;&#xA;&lt;li&gt;Here is &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223759/average-score-of-all-answers-depending-on-month-of-questions-creationdate#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;a query&lt;/a&gt; which calculates average &quot;total score of all answers&quot; (i.e., sum all scores of the answers) depending on month when the &lt;em&gt;question&lt;/em&gt; was posted. (In case this &quot;total answer score&quot; seems interesting to you, here is a &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223758/total-score-of-answers-for-the-question&quot; rel=&quot;nofollow noreferrer&quot;&gt;query that can be used to get it for individual questions&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;It was &lt;a href=&quot;https://meta.mathoverflow.net/questions/4505/does-the-number-of-answers-really-drop-over-years/4510#comment21887_4505&quot;&gt;pointed out by Will Sawin&lt;/a&gt; that at the beginnings of MO there were more big-list questions, which might influence the number of answers. We might check for these by looking at some specific tags, or by taking into account only non-CW posts. (Originally I used in tag-related queries simply the AnswerCount, which meant that an answer was counted in the month when the &lt;em&gt;question&lt;/em&gt; was posted. I reworked the queries since then, in the queries where this is applicable the answers should be counted based on the date when the &lt;em&gt;answer&lt;/em&gt; was posted.)&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The fact that number of CW posts is now lower can be confirmed &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1225028/number-of-questions-answers-posts-per-month-only-cw#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;by this query&lt;/a&gt;.

(This answer was made &lt;a href=&quot;https://meta.mathoverflow.net/tags/community-wiki/info&quot;&gt;community wiki&lt;/a&gt;, so that other users who know more about this can add more information to this answer.) Of course, you can get much more detailed information by reading the linked posts.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&quot;Off topic&quot; was renamed to &quot;community specific reason&quot;. In the past there was some dissatisfaction with the name &quot;off-topic&quot;, since in some cases it was related closer to the quality and the type of the question rather than to the topic of the question. (To use an example from Math Overflow, it often happens that the question is not research level, but the topic of the question - such as number theory, group theory, linear algebra, etc. - belongs on the site. So the question is made unsuitable by its level rather than by its topic.) Some related discussions: &lt;a href=&quot;https://math.meta.stackexchange.com/q/26524&quot;&gt;A feature requested for the purpose of avoiding unintentional newbie-biting&lt;/a&gt; on Mathematics Meta and &lt;a href=&quot;https://meta.stackexchange.com/q/186024&quot;&gt;Can we rename the off-topic close reason label on the primary screen?&lt;/a&gt; on Meta Stack Exchange. (I do not recall this issue being discussed on MathOverflow Meta.)&lt;/li&gt;&#xA;&lt;li&gt;Moderators can now edit close reasons listed under the community-specific header. For example, they were recently changed on Mathematics Stack Exchange: &lt;a href=&quot;https://math.meta.stackexchange.com/q/31544&quot;&gt;New changes to close reasons&lt;/a&gt;. Change of a close reasons requires &lt;em&gt;two moderators&lt;/em&gt; as mentioned here: &lt;a href=&quot;https://meta.stackexchange.com/q/346830&quot;&gt;New UI for modifying community-specific close reasons (for moderators) – bugs, feature requests, etc&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;The way closed question are displayed to the OP (list of tips shown to the OP in the modal window and while editing).

Although it's not very clear to me what it's exactly (and doubt about usefulness of a tag used by a single user on a subject that is broader), I think the existence of this tag is harmless. But shouldn't be disguised as top-level tag.&lt;/p&gt;&#xA;&#xA; &lt;hr&gt;&#xA;&#xA;&lt;p&gt;Added: the use of &quot;-theory&quot; seems to make it appear like an well-established field, while I guess it's not the case for &quot;factorization&quot; which deals with some natural factoring problems in ring or semigroup theory. (Of course I consider such a notion as UFD well-established, but it's one specific instance and in any case the tag is not used in questions about UFDs).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;For comparison, a quick view of tags with &quot; -theory&quot; (see &lt;a href=&quot;https://mathoverflow.net/tags&quot;&gt;the list of tags with 'theory'&lt;/a&gt;).

In a few cases the '-theory' might oversell the subject, or denote a not clearly defined subject (for one instance of the latter is &lt;a href=&quot;https://mathoverflow.net/questions/tagged/algebraic-theory&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;algebraic-theory&amp;#39;&quot; rel=&quot;tag&quot;&gt;algebraic-theory&lt;/a&gt;: actually it should be &lt;a href=&quot;https://mathoverflow.net/questions/tagged/algebraic-theories&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;algebraic-theories&amp;#39;&quot; rel=&quot;tag&quot;&gt;algebraic-theories&lt;/a&gt; in such case since the tag is about these theories as mathematical objects, rather than as mathematical field— by the way it seems to be entirely captured by &lt;a href=&quot;https://mathoverflow.net/questions/tagged/universal-algebra&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;universal-algebra&amp;#39;&quot; rel=&quot;tag&quot;&gt;universal-algebra&lt;/a&gt; but this is too much of a digression).

You can see the new synonyms in the &lt;a href=&quot;https://mathoverflow.net/tags/synonyms&quot;&gt;list of tag synonyms&lt;/a&gt; (&lt;a href=&quot;http://web.archive.org/web/20200503175730/https://mathoverflow.net/tags/synonyms&quot; rel=&quot;nofollow noreferrer&quot;&gt;Wayback Machine&lt;/a&gt;). The three tags (abstract-algebra), (geometry) and (discrete-mathematics) were deprecated, you can find links to their original tag-excerpts here: &lt;a href=&quot;https://meta.mathoverflow.net/q/3261&quot;&gt;What is the correct way to handle questions with deprecated tags?&lt;/a&gt;&#xA;There is also some related discussion &lt;a href=&quot;https://chat.stackexchange.com/rooms/10243/conversation/synonyms-for-deprecated-tags&quot;&gt;in MO editor's lounge&lt;/a&gt;. (Possibly you can just &lt;a href=&quot;https://chat.stackexchange.com/rooms/info/10243/mo-editors-lounge?tab=stars&quot;&gt;check the starred messages&lt;/a&gt; if you want to get a brief overview without reading the whole things.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;As far as I can tell, the tags weren't merged when the synonyms were created.&lt;sup&gt;1&lt;/sup&gt; This has the advantage that creation of the synonym can be reversed. (If the tags are merged and synonymized, even after canceling the synonym the question will still have the new tag and there isn't a way to restore the original tags.) If you check &lt;a href=&quot;https://chat.stackexchange.com/transcript/message/54267695#54267695&quot;&gt;some older questions&lt;/a&gt; which originally had those tags, you can still see there (abstract-algebra), (discrete-mathematics) or (geometry). IIRC the tags will remain in this way until the question is edited.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;The fact that the tags are now synonyms means that: &lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;When somebody tries to add the old tag, it is automatically replaced by the new tag. (The same thing happens if a question is edited.)&lt;/li&gt;&#xA;&lt;li&gt;The old tags behave in search as their synonym. (For example, if you click on &lt;a href=&quot;https://mathoverflow.net/questions/tagged/geometry&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;geometry&amp;#39;&quot; rel=&quot;tag&quot;&gt;geometry&lt;/a&gt;, you are shown the posts tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/mg.metric-geometry&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;mg.metric-geometry&amp;#39;&quot; rel=&quot;tag&quot;&gt;mg.metric-geometry&lt;/a&gt;.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;p&gt;Of course, creating the synonym means that some questions do not have appropriate tags. (For example, not every question which was tagged (geometry) is a good fit for (mg.metric-geometry).) However, as the questions still display the original tag, at least we can recognize the &quot;suspect&quot; questions while viewing the question.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It seems that the synonyms were created without discussion here on meta. (I do no know whether the moderators discussed this step among them.) The purpose of this question is to get some input from MathOverflow community on these synonyms. (Since this influenced tags &lt;a href=&quot;https://chat.stackexchange.com/transcript/10243/2020/3/5&quot;&gt;on approximately 700 to 750 questions&lt;/a&gt;, that seem to be quite significant change, the MathOverflow community probably should be aware that this happened.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Main question.&lt;/strong&gt; Should these synonyms remain, or should they be cancelled? Should the tags be merged or not? (And if they are merged, should the deprecated tags be removed or should they remain as a synonym?) If currently merging is not suitable, should they be merged later? Should the tags be blacklisted - to prevent users from adding them to new questions?&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;The moderator who created the tag synonyms &lt;a href=&quot;https://chat.stackexchange.com/transcript/message/54268048#54268048&quot;&gt;mentioned two aspects as advantages of the current state&lt;/a&gt;: &quot;I see two advantages to the current situation with the synonyms: (1) No new uses of the old tag, and automatic retagging on edit.  (2) We can still search out the tag by hand (e.g., using a browser's &quot;find&quot; function on a page full of &lt;a href=&quot;https://mathoverflow.net/questions/tagged/mg.metric-geometry&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;mg.metric-geometry&amp;#39;&quot; rel=&quot;tag&quot;&gt;mg.metric-geometry&lt;/a&gt; questions) and manually change them over time.&quot;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Preventing new questions from using the deprecated tags.&lt;/em&gt; It is true, that with these synonyms in place the deprecated tags are not added to new questions, as they are automatically changed to other tags. One thing to consider is whether this might lead to incorrectly tagged question. (Some people might not noticed that when they entered (geometry), it was converted to (mg.metric-geometry).)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If we want to prevent the tags from being added to new questions, the tags could be blacklisted instead of having a synonyms. This is what I proposed before: &lt;a href=&quot;https://meta.mathoverflow.net/q/3718&quot;&gt;The existing deprecated tags should be blacklisted&lt;/a&gt;. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Changing tags without bumping.&lt;/em&gt; Synonyms have changed which tags are found, for example, when searching for (mg.metric-geometry). (Even the ones which were originally tagged (geometry).) This was done without having to bump any questions. There are also other tools available to mods which can achieve such large-scale changes. For example, if the tag (geometry) is manually cleaned in such way that all questions in this tag fit into (mg.metric-geometry), then the two tags can be merged. (This replaces all instances of one tag by the other one.) Or if the tag (geometry) is in the state where all existing questions would be correctly tagged after omitting this tag, moderators can ask Stack Exchange staff to burninate the tag (which removes all instance of the tag completely). However, both burnination and merging should IMO be done only after the sufficient clean-up of the tag.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;em&gt;Finding the questions with deprecated tags.&lt;/em&gt; As mentioned above, after this change some questions are not tagged correctly and could possibly require further clean-up. However, it is now more difficult to find those posts. (For instance, searching for &lt;a href=&quot;https://mathoverflow.net/questions/tagged/geometry&quot;&gt;posts tagged (geometry)&lt;/a&gt; now returns the posts with the (mg.metric-geometry) tag.) The deprecated tags on those questions are still visible, but they are more difficult to find. (They would be easier to find if the tag synonyms were canceled. As mentioned above, we can still prevent the deprecated tags from being added to new questions using blacklisting.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;It is possible to use &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;various SEDE queries&lt;/a&gt; to search among the questions which have the deprecated tags. For example, &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1190392/find-questions-containing-the-given-tag?tagname=abstract-algebra&quot; rel=&quot;nofollow noreferrer&quot;&gt;this query&lt;/a&gt; returns the questions which have the given tag.&lt;sup&gt;2&lt;/sup&gt; And you can add various further criteria to the query.&lt;sup&gt;3&lt;/sup&gt; (Although it is definitely less comfortable than searching directly on the site. Moreover, the data in SEDE are only updated once a week.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In case it is useful, users who are interested in the tag management could create some list of questions which had the deprecated tags (either on site or off site). I have made a post to show what I mean here: &lt;a href=&quot;https://meta.mathoverflow.net/q/4545&quot;&gt;Recent tag synonyms for deprecated tags&lt;/a&gt;. (The post is visible to &lt;a href=&quot;https://mathoverflow.net/help/privileges/moderator-tools&quot;&gt;10k+ users&lt;/a&gt; and mods. I deleted the question after posting it - I did not want to have two closely related posts on meta after each other. Moreover, if the linked question will be actually used, it could probably get bumped a lot.)&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;Since not everybody is familiar with tag-related actions, let me also briefly summarize some terminology.&lt;/p&gt;&#xA;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;em&gt;&lt;a href=&quot;https://meta.stackexchange.com/tags/tag-synonyms/info&quot;&gt;Tag synonym&lt;/a&gt;.&lt;/em&gt; A synonym (tag1) &lt;span class=&quot;math-container&quot;&gt;$\to$&lt;/span&gt; (tag2) means that the tag (tag1) will be automatically replaced by (tag2) when added to question or when editing a question. And in many other aspects, (tag1) now behaves as (tag2). (For example, searching for (tag1) gives the posts with (tag2).) See also the FAQ post: &lt;a href=&quot;https://meta.stackexchange.com/q/70710&quot;&gt;What are tag synonyms and merged tags? How do they work?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;em&gt;Merging two tags.&lt;/em&gt; Merging should be used carefully, since it is not a reversible process. If a tag (geometry) is merged into (mg.metric-geometry), that means that all instances of (geometry) are changed to (mg.metric-geometry). (Without bumping any questions.) The change is also made in the revision history. (So from the question it will no longer be visible which tag it had before merging.) There is a section &quot;What are merged tags?&quot; in the FAQ post: &lt;a href=&quot;https://meta.stackexchange.com/q/70710&quot;&gt;What are tag synonyms and merged tags? How do they work?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;em&gt;&lt;a href=&quot;https://meta.stackexchange.com/tags/tag-blacklist/info&quot;&gt;Blacklisting a tag&lt;/a&gt;.&lt;/em&gt; Blacklisting prevents the tag from being added to new questions. (And, at the same time, if some question already has the blacklisted tag, it must be changed when the question is edited - an edit which still keeps the blacklisted tag cannot be saved.) I tried to explain the details concerning blacklisting in my previous post: &lt;a href=&quot;https://meta.mathoverflow.net/q/3718&quot;&gt;The existing deprecated tags should be blacklisted&lt;/a&gt;. There is also a FAQ post: &lt;a href=&quot;https://meta.stackexchange.com/q/295148&quot;&gt;What is a blacklisted tag?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;em&gt;&lt;a href=&quot;https://meta.stackexchange.com/tags/tags-burnination/info&quot;&gt;Burnination&lt;/a&gt;&lt;/em&gt; means that all occurrences of the tag are removed from all questions which have the given tag. Again this is done without bumping any questions. Unlike merging, this cannot be done by mods, so a member of Stack Exchange staff has to be involved. See also: &lt;a href=&quot;https://meta.stackexchange.com/q/120640&quot;&gt;What does it mean to “burninate” a tag?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;See also: &lt;a href=&quot;https://math.meta.stackexchange.com/q/11162&quot;&gt;What is the difference between merging two tags and synonymizing two tags?&lt;/a&gt; and &lt;a href=&quot;https://meta.stackexchange.com/q/263956&quot;&gt;What is the difference between a synonym and merging a tag?&lt;/a&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;In SEDE you can see the status when the database was last updated, which was before creating the synonym.

In cases of doubt, you can verify that the newsgroup exists by looking at &lt;a href=&quot;https://admin.gmane.io/&quot; rel=&quot;nofollow noreferrer&quot;&gt;admin.gmane.io&lt;/a&gt; on the web.&lt;/li&gt;&#xA;&lt;li&gt;You should end up back at the &lt;code&gt;*Group*&lt;/code&gt; buffer and the group name is now visible there (and will be there forever, unless you delete it somehow). Put the typing cursor over it and press &lt;code&gt;⏎&lt;/code&gt; to access the newsgroup. You will be asked how many articles you want. I just press &lt;code&gt;⏎&lt;/code&gt; here and get all of them.&lt;/li&gt;&#xA;&lt;li&gt;A new buffer will appear containing the archived posts. You can then search through posts using &lt;code&gt;alt-s&lt;/code&gt; to search forwards and &lt;code&gt;alt-r&lt;/code&gt; to search backwards. You can also filter by author, which is helpful if that information is given (I use the menus to do this). &lt;strong&gt;Unfortunately, I still don't know of any method of getting directly to the archived post from an old &lt;code&gt;permalink.gmane.org&lt;/code&gt; link.&lt;/strong&gt;&lt;/li&gt;&#xA;&lt;li&gt;To access a post, put your typing cursor over it and press &lt;code&gt;⏎&lt;/code&gt;. A new buffer containing the post will then fill most of the lower part of the Emacs window, and you can change your typing cursor back and forth between the post's buffer and the mailing list's buffer using &lt;code&gt;ctrl-x o&lt;/code&gt; or the mouse, as you would normally in Emacs.&lt;/li&gt;&#xA;&lt;li&gt;You can copy text using &lt;code&gt;ctrl-space&lt;/code&gt;, moving the typing cursor, then &lt;code&gt;alt-w&lt;/code&gt; as you would normally in Emacs. In general everything you have in Emacs works as usual, &lt;em&gt;e.g.&lt;/em&gt; creating files, pasting text into them, using &lt;code&gt;ctrl-x b&lt;/code&gt; to change between buffers and so on.&lt;/li&gt;&#xA;&lt;li&gt;Sometimes Gnus will just hang up for no apparent reason while retrieving a post or searching.

A question is added there if there is a link between the two questions somewhere on the page. (I.e., in questions, answers, comments. The &quot;linked relation&quot; is symmetric.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, when this feature was introduced, the sidebar was not updated for already existing questions.&lt;sup&gt;1&lt;/sup&gt; This is more prominent on MathOverflow than on the other sites - as far as can tell, this feature works on MO only since it joined the Stack Exchange network.&lt;sup&gt;2&lt;/sup&gt; Before that, MO was running on an older version of SE software. So you can find plenty of posts (the ones made in the first half of 2013 and before) which link to some other post, but that post is not shown in the list of linked questions.&lt;sup&gt;3&lt;/sup&gt;&lt;/p&gt;&#xA;&#xA;&lt;p&gt;In my opinion, showing linked questions is a useful feature - if somebody is looking at some question (for example, after they were searching for posts concerning a certain problem or a specific topic), they see some other questions which might be of interest, too. (Other posts which are related to this one are likely to be mentioned at least in comments or possibly in the question or in the answers. Still, the list of linked questions gives a prominent place where related topics are collected.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Moreover, the number of linked questions influences what is displayed &lt;a href=&quot;https://meta.stackexchange.com/questions/172726/whats-the-frequent-sort-function&quot;&gt;in the frequent tab&lt;/a&gt; of some tag. So including links from older posts might help with this aspect, too. (Common questions being listed in the frequent tab might be useful when searching among the questions in some specific tag.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;&lt;strong&gt;Proposal:&lt;/strong&gt; Add the sidebar with the linked questions also for links which were posted before MO moved to Stack Exchange 2.0 software.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Occasionally, I have tried to add the missing links &lt;em&gt;manually&lt;/em&gt;. &lt;sup&gt;4&lt;/sup&gt; There is some advantage to that - one can judge whether or not the link is actually useful  and include it only if it adds something useful to the question. However, this is rather cumbersome and it would be better if this was, in some way, automated.&lt;/p&gt;&#xA;&#xA;&lt;hr&gt;&#xA;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt; This was introduced in April 2010, see: &lt;a href=&quot;https://meta.stackexchange.com/q/48076&quot;&gt;Whoa!

Then I add a comment on Q1 containing link to Q2. After this, Q2 is added to the list of linked posts. And it remains even if I remove the comment a bit later.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;However, this does not work if link to Q2 is given in &lt;em&gt;comments&lt;/em&gt; rather then in the question (or in one of the answers).&lt;/p&gt;&#xA;&#xA;&lt;p&gt;You can find some of the posts where I added the link in this way in MO editors' lounge: &lt;a href=&quot;https://chat.stackexchange.com/search?q=%22tagged%2Flinked-questions%22&amp;amp;room=10243&quot;&gt;https://chat.stackexchange.com/search?q=%22tagged%2Flinked-questions%22&amp;amp;room=10243&lt;/a&gt;&#xA;&lt;a href=&quot;https://chat.stackexchange.com/search?q=linked&amp;amp;room=10243&quot;&gt;https://chat.stackexchange.com/search?q=linked&amp;amp;room=10243&lt;/a&gt;&#xA;&lt;a href=&quot;https://chat.stackexchange.com/search?q=temporary&amp;amp;room=10243&quot;&gt;https://chat.stackexchange.com/search?q=temporary&amp;amp;room=10243&lt;/a&gt;&#xA;I have saved one example in Wayback Machine - in order to be able to show it here.

No, the OP did not ask for that migration; it was someone else who raised the flag. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;(At the time I was taking a little but much needed break from my usual level of moderator activity, and told my fellow moderators I was doing so. So one of them stepped up in this instance.) &lt;/p&gt;&#xA;&#xA;&lt;p&gt;As noted in another answer by an HSM mod, the post was sent back, and has now been reopened by five regular MO users within the last few hours. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;There is no easy way to answer &quot;why are some questions migrated to HSM and others not?&quot;. As is so often the case, how to process a flag is left to the discretion of individual moderators; it's not like we usually have meetings over how to process a flag, unless the situation seems particularly sticky. So, it was a judgment call (and I can't speak for the moderator who made that call). I recall that some years back I had migrated a question over there, mostly in the belief that it was more appropriate there, but partly also because I wanted to support the HSM community. It saddens me a little that it never took off more. In fact, I have a question sitting over there now that should probably be migrated over here, or cross-posted since some time has elapsed. &lt;/p&gt;&#xA;&#xA;&lt;p&gt;So, it may be true that history of mathematics questions generally get a better reception at MO than at HSM.

Not being active on the mathematics forum, I will give my belief, which hopefully matches the intent, of the community for that forum.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;MathOverflow has a community of professional mathematicians employed in academia and industry, graduates and undergraduates who wish to learn at a deep level the work the professionals discuss, and other professional and nonprofessionals who are similarly inclined. This community (specifically those who are doing graduate level study) is at or near the forefront of the body of mathematical knowledge, trying to increase it.  Their goal is to discuss things at this forefront.  In particular, they normally don't do homework problems, unless it is closely related or extendable to their work.  They also share references, so that members can educate themselves enough to get close to the forefront.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;I believe mathematics.stackexchange has a wider variety of members, including many from MathOverflow.  Here the focus is not on the professional frontier, but on topics and areas of wider interest.  Perhaps this includes a competition problem, or a new twist on a problem regularly taught in classes.  Sometimes a standard problem is discussed, to reveal a way of thinking that prevents people from seeing a solution, and how to change that to make the solution more apparent.  The members here are interested in exploring mathematics at many levels, not just professional.  However, solving routine homework problems or reviewing old contest problems is not part of the intent.  The community is looking for new and interesting mathematical topics.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Both communities are willing to help new members if it looks like the new member will fit in and help further the forum mission and serve the interests of that community.  If it looks like that won't happen, they won't devote the time.  As a result, one should find a way to contribute well from the start. Most often this is to provide a good answer, but sometimes one can start with a good question.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;What makes an answer or a question good? That such a post serves the community interests.  For MathOverflow, this is a well written post that normally talks about a specific topic in the forefront and asks an accessible mathematics question or gives an accessible answer to such. (There are some exceptions such as big list questions, which I won't discuss here.) For the other forum, it is a well written question or answer that makes a community member feel their time was worth spending in reading and thinking about it, usually because they learn something from it.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;To answer your questions, read the fora and see which posts are well received, and try to imitate those.  Use the meta to vet your first or your challenging post to see if it fits community norms and will be seen as a positive contribution.

Many of the clientele are professional researchers (or soon to be professional) who have learned enough of the craft of research that most would not think of asking any question about the process itself on this forum.  They see MathOverflow as a research tool for their specific focussed question. (They may see MathOverflow in other ways too, but usually research is so core to their existence that the word research itself seems redundant, or like excess baggage; they see no need for the tag.)&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Many of the clientele are people who want to move toward research in mathematics.  They may not be professional mathematicians, but they have or see the need for mathematics at more depth than appears at an everyday level. Some of these clientele are researchers in a different profession, and may not be familiar with the characteristics involved in conducting and presenting research in mathematics.  They may have questions about how to do this. I can think of  no other forum (not even Academia.stackexchange) equipped to handle such questions.  For example, what is a good way to set up an Atlas of relational structures for use by mathematicians in other fields, especially if (for some unknown reason) one restricts relations to be ternary or of higher arity? Such a query on Academia would quickly be migrated here, or at least the migration would be attempted.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;There are (I believe) clientele of this forum  outside of those two categories. (I know at least one such member.) They may not be adept at research, or at their field of study, or even at posing well crafted questions for MathOverflow.  They still can contribute something, and they may have enlightening questions having to do with the process of research.  I think an appropriate question for this forum would be how to determine what work is publishable where.  In particular, if you have a result and you are doing a literature search, how do you announce it and get help on the search to determine how novel the result is?  Let me ask this general question on MathOverflow.  Gee, what tag should I use?&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Finally, there is the non posting clientele. They may not ask any questions or make posts of any kind.  However, they use this body of knowledge regularly to answer questions.  If some of the questions pertain to describing the process, they may deserve a research tag.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;If you want to fragment the tag into specific pieces of the process, that might be a good idea. (It might be a bad idea.). If you want to remake the tag to emphasize that this forum is about mathematics, go ahead and call it mathematical-research.  I think removing the tag will do a disservice to all but the first set of clientele described above.&lt;/p&gt;&#xA;&#xA;&lt;p&gt;Gerhard &quot;In A Class By Himself?&quot; Paseman, 2020.06.13.&lt;/p&gt;&#xA;" OwnerUserId="3402" LastActivityDate="2020-06-13T16:12:12.847" CommentCount="2" ContentLicense="CC BY-SA 4.0" />

(Pointers to more detailed information about burnination can be found in the &lt;a href=&quot;https://meta.stackexchange.com/tags/tags-burnination/info&quot;&gt;tag-info on Meta Stack Exchange&lt;/a&gt;. I have also included a short explanation concerning burnination and also some other terminology related to tag management in this post: &lt;a href=&quot;https://meta.mathoverflow.net/q/4551&quot;&gt;What to do with the synonyms for the deprecated tags?&lt;/a&gt;.)&lt;/p&gt;&#xA;&lt;p&gt;Some additional remarks:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;It is true that the tag could be removed manually. It would take approximately one week, if done by one user while respecting the guideline to &lt;a href=&quot;https://meta.mathoverflow.net/questions/599/do-we-have-an-unofficial-quota-on-how-many-old-questions-one-should-bump-for-min/604#604&quot;&gt;bump at most three old posts per day&lt;/a&gt;. Still, burnination might have some minor advantages.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;On MathOverflow, the moderators sometimes use merging into &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot;&gt;tag-removed&lt;/a&gt;, which can be seen as &amp;quot;poor man's burnination&amp;quot;. The disadvantage of this approach is that the the &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot;&gt;tag-removed&lt;/a&gt; tag still remains there as an artifact. (And it is supposed to be removed manually at some point, at least if the questions gets bumped for some other reason. See also: &lt;a href=&quot;https://meta.mathoverflow.net/q/657&quot;&gt;'Tag-removed' tags where they possibly shouldn't be&lt;/a&gt; and &lt;a href=&quot;https://meta.stackexchange.com/q/309327&quot;&gt;Burnination vs. merging into a specific tag&lt;/a&gt;.) It would be different if all questions tagged research would fit, for example, the &lt;a href=&quot;https://mathoverflow.net/questions/tagged/advice&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;advice&amp;#39;&quot; rel=&quot;tag&quot;&gt;advice&lt;/a&gt; tag. Then the moderators could merge &lt;a href=&quot;https://mathoverflow.net/questions/tagged/research&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;research&amp;#39;&quot; rel=&quot;tag&quot;&gt;research&lt;/a&gt; into &lt;a href=&quot;https://mathoverflow.net/questions/tagged/advice&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;advice&amp;#39;&quot; rel=&quot;tag&quot;&gt;advice&lt;/a&gt;, and all instances of the tag would be replaced without any bumping. (And without adding an artificial tag which still has to be removed - as in the case of &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot;&gt;tag-removed&lt;/a&gt;.)&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;One disadvantage is that burnination cannot be done by moderators and requires somebody from Stack Exchange staff. On the other hand, this gives the MO mods an opportunity to test the new escalation process. Of course, it is up to the moderators' judgement to decide whether this post is suitable for escalation. The new tag &lt;a href=&quot;/questions/tagged/status-review&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;status-review&amp;#39;&quot; rel=&quot;tag&quot;&gt;status-review&lt;/a&gt; was recently introduced, it gives moderators of Stack Exchange sites a simple way to get various issues raised local metas to the attention of CMs and Stack Exchange employees.

This new workflow was introduced relatively recently - in March 2020. So far, the tag has been added on this meta &lt;a href=&quot;https://data.stackexchange.com/meta.mathoverflow/query/1105163/questions-which-had-the-given-tag-including-the-editor-who-added-it?tagname=status-review&quot; rel=&quot;nofollow noreferrer&quot;&gt;only by Stack Exchange employees&lt;/a&gt;.

I believe that a community wiki question on MO about a person's mathematical achievements and/or legacy is, generally speaking, an appropriate and and actively positive use of the forum.  My arguments, in no particular order:&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Consistent with MO mission&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Reviewing a successful mathematician's contributions is by definition research-focused, and it often gives an interesting glimpse into connections between the different ideas that the person worked on.

MO should of course heed the wishes of surviving friends and family one way or the other, but a priori I don't think that it is disrespectful or exploitative to acknowledge and celebrate someone's contributions on the internet.  Caution should be exercised in cases where the mathematician had a rocky or controversial relationship with the mathematical community, but I think the risk is low in most cases.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;The risks are low&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;So far as I am aware there is no explicit rule against these sorts of questions currently, so if there were a high risk that they would be abusive or disrespectful (or perceived as such) then we would probably know about it by now.&lt;/p&gt;&#xA;" OwnerUserId="4362" LastActivityDate="2020-07-12T20:00:36.897" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

The OP asks whether this question (which can be viewed at Mathematics) can be asked here, again. (There are two questions that OP asked at MO main that concern the function the OP is interested in, which appears in a paper of Connes, but these questions were closed and deleted.)&lt;/p&gt;&#xA;&lt;p&gt;First, there is a question ban which we moderators don't have control over: this is due to a Stack Exchange algorithm running in the background. So for the time being, no, this or any question can't be asked until the question ban is lifted by the software. I don't know when that might be. But generally speaking the time period can be shortened by doing good things for the community such as giving good answers to questions.&lt;/p&gt;&#xA;&lt;p&gt;Then the question becomes: can OP ask the question once the ban is lifted? Answer: the community will look upon it poorly if the OP tries to re-ask a question that was closed and deleted. In fact, question repetition is considered a site violation, and could incur a penalty such as an account suspension, especially if the OP has been made aware of policy and chooses to ignore it anyway. Instead of repeating a question that was closed, what should be done is improve the question that was closed. (But see the advice given below.) Particularly, the OP can undelete the self-deleted question Possible New way to prime number theorem: [sic], and then edit it in the hope that the community votes to re-open the question.&lt;/p&gt;&#xA;&lt;p&gt;So far what I've done is recite site policy. As a practical matter, getting the community to re-open a closed question is not always easy. My impression is that the question as it currently stands (which asked &amp;quot;Is there any way we can prove prime number theorem using above series ?&amp;quot; [sic]) was not well-researched by the OP and is vague, open-ended. This type of question is not a good MO question. It would be close to impossible to prove that the PNT &lt;em&gt;can't&lt;/em&gt; be proved using Connes' function, because one doesn't have access to the space of all possible proofs; on the other hand no reason is given for suspecting such a proof exists, even in outline form. To me it looks like not much more than a vague hope.&lt;/p&gt;&#xA;&lt;p&gt;If the OP were to provide compelling reasons for why he/she thinks such a proof is in the offing, then it could be a different story. But I think that would require intensive research and investigation from the OP beforehand, before it gets to that stage. That's how it usually is at MO.&lt;/p&gt;&#xA;&lt;p&gt;I have looked over some of the discussion and comments both here and at Mathematics Stack Exchange. The OP says he/she is just barely older than a teenager. In view of this, I am going to offer some unsolicited advice, with no disrespect intended. It's this: don't edit a question over and over and over in the hope it will one day be accepted. A well-crafted question is something thought over and worked out in advance, and usually reflects prior experience and immersion in the subject matter; normally, it will require little to no revision once it has been posted. If it requires many revisions, then it wasn't a well-crafted question to begin with. If you carry out many revisions, then it will likely become annoying to others as the question is repeatedly bumped in the effort to straighten it out.&lt;/p&gt;&#xA;&lt;p&gt;My advice to young people who are relatively new to research is: don't be in a hurry or ambitious to get a question accepted at MO. As an end, it's not important. What is important is to let a question ripen and mature through the hard work you have put into it.&lt;/p&gt;&#xA;&lt;p&gt;Look around at other well-received questions in the areas that interest you. Often times it will be the case that the OP just needed a nudge in the right direction because the OP's mind has been properly prepared through all the effort made in advance. On the other hand, I see hundreds and hundreds of questions coming from people who haven't put in the necessary work. Usually the answers will be wasted on them because they're not ready to receive the message, and they may founder for years this way, wasting time. Think hard, go deep, and then the questions proper for MO may emerge naturally.&lt;/p&gt;&#xA;" OwnerUserId="2926" LastActivityDate="2020-07-16T23:31:24.117" CommentCount="2" ContentLicense="CC BY-SA 4.0" />

Is there any way to trigger this behaviour when it doesn't happen automatically?&lt;/p&gt;&#xA;&lt;p&gt;(One situation where the question title &lt;em&gt;isn't&lt;/em&gt; auto-expanded appears to be cross-SE links:  &lt;a href=&quot;https://physics.stackexchange.com/questions/552396/fluid-dynamics-for-the-sepiolite&quot;&gt;https://physics.stackexchange.com/questions/552396/fluid-dynamics-for-the-sepiolite&lt;/a&gt; ; but I'm sure, although I can't dig up an example, that I've also seen it not being auto-expanded even on links within MO.)&lt;/p&gt;&#xA;&lt;p&gt;EDIT:  @GerhardPaseman's &lt;a href=&quot;https://meta.mathoverflow.net/questions/4653/when-are-question-titles-auto-expanded#comment23591_4653&quot;&gt;suggestion&lt;/a&gt;:  &lt;a href=&quot;https://mathoverflow.net/q/243490&quot;&gt;How do these primes jump?&lt;/a&gt; .

Martin Hairer (chair of the ICM programme committee) asked a question about proposed topics for an ICM special lecture.  David's answer started with, &amp;quot;A topic worthy of a special lecture, and with no obvious other place to go, is ways we as mathematicians can make our field more diverse, equitable, and inclusive.&amp;quot;&lt;/p&gt;&#xA;&lt;p&gt;Your comment starts as an objection to the claim that the topic has no obvious other place to go.  David has clarified that he meant this in the context of lectures at the ICM, but let's assume this interpretation was not clear.  Your response was roughly that diversity is a widely-discussed topic in academia, or perhaps that there are already substantial efforts to increase diversity in academia.  Okay, but how is that a dissenting viewpoint?  You were only addressing a peripheral point in the first sentence, and you didn't come to any conclusion about the core of David's answer.&lt;/p&gt;&#xA;&lt;p&gt;What would your dissenting viewpoint be if you chose to write one explicitly?&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&amp;quot;I don't think this topic has a place in the ICM because people discuss it everywhere else&amp;quot;?&lt;/li&gt;&#xA;&lt;li&gt;&amp;quot;This topic is not worthy of a special lecture because I like my ICMs to be research-only/non-political/devoid of discussion about social aspects of our field&amp;quot;?&lt;/li&gt;&#xA;&lt;li&gt;&amp;quot;I disagree with the idea that we as mathematicians should try to make our field more diverse, equitable, and inclusive&amp;quot;?&lt;/li&gt;&#xA;&lt;li&gt;Something else?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;To return to the point of your question, it seems that someone who may have read between the lines of your comment chose to flag it as &amp;quot;harassment, bigotry, or abuse&amp;quot; and a moderator then responded by deleting it.

For a site like this that depends a lot on community moderation, we can then ask: does the community have the skills to resolve these disputes?  Right now the rules are tuned so that only two types of disputes can occur:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;Mathematical disputes: Can X prove Y? Does a thing with property Z exist? etc.&lt;/li&gt;&#xA;&lt;li&gt;Scoping disputes: Is this a question about mathematics?  Is it a research question, or standard knowledge in the field?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;The skillset the community needs in order to resolve these disputes is that of a mathematical researcher, and we have those in abundance.  I'm sure it doesn't always go perfectly, but there's an additional layer of moderators who also have the training to deal with these sorts of issues.&lt;/p&gt;&#xA;&lt;p&gt;If we allow questions and answers related to politics - academic or otherwise - then we're introducing a source of controversy that we do not, as a community, have the expertise and experience to deal with.  A great many people here probably have &lt;em&gt;informed opinions&lt;/em&gt; about how universities and math departments are run and so forth, but this is different from serious expertise in academic administration.  (Unless there are a lot more academic administrators lurking around here than I realize.)  Of course the same goes for even more controversial political matters about which we have even less built-in expertise.&lt;/p&gt;&#xA;&lt;p&gt;So if we do want to allow this stuff, we'll either need a plan for how we will expand the community so that we have a critical mass of participants with the right skillset, or some other plan for how we will maintain high moderation standards.

The clear case is when one can &lt;em&gt;answer&lt;/em&gt; a question. The regular practice of picking up a question that is accessible, answering it, and communicating the answer can be very beneficial. Even I am learning from it a lot and I'm by no means new to &amp;quot;random problem solving&amp;quot;. So, if a student (or anybody in general) can answer questions on MO, I would definitely encourage them to participate. Just warn them that it may become addictive, so they should balance it with their regular duties. I have also never seen any &amp;quot;unwelcoming behavior&amp;quot; with respect to people who post answers, at least, as long as purely mathematical discussions are concerned.&lt;/p&gt;&#xA;&lt;p&gt;The issue arises when somebody's contribution is reduced to asking endless questions of the type &amp;quot;I cannot figure out this place in the textbook, can you help me?&amp;quot;. There &lt;em&gt;are&lt;/em&gt; questions of this type that are still eligible for MO, but many of them are on the borderline and would be better redirected to MSE or just to the student adviser. So, I would suggest that in such cases the students view MO as the last resort, not as a help hotline.&lt;/p&gt;&#xA;&lt;p&gt;Any questions about student research (i.e., something that is not readily found in the textbooks or, if you prefer, something that falls under the &amp;quot;missing-lemma&amp;quot; tag) have always been welcome and I try to answer them and to protect them from closing as much as I can even if they look a bit &amp;quot;homeworkish&amp;quot;. I would encourage such questions any time. Some of them are now being asked on MSE, which is a pity, because they usually just get flushed by the stream there unless somebody attaches a bounty.&lt;/p&gt;&#xA;&lt;p&gt;As to &amp;quot;MO being less friendly to newcomers&amp;quot;, my feelings are mixed. On the one hand, we introduced a lot of friendly perks like the automated reminder to (try to) be nice whenever responding to someone who posts for the first time. On the other hand, there still seems to be a strong movement to eradicate everything that is not &amp;quot;research-looking&amp;quot; when judging from pure appearance (though I would say it was much stronger a year or two ago). I mean such things as, for instance, voting to close for &amp;quot;the lack of motivation&amp;quot;. My own stance is that any clearly posed mathematical problem that I cannot solve in under 10 minutes should pass and the OP has no obligation to explain in detail where it came from and what it is related to. It especially applies if the OP is a student: quite a few of them have enough trouble with merely understanding and stating what exactly they need.&lt;/p&gt;&#xA;&lt;p&gt;The MO may be not exactly what it was 10 years ago (all is changing, all is flowing, and some part of the discrepancy in perception may come from the fact that we ourselves are not exactly what we were 10 years ago), but it still looks like a nice and interesting place to be at to me. As soon as the student is ready for a mathematical discussion, he or she is welcome to enter. That may happen at any &amp;quot;stage of PhD&amp;quot; and at any age. I wouldn't be surprised to learn if some participants of MSE who ask there questions that might be suitable for MO as well are, in fact, high school teenagers or undergraduates. If in doubt, just try MSE first, but if you see that your questions merely earn you reputation there but are left unanswered, switch to MO.&lt;/p&gt;&#xA;&lt;p&gt;Those are just my two cents, but I'm an old-timer.

And the memorial questions I have seen are generally of this form.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;[However, contra the last point, these kind of &amp;quot;math tea&amp;quot; discussions are often among the most highly upvoted things on MO: both the questions and answers.]&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;Every year, many great mathematicians sadly pass away. Thus if memorial questions become routine, there will inevitably be a continuous stream of these questions. So, even if you think a handful of borderline/&amp;quot;chatty&amp;quot; questions are ok for MO, you might be uncomfortable with increasing the volume to this degree.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;I can envision problems with &amp;quot;where to draw the line&amp;quot; in terms of who &amp;quot;deserves&amp;quot; memorialization. On the one hand, it could be uncomfortable/awkward if a question is asked about someone for which there's little to say about their mathematics. On the other hand, if these kind of questions do become very routine, then it might be considered a slight to not have one asked about any given recently deceased mathematician.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;" OwnerUserId="25028" LastActivityDate="2020-09-14T00:27:41.480" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

However, I have a couple reservations with your proposal.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;First, in my opinion &amp;quot;arithmetic logic&amp;quot; is not an ideal tag name: it sounds like it refers to the study of general logics from an &amp;quot;arithmetic&amp;quot; perspective, rather than the study of theories of arithmetic in (usually) classical first-order logic. This is especially true given the term &amp;quot;algebraic logic,&amp;quot; which &lt;em&gt;does&lt;/em&gt; refer to the study of general logics from an algebraic perspective.&lt;/p&gt;&#xA;&lt;p&gt;I think a better tag name would be &lt;strong&gt;&amp;quot;theories of arithmetic.&amp;quot;&lt;/strong&gt; This doesn't give a false impression, is a phrase used frequently within logic, and as far as I know has no other usage within mathematics. It would also cover models of (theories of) arithmetic, since that amounts to the semantic &lt;em&gt;aspect of&lt;/em&gt; the study of theories of arithmetic.&lt;/p&gt;&#xA;&lt;p&gt;(&amp;quot;Arithmetic model theory&amp;quot; would also be a plausible candidate, but I like it less: it suffers from the same false impression drawback, given &lt;span class=&quot;math-container&quot;&gt;$(i)$&lt;/span&gt; the interactions between model theory and number theory, as opposed to theories of arithmetic, and &lt;span class=&quot;math-container&quot;&gt;$(ii)$&lt;/span&gt; terms like &amp;quot;geometric stability theory&amp;quot; for which the corresponding impression is &lt;em&gt;accurate&lt;/em&gt;.)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Second, I don't really think that the examples &amp;quot;Is being rational ...&amp;quot; and &amp;quot;Are surjectivity ...&amp;quot; should be included: they're not about theories of arithmetic, but rather &lt;em&gt;computability-theoretic aspects&lt;/em&gt; of arithmetic. I would use as a criterion that in order to get this tag, a question should somehow be about sets of sentences, in some appropriate logic, which describe the natural numbers. While questions about computability-theoretic aspects can of course be rephrased in such a form, that's not how they're &lt;em&gt;naturally&lt;/em&gt; posed, so I don't think they should count.&lt;/p&gt;&#xA;" OwnerUserId="8133" LastEditorUserId="8133" LastEditDate="2020-10-11T01:29:08.797" LastActivityDate="2020-10-11T01:29:08.797" CommentCount="10" ContentLicense="CC BY-SA 4.0" />

(Which was bumped not too long ago. The linked discussion mostly focuses around the fact that from the &amp;quot;share&amp;quot; button you get the link which can also identify the user copying the link and the possibilities how to get URL without the uid were discussed there.)&lt;/p&gt;&#xA;&lt;p&gt;So I'll summarize a few things here. (To some extent, I am just repeating stuff already said in the answers to this post on Mathematics Meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/3586&quot;&gt;Distinguishing between questions and answers in references.&lt;/a&gt; The post is linked in the comments - but perhaps it is better if this information is posted as an answer, where it is easier to notice.)&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;strong&gt;Various formats of a link to an answer&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;On MO (and other SO sites) there are many possibilities how a working link to the answer can be formed. Let us mention at least the main two:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The format &lt;code&gt;site/a/id&lt;/code&gt; or &lt;code&gt;site/a/id/uid&lt;/code&gt; - where id is the id of the answer. And if you copy the link from the share field, you will get also  For example the link to this answer is: &lt;code&gt;https://meta.mathoverflow.net/a/4749&lt;/code&gt; &lt;a href=&quot;https://meta.mathoverflow.net/a/4749&quot;&gt;https://meta.mathoverflow.net/a/4749&lt;/a&gt; or, if I get the link from the &amp;quot;share&amp;quot; it will contain my uid and it will be: &lt;code&gt;https://meta.mathoverflow.net/a/4749/8250&lt;/code&gt; &lt;a href=&quot;https://meta.mathoverflow.net/a/4749/8250&quot;&gt;https://meta.mathoverflow.net/a/4749/8250&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;You can get the link in the format &lt;code&gt;https://meta.mathoverflow.net/questions/1885/how-do-i-link-to-a-mo-answer/4749#4749&lt;/code&gt; &lt;a href=&quot;https://meta.mathoverflow.net/questions/1885/how-do-i-link-to-a-mo-answer/4749#4749&quot;&gt;How do I link to a MO answer?&lt;/a&gt; - basically it contains &lt;code&gt;site/questions/qid/title/aid#aid&lt;/code&gt;. (So the id of the answer is used there as a &lt;a href=&quot;https://en.wikipedia.org/wiki/HTML_anchor&quot; rel=&quot;nofollow noreferrer&quot;&gt;HTML anchor&lt;/a&gt;.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;strong&gt;How to get link to the answer?&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Of course, one possible way is clicking on &amp;quot;share&amp;quot;. And if you don't want uid, you can edit it out manually. (This is a bit cumbersome.)&lt;/li&gt;&#xA;&lt;li&gt;If you're after a link without uid, you can simply browse MathOverflow without being logged in or in incognito mode. (Again, to me this seems a bit cumbersome - but maybe that's a matter of personal teste.)&lt;/li&gt;&#xA;&lt;li&gt;Often it is easier to copy the URL from the browser's address bar. But to do that, you have to get an answer-link into the address bar in some way. There are various ways to do that.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;strong&gt;How to get the answer link into the address bar&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;I consider as a rather fast way simply using the share link to get in your browser to the answer. This might be dependent on your browser, OS and your setup but, for example, this works for me: Ctrl+left click on &amp;quot;share&amp;quot; opens the link in new tab, where I get in the address bar the URL of the answer. The same thing happens if you use right click and then choose &amp;quot;open in new tab/window&amp;quot;. Similarly, I can right click and choose &amp;quot;Copy link address&amp;quot;. This gives me link with my user id - which I don't want - but if I paste the link into the address bar in a new tab or a new window, the browser will be redirected to the page with the &amp;quot;longer&amp;quot; URL fro the answer.&lt;/li&gt;&#xA;&lt;li&gt;Of course, anything where you can find a link to an answer and you can click on it works - another answer mentions that the answer is linked from the OP's profile. (However, the method I describe in the first bullet point has the advantage that I have the share link immediately here whenever I am viewing an answer.)&lt;/li&gt;&#xA;&lt;li&gt;If the answer you're interested happens to be the one that has the most recent activity, you can get to the answer simply by clicking the timestamp saying &amp;quot;active: date&amp;quot; at the top of the page displaying the question.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;In &lt;a href=&quot;https://math.meta.stackexchange.com/questions/3586/distinguishing-between-questions-and-answers-in-references/30814#30814&quot;&gt;my answer on Mathematics Meta&lt;/a&gt; I describe also the shortened format &lt;code&gt;site/q/qid#aid&lt;/code&gt;. for example, for this answer it is: &lt;code&gt;https://meta.mathoverflow.net/q/1885#4749&lt;/code&gt; &lt;a href=&quot;https://meta.mathoverflow.net/q/1885#4749&quot;&gt;https://meta.mathoverflow.net/q/1885#4749&lt;/a&gt;. And I give there also a link to a bookmarklet which can be used to obtain such links which are nicely formatted. (For example, for this answer you get &lt;code&gt;[How do I link to a MO answer?](https://meta.mathoverflow.net/q/1885#4749)&lt;/code&gt; from that bookmarklet. Which is nicely formatted if you paste this into a post or into a comment: &lt;a href=&quot;https://meta.mathoverflow.net/q/1885#4749&quot;&gt;How do I link to a MO answer?&lt;/a&gt;) However, this is probably relevant mainly for writing comments - in which you have rather limited number of characters and it helps a lot if you can shorten the link.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2020-11-01T15:55:44.090" LastActivityDate="2020-11-01T15:55:44.090" CommentCount="1" ContentLicense="CC BY-SA 4.0" />

From my observation so far, the majority the posts appearing and which are (explicitly or in disguise) reviewing requests, are asking if some bunch of computation can be a useful approach, or even a proof, to the Riemann hypothesis, Collatz conjecture, factorization of large integers, etc. In remaining cases, these are often long disorganized sequences of ideas and computations, more or less hard to decipher.&lt;/p&gt;&#xA;&lt;p&gt;Hence, a site which would do this without strict moderation would be overwhelmed with low-quality requests (and hence not very attractive to the research community).

This would be a place visible to the first-time askers. On the other hand, while the how-to-ask page existed, it does not seem to make much difference on the sites it was actually used.

It gained some support from the local community - judging from the comments and upvotes - but not enough to persuade the MathOverflow moderators. That feature request is now moot, since the /aks/advice page is no longer used in the network. Possibly something similar to the text proposed there could be considered - but we would need to shorten it a bit, since here we have less space.&lt;/sup&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;Here is another older post which is - to some extent - related: &lt;a href=&quot;https://meta.mathoverflow.net/q/2142&quot;&gt;Why is “what is the difference between mathoverflow and math.stackexchange?” not prominently displayed?&lt;/a&gt;&lt;/sup&gt;&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Similar discussions I was able to find on other per-site-metas:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://codereview.meta.stackexchange.com/q/10483&quot;&gt;Let's update the modal for new askers&lt;/a&gt; on Code Review Meta.&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://rpg.meta.stackexchange.com/q/9822&quot;&gt;New ask page: How do we want to use it to help new users specify their system?&lt;/a&gt; on Role-playing Games Meta.&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://physics.meta.stackexchange.com/q/12751&quot;&gt;Suggestions for the Welcome Modal&lt;/a&gt; on Physics Meta.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;(I found also these, but they are not specifically about the modal window: &lt;a href=&quot;https://scifi.meta.stackexchange.com/q/12936&quot;&gt;How should SFF's “Ask Question” page be customised?&lt;/a&gt;, &lt;a href=&quot;https://movies.meta.stackexchange.com/q/4640&quot;&gt;How should M&amp;amp;TV's “Ask Question” page be customised?&lt;/a&gt;, &lt;a href=&quot;https://meta.askubuntu.com/q/18979&quot;&gt;Use of new screening tool from SE&lt;/a&gt;.)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Here is a screenshot showing this modal window on MathOverflow:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/C9Z5Q.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/C9Z5Q.png&quot; alt=&quot;screenshot - MO&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;For comparison, this is what you get on Mathematics:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/Tknmd.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/Tknmd.png&quot; alt=&quot;screenshot - Math&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="28104" LastEditDate="2021-12-22T15:59:18.167" LastActivityDate="2021-12-22T15:59:18.167" Title="Customize the modal window for the first-time askers" Tags="|discussion|feature-request|status-completed|asking-questions|new-users|" AnswerCount="4" CommentCount="11" ClosedDate="2021-06-17T16:13:34.093" ContentLicense="CC BY-SA 4.0" />

Obviously any actual change in policy will need to be discussed openly here.&lt;/p&gt;&#xA;&lt;p&gt;Anecdotally, it seems that there is a substantial class of potentially valuable contributors who feel that the basic framework of MathOverflow is unwelcoming.  Whether or not you agree with that, it seems suboptimal to force them to use the same framework for even the earliest stages of a discussion of their concerns.&lt;/p&gt;&#xA;&lt;p&gt;[UPDATE] Let me amplify my thinking a little.  I am guessing that the mooted discussions mostly arise from concerns about gender balance.  It is undeniable that among users of MathOverflow, there are only a tiny minority who are women using their real names.  There may be a few more pseudonymous women, but nonetheless it is clear that the proportion of women on MathOverflow is far below the proportion of women in academic mathematics.  I find this disappointing; there are certainly very many women whose expertise and insight would be extremely valuable if they chose to participate.  I have not seen an explanation of this phenomenon that seems compatible with easily obtainable data.&lt;/p&gt;&#xA;&lt;p&gt;Of course, we should consider explanations like &amp;quot;women do not regard MO as a productive use of their time, and they are correct in this judgement&amp;quot;.  While this should not be rejected out of hand, it would be strange to have a huge gender imbalance in judgements about the value of MO activity, and this would itself seem to need explanation.  Often I see people suggesting that women are unwilling to participate in some kind of forum because they suspect that they will be harassed, or their qualifications belittled and their opinions ignored.  I have tried to search for instances of this sort of thing on MO, and have found very few.  In cases where women do participate using their real names, it seems to me that interactions are very normal, with other users being respectful and appreciative to experts, and helpful to novices.  Certainly I see MO as being much more friendly to women than Twitter, despite the fact that women are far more common there.&lt;/p&gt;&#xA;&lt;p&gt;This situation seems quite mysterious to me.  I think that it is valuable to seek insight and suggestions from as many places as possible, even if the community ultimately decides not to accept such suggestions.  So if there is some group who may have useful ideas who are reaching out to the moderators, then I think that the moderators should be as receptive as possible without committing the community to any course of action.  Because I think that the situation is mysterious, I think we should avoid making assumptions about what kind of insights and suggestions we might receive.&lt;/p&gt;&#xA;" OwnerUserId="10366" LastEditorUserId="10366" LastEditDate="2021-01-06T18:04:35.703" LastActivityDate="2021-01-06T18:04:35.703" CommentCount="30" ContentLicense="CC BY-SA 4.0" />

There aren't off-site groups knocking on the moderators' door, much less seeking to help set policy for MO. That sounds like the bubblings of some conspiracy theory.&lt;/p&gt;&#xA;&lt;p&gt;I will attempt to clarify what is really going on, before more such &amp;quot;telephone&amp;quot; rumors emerge.&lt;/p&gt;&#xA;&lt;p&gt;There is widespread perception within the mathematics community at large that MO is important but can be a highly unwelcoming place. You may disagree with that, but the perception is undeniably there. And of course the members of the MathOverflow board are highly aware of that perception, and that it may be a serious problem for us in the long run. What should or can we do about it, if anything? We really don't know. Should we simply close our eyes to it, pretend there's nothing there? Doesn't seem like a good idea.&lt;/p&gt;&#xA;&lt;p&gt;After some internal discussion within the board (which consists of the current moderators, Anton Geraschenko, and Ravi Vakil who has been part of the MO venture since the very beginning), we've put together a list of people who we thought might be able to help clarify the nature of the perceived problem. The list comprises both MO community members of long standing and respect (both here and IRL), as well as others outside who are prominent in the mathematical community, and who see MO from the outside. It's we, the board, who are seeking them out -- not the other way around. Only a few so far have gotten back to us. And they are not 'groups'. They are disparate individuals that some of us know, who have their own ideas and opinions, and who will probably disagree with each other in various respects. They didn't even know this was coming. But they are on the list because at least some of us know them, and trust to be people who can help drive a fruitful conversation.&lt;/p&gt;&#xA;&lt;p&gt;And for now we are simply proposing to have a discussion (none has occurred yet), and yes, if we reach some shared idea about what the problem is or how extensive it is, we would also encourage &lt;em&gt;suggestions&lt;/em&gt; for what (if anything) might reasonably be done about it. This is not even remotely close to the point of &amp;quot;setting policy&amp;quot;! For example, there would be no 'vote' taken within that group. We would not propose or presume any policy-making without an open discussion, here, before the community.&lt;/p&gt;&#xA;&lt;p&gt;The list of people we compiled is not a matter for the MO Community to vote on, nor is it even a matter up for discussion. It is not after all a deliberative body that will vote to make decisions for the MO community and for which minutes will be taken and made public. Additionally, I hope it makes sense that sometimes, in order to have a frank and productive conversation where people can freely speak their minds, it's not always a great idea to have everything be public. In the present case, we feel discussion will flow more freely if the participants know that their speech will not be dissected in a public arena so that every word must be carefully weighed and measured.&lt;/p&gt;&#xA;" OwnerUserId="2926" LastActivityDate="2021-01-07T16:46:56.213" CommentCount="16" ContentLicense="CC BY-SA 4.0" />

But the board is aware of the initiative, and I believe the members of the board are individually supportive of it (although there is no vote).  I understand that there is not universal agreement that MO is perceived as unwelcoming, especially to certain groups of people, and there is also not universal agreement that for the good of mathematics, MO should be more welcoming, and if so, what things can be influenced.    I wanted to ask some people to have an informal discussion about it in one place (rather than serial small discussions over many years), and I picked them quickly and without much thought (because I wanted to get it done, and I have limited bandwidth, to be honest).   I picked people who I think will be able to have a productive conversation together.  I'm intending to have this discussion over the course of a month.     This entire &amp;quot;group&amp;quot; is not official, and there is no way for it to set policy.

So I've asked people to keep the conversation itself privileged, and I also want them not to share the names of the other participants (although they can of course say they were part of the discussion, and talk about it in general terms).   For the discussion to work, there needs to be a high level of mutual trust.   I knew in advance (and the board did too) that this could be taken as some secret cabal of highly-connected insiders.  All I can I say is that this isn't the intent, and so if it is a secret cabal, I hope it is taken as my own action, asking people I know if we can chat about what I see as an important challenge for MO.

The current best hypothesis for why MO is either attractive or repellent in general is that it has to do with the reputation system.  As I was offering reasons for why things are structured as they are, it occurred to me that there are different goals that could be separated in the point system.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Goal 1: Determining good questions and answers.&lt;/strong&gt; Here, we vote on the questions and answers, and accept at most one answer. This is a crowd-sourced quality metric. Though one may argue about the details, it seems like basically a great idea.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Goal 2: Managing user privileges.&lt;/strong&gt; When you achieve certain reputation, you get more powers on the site. This allows the editorial work to be distributed among many experts who earn their expert status through their dedication of time and the quality of their mathematical content.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Goal 3: Quantifying users’ credibility.&lt;/strong&gt; This one speaks for itself.&lt;/p&gt;&#xA;&lt;p&gt;In my opinion, the above goals are listed in decreasing order of importance; Goal 1&amp;gt;Goal 2&amp;gt;Goal 3.  What occurs to me is:&lt;/p&gt;&#xA;&lt;p&gt;(a) Goals 2 and 3 do not have to be so tightly linked to Goal 1.  Goal 1 is an important local imperative, but good questions and answers can be generated by people who are do not have high rep or even participate much, and they frequently are.&lt;/p&gt;&#xA;&lt;p&gt;(b) Goal 2 is quantified at a second level with a more coarse system of statuses.  These could be awarded without the publicly viewable reputation points.&lt;/p&gt;&#xA;&lt;p&gt;(c) It is debatable whether Goal 3 is worthy or not.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Proposal 1:&lt;/strong&gt; Make reputation points a hidden feature that only administrators can see.

Yes, there would be good arguments about how it's silly to ban an entire field of mathematics due to a few bad actors.

A big mess would ensue, and the whole episode would risk driving people away from the site.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Scenario 2:&lt;/strong&gt; private debate.  Even if the proposal had one or two passionate advocates, the argument that banning a major field of mathematical research will help attract more MO users is untenable and would be killed quietly, assuming a suitably informed and diverse group of participants are invited to the discussion.&lt;/p&gt;&#xA;&lt;p&gt;Obviously scenario 2 is better.

Having only 6-7 names appearing in every closed question can be intimidating.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Encourage professional behavior in order not to turn away those that are familiar with the scope of MO.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Whether Mathoverflow is perceived as a welcoming community depends on the observer. If it is someone who is not very familiar with the website, then I think that being welcoming boils down to politeness. This is not just about redirecting questions that may not be research level, but also explaining various other procedures such as other members of the community editing one's posts, changing the tags, closing as duplicate etc.&lt;/p&gt;&#xA;&lt;p&gt;There are aspects of the website where the community's consensus is constantly evolving. When it comes to deciding what constitutes a &amp;quot;research level&amp;quot; topic, some users have a higher bar than others. As a corollary, the experience of a new contributor will be shaped differently depending on whom they come into contact with. For example, I have noticed that user abx has been vocal about casting votes to close on algebraic geometry questions that others might find ok or borderline, you may even have experienced this in a recent question of yours. I don't think that there is anything wrong with this (in fact I believe that many topics on MO could benefit from &amp;quot;raising the bar&amp;quot; a little bit) but perhaps it would be helpful if a new user could tell the difference between the opinion of a handful of users and the community as a whole.&lt;/p&gt;&#xA;&lt;p&gt;One way of achieving this is to discourage users from identifying themselves with all of MO. In the context of borderline questions, using phrases like &amp;quot;I think that your question is covered in a standard textbook like X and might have a better chance at attracting more elaborate answers at website Y&amp;quot; is probably better than an absolute &amp;quot;your question is not acceptable/welcome/appropriate on MO&amp;quot;. They essentially achieve the same goal, but the perception can be different. I guess the desired perception should be more along the lines of &amp;quot;community moderated&amp;quot; and less &amp;quot;policed by a small set of users&amp;quot;. The first scenario is one where every member can feel like they have a voice whereas the second is one where some members are left to feel sort of helpless.&lt;/p&gt;&#xA;&lt;p&gt;I think that the case of borderline questions is truly the place where you can clearly see how welcoming we choose to be as a community. Perhaps if we were able to treat them with more dialogue we might start seeing a change in perception. &lt;a href=&quot;https://mathoverflow.net/questions/59192/is-oeis-a001935-number-of-partitions-with-no-even-part-repeated-efficiently-co&quot;&gt;Here&lt;/a&gt; is what I think is a great example, where instead of getting closed, a question received constructive criticism as well as an edit that improved it.&lt;/p&gt;&#xA;&lt;p&gt;Now, for the case of someone who is familiar with the scope of MO, there are other things that matter more. The impression I get form personal conversations is that some of the factors which may paint an unwelcoming picture of MO include: 1) Non-mathematical debates that turn offensive or rude. 2) The lack of a unanimous agreement against hate speech/symbols (without bias on which country or culture they come from). 3) Users regularly posting controversial statements and then deleting them for the sake of creating confusion etc. Running into such threads on MO or meta can give the impression that this is not a professional environment. This can turn potential users away because they do not feel like the level of decorum is high enough to protect them from personal attacks, prejudice, bullying etc.&lt;/p&gt;&#xA;" OwnerUserId="2384" LastActivityDate="2021-01-12T01:24:54.300" CommentCount="8" ContentLicense="CC BY-SA 4.0" />

I have a Ph.D. in mathematics, although my regular job is as a professor of physics, and most—but not all—of my research is in theoretical physics.  Several years ago, I made a couple of posts on MathOverflow, and I definitely did not feel like I got a warm reception.  The responses I got could best be described as &amp;quot;chilly and cliquish.&amp;quot;  I felt like the way I framed my posts (based on my way of thinking as an applied mathematician) was not especially appreciated or even subtly sneered at.  Besides that, there just seemed to be essentially no interest in the kinds of approach I was interesting in taking.&lt;/p&gt;&#xA;&lt;p&gt;I considered and ultimately decided to suspend my account, and although I continue to read this stack, I did not post here again for many years.  I only very recently reactivated my MathOverflow account, after I was encouraged to do so by some other colleagues.  The response to the couple of questions I have asked since then has not been rude, but it has still been somewhat disheartening.  I have endeavored to formulate my questions in a very pure mathematics language, although there have been more applied motivations behind them.  The one substantive response I received was shallow and rather missed the point of the question, by trying to abstract it even beyond the level of artificial mathematical abstraction that I had already inserted into my query, in the hopes of attracting some interest from the very pure crowd who appear to predominate on this site.

There are several reasons for that: unlike a close vote, it is visible for all and therefore tends to have the effect of a &amp;quot;slap in the face&amp;quot;. When new users respond aggresively it is typically after their first down vote. Moreover, while a close vote may eventually lead to closing of the question, this then comes with suggestions to improve the question, so it has a more constructive feel. Down votes also tend to arrive very soon after the question is posted, giving the impression that users did not spend any time thinking about the question.&lt;/p&gt;&#xA;&lt;p&gt;I ask myself if down votes serve a purpose, and I am not so sure they do. Yes, they advertize on the front page that a question is not worth looking into, but seeing a question with 0 votes that has been around for some time conveys the same information. If a question is spam, then flagging it as such is quite effective at triggering a deletion, down votes do not seem needed for that purpose. Down votes do serve a ranking purpose for community wiki, big list, types of questions, but those are few and I guess that counting up votes would work just as well.&lt;/p&gt;&#xA;&lt;p&gt;I don't think we can change the way Stack Exchange works, I presume the option to down vote is here to stay, but we could decide as a community that we will not down vote off-topic questions, just close them.

  <row Id="4837" PostTypeId="2" ParentId="4835" CreationDate="2021-01-19T11:42:55.700" Score="9" Body="&lt;p&gt;Here are some additional &lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;SEDE&lt;/a&gt; queries. (As my knowledge of SQL is rather limited, take all of this with a grain of salt.)&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1359811/percentage-of-upvotes&quot; rel=&quot;nofollow noreferrer&quot;&gt;Percentage of Upvotes&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1359816/percentage-of-upvotes-multisite&quot; rel=&quot;nofollow noreferrer&quot;&gt;Percentage of Upvotes (multisite)&lt;/a&gt;. MathOverflow currently gives 91.94%.&lt;/li&gt;&#xA;&lt;li&gt;We can obtain average number of up/down-votes on &lt;em&gt;post which weren't deleted&lt;/em&gt; if we look into table &lt;code&gt;Posts&lt;/code&gt; rather than &lt;code&gt;PostsWithDeleted&lt;/code&gt;. (But we must restrict the votes to those questions too, which adds a bit more complexity to the query and makes it run slower.) Here is a query which does that: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1359903/upvotes-downvotes-per-posts-only-the-post-which-are-not-deleted&quot; rel=&quot;nofollow noreferrer&quot;&gt;Upvotes/downvotes per posts - only the post which are not deleted&lt;/a&gt;. (I will add a link to &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1359906/upvotes-downvotes-per-post-testing&quot; rel=&quot;nofollow noreferrer&quot;&gt;the same query where Posts is replaced with PostDeleted&lt;/a&gt; - if the query works correctly, this should give the same numbers as Glorfindel's query for deleted posts.) If we only take posts which weren't deleted, this gives 0.16 downvote per post - compared to 0.46 if we include the deleted posts.&lt;/li&gt;&#xA;&lt;li&gt;We could also look at average number of downvotes cast by a user. Of course, it probably does not make sense to take all users - since many users have an account here but they have never done anything on the sites.&#xA;Here is a SEDE query which &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1359889/number-of-upvotes-downvotes-per-user?min=125&quot; rel=&quot;nofollow noreferrer&quot;&gt;counts users with reputation at least 125&lt;/a&gt; - it returns 10.75 as the average for MO. (I chose 125, since this is the reputation &lt;a href=&quot;https://mathoverflow.net/help/privileges/vote-down&quot;&gt;needed for downvoting&lt;/a&gt;.&#xA;You can change the parameter in the query to any different threshold. For example, if you want to see how generous are the users with upvotes, perhaps it is more sensible to &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1359889/number-of-upvotes-downvotes-per-user?min=15&quot; rel=&quot;nofollow noreferrer&quot;&gt;set it to 15&lt;/a&gt;, since users can &lt;a href=&quot;https://mathoverflow.net/help/privileges/vote-up&quot;&gt;upvote from 15 reputation points&lt;/a&gt;. Here MO is among the most upvoting sites, with average 33.64 upvotes per user.)&lt;/li&gt;&#xA;&lt;li&gt;Mostly as curiosity I will include what are the results if we take anonymous feedback&lt;sup&gt;1&lt;/sup&gt; instead of votes. Glorfindel's &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1359848/voting-statistics-from-anonymous-feedback&quot; rel=&quot;nofollow noreferrer&quot;&gt;query with Upvotes/Downvotes per post&lt;/a&gt; gives 0.28 upvotes and 0.12 downvotes as average after this modification. If we look at the &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1359849/percentage-of-upvotes-in-anonymous-feedback&quot; rel=&quot;nofollow noreferrer&quot;&gt;percentage of upvotes&lt;/a&gt; we get 69.94% from anonymous feedback.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;მამუკა ჯიბლაძე &lt;a href=&quot;https://meta.mathoverflow.net/questions/4835/do-we-use-the-downvote-button-more-than-other-sites/4837#comment24762_4837&quot;&gt;suggested in a comment&lt;/a&gt; to look specifically at new users. The following queries only look at the posts which weren't deleted, which should exclude stuff such as obvious homework. (You can use similar queries with PostsWithDeleted table instead of Posts, if you want to included the deleted posts, too.)&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Here is a graph showing &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1367248/count-of-questions-by-newish-users#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;number of question by users with accounts at most 100 days old&lt;/a&gt; (at the time of the post).

(You can change the parameter to see results for a different number of days.)&lt;/li&gt;&#xA;&lt;li&gt;Average number of downvotes per question for such users &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1367243/upvotes-downvotes-on-questions-by-newish-users&quot; rel=&quot;nofollow noreferrer&quot;&gt;only on MO&lt;/a&gt; and a &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1367245/upvotes-downvotes-on-posts-by-newish-users-multisite&quot; rel=&quot;nofollow noreferrer&quot;&gt;multisite query&lt;/a&gt;. It gives the average 0.28 for downvotes and 5.9 for upvotes.&lt;/li&gt;&#xA;&lt;li&gt;Similar query for answers &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1367258/upvotes-downvotes-on-answers-by-newish-users&quot; rel=&quot;nofollow noreferrer&quot;&gt;on MO&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1367268/upvotes-downvotes-on-answers-by-newish-users-multisite&quot; rel=&quot;nofollow noreferrer&quot;&gt;the multisite query&lt;/a&gt; (which runs a much longer for answers). It returns 7.55 upvote and 0.19 downvote in average.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;These are &amp;quot;votes&amp;quot; from users who actually cannot cast votes - they are recorded as feedback but do not influence score/reputation.

Every bit of time and effort y'all contribute to the site gives you access to more privileges you can use to help in this effort, all of which produce a cumulative effect that makes a big difference.&lt;/p&gt;&#xA;&lt;p&gt;So as we welcome 2021, and in keeping with tradition, let us look back at what we accomplished as a community... by looking at some &lt;a href=&quot;https://i.stack.imgur.com/pU1Al.jpg&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;em&gt;exciting&lt;/em&gt; stats&lt;/a&gt;.

Numerical linear algebra is the basis of scientific&#xA;computing, and its importance for the sciences and engineering can hardly&#xA;be overestimated. The ubiquity of linear algebra masks the fairly recent&#xA;growth of nonlinear models across the mathematical sciences. There has&#xA;been a proliferation of methods based on systems of multivariate polynomial&#xA;equations and inequalities. This is fueled by recent theoretical advances, efficient software, and an increased awareness of these tools. At the heart&#xA;of this lies algebraic geometry, but there are links to many other branches,&#xA;such as combinatorics, algebraic topology, commutative algebra, convex and&#xA;discrete geometry, tensors and multilinear algebra, number theory, representation theory, and symbolic and numerical computation. Application areas&#xA;include optimization, statistics, complexity theory, among many others.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Nonlinear algebra is not simply a rebranding of algebraic geometry. It&#xA;is a recognition that a focus on computation and applications, and the theoretical needs that this requires, results in a body of inquiry that is complementary to the existing curriculum. The term nonlinear algebra is intended&#xA;to capture these trends, and to be more friendly to applied scientists. A special research semester with that title, held in the fall of 2018 at the Institute&#xA;for Computational and Experimental Research in Mathematics (ICERM) in&#xA;Providence, Rhode Island, explored the theoretical and computational challenges that have arisen, and it charted the course for the future.

Just an engineer who is interested and oftentimes fascinated with math. My first experience on this site was when I asked &lt;a href=&quot;https://mathoverflow.net/questions/241637/needing-proof-of-convergence-for-a-sequence&quot;&gt;this question&lt;/a&gt; some years ago. It actually was a cross-post from MSE, which received a really poor answer there. So I thought it might be advanced enough to be posted here. I wasn't at all familiar with the atmosphere in here and to be honest, I had no idea how to ask a good question. Yes, there is a help page for every site, but like the manuals for the tools we buy, who is gonna bother to read them?&lt;/p&gt;&#xA;&lt;p&gt;I admit that my question wasn't in good shape and had a poor wording, mostly because of my lack of experience in English writing and unfamiliarity with the merits of writing clear mathematics. But I was lucky enough to have a goodwilled commentator who patiently guided me through editing my question and didn't take offense in my initial arrogance. (I don't remember his name as the comments are now deleted).&lt;/p&gt;&#xA;&lt;p&gt;Now the point is, my personal experience on this site was the fact that this community is very welcoming, maybe because I was lucky. And maybe someone else would have flagged my question and subsequent comments as inappropriate (and they would be right to do so) and the result would have been different. But showing a little patience and goodwill not only caused that question to be well-received and perfectly answered, but also strengthened my interest and fascination with advanced math topics. Since then, I am a regular visitor to this site and have learnt a lot from its wonderful contributors. Although I don't understand most of its Q&amp;amp;As but I sometimes read them anyway like a monkey staring at a book.

I don't know if there are any active efforts of trying to understand the phenomenon you describe, I don't know who would have to run such efforts in any case. But the thing is that what I've seen so far in these meta discussions is that it's mostly hardcore users discussing the merits of the community, this is bound to happend of course, but it's a bit hard to deduce why people don't stick around when you only poll the ones that did.&lt;/p&gt;&#xA;&lt;p&gt;Now my own personal take as an 'advanced' grad student, whatever that means. I reiterate this is why I personally barely ever participate even if Ive visited the site almost daily for the past few years. It takes a lot for me to produce any input.&lt;/p&gt;&#xA;&lt;p&gt;First of all, the format itself almost forces one to a particular style of conversation. The format, the moderation and the vibe itself of the site makes it hard to deviate into having an organic conversation between many people. It hard to go even so slightly off-topic. If I, as a student read an answer that I find relevant to my interests but that I don't understand fully although I know I would with a little bit of help to fill some gaps, it is a bit hard to hop in the conversation and interrupt the almost linear format of the comments to ask for clarification. I can't hijack a comment thread to make it about my own lack of understanding. Which leads me to my second point.&lt;/p&gt;&#xA;&lt;p&gt;Asking a question in an open forum is not a conversation with coffee and snacks after a seminar, nor is it raising your hand after a talk. It's getting up on stage and facing the crowd. It's daunting and I believe it is natural that for most people just trying to break inside the mathematical community to be reluctant to post their questions in a forum like this. Some people can shake off saying something silly here years ago, but a lot would see it as a risk with negatives outweighing the positives. Of course one could post anonymously, but I believe this is discouraged here. I believe this is a factor anyway. I would've loved to post this from a fully anonymous account, for example.&lt;/p&gt;&#xA;&lt;p&gt;On the topic of the questions themselves. It is a struggle itself to come up with good question, not to mention having the skills to make a dent on them. If I'm barely getting by with the work I do, it's a bit of a risk to give away a good question or partial work away for somebody to solve a couple-months-project in a few -sometimes- non even that illuminating paragraphs. I've seen people asking bits and pieces of the questions I plan for my thesis and it's pretty stressing. This is perhaps a very unscientific attitude to have, but at the end of the day it's a fierce competition, sadly. Often people try to conceal their questions by trying to abstract away the context, but this often leads to a poor question or poor answers that understandably miss the point.&lt;/p&gt;&#xA;&lt;p&gt;Last but not least, and a bit of a summary of the previous points, is that the site has a reputation already. People here sometimes try to reason that the attitudes that resulted in this reputation have been mostly eradicated since the early days of the site, but when I google a question and I arrive to a 10 year old post and see somebody being a bit condescending or a bit rash with their answers then my perception is there. Nobody ever explicitly told me about the reputation of the site but it is true that most of the grad students Ive met through the years and institutions don't have a good look on the site, thinking of it as too intimidating in the better cases to outright unhelpful and aggressive in the worst. While it is maybe true that the community is overall kinder in more recent times there's still the odd comment that is not very helpful (not necessarily rude, or mean) with the reputation.&lt;/p&gt;&#xA;&lt;p&gt;I know there are plenty of (ex)grad students who (were)are very active and thrived just fine, so it's certainly possible to be a part of the community at this stage of one's training. But for me and maybe others it just feels like it's not worth it most of the time. Maybe the community should decide if it's willing to make changes to attract more 'advanced' graduate students, or if its goals are in conflict with what people staying out would want to see.&lt;/p&gt;&#xA;" OwnerUserId="44499" LastEditorUserId="8250" LastEditDate="2021-02-14T17:07:12.050" LastActivityDate="2021-02-14T17:07:12.050" CommentCount="17" ContentLicense="CC BY-SA 4.0" />

Personally, I think it would be productive to try to reformulate the adjective &amp;quot;research-level&amp;quot; in a better way. After all, the idea that mathematics is a &amp;quot;linearly-ordered&amp;quot; subject, progressing from grade-school concepts to high school concepts to undergraduate concepts to graduate concepts to research concepts, is a widespread misconception. I don't think I'm alone in &lt;em&gt;wincing&lt;/em&gt; every time I tell someone I'm a mathematician and get the response &amp;quot;Oh, I never &lt;em&gt;got past&lt;/em&gt; calculus&amp;quot;. So this whole business is problematic, but I think that has been at least partially addressed in other responses.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The issue of being perceived as &amp;quot;unwelcoming&amp;quot; is not unique to Math Overflow -- it's a widespread phenomenon on the Stack Exchange network, particularly on the flagship site Stack Overflow, as documented in &lt;a href=&quot;https://stackoverflow.blog/2018/04/26/stack-overflow-isnt-very-welcoming-its-time-for-that-to-change&quot;&gt;the company blog&lt;/a&gt;, &lt;a href=&quot;https://meta.stackoverflow.com/questions/262791/the-rudeness-on-stack-overflow-is-too-damn-high&quot;&gt;meta&lt;/a&gt;, &lt;a href=&quot;https://meta.stackoverflow.com/questions/366692/how-do-you-know-stack-overflow-feels-unwelcoming?noredirect=1&amp;amp;lq=1&quot;&gt;meta&lt;/a&gt;, &lt;a href=&quot;https://medium.com/hackernoon/the-decline-of-stack-overflow-7cb69faa575d&quot; rel=&quot;nofollow noreferrer&quot;&gt;news articles&lt;/a&gt;, and &lt;a href=&quot;https://www.reddit.com/r/ProgrammerHumor/comments/k01blo/asking_on_reddit_vs_asking_on_stack_overflow/&quot; rel=&quot;nofollow noreferrer&quot;&gt;memes&lt;/a&gt;. And among &amp;quot;curated knowledge&amp;quot; sites, it's not unique to the Stack Exchange network -- for example &lt;a href=&quot;https://www.vice.com/en/article/4xangm/wikipedia-editor-says-sites-toxic-community-has-him-contemplating-suicide&quot; rel=&quot;nofollow noreferrer&quot;&gt;wikipedia&lt;/a&gt; struggles with analogous issues. I can't say I've carefully considered the issue from this broader perspective, but I do think that any attempt to grapple with these issues would do well to take a look at other places where similar problems have been encountered and (hopefully) solutions have been formulated.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;Of course, there are other broad contexts in which to situate the issue, such as the &amp;quot;welcomingness&amp;quot; of mathematics as a discipline, academia as a whole, and so forth. But I think the peculiarities of the dynamics of Stack Exchange and similar sites are particularly relevant, and underrepresented in the discussion here.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;EDIT:&lt;/strong&gt; To expand on (2), I'd like to meditate on a recent experience on a different SE site. A few months ago I asked &lt;a href=&quot;https://physics.stackexchange.com/questions/574831/applications-of-position-space-formula-for-a-feynman-propagator?&quot;&gt;this question&lt;/a&gt; on Physics SE, a site I have occasionally visited, but with which I'm not all that familiar. The question attracted a good answer, but was also attracting votes to close for being &amp;quot;opnion-based&amp;quot;. I made some edits to remove any language I thought might be interpretable as &amp;quot;opinion-based&amp;quot;, but to no avail -- the question was still closed as &amp;quot;opinion-based&amp;quot;. With no further feedback, I thought I'd done all I could and gave up, figuring that Physics SE had their own inscrutable criteria for acceptable questions on their site, and that it was not worth trying to get to the bottom of things at the time.&lt;/p&gt;&#xA;&lt;p&gt;A few days ago, I decided to give it another crack. My only lead was the close reason -- it was &amp;quot;opinion-based&amp;quot;. So I scoured the question for anything which might whiff of an opinion, and excised it. I speculated that the given close reason was not the true close reason -- probably the last few votes to close, made after my edits, had simply chosen to give the same reason as the earlier votes for simplicity, even though the reasons had changed. I recorded these speculations in the comments, but I didn't attempt to rectify any of these hypothetical issues.&lt;/p&gt;&#xA;&lt;p&gt;I submitted the question to be reopened. A helpful moderator came along and improved my tags. While still closed, the question attracted another good answer in the comments. Eventually it was reopened, before being immediately closed for a new reason -- it lacked focus. I was confused again, but this time the same moderator left a helpful comment explaining that my question needed to have a unique answer to be acceptable.&lt;/p&gt;&#xA;&lt;p&gt;Aha! It was indeed a community difference. I'm pretty certain that my question as currently phrased would be the sort of focused, limited list question we'd embrace at MO (maybe in community wiki format, but honestly we probably wouldn't even bother with that), but over there any list question was a non-starter. This wasn't in their FAQs, but there was some old discussion on meta on the topic. The helpful moderator helpfully listened when I raised these points in the comments, and eventually helpfully reversed the second closure despite personally feeling that the &amp;quot;list&amp;quot; objection was strong. We'll see where it goes.&lt;/p&gt;&#xA;&lt;p&gt;I'm drawing a few lessons from this:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;To a new user, our criteria for deciding whether a question is acceptable are doubtless completely inscrutable. Even an experienced user on another SE site who has some reasonable idea of what &amp;quot;research mathematics&amp;quot; is will likely find it extremely frustrating trying to meet these opaque standards. For a user who doesn't have experience on another SE site, it will be unclear that there even are standards -- it will appear that their questions are being categorically rejected for no reason at all.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;At the same time to our users, many of these criteria seem self-evident. We may have internal debate over what exactly &amp;quot;research mathematics&amp;quot; is, but we probably don't even realize that there are subtle conventions of phrasing and so forth which have never been made explicit that we pick up on and use to determine acceptability of questions.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If we don't even consciously know some of the reasons we find questions unacceptable, it's extremely difficult for these reasons to be communicated to new users.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Things like official close reasons are very blunt tools for communicating what's wrong with a question. Expanding in a comment is better, but there's still going to be a communication gap.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;" OwnerUserId="2362" LastEditorUserId="2362" LastEditDate="2021-02-03T14:55:24.313" LastActivityDate="2021-02-03T14:55:24.313" CommentCount="2" ContentLicense="CC BY-SA 4.0" />

I &lt;a href=&quot;https://physics.meta.stackexchange.com/questions/13349/the-proposed-changes-to-the-text-editor-would-break-this-site&quot;&gt;raised this yesterday on the Physics meta&lt;/a&gt;, but it's also relevant for you guys and I haven't seen you guys there, so I thought I'd nudge you in that direction.&lt;/p&gt;&#xA;&lt;p&gt;Specifically, the design prototypes, as they currently stand, get rid of the live preview of the post rendering. As far as I'm concerned, this completely breaks typing mathematics as we know it within the SE sphere. From what I can see, the design team is open to creating solutions that will work for the mathy sites, and they are approaching the design with an open attitude, but this will only work if the community pitches in, in constructive ways, to help them find ways that make our sites better instead of breaking them.&lt;/p&gt;&#xA;&lt;p&gt;So, with that in mind, I would like to ask you to join your voices to the debate. &lt;a href=&quot;https://meta.stackexchange.com/a/360142/184688&quot;&gt;My answer on the MSE thread&lt;/a&gt; details my concerns, and they seem to be getting a reasonable reception from the design team.

In short:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;As currently envisaged, the &lt;em&gt;only&lt;/em&gt; way to preview MathJax before publishing a post will be by toggling out of markdown mode and into the new rich text editor.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;This is unacceptable, because it means that instead of a real MathJax preview, we will be using whatever pale imitation of a MathJax preview the developers at Stack Exchange manage to shoehorn into their rich text editor in their spare time. For instance, it's likely there will be no way to preview the rendering of user-defined macros.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;&lt;strong&gt;Solution:&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;The only solution I see is to convince Stack Exchange to include some form of dedicated preview for markdown mode which is not reliant on rich text mode, and which fully supports MathJax. Given that this is a less demanding requirement than what currently exists, I pray that our overlords will find it feasible to do something like this.&lt;/p&gt;&#xA;&lt;p&gt;To my mind, the most important thing is not whether the preview is side-by-side, stacked vertically as at present, exists as a separate view, even a third &amp;quot;mode&amp;quot; in addition to markdown and rich text, whatever. The most important thing is that it exists, is independent from the rich text editor and fully supports MathJax. But we should start thinking about details like this -- if all goes well, Stack Exchange ought to be soliciting our input on such matters as we move forward.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;I've also left an &lt;a href=&quot;https://meta.stackexchange.com/questions/360033/opt-in-alpha-test-for-a-new-stacks-editor/360304#360304&quot;&gt;answer&lt;/a&gt; at the main meta site discussing this in more detail. It's a chore to look through all the answers over there, but it appears that others have also raised concerns about MathJax integration. Emilio also points out there there are several sites which also rely on other formatting plugins, such as &lt;a href=&quot;https://chess.meta.stackexchange.com/questions/179&quot;&gt;chess&lt;/a&gt;, &lt;a href=&quot;https://boardgames.meta.stackexchange.com/questions/425&quot;&gt;go&lt;/a&gt;, &lt;a href=&quot;https://japanese.meta.stackexchange.com/questions/199&quot;&gt;furigana&lt;/a&gt; and &lt;a href=&quot;https://music.meta.stackexchange.com/questions/2581&quot;&gt;music notation&lt;/a&gt;, which would suffer much like MathJax users in the currently-envisaged system. We need to band together and clearly articulate our needs. As Emilio points out, MO's unique arrangement with Stack Exchange gives us some extra leverage compared to many other sites. For this reason, and because we would among the sites most severely affected by theses changes, it is incumbent upon us to take a particularly active role in this effort.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Original Answer:&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;A bit long for a comment:&lt;/p&gt;&#xA;&lt;p&gt;Thanks, Emilio, for bringing this up here! I already flew off the handle in the comments to Emilio's answer at the main meta question under the impression (which I now believe to be mistaken) that the proposed changes would force one to use rich text with no option to revert to markdown. I now understand what they're proposing &lt;em&gt;would&lt;/em&gt; include the option to revert to markdown, but that there would be no live preview in the markdown mode.&lt;/p&gt;&#xA;&lt;p&gt;This is not as catastrophic as I first thought, but it would mean you're tying a hand behind your back. In order to catch minor errors you'd have to either publish and see the render and then make a series of public edits, or else toggle to rich text and cross your fingers that the rich text representation is adequate to catch stuff.&lt;/p&gt;&#xA;&lt;p&gt;As pointed out over there, the preview is actually in some sense an upgrade over many latex editors because of the automatic and constant refresh. I suppose I don't &lt;em&gt;need&lt;/em&gt; the refresh to be so frequent, and I don't &lt;em&gt;need&lt;/em&gt; it to be automatic, but it sure is nice. If it's not going to be there, I would prefer to have a &amp;quot;compile&amp;quot; button rather than &amp;quot;toggling to rich text mode&amp;quot;. The latter feels more clunky -- every time I toggle, the refresh is going to be loading all sorts of rich text functionality which is irrelevant to me, in addition to rendering the mathjax that I actually need to see.&lt;/p&gt;&#xA;" OwnerUserId="2362" LastEditorUserId="2362" LastEditDate="2021-01-31T18:05:49.880" LastActivityDate="2021-01-31T18:05:49.880" CommentCount="8" ContentLicense="CC BY-SA 4.0" />

At the very least, the &lt;code&gt;align&lt;/code&gt; environment needs to be replaced by &lt;code&gt;aligned&lt;/code&gt;, which entails editing 7.5k posts on physics, 1.8k on MO and 50k+ on math.se. For fancier behaviour we would need to have a very detailed look.&lt;/li&gt;&#xA;&lt;li&gt;Independently of the maturity of KaTeX, it's unclear to me how mature the prosemirror-math software is. Their To Do list includes &amp;quot;Test in FireFox, Safari, Edge&amp;quot; and their last commit was four months ago, and that's not a good sign.&lt;/li&gt;&#xA;&lt;li&gt;It's unclear to me how fast the preview would be on prosemirror-math, and how it would be affected by a slow connection speed. If there is a danger that the preview slows down on lower bandwidths, then that is exclusionary and unacceptable -- but it isn't detected unless specifically tested for, so it needs to be explicitly checked.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;In any case, independently of those technical hiccups, we as users should answer the question: is the style of editing offered by this solution something we can work with? I for one find it intriguing, but I don't want to say 'yes' without trying it out (and it's unclear whether there are any solutions that can do that at the moment).&lt;/p&gt;&#xA;" OwnerUserId="20729" LastActivityDate="2021-02-01T12:06:13.390" CommentCount="10" ContentLicense="CC BY-SA 4.0" />

But it &lt;a href=&quot;https://meta.mathoverflow.net/a/4862/2362&quot;&gt;now seems&lt;/a&gt; that among the options Stack Exchange has suggested so far, the most reasonable one would entail exactly that, as it would involve switching to some different Latex-like framework.&lt;/p&gt;&#xA;&lt;p&gt;If we go down that road, then we're going to have to get even more involved with things: we will need to think about which Latex / MathJax features we need to have supported on the site. Because if you leave it to the developers to decide which Latex features are worth supporting, then you end up with something like the Microsoft Equation Editor, a sort of caricature of what it means to support mathematical typesetting.&lt;/p&gt;&#xA;&lt;p&gt;Though this would be a large task, it also &lt;strong&gt;presents an opportunity&lt;/strong&gt;. If we were to switch away from MathJax, whatever new solution replaces it might be an &lt;em&gt;improvement&lt;/em&gt; in certain respects.&lt;/p&gt;&#xA;&lt;p&gt;So perhaps I'm jumping the gun, but I think it may be worth getting started on this task. We're still in the early stages, so there's no way we will come to a definitive or comprehensive answer right now, but we may start to get some ideas. Up to now, I've never had to dialog with a non-mathematician about what I need in Latex, so I'm not really sure what their preconceptions are about what we need. Some things I might guess they don't anticipate include user-defined macros and commutative diagrams, but there are probably much more basic things they'll need to have explained. On the flip side, my impressions of what they will find difficult or easy to implement are just as ill-informed as their impressions of what we will need. So the question is:&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Which Latex features are important to have supported on this site? Which ones, if not strictly necessary, would be very nice to have supported?&lt;/p&gt;&#xA;&lt;p&gt;It's worth considering both features which are currently supported by MathJax, and ones which are not.&lt;/p&gt;&#xA;" OwnerUserId="2362" LastEditorUserId="2362" LastEditDate="2021-02-02T15:31:37.270" LastActivityDate="2021-03-17T21:31:42.623" Title="Which Latex / MathJax features do we need or want to have supported on the site?"

The fact that I like this site has heavily to do with the fact that I am a masochist; I only play video games on the hardest mode available (even if I end up breaking controllers and destroying whole systems), I purposefully don't prepare for lectures or talks to force myself to come up with them on the spot, and I post to MO knowing that I might get a dunce cap strapped to my head while someone tries to make me read hieroglyphs out loud to the world.&lt;/p&gt;&#xA;&lt;p&gt;I think this sort of 'trial by fire' is one of the best ways for a person to quickly up their game, and MO is a paragon for this sort of mental honing stone in mathematics. I can't count on both hands the number of times I've been embarrassed because I said something dumb to an expert on MO, but I also can't count on both hands and feet the number of times I've had my own knowledge dramatically improved by these experts responses to my dumb questions. I do get the occasional &amp;quot;f*** off and read a book&amp;quot; vibe from the communities I interact with here, but sometimes that is appropriate -- MO is meant to be a repository for research level questions, and if the answer to a question is non-specific (not a single lemma) and covered at large by a well-known text it is appropriate for the questioner to leave and do some reading before they come back to ask a more specific question.&lt;/p&gt;&#xA;&lt;p&gt;The only type of interaction I've had on here that is totally valueless is the dreaded 'anonymous downvote with no explanation', in particular if it is within the first 10-20 views on a question that isn't obviously stupid or too low-level. I had this happen a few times early on, and if I were the sort of person to take discouragement sitting down it may have dissuaded me from further participation; fortunately for me haters are motivators, so these anonymous and useless interactions only drove me to improve my questions further and make sure the community at large saw the value in them. I think that the dunce-capping and hieroglyph-reciting mentioned above, while unpleasant, serve an immediate and beneficial purpose for the site and to the users of the site -- the anonymous downvotes with no explanation do neither, and stand to cause harm to the sites reputation and the psychology of its newer users.

When you use two of them, the markdown processor happily converts them to &lt;code&gt;&amp;lt;em&amp;gt;&lt;/code&gt; and &lt;code&gt;&amp;lt;/em&amp;gt;&lt;/code&gt; and then MathJax has no chance.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Proposed solution 1:&lt;/strong&gt; Don't use markdown special characters in &lt;code&gt;\label{}&lt;/code&gt;. The label you use isn't visible anyway (only the tag is).&lt;/p&gt;&#xA;&lt;p&gt;Note also that when all the the MathJax on the page is processed together (which doesn't happen in preview), repeated labels will cause &amp;quot;Label multiply defined&amp;quot; errors in MathJax, because MathJax don't know anything about the semantics of questions and answers ... it's just one big web page to it. However, the same &lt;strong&gt;tag&lt;/strong&gt; being repeated is totally fine (albeit potentially confusing to the reader).&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Proposed solution 2:&lt;/strong&gt; Put your &lt;code&gt;\eqref{}&lt;/code&gt; in dollar signs so that the markdown processor ignores it.&lt;/p&gt;&#xA;&lt;h2&gt;Demonstrations&lt;/h2&gt;&#xA;&lt;p&gt;Problem: (Note I'm using &lt;code&gt;_&lt;/code&gt; instead of &lt;code&gt;*&lt;/code&gt; to avoid global collision with the label in your question)&lt;/p&gt;&#xA;&lt;pre&gt;&lt;code&gt;$$\begin{equation} A = B \tag{*}\label{_} \end{equation}$$&#xA;Look at equation \eqref{_}; isn't equation \eqref{_} awesome?&#xA;&lt;/code&gt;&lt;/pre&gt;&#xA;&lt;p&gt;produces the following output:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$\begin{equation} A = B \tag{*}\label{_} \end{equation}$$&lt;/span&gt; Look&#xA;at equation \eqref{&lt;em&gt;}; isn't equation \eqref{&lt;/em&gt;} awesome?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Solution 1:&lt;/p&gt;&#xA;&lt;pre&gt;&lt;code&gt;$$\begin{equation} A = B \tag{*}\label{ast} \end{equation}$$&#xA;Look at equation \eqref{ast}; isn't equation \eqref{ast} awesome?&#xA;&lt;/code&gt;&lt;/pre&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$\begin{equation} A = B \tag{*}\label{ast} \end{equation}$$&lt;/span&gt; Look&#xA;at equation \eqref{ast}; isn't equation \eqref{ast} awesome?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Solution 2: (Note I'm using &lt;code&gt;__&lt;/code&gt; instead of &lt;code&gt;_&lt;/code&gt; to avoid collision with the problem demonstration)&lt;/p&gt;&#xA;&lt;pre&gt;&lt;code&gt;$$\begin{equation} A = B \tag{*}\label{__} \end{equation}$$&#xA;Look at equation $\eqref{__}$; isn't equation $\eqref{__}$ awesome?&#xA;&lt;/code&gt;&lt;/pre&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$\begin{equation} A = B \tag{*}\label{__} \end{equation}$$&lt;/span&gt; Look&#xA;at equation &lt;span class=&quot;math-container&quot;&gt;$\eqref{__}$&lt;/span&gt;; isn't equation &lt;span class=&quot;math-container&quot;&gt;$\eqref{__}$&lt;/span&gt; awesome?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Global collision example:&lt;/p&gt;&#xA;&lt;pre&gt;&lt;code&gt;$$\begin{equation} A = B \tag{*}\label{*} \end{equation}$$&#xA;&lt;/code&gt;&lt;/pre&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$\begin{equation} A = B \tag{*}\label{*} \end{equation}$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;" OwnerUserId="1" LastEditorUserId="1" LastEditDate="2021-03-04T19:14:19.857" LastActivityDate="2021-03-04T19:14:19.857" CommentCount="7" ContentLicense="CC BY-SA 4.0" />

For instance, I suspect one reason they haven't implemented something like the suggestion Martin linked to is that they realize that would just be the first step in an arms race with the spammers which they simply don't want to get involved in.&lt;/p&gt;&#xA;&lt;p&gt;One reason is that if you delete a spammy account, the spammer can very easily immediately recreate their account, making the task a bit sysiphian. The Charcoal folks recommend that if one is going to put effort into deleting spammy accounts, it's usually best to wait a few days before deleting, in the hopes that the spammer will have turned their attention elsewhere by that time.&lt;/p&gt;&#xA;&lt;p&gt;The suggestion seems to be that it &lt;em&gt;is&lt;/em&gt; possible to fight this kind of spam on a per-site basis, and it's possible to partially automate the process, but that because there will always need to be a human in the loop to avoid deleting non-spammy accounts, going this route requires having one or more moderators who feels invested in deleting spam accounts. I don't feel strongly enough about this to ask our moderators to take on such a drudgery-filled duty.&lt;/p&gt;&#xA;&lt;p&gt;For the record, I suspect the specific motivation for this question was that the other day one of these spam accounts went a bit beyond the usual spam and had an &lt;em&gt;offensive&lt;/em&gt; username (certainly that's what got me interested in the question -- I even asked a duplicate question, deleting it once I realized you'd asked this one).

Regarding senses (1,2,3,4) from the OP:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;There may be a distinction to be made here, but it seems that such a distinction isn't really the sort of distinction which merits having a tag of its own.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;As per Rodrigo de Azevedo's suggestion, this sense is basically a synonym for the &lt;a href=&quot;https://mathoverflow.net/questions/tagged/applied-mathematics&quot;&gt;applied-mathematics&lt;/a&gt; tag.

While I don't have a full list of all of these things, much can be customized, so if y'all would like to do so, figure out whether the thing you'd like to customize can be changed (a mod can reach out to the CMs to ask) and have a discussion about it here so that people can weigh-in on the issue.&lt;/p&gt;&#xA;&lt;p&gt;Here's a good example of such a discussion - &lt;a href=&quot;https://meta.mathoverflow.net/questions/4806/customize-the-modal-window-for-the-first-time-askers&quot;&gt;Customize the modal window for the first-time askers&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;Once the discussion is at a place where you need staff to actually come and review the changes and get them changed, you can ask the moderators to add the &lt;a href=&quot;/questions/tagged/status-review&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;status-review&amp;#39;&quot; rel=&quot;tag&quot;&gt;status-review&lt;/a&gt; tag, which will be added to the CMs' backlog and we'll review it and get it triaged.&lt;/p&gt;&#xA;&lt;p&gt;It's worth stating here that, while we will respond to the request and give you an answer about whether we can do it or not - this process doesn't guarantee that we will do it, particularly in the case of feature requests for new tools or features on the site. We have some guidance about this process on the main Meta - &lt;a href=&quot;https://meta.stackexchange.com/questions/348642/what-posts-should-be-escalated-to-staff-using-status-review-and-how-do-i-esca&quot;&gt;What posts should be escalated to staff using [status-review], and how do I escalate them?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;h2&gt;In conclusion&lt;/h2&gt;&#xA;&lt;p&gt;There are already ways to to bring meta posts to more attention, though they are limited to moderator interaction and, while I can understand the reasoning for such a request, we feel that there are sufficient ways for users to get attention to questions on meta sites without needing to add the bounty system to meta sites at this time.&lt;/p&gt;&#xA;" OwnerUserId="122216" LastActivityDate="2021-03-23T13:20:56.100" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

That means allowing somewhat more open-ended questions, for example.&lt;/p&gt;&#xA;&lt;p&gt;At the same time, we need to remember that as time passes by and the community grows bigger the culture changes. From a village to a town to a city. Nevertheless, I think we can preserve this culture. But this requires participation from all the core members of the community, not just the moderators.

If so, what would you do about it as a moderator?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Yes, and I think that women are underrepresented in the mathematical community to begin with. I think it's a problem for the same reason that the low numbers of women in mathematics is a problem.&lt;/p&gt;&#xA;&lt;p&gt;Unfortunately, I don't think there is a lot that a moderator can do about it. We can, should, and presumably do remove content that can be viewed as offensive (e.g. some jokes from the old math jokes thread), and we should try to make the site more hospitable. But having a nice restaurant is not enough to guarantee that people show up to buy the food.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;9&quot;&gt;&#xA;&lt;li&gt;How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;If this is a continuing issue, escalate in the standard procedure of warnings and suspensions.

The solution is simple: open communications. Unless something is in a time crunch, don't override other moderators without discussing it first.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://meta.mathoverflow.net/questions/4947/2021-moderator-election-qa-questionnaire#comment25432_4948&quot;&gt;Tim Campion asked&lt;/a&gt;:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;I understand that you are a moderator and extremely active user at MSE, while also being an active and respected member of the MO community. Could you expand a bit on the similarities and differences between MO and MSE, both in general, and with regard to the way you personally use them? If elected moderator, how would you split your time between the two sites? Also: for how long have you been a moderator at MSE?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Let's start from the top. Both sites are of course sites about mathematics, but MathOverflow is a site [mainly] for professional mathematician. We should, of course, be welcoming to everyone, but the main target crowd is professional mathematicians (academic or otherwise).&lt;/p&gt;&#xA;&lt;p&gt;As such, MO is much more a friendly interaction between colleagues, whereas MSE is closer to office hours, in some extent. (Of course, in reality neither is an accurate description and many exceptions on both ends of the spectrum can be easily found on both sites.)&lt;/p&gt;&#xA;&lt;p&gt;In terms of my personal usage the most striking difference is that I hardly ask questions on MSE at this point. I find it easier to answer questions on MSE, simply by sheer volume of questions and their level (where I can easily pull an answer out of a hat, as opposed to thinking about it for longer in the case of MO).&lt;/p&gt;&#xA;&lt;p&gt;Finally, if elected moderator, the time splitting is not going to be any different. I tend to check both sites very very often most of the time. I will simply have more to interact with on this site, even when there's no new set theory questions for me to look at.&lt;/p&gt;&#xA;&lt;p&gt;I've been a moderator on MSE for just over two and a half years now. I expect the moderation on MO to be very different: less intense in volume, but perhaps more intricate in the subtle issues as dealing with people.&lt;/p&gt;&#xA;" OwnerUserId="7206" LastEditorUserId="7206" LastEditDate="2021-04-04T18:53:44.783" LastActivityDate="2021-04-04T18:53:44.783" CommentCount="19" ContentLicense="CC BY-SA 4.0" />

Of course, this does not mean that questions about &amp;quot;checking my proof of the Riemann hypothesis using antimatter&amp;quot; should be treated with great patience and explanation, but rather that new users are treated with a greater deal of flexibility and forgiveness, treating these as part of the learning process. An analogy: if a new PhD student were to ask a &amp;quot;stupid&amp;quot; or &amp;quot;obvious&amp;quot; question to a well-known and friendly professor in the tea room after a seminar, I would wish the community to react in a similar way that the professor might react.

This could potentially present an issue, since someone like me with no formal prestige to their name moderating this site could give an impression of reduced professionalism at MO to the mathematical community at large.

I had taken all available upper division math and physics classes and maintained a 4.0 by the the end of my first semester as a junior, and the prospect of slowing down for a year and a half to check off 'religion class' boxes rubbed me the wrong way.&lt;/p&gt;&#xA;&lt;p&gt;I do intend to return to academia and complete a PhD, but I would first like to finish what I left college to finish and get a paper submitted for publication. Mathoverflow has been essential for me these past few years; I could not have come as far as I have without the help I've received from members of this site.

It may be that someone who seems to reflect the communities values during the lead-up to an election phase turns out to be a flawed match as the landscape of the community changes, or that someone who was initially a poor choice matures and becomes a paragon of potential moderation.&lt;/p&gt;&#xA;&lt;p&gt;This would also prevent, to some extent, the possibility of attitudes along along the lines of, &amp;quot;I'm a moderator so I don't have to listen to you, you have to listen to me&amp;quot;. Although I haven't seen anything close to this on MO from the current moderators, we are all flawed humans; putting safeguards up against our baser natures is a good idea in my opinion, even if we couldn't imagine falling prey to them.&lt;/p&gt;&#xA;&lt;p&gt;The current moderation team, however, should remain on permanently or until they choose to leave in my opinion. I think everyone currently moderating has given the community ample evidence that they are the kind of moderators we want on this site, and they could serve as an 'old guard' of sorts to help guide newer moderators in the subtle methods of their craft.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;3&quot;&gt;&#xA;&lt;li&gt;There has been extensive discussion on MO Meta on how to make the MathOverflow community more welcoming and inclusive. How do you think the community should approach this issue, and what role (if any) do you think moderators should play in this regard?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;This is something I'm particularly sensitive to due to the situation outlined in my answer to question 1; for the last 3+ years, MO has been my only formal connection to the academic mathematical world and has consequently weighed heavily on my self-image as a mathematician.  If I had a PhD position, or a temporary/permanent job in academia, and I were to suddenly find MO too unwelcoming for me, I could simply turn to the other institutions around me and use them for support. With nowhere else to turn, the times when I felt unwelcome by the community here (which only happened rarely) were extremely disheartening, and could have been rectified pretty simply via the correct type of proactive moderation.&lt;/p&gt;&#xA;&lt;p&gt;I think it is easiest to explain my position using the metaphor of &amp;quot;MO as a tea room for professional mathematicians to discuss research mathematics&amp;quot;. Taking this view, all the regular participants here at MO are standing around a swanky lounge, sipping exotic teas and having scintillating conversation about arcane topics unheard of by the common man. An outsider walks in and is initially blown away by the scale of it all; who knew that things could even get this abstract and complicated! They initially float around a bit, listening in on conversations where perhaps every fifth word makes sense, until they finally reach a point of excitement and offer their first input into the conversation at hand. This is where things can go wrong in the current culture in a way that moderators could fix.&lt;/p&gt;&#xA;&lt;p&gt;Let us assume that their input, whatever it was, was not sufficient to be of interest to anyone else involved in the conversation. The current cultural norm is the equivalent of everyone falling silent for a moment and giving the newcomer a dirty look, before continuing on with the conversation as if they hadn't blurted anything out in the first place. If the newcomer continues to try to offer input, the standard response is increasingly dirtier looks eventually followed by a comment, muttered into someones hand but spoken to the crowd at large, along the lines of 'you don't belong here and you should know that you don't belong here'.&lt;/p&gt;&#xA;&lt;p&gt;Where a moderator can fix this situation, sticking with the above metaphor, is by playing the role of a good host. They could proactively identify newcomers like the one outlined above and glide around the room, close enough to hear them, waiting to see what their input level is. If it becomes apparent that they aren't quite ready to converse in this tea room the moderator could quietly pull them aside, introduce themselves and briefly explain the ethos of the room, then politely suggest other rooms that they might be more comfortable in until they mature to a point where they should return. Also, if something untoward is said before moderators can step in, they could make a point of telling the newcomer that these opinions are not universal -- from someone with a diamond next to their name, comforting words like this can have significant psychological impact. This added personal touch would alleviate much of the perceived unfriendliness in my opinion.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;4&quot;&gt;&#xA;&lt;li&gt;What time zone are you in?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;GMT-5, St. Louis currently, but I'm engaged to be married the 15th of may and we're looking at moving to Ireland so my time zone may change soon.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;5&quot;&gt;&#xA;&lt;li&gt;Assuming a notion of &amp;quot;culture&amp;quot; as explained here, what would a newly elected moderator do to preserve it? Will there be more efforts to preserve the culture, or more to steer it toward things nearer to &amp;quot;what a Stack Exchange forum should be?&amp;quot;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;The kind of 'culture' outlined by Gerhard above is something I think is incredibly valuable and rare here at mathoverflow, and something naturally engendered by the nature of high-level mathematical discussion.&lt;/p&gt;&#xA;&lt;p&gt;I think moderators role in 'culture influence' should, to some extent, require a split personality on the part of the moderator. On the one hand moderators (like Todd for example) are themselves accomplished mathematicians and should be allowed to contribute freely and in an unrestricted capacity as a mathematician on the site, implicitly influencing the cultural norms in the same way we all do by communal participation in them combined with individual evaluations of their significance and importance. On the other hand, as a moderator they should &lt;em&gt;not&lt;/em&gt; strive to directly influence cultural norms &lt;em&gt;beyond their normal capacity as a participant of the site&lt;/em&gt;, and instead strive to allow the community to decide its own culture (with moderators viewed as community participants on equal footing with everyone else). Moderators aren't elected to be tastemakers for the site. This is a delicate line to walk, but I think finding it and balancing is one of the more difficult and important jobs for a prospective moderator.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;6&quot;&gt;&#xA;&lt;li&gt;As MathOverflow is growing, the diversity of the moderator team might become an issue of interest.

We live in a world that is increasingly full of disagreement and refusal to see eye-to-eye; we've already seen some of that enter MO in the form of the recent drama culminating in a suspension.&lt;/p&gt;&#xA;&lt;p&gt;I think that it's incumbent upon moderators to acknowledge this increasing polarity, and proactively make an effort to identify and stamp out any extraneous politicking here to keep things as math-content oriented as possible. It is also important to not simply label any opposing opinions as politicking that must be squashed, but I think that by consulting other moderators and the community at large we should be able to discern a bright red line between friendly discussion and deliberate flaming.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;8&quot;&gt;&#xA;&lt;li&gt;Do you think women are underrepresented in the MO community compared to the mathematical community as a whole? Is this a problem for MO? If so, what would you do about it as a moderator?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;This question doesn't ask us if we think women are underrepresented in math, but wether MO is worse than the math community at large as far as female representation is concerned. I definitely think there are fewer women here than there are in the math community at large; two of my five total professors as an undergrad were women, whereas the proportion of women to men here seems to skew more than 90% in the male direction.&lt;/p&gt;&#xA;&lt;p&gt;I think this is certainly a problem, for the same reason it would be a problem that approximately 50% of the math community was not participating in MO for some reason or another; we aren't hearing input from valuable voices on topics they might be leading experts on in the world.&lt;/p&gt;&#xA;&lt;p&gt;Despite this being a problem for MO, I think it is rooted somewhat in the unfriendliness of online communities towards women in general. I am not aware of any online math/science forum where participation by women approaches 50%, and I would go farther and say that outside of forums specifically dedicated to predominately classically feminine topics males tend to dominate the conversation online.&lt;/p&gt;&#xA;&lt;p&gt;I definitely feel that it is a moderators responsibility to try to alleviate this issue, but the obvious tools at hand seem insufficient to the challenge. I would say that encouraging our female colleagues in real life to participate and making sure to moderate carefully for any shenanigans is probably the most I can think of off the top of my head, but I do think this is a topic worth investing further collaborative thought in for whatever the moderation team is moving forwards.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;9&quot;&gt;&#xA;&lt;li&gt;How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I would begin by alerting them to the situation and asking what their take on the conflict was. If where they're coming from is understandable but they have a brash tone that is creating friction, I might try to keep an eye out for conflicts with other users and step in to clarify positions and de-muddy waters when necessary.&lt;/p&gt;&#xA;&lt;p&gt;On the other hand, if they're coming from somewhere that is ultimately deemed unreasonable or unworkable for the community by myself and other moderators consulted about the user (moderators would presumably be discussing the situation if it was a repeated issue with flags), I would inform them in a firm but friendly manner that the nature of their current interactions with the site are unacceptable and ask them to recalibrate or risk having punitive action taken against them.  If they proceed to cause problems without showing improvement, I would implement short suspensions with explanations initially, and gradually increase the length of suspensions as necessary to get the point across. If nothing seems to work after a significant amount of time trying this process, I would ban the user.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;10&quot;&gt;&#xA;&lt;li&gt;How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I would ask that moderator in private about why they closed the question, and if I disagreed with the closure I would explain why and ask for their take on my opinion. Hopefully we could resolve it between the two of us, either me agreeing that it should have been closed or them agreeing that it can be reopened, but if we're really at a loggerheads I would try to consult other moderators and get a consensus opinion. I would respect whatever that consensus was, irrespective of my own personal opinions.&lt;/p&gt;&#xA;" OwnerUserId="92164" LastActivityDate="2021-03-31T20:12:38.823" CommentCount="9" ContentLicense="CC BY-SA 4.0" />

In which way do you think would you contribute to the diversity of the moderator team?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I honestly do not have a good idea. I do not even know the gender of many of the contributors. As a moderator I would try to keep the contributions/ discussions  strictly academic, where mathematics plays a central role. Abusive and discriminating language should not find a place on this site  in my time here the dialogue has mostly been  like that.  In the few instances when  I noticed that the language became heated the moderators intervened to cool it down and I appreciated that. The issue of underrepresentation    of women and minorities in the mathematical community  is real deserve addressing but I do not feel that MO is the optimal avenue.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;7&quot;&gt;&#xA;&lt;li&gt;What do you see as the biggest challenge for MathOverflow as a site and as a community in the next few years?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;You got me here. I do not know about the costs of maintaining this site  and  about how difficult it would be to maintain the current sources of funding. Since  this site does not deal in controversial issues  I  believe  that the risk of it being polluted/trolled is minimal  but vigilance needs to be maintained. I have noticed that the frequency of homework-like  questions has increased.  This is bad for two reasons: it dilutes the quality of this site and it might  inadvertently make this site complice to the academic  dishonesty that seems to have  grown substantially in campuses during the pandemic.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;8&quot;&gt;&#xA;&lt;li&gt;Do you think women are underrepresented in the MO community compared to the mathematical community as a whole?

If elected, how long do you envision serving as a moderator?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I'm of two minds on this question. Certainly if elected, I would be happy to serve for a finite period of time. I did notice during the nomination phase that several excellent moderator candidates were suggested who declined to run because of the level of responsibility involved. If term lengths were imposed, I suspect that the pool of qualified candidates interested in running would &lt;em&gt;grow&lt;/em&gt; because the commitment would be less open-ended. So if we were to decide that it's desirable to have more rotation on the moderation team, I think that having finite term lengths would probably be an effective strategy.&lt;/p&gt;&#xA;&lt;p&gt;On the other hand, I think the current moderation team does a generally excellent job -- if it ain't broke, why fix it? I would suggest that if term lengths were to be imposed, then we should grandfather in the current moderation team, allowing them to serve indefinitely barring specific issues, or take some similar sort of measures to preserve the benefits of the current system, such as not limiting the &lt;em&gt;number&lt;/em&gt; of terms for which a moderator might serve.&lt;/p&gt;&#xA;&lt;p&gt;On balance, I tentatively think that it would indeed be desirable to have more rotation on the moderation team, much as we do with departmental administrative positions in academia. As I understand it, moderators play several roles in the functioning of MO:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Dealing with flagged posts and problem users.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Facilitating meta discussions by sharing specific information they are privy to.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Leading by example in helping to define the culture of MO.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;(Typically) serving on the board of MO and helping to shape long-term MO strategy.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;For each of these roles, the benefits of cultivating a core of long-serving, experienced moderators are clear, but the benefits of continuously refreshing the workforce are equally clear.&lt;/p&gt;&#xA;&lt;p&gt;In summary, finite term lengths sound like a pretty good idea to me, but only if the benefits of the current stability enjoyed by the moderation team can be maintained.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;3&quot;&gt;&#xA;&lt;li&gt;There has been extensive discussion on MO Meta on how to make the MathOverflow community more welcoming and inclusive. How do you think the community should approach this issue, and what role (if any) do you think moderators should play in this regard?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;In my answer to Question (8) below, I discuss making MO more welcoming to and inclusive of women and other underrepresented groups. Much of what I say there is applicable here: moderators can lead by example, be gentle to newcomers, and take corrective action when others fall short of such standards. Moderators can also do things like help new users to clean up their questions to make them more palatable to the MO audience. Most of these measures are not specific to moderators, but a moderator's actions in such regards do carry extra weight.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;4&quot;&gt;&#xA;&lt;li&gt;What time zone are you in?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I am in EST (UTC-5)/EDT (US Eastern time zone). This will continue to be the case when I change positions in the fall.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;5&quot;&gt;&#xA;&lt;li&gt;Assuming a notion of &amp;quot;culture&amp;quot; as &lt;a href=&quot;https://meta.mathoverflow.net/questions/908/2013-moderator-election-qa-question-collection/918#918&quot;&gt;explained here&lt;/a&gt;, what would a newly elected moderator do to preserve it? Will there be more efforts to preserve the culture, or more to steer it toward things nearer to &amp;quot;what a Stack Exchange forum should be?&amp;quot;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I have difficulty parsing the description of &amp;quot;culture&amp;quot; discussed by Gerhard at the linked post, but I take this to be a question about some of the unique aspects of the culture at MO setting us apart from other SE sites. To be honest, I have only limited familiarity with other SE sites, so I don't have a deep grasp of which aspects of our culture stand in contrast to them. MO's situation is of course unique in that we were founded independently from SE and continue to be an independent entity hosted on the SE network. We have cultivated a space specifically for research mathematics, which is fantastically valuable. Compared to other sites, this makes our community more &amp;quot;targeted&amp;quot;, which has allowed us, for instance, to welcome more open-ended questions than are typically permitted on other sites. These aspects of our culture are to be treasured.&lt;/p&gt;&#xA;&lt;p&gt;Perhaps this is an appropriate place to say something about our relationship with the SE network more broadly. I feel that the relationship could use a bit more structure. For instance, when SE &lt;a href=&quot;https://meta.mathoverflow.net/questions/3976/mathoverflow-updated-site-theme-is-ready-for-testing&quot;&gt;redid the theme of the site&lt;/a&gt; last year, and when they announced the new &lt;a href=&quot;https://meta.mathoverflow.net/questions/4858/nudge-the-new-stacks-editor-has-significant-implications-for-this-site&quot;&gt;rich text editor&lt;/a&gt; a few months ago, I felt we were caught both times a bit flat-footed. For instance, it's been a year, and we still haven't implemented a background color for the site in the new theme! One measure I think could help would be to have a specific individual MO user (a moderator or otherwise) designated as the &amp;quot;point person&amp;quot; for communication with SE. We would expect this person to be given a heads-up about major changes like these two before they were publicly announced, and this person would have the authority &amp;quot;make official requests&amp;quot; about such matters from the MO community to SE.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;6&quot;&gt;&#xA;&lt;li&gt;As MathOverflow is growing, the diversity of the moderator team might become an issue of interest. As I understand, the present moderators have much in common, and women are, to say it that way, underrepresented. In which way do you think would you contribute to the diversity of the moderator team?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I've spoken about the value of diversity in the moderator team in answer to (2) above. In many respects I would be a regressive moderator choice as regards diversity. One aspect I do bring to the table concerns my early years on MO. I joined MO within a few months of its founding, and for many years was mostly a lurker on the site, before becoming increasingly active as I've matured mathematically. But in those early years, I was between my undergraduate and graduate school, working in industry, and not sure what role math would play in my future. MO was instrumental in helping me sustain my interest in mathematics and eventually return to academia. So I do bring a bit of an outsider's perspective.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;7&quot;&gt;&#xA;&lt;li&gt;What do you see as the biggest challenge for MathOverflow as a site and as a community in the next few years?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I think things have been working pretty well for many years now. The balance of questions on this questionnaire suggests that issues of inclusiveness and diversity in our community are on many people's minds. I agree that such issues should be at the forefront of discussions about the future of MO going forward.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;8&quot;&gt;&#xA;&lt;li&gt;Do you think women are underrepresented in the MO community compared to the mathematical community as a whole? Is this a problem for MO? If so, what would you do about it as a moderator?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I object to one premise of the question. Women (as well as numerous other demographic groups) are underrepresented in mathematics as a whole, and this is an issue for mathematics as a whole. The question asks about the extent to which the problem is &lt;em&gt;worse&lt;/em&gt; on MO than in mathematics as a whole; I believe it is a nonzero extent, but &lt;em&gt;it doesn't matter&lt;/em&gt;. MO is part of the mathematics community, and as such, any problem for the mathematics community is a problem for MO.&lt;/p&gt;&#xA;&lt;p&gt;As a moderator, there are various things to do in terms of leading by example in being welcoming to newcomers, which we've discussed &lt;em&gt;ad nauseum&lt;/em&gt; over the past few months. One thing we haven't done is to &lt;em&gt;systematically seek out women&lt;/em&gt; (and members of other underrepresented demographic groups) and &lt;em&gt;ask them&lt;/em&gt; about MO. In dealing with problems of underrepresented groups, it doesn't seem very productive to me to have those who &lt;em&gt;are&lt;/em&gt; represented bandying about ideas bout addressing such issues. I think it's high time we do something a little more proactive -- perhaps create some sort of survey or something like that. This is the sort of thing that a moderator's behind-the-scenes role could be helpful in facilitating.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;9&quot;&gt;&#xA;&lt;li&gt;How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I suspect the current moderation team has some internal guidelines on such matters, to which I would defer. Common sense says that the user should be contacted privately with a gentle explanation of the problems with their conduct and suggestions on how to fix them, gradually escalating if necessary to more formal interventions like suspensions.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;10&quot;&gt;&#xA;&lt;li&gt;How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Again I suspect the current moderation team has their own well-established norms on such matters, to which I would defer.

If elected, how long do you envision serving as a moderator?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Two years seems like a fair amount of time for a newly elected moderator, upon which the moderator may choose to re-run or leave the post. For moderators that have been on the site for many years, I believe the situation may be different, and community may already have absolute trust in their abilities, in which case a probation period may not longer be necessary.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;3&quot;&gt;&#xA;&lt;li&gt;There has been extensive discussion on MO Meta on how to make the MathOverflow community more welcoming and inclusive. How do you think the community should approach this issue, and what role (if any) do you think moderators should play in this regard?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;This issue is of course still outstanding in other sites, such as the sister site math.SE. It is surely impossible to guarantee hundreds of thousands of users are constantly behaving in a civil fashion, but I believe as moderators we should set the example, such as looking out for posts by new users (highlighted by the system) and making sure that if one of us (moderator or otherwise) has interacted with the user, such interaction has indeed been welcoming and civil. In a site such as MO, where professionals interact, there is definitely no place for disrespect, intolerance, or other such behaviour.&lt;/p&gt;&#xA;&lt;p&gt;At the same time, some users may come off as terse or unkind even if there is not ill-will: it is hard to communicate through text, where the nuance of spoken word is lost. Because of this, moderators should be ready to mediate interactions between new users and existing users that may have escalated due to a simple misunderstanding. This does happen often and, quite likely, more often that the former situation.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;4&quot;&gt;&#xA;&lt;li&gt;What time zone are you in?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;At the moment, I am in GMT+01:00 (Irish Standard Time).&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;5&quot;&gt;&#xA;&lt;li&gt;Assuming a notion of &amp;quot;culture&amp;quot; as &lt;a href=&quot;https://meta.mathoverflow.net/questions/908/2013-moderator-election-qa-question-collection/918#918&quot;&gt;explained here&lt;/a&gt;, what would a newly elected moderator do to preserve it? Will there be more efforts to preserve the culture, or more to steer it toward things nearer to &amp;quot;what a Stack Exchange forum should be?&amp;quot;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Each community in SE has its own ways and its own idiosyncrasies, in particular when it comes to commenting, answering and weighing on the value of these interactions. As long as these have positive outcomes and do not produce a harmful environment, the community is free to find its own way.&lt;/p&gt;&#xA;&lt;p&gt;For example, more experienced users tend to be reticent on giving an answer when they deem it &amp;quot;easy enough&amp;quot; or &amp;quot;well known&amp;quot;, which is not useful for record-keeping. As a moderator in math.SE, I usually kindly request such comments be made into answers. If this does not work (for whatever reason, which is at any rate irrelevant) I tend to cite these replies and add them to the answers as community wiki. This helps the site keep track of those questions that have been answered, and avoid duplication.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;6&quot;&gt;&#xA;&lt;li&gt;As MathOverflow is growing, the diversity of the moderator team might become an issue of interest. As I understand, the present moderators have much in common, and women are, to say it that way, underrepresented. In which way do you think would you contribute to the diversity of the moderator team?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I do not know the moderators personally, so I'll just tell you a bit about myself. I am from Argentina, where I spent most of my formative years, graduated from a public university where students from multiple backgrounds are educated, and where I also worked as a teacher assistant. I also worked part-time in a private university where I taught math for students without a mathematical background. I emigrated to Ireland almost four years ago. I have been working with undergraduate students in Ireland for the last four years, taught around 24 courses during this time as a TA, and had the opportunity to (if perhaps briefly) interact with hundreds of students from many different countries and backgrounds. This has helped me become more aware of existing diversity issues, and learn how to help students (and in this case, users) have a better experience.&lt;/p&gt;&#xA;&lt;p&gt;On another level, I have actively participated in many mathematics-related events in Europe and South America where I (usually indirectly) learned from organizers about how to foster diversity in such events. I most strongly believe that MO should be a place where every mathematician (or mathematics-adjacent professional) feels welcome to participate, and I am ready to contribute to this effort.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;7&quot;&gt;&#xA;&lt;li&gt;What do you see as the biggest challenge for MathOverflow as a site and as a community in the next few years?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Certain interactions I have had in the past make me believe a large amount of mathematics-adjacent internet users have a negative (or very negative) opinion of MO and the sister site math.SE, in particular with regards to the experience of new users, for example, and the way these users are treated. It would be good to understand how we can help improve the image of the site (and not in a cosmetic way!), specially if future professional mathematicians have such view of the site.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;8&quot;&gt;&#xA;&lt;li&gt;Do you think women are underrepresented in the MO community compared to the mathematical community as a whole? Is this a problem for MO? If so, what would you do about it as a moderator?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Compared to workshops, conferences and other similar events (where in many cases they are still underrepresented), women participate in MO much less than usual: by looking at the first few pages of users, organized by reputation, where almost all users have public names, one can count exactly one username with an identifiable female name out of about 300+. This is of course an issue in that many early researchers miss out on using the forum (assuming they would agree using the forum is a good use of their time!), while MO misses out on the invaluable input it could receive from the many leading experts that are not participating.&lt;/p&gt;&#xA;&lt;p&gt;The site has established itself as an important piece of the mathematical community to many, and I believe we should make sure it keeps up to the standard we would expect from workshops, say, and does its best to attract mathematicians independent of their background. I would like to help with the efforts.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;9&quot;&gt;&#xA;&lt;li&gt;How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;We have dealt with this issue in math.SE a few times (I have been a moderator there for about 7 years). Sometimes the user did improve their behaviour after we contacted them and made them aware of the issue, making it clear that we valued their input to the site but that we could not tolerate disruptive behaviour. Sometimes we had to escalate and suspend them. As any other site, there's a code of conduct, and every user ---independent of their prowess--- should adhere to it.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;10&quot;&gt;&#xA;&lt;li&gt;How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;This has also happened a few times in math.SE. The moderators involved should discuss the matter privately, and aim to come to an agreement. If no agreement is reached, I believe moderators should withdraw from the situation and let the community decide.&lt;/p&gt;&#xA;&lt;p&gt;Ideally, this kind of situation would not happen regularly, and I believe moderators should be the last ones to decide to close a question, and let trusted users do the voting. After all, moderators can take unilateral action, and this (if not always, quite often) leads to discussion unless the course of action is clear cut (say if a user posted spam, or a solution to an open problem which is clearly bogus.)&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Could you expand a bit on the similarities and differences between MO and MSE, both in general, and with regard to the way you personally use them? If elected moderator, how would you split your time between the two sites?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Both forums are similar in their Q&amp;amp;A format, the more experienced users from math.SE are either professional mathematicians, educators, former mathematicians, or a mix of these, as it happens in MO. The main difference is the influx math.SE experiences from new users that are very unfamiliar with the way the site works, use of LaTeX, and other issues, and the level of the questions, along with a perhaps more collegial environment in MO.&lt;/p&gt;&#xA;&lt;p&gt;In this way, math.SE requires more intense moderator activity, which is backed up by many highly active users that help with the efforts, while MO tends to see just a handful of &amp;quot;lost&amp;quot; users and perhaps sometimes more serious issues that have to be dealt with.&lt;/p&gt;&#xA;&lt;p&gt;I enjoy using math.SE to provide help to people that are learning a subject and, perhaps less than before, to get some help on non-research level questions that I bump into every now and then. During last year of my PhD, I started using it very little, answering questions seldomly. I use MO to consult with experts and try to find answers to questions that may appear during my research, though I have used it very passively lately, and read rather than contribute with answers. I am looking forward to spending more time on the site, and hopefully contributing to it more meaningfully.&lt;/p&gt;&#xA;" OwnerUserId="21326" LastEditorUserId="21326" LastEditDate="2021-04-05T09:04:24.553" LastActivityDate="2021-04-05T09:04:24.553" CommentCount="5" ContentLicense="CC BY-SA 4.0" />

The general overview is that you can rank as many of the candidates as you wish, in the order you prefer. Your first choice candidate will get your vote first and that vote will stay with them until one of two things happens:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;your candidate is eliminated&lt;/li&gt;&#xA;&lt;li&gt;your candidate reaches the threshold to be elected.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;Should your top candidate be eliminated, your vote will then be transferred to the second-highest ranked candidate who remains in the election. Should the candidate reach the threshold, a fractional amount of your vote proportional to the overage being reallocated to other candidates will be awarded to your next-highest ranked candidate who remains in the election.&lt;/p&gt;&#xA;&lt;p&gt;This process will continue until three candidates have reached the threshold.&lt;/p&gt;&#xA;&lt;p&gt;Up until this very election, we only allowed voters to rank the top three candidate selections and this led to a potential for gaming the ranks - if you were certain that your favorite would win election, you might opt to rank them third - or not at all - which could cause a spoiler effect where your top candidate doesn't end up being elected at all. While unlikely, this is a known issue with all STV formats but by allowing you to rank all candidates rather than only three, we're hoping to &lt;em&gt;reduce&lt;/em&gt; the effect since you will have less reason to not rank your top choice first.&lt;/p&gt;&#xA;&lt;p&gt;The other caveat is that you should &lt;em&gt;&lt;strong&gt;only rank candidates you wish to win the election&lt;/strong&gt;&lt;/em&gt; do not rank a candidate who you feel is a bad choice for the position!

One might define the equivalence relation whereby element &lt;span class=&quot;math-container&quot;&gt;$a$&lt;/span&gt; in structure &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt; is equivalent to element &lt;span class=&quot;math-container&quot;&gt;$b$&lt;/span&gt; in structure &lt;span class=&quot;math-container&quot;&gt;$B$&lt;/span&gt; exactly when there is an isomorphism of &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt; to &lt;span class=&quot;math-container&quot;&gt;$B$&lt;/span&gt; taking &lt;span class=&quot;math-container&quot;&gt;$a$&lt;/span&gt; to &lt;span class=&quot;math-container&quot;&gt;$b$&lt;/span&gt;. This results in what I have called the &lt;em&gt;isomorphism orbit&lt;/em&gt; of the object &lt;span class=&quot;math-container&quot;&gt;$a$&lt;/span&gt; in &lt;span class=&quot;math-container&quot;&gt;$A$&lt;/span&gt;.&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/7RiRZ.jpg&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/7RiRZ.jpg&quot; alt=&quot;enter image description here&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;According to some accounts of the philosophy of abstract structuralism, what a mathematical object is, is the structural role that it plays in abstract mathematical structures.&lt;/p&gt;&#xA;&lt;p&gt;The problem for this view arises with nonrigid mathematical structures such as the complex field &lt;span class=&quot;math-container&quot;&gt;$\newcommand\C{\mathbb{C}}\C$&lt;/span&gt;.&lt;/p&gt;&#xA;&lt;p&gt;Here is how I describe the situaiton is my book, &lt;a href=&quot;http://jdh.hamkins.org/lectures-on-the-philosophy-of-mathematics&quot; rel=&quot;nofollow noreferrer&quot;&gt;Lectures on the Philosopy of Mathematics (MIT Press)&lt;/a&gt;&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Although one conventionally describes &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; as &amp;quot;the square root of negative one,&amp;quot; nevertheless one might reply to this, ``Which one?'' in light of the fact that &lt;span class=&quot;math-container&quot;&gt;$\newcommand\unaryminus{-}\unaryminus i$&lt;/span&gt; also is such a root:&#xA;&lt;span class=&quot;math-container&quot;&gt;$$(\unaryminus i)^2=(\unaryminus 1\cdot i)^2=(\unaryminus 1)^2i^2=i^2=\unaryminus 1.$$&lt;/span&gt;&#xA;Indeed, the complex numbers admit an automorphism, an isomorphism of themselves with themselves, induced by swapping &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; with &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt;---namely, complex conjugation:&#xA;&lt;span class=&quot;math-container&quot;&gt;$$z=a+bi\qquad\mapsto\qquad\bar z= a-bi.$$&lt;/span&gt;&#xA;The conjugation map preserves the field structure, since &lt;span class=&quot;math-container&quot;&gt;$\overline{y+z}=\bar y+\bar z$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\overline{y\cdot z}=\bar y\cdot\bar z$&lt;/span&gt;, and therefore the complex field is not a rigid mathematical structure. Since conjugation swaps &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt;, it follows that &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; can have no structural property in the complex numbers that &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt; does not also have. So there can be no principled, structuralist reason to pick one of them over the other. Is this a problem for structuralism? It does seem to be a problem for singular terms, since how do we know that the &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; appearing in my calculations this week is the same number as what will appear in your calculations next week? Perhaps my &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; is your &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt;, and we do not even realize it.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;If one wants to understand mathematical objects as abstract positions within a structure, as in abstract structuralism, then one must grapple with the fact that in light of the conjugation automorphism, the numbers &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt; play exactly the same roles in this structure (see Shapiro, 2012). The numbers &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt; have the same isomorphism orbit with respect to the complex field, and so in this sense, although distinct, they each play exactly the same structural role in &lt;span class=&quot;math-container&quot;&gt;$\C$&lt;/span&gt;. This would seem to undermine the idea that mathematical objects &lt;em&gt;are&lt;/em&gt; abstract positions in a structure, since we want to regard these as distinct complex numbers.&lt;/p&gt;&#xA;&lt;p&gt;The point is that one cannot understand the mathematical objects as identical to the structural roles that they play within a system, since &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt; play exactly the same role in &lt;span class=&quot;math-container&quot;&gt;$\C$&lt;/span&gt; as each other, yet are to be regarded as distinct complex numbers.&lt;/p&gt;&#xA;&lt;p&gt;In fact, there is nothing special about the numbers &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt; in this argument. For example, the numbers &lt;span class=&quot;math-container&quot;&gt;$\sqrt{2}$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\unaryminus\!\sqrt{2}$&lt;/span&gt; also happen to play the same structural role in the complex field &lt;span class=&quot;math-container&quot;&gt;$\C$&lt;/span&gt;, because there is an automorphism of &lt;span class=&quot;math-container&quot;&gt;$\C$&lt;/span&gt; that swaps them (although one uses the axiom of choice to prove this). Contrast this  with the real field &lt;span class=&quot;math-container&quot;&gt;$\newcommand\R{\mathbb{R}}\R$&lt;/span&gt;, where &lt;span class=&quot;math-container&quot;&gt;$\sqrt{2}$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\unaryminus\!\sqrt{2}$&lt;/span&gt; are of course discernible, since one is positive and the other is negative, and the order is definable from the field operations in &lt;span class=&quot;math-container&quot;&gt;$\R$&lt;/span&gt; via &lt;span class=&quot;math-container&quot;&gt;$x\leq y\iff\exists u\ x+u^2=y$&lt;/span&gt;. It follows that the real number field is not definable in the complex field by any assertion in the language of fields. In fact, there is an enormous diversity of automorphisms of the complex field; one may move &lt;span class=&quot;math-container&quot;&gt;$\sqrt[3]{2}$&lt;/span&gt;, for example, to one of the nonreal cube roots of &lt;span class=&quot;math-container&quot;&gt;$2$&lt;/span&gt;, such as &lt;span class=&quot;math-container&quot;&gt;$\sqrt[3]{2}(\sqrt{3}i-1)/2$&lt;/span&gt;. Therefore, the numbers &lt;span class=&quot;math-container&quot;&gt;$\sqrt[3]{2}$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\sqrt[3]{2}(\sqrt{3}i-1)/2$&lt;/span&gt; are indiscernible in the complex field---there is no property expressible in the language of fields that will distinguish them. Indeed, except for the rational numbers, every single complex number is part of a nontrivial orbit of automorphic copies, from which it cannot be distinguished in the field structure. So the same issue as with &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt; occurs with every irrational complex number. For this reason, it is problematic to try to identify complex numbers with the abstract positions or roles that the numbers play in the complex field.&lt;/p&gt;&#xA;&lt;p&gt;Meanwhile, one may recovers the uniqueness of the structural roles simply by augmenting the complex numbers with additional natural structure. Specifically, once we augment the complex field &lt;span class=&quot;math-container&quot;&gt;$\C$&lt;/span&gt; with the standard operators for the real and imaginary parts:&#xA;&lt;span class=&quot;math-container&quot;&gt;$$\text{Re}(a+bi)=a\qquad\qquad\text{Im}(a+bi)=b,$$&lt;/span&gt;&#xA;then the expanded structure &lt;span class=&quot;math-container&quot;&gt;$\langle\C,+,\cdot,\text{Re},\text{Im}\rangle$&lt;/span&gt; becomes &lt;em&gt;rigid&lt;/em&gt;, meaning that it has no nontrivial automorphisms. Thus, every complex number plays a unique structural role in this new structure, which is Leibnizian. This additional structure is implicit in the complex plane conception of the complex numbers, which is part of why the number &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt; appears fine as a singular term---it refers to the point &lt;span class=&quot;math-container&quot;&gt;$(0,1)$&lt;/span&gt; in the complex plane---whereas &lt;span class=&quot;math-container&quot;&gt;$\unaryminus i$&lt;/span&gt; refers to &lt;span class=&quot;math-container&quot;&gt;$(0,-1)$&lt;/span&gt;. The complex plane is not merely a field, for it carries along its coordinate information by means of the real-part and imaginary-part operators, making it rigid. In the complex plane, every complex number plays a different role.&lt;/p&gt;&#xA;" OwnerUserId="1946" LastActivityDate="2021-04-06T19:40:05.813" CommentCount="5" ContentLicense="CC BY-SA 4.0" />

Currently, when I go to close-vote a question I see the following pop-up menu:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/mbyXW.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/mbyXW.png&quot; alt=&quot;&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;If I click the second option (as most close-voters usually do in my experience) I am presented with the following menu:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/MzkvD.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/MzkvD.png&quot; alt=&quot;&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;Now, if I feel like the question belongs on math stackexchange in its current format I would typically click the second option above -- I just recently found out that this is the &lt;em&gt;incorrect course of action to get the question migrated in its current format&lt;/em&gt;. To achieve that, I should have been clicking the third option above labeled 'This question belongs on another site in the stackexchange network', bringing up the following menu:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/4uU5A.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/4uU5A.png&quot; alt=&quot;enter image description here&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;From here, if I click the second option and vote to close (and at least two other voters do as well) the question will, upon recieving it's fifth close vote, immediately be migrated to math stackexchange in its current format with all answers and net-positive vote scores intact, and any net-negative vote scores reset to &lt;span class=&quot;math-container&quot;&gt;$0$&lt;/span&gt;. (also any associated rep gains here will be wiped and transferred over to math stackexchange).&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;This seems, to me, a very counterintuitive system.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Why is there an option to vote that something 'belongs on math stackexchange', which then just closes the question here?&lt;/li&gt;&#xA;&lt;li&gt;Why is this option the easy one to find, while the option that actually migrates the question is hidden behind an additional pop-up menu?&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;I see two potential options to make things more intuitive:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;We change the menu so that the obvious option in the second pop-up menu (that everyone clicks when they want a question migrated) actually migrates the question if it receives &lt;span class=&quot;math-container&quot;&gt;$\geq$&lt;/span&gt;3 votes, and we eliminate the (after implementing the first suggestion) redundant second option in the third pop-up menu. We should also add language explicitly explaining how the migration process works to this option.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;We keep the second option in the second menu as is, and use it to close questions that belong on math stackexchange but need imporvement from the OP before they're suitable and consequently shouldn't be migrated as is. We also move the migration option to the second pop-up menu so it's on equal footing with the close option, however, and we add language explicitly explaining the difference between the two options: one is for questions that are fine on math stackexchange as-is and should be teleported over there instantly, and one is for questions with appropriate content but requiring significant editorializing before they are appropriate for migration.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;Those of us feeling particularly generous could even edit the question to make it appropriate, then vote to migrate it. Although there may be concerns about low-quality migrations happening more often, in my experience when people feel a question is also too low-level for math stackexchange they will simply click the first option in the second menu (and alert the OP if they want to be nice), avoiding undesirable question migration.&lt;/p&gt;&#xA;" OwnerUserId="92164" LastEditorUserId="92164" LastEditDate="2021-04-19T01:12:39.803" LastActivityDate="2021-04-19T01:12:39.803" Title="Proposing a change to the close-vote interface" Tags="|discussion|feature-request|vote-to-close|" AnswerCount="1" CommentCount="14" ContentLicense="CC BY-SA 4.0" />

This is because migration is only appropriate in very specific circumstances, but to the casual MO user (even one with enough rep to vote on closures), this is generally initially unclear -- it makes a lot of intuitive sense that migration should be appropriate much more commonly. In actuality, the circumstances are so rare that it is scarcely worth trying to educate all MO users on the esoteric circumstances appropriate for migration -- we all have more pressing concerns on the site. So it seems appropriate for the actual migration option to remain almost an easter egg which is counterintuitive to find.

We don't have a flood of questions under these tags, but for several reasons I think it would also be appropriate for us to have a bit more guidance on meta about when exactly it's appropriate to ask questions which would fall under such tags:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Career and advice questions are not about mathematics &lt;em&gt;per se&lt;/em&gt;, which certainly puts such questions outside the central aim of MO's scope.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Giving really good career advice requires knowing more about someone's situation than is typically appropriate to post publicly on the internet. So by entertaining such questions, we risk giving misleading answers. There's even a real possibility of harm in doing so.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Relatedly, good career advice has limited generalizability beyond the situation of the individual questioner.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;There is perhaps a place for giving &amp;quot;general advice&amp;quot; or &amp;quot;rules of thumb&amp;quot;, as one might give to a mathematician in any private setting. But the public nature of MO and the absence of various contextual information about a questioner's situation which is normally taken for granted in other similar &amp;quot;advice-giving&amp;quot; situations I think means that one should at least approach giving advice on MO a bit differently than one might be accustomed to. It is worth spelling out what some of these differences are.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Besides reminding advice-seekers to talk to people they know and not just strangers on the internet, it's possible that there are other places on the internet more suitable for various kinds of advice questions than here. It may be worth compiling a list of such places.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://meta.stackexchange.com/questions/110852/where-can-you-ask-about-career-advice&quot;&gt;Here&lt;/a&gt; is a general Meta SE question on where in the network certain &amp;quot;career advice&amp;quot;-type questions are acceptable.&lt;/p&gt;&#xA;&lt;p&gt;So my &lt;strong&gt;Questions&lt;/strong&gt; are:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Are &amp;quot;career advice&amp;quot; questions ever suitable for MO?&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If so, under what circumstances?&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Conversely, under what circumstances are &amp;quot;career advice&amp;quot; questions &lt;em&gt;not&lt;/em&gt; suitable for MO?&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;If a &amp;quot;career advice&amp;quot; question is suitable for MO and one decides to answer it, what special considerations should one keep in mind in doing so?&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;As a final note, I think perhaps the &lt;em&gt;status quo&lt;/em&gt; is that such questions are likely to be closed, but before closure they are not unlikely to attract comments or even answers which do provide the requested advice, and so the question may serve its intended purpose anyway.&lt;/p&gt;&#xA;&lt;ol start=&quot;5&quot;&gt;&#xA;&lt;li&gt;Is the &lt;em&gt;status quo&lt;/em&gt; as I described it a workable way to approach these matters?&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;P.S.

Is there a way to retrieve your questions? From what I've read, this is possible as long as you have kept the link to your questions. But could it be that after (say) a year, they are completely erased and totally un-retrievable? I don't know if that could happen or not, but better be safe than sorry. Other scenarios are possible too, such as StackExchange closing down all operations, or being hacked or victim of a computer glitch, and resulting in content loss.&lt;/p&gt;&#xA;&lt;p&gt;In my case, my posting frequency has decreased a lot recently, meaning that I post elsewhere most of the time these days (outside stackexchange), or re-post previous questions elsewhere mostly on my own blog).

If my previous question that required so much time to produce brings no value to the community, I understand it gets closed / removed, and I have no motivation to post such questions in the future (which is great too for MO), as it also brings no value to me, creating a feeling of giving without receiving anything back.&lt;/p&gt;&#xA;&lt;p&gt;In short, I am just wondering if I should save in the cloud all the material (of value to me) that I will or have ever published on MO, or in other StackExchange channels.&lt;/p&gt;&#xA;" OwnerUserId="140356" LastActivityDate="2021-05-15T06:43:20.003" Title="How to make sure your questions never disappear in a blackhole?"

As explained in the &lt;a href=&quot;https://meta.stackexchange.com/q/344513&quot;&gt;March 2020 announcement of this feature&lt;/a&gt;, there is a standard Stack Exchange boilerplate wording for this advice, but the wording can be customized on a per-site basis.&lt;/p&gt;&#xA;&lt;p&gt;On MathOverflow, we haven't yet gotten around to customizing this modal window, as Martin Sleziak gently reminded us in a &lt;a href=&quot;https://meta.mathoverflow.net/questions/4806/customize-the-modal-window-for-the-first-time-askers&quot;&gt;meta post&lt;/a&gt; a few months ago. Martin's question is thorougly-researched and contains a wealth of information on the matter, including screenshots illustrating what we're talking about, and I refer there, as well as an &lt;a href=&quot;https://chat.stackexchange.com/rooms/9369/conversation/customizing-the-modal-window&quot;&gt;accompanying discussion in the MathOverflow chatroom&lt;/a&gt; for further background. In the discussion on Martin's question, a consensus was quickly reached that that we certainly &lt;em&gt;should&lt;/em&gt; customize this modal window. The intention of the current question is to close the loop and settle on the precise wording and formatting of the modal window. Once we have done so, the next step is simply for the mods to tag this question &lt;a href=&quot;https://mathoverflow.net/questions/tagged/status-review&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;status-review&amp;#39;&quot; rel=&quot;tag&quot;&gt;status-review&lt;/a&gt;, sending it down the Stack Exchange pipeline.&lt;/p&gt;&#xA;&lt;p&gt;In an &lt;a href=&quot;https://meta.mathoverflow.net/a/4815/2362&quot;&gt;answer&lt;/a&gt; to his question, Martin also provided a concrete proposal for what this wording and formatting should be, taking into account the wording of similar modal windows on other sites, the specifics of MathOverflow, and numerous suggestions from the comments. Martin's proposal reads as follows:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;To improve the chances of your question getting an answer make sure that it:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Is about mathematics at &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;graduate or higher level&lt;/a&gt;. (Use &lt;a href=&quot;https://meta.mathoverflow.net/q/3760&quot;&gt;other sites&lt;/a&gt; for general mathematical questions.)&lt;/li&gt;&#xA;&lt;li&gt;Includes the necessary background and has an informative title. (See also: &lt;a href=&quot;https://meta.mathoverflow.net/q/882&quot;&gt;How to write a good MathOverflow question?&lt;/a&gt;)&lt;/li&gt;&#xA;&lt;li&gt;Is properly formatted - use &lt;a href=&quot;https://meta.mathoverflow.net/q/3763&quot;&gt;MathJax (TeX-like syntax)&lt;/a&gt; for writing mathematics.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Before you post, &lt;a href=&quot;https://mathoverflow.net/search&quot;&gt;search the site&lt;/a&gt; to make sure your question hasn’t been answered&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Summarize the problem&lt;/li&gt;&#xA;&lt;li&gt;Provide details and any research&lt;/li&gt;&#xA;&lt;li&gt;When appropriate, describe what you’ve tried&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;&lt;strong&gt;Note 1:&lt;/strong&gt; As discussed in Martin's answer, &lt;a href=&quot;https://chat.stackexchange.com/transcript/message/56757085#56757085&quot;&gt;the wording in the last 3 bullet points comes from SE and cannot be changed&lt;/a&gt; (although the third one can be omitted if needed).&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Note 2:&lt;/strong&gt; There is no hard limit to the length of the modal window, but by its nature it should of course not be too long. Certainly it should be no longer than the one on &lt;a href=&quot;https://english.stackexchange.com/&quot;&gt;English Language and Usage&lt;/a&gt;, which looks like &lt;a href=&quot;https://i.stack.imgur.com/u04uO.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;this&lt;/a&gt;, and probably closer to the length of the modal window for &lt;a href=&quot;https://math.stackexchange.com/&quot;&gt;Math.SE&lt;/a&gt;, which looks like &lt;a href=&quot;https://i.stack.imgur.com/Tknmd.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;this&lt;/a&gt;.

Should it be exactly as Martin Sleziak has proposed? Should it be a slight variant of his proposal? Should it be something else altogether?&lt;/p&gt;&#xA;&lt;p&gt;Some possibilities of changes might include reordering some of the list items, tinkering with key words such as &amp;quot;graduate-level&amp;quot; (which was already changed from &amp;quot;research-level&amp;quot; so as not to clash with the later use of &amp;quot;research&amp;quot; in the non-customizable portion of the text), etc. Suggestions from the comments on Martin's question which didn't make it into his proposal due to controversy or to length limitations include some kind of admonishment against simultaneous cross-posting or some kind of link to Math.SE.&lt;/p&gt;&#xA;" OwnerUserId="2362" LastEditorUserId="157144" LastEditDate="2021-06-17T15:43:12.213" LastActivityDate="2021-06-17T15:43:12.213" Title="What should the modal window for first-time askers say?"

To quote Joonas, if you're considering cross-posting, you should do the following:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;Wait several days, not just hours. I would suggest a week.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;That is, it is &lt;em&gt;only&lt;/em&gt; appropriate to cross-post if you have waited some time after your first post and have not received any answers or have received only unsatisfactory answers. Be patient, and wait for results before cross-posting.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;ol start=&quot;2&quot;&gt;&#xA;&lt;li&gt;Provide links between the two versions.

Not only are the scopes different, but also the communities value different kinds of background information.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;As a corollary, you should revise your post to meet the norms of the community you are cross-posting it to.&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;You should not cross-post instantaneously.&#xA;If you realized that you asked in the wrong place and there are no answers yet, simply delete the old one and ask in the right place.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;However, if you &lt;em&gt;have&lt;/em&gt; received comments or answers on your question, it is rude to delete the old question and cross-post elsewhere.&lt;/p&gt;&#xA;&lt;p&gt;Finally, you should also consider the policies of the other site you're posting to regarding cross-posting.

Although we are hosted on the &lt;a href=&quot;https://en.wikipedia.org/wiki/Stack_Exchange&quot; rel=&quot;nofollow noreferrer&quot;&gt;Stack Exchange network&lt;/a&gt;, we were founded independently and continue to be an independent entity. I'm pretty sure we pre-date the existence of &lt;a href=&quot;https://math.stackexchange.com/&quot;&gt;Mathematics Stack Exchange&lt;/a&gt;, for instance. We've had this name, and the associated logo and so forth, since 2009.&lt;/p&gt;&#xA;&lt;p&gt;None of this is precisely relevant to the valid concerns you bring up about the regular opportunities for confusion about the purpose of the site suggested by the name. But what I'm trying to express is that I, and I'm certain many others, would be extremely reluctant to change the name of the site after all these years.&lt;/p&gt;&#xA;&lt;p&gt;Moreover, my sense is that almost any conceivable name would have similar issues.

The difficulty is communicating (3). Part of the problem is that the majority of people looking for answers to mathematical questions on the internet &lt;em&gt;don't even have any idea that there is such a thing as research-level mathematics&lt;/em&gt;! Even if they do possess such a concept, the idea that there's a sleek, modern Q&amp;amp;A site devoted to something so niche and that &lt;em&gt;that's&lt;/em&gt; what they've stumbled across it is probably quite surprising. In fact, it's an open problem, even after all these years, to adequately communicate (3) in one or a few &lt;em&gt;sentences&lt;/em&gt;, and we continue to have internal debate about it -- for just one recent example, see discussion &lt;a href=&quot;https://meta.mathoverflow.net/a/5014/2362&quot;&gt;here&lt;/a&gt;. Given these difficulties, the challenge of communicating all of (1),(2), and (3) in a single &lt;em&gt;name&lt;/em&gt; seems beyond the reach of current methods.&lt;/p&gt;&#xA;&lt;p&gt;So if we were to try to deter off-topic questions by changing the name, the only avenue I could imagine at this point would be to choose some very clinical and stuffy-sounding name which would be indecipherable to most people on the internet, so that they would not suspect we're talking about mathematics here. I, and I think many others here, would be very unhappy with such an approach for many reasons. Among them would be sentimental value of the current and historical name, as well as worries about attracting users whom we &lt;em&gt;do&lt;/em&gt; want to attract.&lt;/p&gt;&#xA;&lt;p&gt;For these reasons, the name MathOverflow is not going anywhere.

If you need further clarification or convincing that this premise is in fact flawed, you can ask for such in the comments.&lt;/p&gt;&#xA;&lt;p&gt;On a larger scale, one should be careful when asking a question on MO of the form &amp;quot;I think there's a deficiency in the following paper&amp;quot;.

After all, if you are &lt;em&gt;sure&lt;/em&gt; there is a deficiency, then MO is probably not the place to air it out -- much better to contact the author directly. (Side note: it is an unfortunate reality that sometimes errata are not published even when the author agrees there is a deficiency in their paper. However, that doesn't mean it's appropriate to ask a MO &amp;quot;question&amp;quot; simply to publicize such a deficiency.) On the other hand, if you're &lt;em&gt;not&lt;/em&gt; sure there is a deficiency, a question suggesting that there is a deficiency always runs a definite risk of getting egg on your face if it turns out you just misunderstood. Even if it turns out your hunch is correct and there &lt;em&gt;is&lt;/em&gt; a deficiency, your &amp;quot;question&amp;quot; might come across as a bit rude.&lt;/p&gt;&#xA;&lt;p&gt;On the other hand, phrasing a question as &amp;quot;I don't understand the following part of the following paper&amp;quot; not only hedges against the possibility that you really just don't understand, but also has all the same benefits.

I understand the philosophy that we gain extra exposure by bountying a question and that an answer isn't what we 'buy' with the bounty necessarily, but I think this should be made more explicit in the blurb we see when offering a bounty.&lt;/p&gt;&#xA;&lt;p&gt;I also think there might be some merit to (partially? 50%?) refunding bounties on questions posted by different users than the bounty placer, on the grounds that this still prevents endless promotion of ones own content while encouraging us to support one another (without punishment) in asking good questions.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;To respond to Martin and Gerry's comments, I am primarily taking issue with the change of phrasing implemented back in 2013:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/Cq5Kp.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/Cq5Kp.png&quot; alt=&quot;&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;The way it is written reads to me as &amp;quot;this reputation is deducted immediately and cannot be refunded &lt;em&gt;if you change your mind&lt;/em&gt;&amp;quot;, or in other words you can't revoke it during the 7 day period for any reason. This might just be my denseness in reading, but I think less ambiguous language would be better.

It makes sense to migrate if a question is &lt;i&gt;better suited&lt;/i&gt; to MSE; it doesn't necessarily make sense to migrate just because the question &lt;i&gt;can be answered&lt;/i&gt; on MSE.  In what follows, let me pretend that the wording &amp;quot;can be answered&amp;quot; has been changed to &amp;quot;better suited&amp;quot; since that may have been what was intended anyway.&lt;/p&gt;&#xA;&lt;p&gt;Suppose that a question that is better suited to MSE gets asked on MO and is well-received.  Does that mean it shouldn't be migrated?  I'm not sure.  Whether the question is well-received is an &lt;i&gt;a posteriori&lt;/i&gt; criterion and I think that in general, we should be using &lt;i&gt;a priori&lt;/i&gt; criteria to judge which site is more appropriate.  Otherwise it tempts people to try to &amp;quot;game the system&amp;quot; and try their luck posting to a site that they kind of know is the wrong site.&lt;/p&gt;&#xA;&lt;p&gt;For the particular question under discussion, I think the point is that it's not clear that MSE is actually the better site.  The question does have some flaws; as &lt;a href=&quot;https://meta.mathoverflow.net/questions/5088/rationale-for-migration-to-mse-of-a-well-received-question-on-mo/5092?noredirect=1#comment26156_5088&quot;&gt;someone has pointed out&lt;/a&gt;, the asker should probably have done some Googling first, but these flaws just mean that the question should be improved (regardless of which site it is posted to), and don't really address the issue of which site is better.  &lt;a href=&quot;https://math.stackexchange.com/questions/4188429/novel-proof-of-the-irrationality-of-sqrt3#comment8684720_4188429&quot;&gt;Andrés E. Caicedo's comment&lt;/a&gt; indicates that &lt;i&gt;some version of the question&lt;/i&gt; could have been better suited to MO, but I'm not sure that the &lt;i&gt;question as asked&lt;/i&gt; is better suited to MO.&lt;/p&gt;&#xA;&lt;p&gt;I agree that migration can be disruptive and annoying.  So I'd propose the following policy: if there is doubt about whether MO or MSE is more suitable, then leave it on MO; but if it's fairly clear that MSE is more suitable, then go ahead and migrate it even if the question is &amp;quot;well-received.&amp;quot;  (Of course, if the question has flaws, then those should be addressed, probably before any decision about migration is made.)&lt;/p&gt;&#xA;" OwnerUserId="3106" LastEditorUserId="3106" LastEditDate="2021-07-07T20:14:12.893" LastActivityDate="2021-07-07T20:14:12.893" CommentCount="7" ContentLicense="CC BY-SA 4.0" />

Living in a 3rd word country ( I will add full details if I am allowed to ask on MO) : I completed my masters in math in Jun 2020. Then I wanted to study some additional topics before applying in Europe. So, took 1 year break and went home. studied fine till Jan 2021 , then verbal abuse stated by my father and occasionally by my mother( They earlier also used to verbal  abuse me but I didn't did my bachelors and masters in my native city, so less impact was on me). Admitted to mental hospital for a 10 days in Feb and misdiagnosed with skiezoprenia( I have depression). Verbal and emotional abuse continues and again admitted to different hospital in march end for 11 days, diagnosed for depression. Verbal abuse again continues after some days of discharge. So, I move out taking a part time job to sustain myself in different city on 1 July and learning some new math topics alongside. Thinking about suicide since March 2021 but postponed to try 1 more year if I am not able to get a phd position as learning and doing math is the only thing I like. ( Reason of verbal abuse:  Parents wanted me to do full time job and not math research so that I can settle early and also wanted me to take a career like medical doctor or engineer which is more earning and takes less time to settle time). I could only study 1 month of math in these 6 months.&lt;/p&gt;&#xA;&lt;p&gt;Question which I am about to post on MO : How much should I mention the situation due to my 6 months are being wasted in my CV when applying to PHD position in Mathematics ?

MO wants to intimidate graduate students into thinking their questions are too trivial by deeming them offtopic.&lt;/p&gt;&#xA;&lt;p&gt;For all the inanity and Red Guards posturing of math graduate students (and even faculty) on Twitter, this is nonetheless a real problem that they've highlighted about MO's unfriendliness.&lt;/p&gt;&#xA;" OwnerUserId="169482" LastEditorUserId="169482" LastEditDate="2021-08-17T02:26:22.253" LastActivityDate="2021-08-20T22:41:21.057" Title="Why was my probability question closed?"

A lot of posted questions are reasonable but unclear or otherwise flawed. One approach to these questions is to vote to close, citing the flaw, ask the poster to fix the flaw, and thus reopen. The second approach is to ask the poster to fix the flaw first, and only close later if they refuse to do so. I think the first is very unwelcoming but the second is necessary.&lt;/p&gt;&#xA;&lt;p&gt;I don't fully understand the timeline in your case but it looks closer to the second. In particular, Anthony Quas gave a comment pointing out what needed to be clarified, and the question wasn't deleted until days later (after, according to other comments, you deleted and then undeleted it instead of changing anything).&lt;/p&gt;&#xA;&lt;p&gt;The second is about presentation. Your question was presented in word problem format, without an associated purely mathematical formulation. This led to confusion as the word problem was ambiguous, but it also led people to mistrust your question as what a math researcher, absolutely including a grad student, would typically do is give formulas in addition to (or instead of) the word-problem motivation.

There are c.600 affected questions and it looks like a large proportion of the links could be fixed by a simple search-and-replace; so comments and &lt;a href=&quot;https://meta.mathoverflow.net/a/4517/2273&quot;&gt;the well-received answer&lt;/a&gt; suggested asking SE employees to do such a search-and-replace fix (moderators don’t have that ability), but felt “down for a few weeks” was too soon.&lt;/p&gt;&#xA;&lt;p&gt;The frontend has now been down for 17 months; presumably this is no longer too soon.  &lt;strong&gt;Can moderators now petition SE for a search-and-replace fix?  Or if that’s too administratively difficult, should we just fix the links by hand, trying not to bump too many at once as usual?&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Useful search queries, copied from the older question:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://mathoverflow.net/search?q=url%3a%22*front.math.ucdavis.edu*%22&quot;&gt;posts containing url:&amp;quot;*front.math.ucdavis.edu*&amp;quot;&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://mathoverflow.net/search?tab=active&amp;amp;q=url%3a%22*front.math.ucdavis.edu*%22&quot;&gt;posts containing it that have recently been bumped&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Search-and-replace suggestion: The links fall into several groups, some that should be easy to recognise and fix by regex, others less clear.  Hopefully a large proportion can be fixed by regex, leaving the rest to fix by hand.&lt;/p&gt;&#xA;&lt;p&gt;For links to preprints &lt;a href=&quot;https://arxiv.org/help/arxiv_identifier&quot; rel=&quot;nofollow noreferrer&quot;&gt;after April 2007&lt;/a&gt;, the correspondence is straightforward — we want to replace a url like &lt;code&gt;http://front.math.ucdavis.edu/0809.1179&lt;/code&gt; with &lt;code&gt;https://arxiv.org/abs/0809.1179&lt;/code&gt;, and the first four digits represent &lt;code&gt;YYMM&lt;/code&gt;.  So a regex replacing &lt;code&gt;https?://front.math.ucdavis.edu/([12]|0[8-9]|071|070[4-9])&lt;/code&gt; with &lt;code&gt;https://arxiv.org/abs/\1&lt;/code&gt; should recognise and fix these links, I think.  (Details depend on the regex flavour used, of course.)&lt;/p&gt;&#xA;&lt;p&gt;Links to older preprints are less consistent.  Some have the form &lt;code&gt;https://front.math.ucdavis.edu/math.LO/9909115&lt;/code&gt;, and these should be easy again: the identifier part agrees with the arXiv’s, so a regex replace of &lt;code&gt;https?://front.math.ucdavis.edu/(math[.a-zA-Z]*/\d+)&lt;/code&gt; by &lt;code&gt;https://arxiv.org/abs/\1&lt;/code&gt; should recognised and fix these.  But others use a different identifier, whose correspondence with the arXiv’s identifiers seems unclear — e.g. &lt;code&gt;http://front.math.ucdavis.edu/0310.5109&lt;/code&gt; corresponds to &lt;code&gt;https://arxiv.org/abs/math/0310109&lt;/code&gt; (and &lt;code&gt;https://arxiv.org/abs/0310.5109&lt;/code&gt; doesn’t work).

I really do think it's important that the links on this site are functional, so I appreciate your bringing this up for discussion.&lt;/p&gt;&#xA;&lt;p&gt;The tool we have to make this change is a pretty simple find/replace tool that only works for post content, not comments. It only works for URLs and it can't accept RegEx. So, I think you may already see the problem. While I really appreciate the effort that y'all went to to find the various treatments of the URLs, we can't even only update the ones that are an easy swap without changing all of the others since the content needing to be replaced is the same in all cases.&lt;/p&gt;&#xA;&lt;p&gt;As you might also see, this doesn't mean that we can't ever do this - it means that we'd need you to help us out before we can. Based on the comments, it sounds like about 2/3 of the ~900 links are the &amp;quot;easy&amp;quot; first and second type. If that's the case, you could manually repair the remaining ~300 URLs first and we can use the link editing tool to fix the remainder of the links which, despite being in two formats require the same change to happen since arXiv helpfully automatically redirects to the correct URL.&lt;/p&gt;&#xA;&lt;p&gt;So to put it in other words:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;First you all work together to fix the outstanding links of the second and third type manually.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Based on a &lt;a href=&quot;https://meta.mathoverflow.net/questions/5124/is-it-time-to-replace-links-to-the-ucdavis-arxiv-frontend#comment26339_5124&quot;&gt;comment from Martin Sleziak&lt;/a&gt; it looks like there's about 300 links in the third category. It seems like correcting these links in an automated way may be difficult regardless since it's unclear how they should change.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Once the difficult URLs are fixed, we will bulk find/replace the remaining using the following method:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Find &lt;code&gt;http://front.math.ucdavis.edu/&lt;/code&gt; and replace with &lt;code&gt;https://arxiv.org/abs/&lt;/code&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;As far as I understand, we can not bulk edit all 900 URLs first as it will make the pre-2007 URLs even more &amp;quot;wrong&amp;quot; and may make them more difficult to find and repair at a later point in time.&lt;/p&gt;&#xA;&lt;p&gt;If you can find a consistent way to convert from one of the pre-2007 URLs to the new arXiv URL, you may be able to have someone create a userscript to update these over time, a few questions per day but that's a big &amp;quot;if&amp;quot;.&lt;/p&gt;&#xA;&lt;p&gt;Please let me know if this is clear or if you have any other questions about this response.&lt;/p&gt;&#xA;" OwnerUserId="122216" LastActivityDate="2021-09-10T17:11:11.500" CommentCount="12" ContentLicense="CC BY-SA 4.0" />

For example, you can set on of them, &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1470017/deleted-accounts-above-the-given-score-and-number-of-posts?minscore=0&amp;amp;minposts=0&quot; rel=&quot;nofollow noreferrer&quot;&gt;or even both, to zero&lt;/a&gt; - to remove the restriction. (As you have already mentioned, once you have userid, you can find more about that user, such as the list of their posts: &lt;a href=&quot;https://meta.mathoverflow.net/q/3748&quot;&gt;Is there a way to check all questions/answers posted from a deleted account&lt;/a&gt;. I will add that sometimes you might be able to find also a username that the user had before the deletion - the methods mentioned here work also for deleted users: &lt;a href=&quot;https://meta.mathoverflow.net/q/4426&quot;&gt;Recognizing identifiable users changing user names&lt;/a&gt;.)&lt;/p&gt;&#xA;&lt;p&gt;You can make a similar query which lists both existing and deleted users: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1470018/users-above-the-given-score-and-number-of-posts?minscore=500&amp;amp;minposts=50&quot; rel=&quot;nofollow noreferrer&quot;&gt;Users above the given score and number of posts&lt;/a&gt;. Of course, if we're making a query combining both deleted and existing users, we can include also some data from the table Users for the ones which are not deleted, like &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1470030/users-above-the-given-score-and-number-of-posts&quot; rel=&quot;nofollow noreferrer&quot;&gt;in this query&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;I can also imagine, that somebody might be interested in finding active users in some specific area rather than on MO in general. This query might possibly help with that: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1470034/deleted-accounts-above-the-given-score-and-number-of-posts-in-a-specific-tag&quot; rel=&quot;nofollow noreferrer&quot;&gt;Deleted accounts above the given score and number of posts in a specific tag&lt;/a&gt;.

I will also add that if you have a post or a comment from a deleted user, you can see the userid there. You will find &lt;code&gt;userxyz&lt;/code&gt; - where &lt;code&gt;xyz&lt;/code&gt; is the userid - in places where you see username for the accounts which are not deleted.&lt;/p&gt;&#xA;&lt;p&gt;If you remember the username and you want the userid, you might simply try to search &lt;a href=&quot;https://www.google.com/search?q=quid+site:mathoverflow.net&quot; rel=&quot;nofollow noreferrer&quot;&gt;where the username was mentioned on MO&lt;/a&gt; - which might lead you to some of their posts or comments. Or you can search for &lt;a href=&quot;https://meta.mathoverflow.net/q/3247&quot;&gt;comments mentioning this username&lt;/a&gt; - and you might be lucky enough that you'll find a comment responding to a comment from the delete user. Examples of such queries are &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/556789/comments-containing-given-keyword-with-text-and-author?Word=quid&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/556789/comments-containing-given-keyword-with-text-and-author?Word=@quid&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;Reputation is present in the Users table - but the users who were deleted are no longer present there. Even for users who aren't deleted, it is rather difficult to use the other data to get something which matches the reputation. Some discussions related to calculating reputation from SEDE: &lt;a href=&quot;https://meta.stackexchange.com/q/300600&quot;&gt;How to retrieve exact reputation on &amp;quot;legendary day&amp;quot;?&lt;/a&gt;, &lt;a href=&quot;https://meta.stackexchange.com/q/144716&quot;&gt;Reputation History from Data Explorer&lt;/a&gt;, &lt;a href=&quot;https://meta.stackexchange.com/q/234720&quot;&gt;A query, days hitting rep cap vs days a member (rep)&lt;/a&gt;, &lt;a href=&quot;https://meta.stackexchange.com/q/313561&quot;&gt;Determining user's reputation as of particular date?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;Maybe you noticed the apparent discrepancy that for some of the users the column &amp;quot;Posts&amp;quot; shows a bigger number than the number of answers and questions together. The reason is that the table Posts in the database also includes the tag-wikis that the user created.

But that search won't show you the deleted questions.&lt;/li&gt;&#xA;&lt;li&gt;10k+ users can &lt;a href=&quot;https://mathoverflow.net/search?q=%5Bgroupoids%5D+%5Bfoliations%5D+deleted%3A1&quot;&gt;add the search modifier deleted:1&lt;/a&gt; to any search and in that way they can search among &lt;em&gt;their own&lt;/em&gt; deleted posts. But this doesn't work for users below 10k. See also: &lt;a href=&quot;https://meta.mathoverflow.net/q/3254&quot;&gt;Can I somewhere see my own deleted questions?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;Maybe it is reasonable to save regularly all your posts and or at least links to all your posts.

See also: &lt;a href=&quot;https://meta.mathoverflow.net/q/5003&quot;&gt;How to make sure your questions never disappear in a blackhole?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;Or if you do not want the hassle of saving all of your content, you can at least check from time to time whether some of your posts are in danger of being deleted by &lt;a href=&quot;https://mathoverflow.net/help/roomba&quot;&gt;roomba&lt;/a&gt;. For example, by checking your questions which have score 0 and no answers, i.e. searching for &lt;a href=&quot;https://mathoverflow.net/search?q=user%3Ame+is%3Aq+answers%3A0+score%3A..0&quot;&gt;user:me answers:0 score:..0&lt;/a&gt;.

At first glance, this question seems to be of the genre, &amp;quot;Is this paper about a famous problem correct?&amp;quot; which the MO community has long ago decided is off-topic unless specific technical issues are spelled out in the MO question.  However, this question is slightly different. It is not directly asking about Perelman's paper; it is asking about &lt;i&gt;a statement published by Shing-Tung Yau&lt;/i&gt;, raising doubts about whether Perelman's argument has been fully checked.&lt;/p&gt;&#xA;&lt;p&gt;Complicating the matter is that Yau's comments are, by his own admission, phrased in a controversial (&amp;quot;subjective and argumentative&amp;quot;?) manner.  That initially influenced me to agree with those who voted to close (although I myself did not vote to close).  However, the &lt;i&gt;MO question itself&lt;/i&gt; does not strike me as subjective and argumentative.  The MO question seems more in line with questions such as &lt;a href=&quot;https://mathoverflow.net/q/351640&quot;&gt;Extent of “unscientific”, and of wrong, papers in research mathematics&lt;/a&gt;, which asks about whether published and &amp;quot;generally accepted&amp;quot; papers are really as rock-solid as the mathematics community would like to believe.  In a &lt;a href=&quot;https://mathoverflow.net/questions/407914/has-perelmans-proof-been-accepted-or-are-there-still-unresolved-issues?noredirect=1#comment1048168_407914&quot;&gt;comment&lt;/a&gt;, arsmath wrote:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;I'm not trying to defend Yau, since the consensus is that he's wrong. I am trying to defend the principle that asking the question is legitimate. I don't see any way to interpret what happened here other than we as a community have decided to cover up any embarrassing fights. Which, to my mind, is more embarrassing than the fight itself.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I think that arsmath has a valid point.  Note that an earlier &lt;a href=&quot;https://mathoverflow.net/questions/407914/has-perelmans-proof-been-accepted-or-are-there-still-unresolved-issues?noredirect=1#comment1046106_407914&quot;&gt;comment by GH from MO&lt;/a&gt;, affirming the legitimacy of the MO question, has been upvoted 10 times as of this writing.  Even before arsmath's comment, I had cast the third vote to reopen the question.  Those reopen votes seem to have expired, and since the question isn't currently active, the only realistic path to reopening seems to be a post here on meta.&lt;/p&gt;&#xA;&lt;p&gt;If the question were reopened, I would try to answer it by saying that the correctness of a paper, especially one containing a very complicated argument, is not a simple binary question, but lies on a continuum.  It is not unreasonable to draw attention to a published argument and suggest that it should be scrutinized by more people, digested properly by the community, and generalized or adapted to other problems if possible.  The trouble is that Yau has gone about this in an intentionally tactless manner, making Perelman's work seem more doubtful than it is, and courting controversy while disingenuously claiming to care only about the math.  In my answer, which I would make community wiki, I would also reproduce the mathematical content of some of the comments, which cite recent work that builds on Perelman's ideas.&lt;/p&gt;&#xA;" OwnerUserId="3106" LastEditorUserId="4177" LastEditDate="2021-11-18T03:41:24.277" LastActivityDate="2021-11-18T03:41:24.277" CommentCount="11" CommunityOwnedDate="2021-11-16T23:30:54.453" ContentLicense="CC BY-SA 4.0" />

However, I would accept that this is a matter of judgement.&lt;/li&gt;&#xA;&lt;li&gt;OP was very offended by the comment about MSE.  They stated (in a now deleted comment) that they are a tenured academic giving graduate level lectures on differential geometry, and that it was rude to suggest that their question should be migrated to a &amp;quot;site for helping undergraduates to cheat&amp;quot;.  They reiterated this view of MSE in another comment that has also been deleted (apparently by a moderator).&lt;/li&gt;&#xA;&lt;li&gt;I think that most of us would agree that OP's opinion of MSE is inaccurate, and disparaging to many MSE users who we respect (including many people who are active on both MO and MSE).  However, it is not hard to imagine how someone might form that opinion; ideally it would be corrected by exposure to more information.&lt;/li&gt;&#xA;&lt;li&gt;While OP's feeling of offense is clearly enhanced by their low opinion of MSE, I think that it is natural to be somewhat upset at the suggestion that a clear, well-posed, graduate level question needs to be migrated.  If people feel a need to make such a suggestion, I would hope that they could do so respectfully and with more explanation.&lt;/li&gt;&#xA;&lt;li&gt;So OP got an answer to their question, but it seems that they did not enjoy the experience, and are unlikely to return.

But pretty much everyone at a graduate level and above is offended when their question is criticized as not research-level, and frequently very offended. This is one of the biggest things that leads people to have a negative experience on MO and leave the site. Thus it is best to avoid saying this except in really extreme cases.&lt;/p&gt;&#xA;&lt;p&gt;If someone is hurt or offended by an initial comment, and makes this clear, it's better to acknowledge and apologize for this in follow-up comments. If A says something rude to B and B responds by saying something rude to A, then C shouldn't show up and correct only B's rudeness, even in a perfectly polite way. Better to apologize on behalf of A and then correct B's rudeness, or say something nice and give people time to cool down. (One user, Somatic Custard, had good intent here but probably could have phrased it better.)&lt;/p&gt;&#xA;&lt;p&gt;One way to prevent situations like this is to think about the opinions of others on the site before criticizing. If you think a question is bad but it is reasonably well upvoted, or similar questions have been upvoted in the past, then you disagree with other MO users on what is an acceptable question. If the question gets significantly more upvotes than a critical comment, then you are likely in the minority.

From the fact that this comment wasn't deleted by moderators I understand that the moderators also didn't believe it qualifies as rude. On the other hand, I found the tone of the OP in the comments excessive (and also peremptory, notably about the scope of MSE), and I'm a bit worried (also as a regular user of MSE) that these comments got so many upvotes.&lt;/p&gt;&#xA;&lt;p&gt;By the way, and as an analogy, as a referee one often has to recommend rejection of a paper in research journals; as an author one often has to undergo such rejections: one should not view this as exchange of insults, even if the negative assessment turns out to be unfair. Of course here standards are different, but it's the same principle: one has to accept criticism. And here, more than in a journal process, one has room to reply to criticism.&lt;/p&gt;&#xA;&lt;p&gt;P.S.

What's missing, and what new information you're trying to gain from this effort in duplication.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Do not be disappointed if users still feel that this was a misguided idea, downvote, close, or delete your question.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;Good luck.&lt;/p&gt;&#xA;" OwnerUserId="7206" LastActivityDate="2022-01-11T14:39:37.373" CommentCount="2" ContentLicense="CC BY-SA 4.0" />

(You can also &lt;a href=&quot;https://data.stackexchange.com/meta.mathoverflow/query/919952/socratic-badge-progress?userid=398&quot; rel=&quot;nofollow noreferrer&quot;&gt;choose MathOverflow Meta&lt;/a&gt; and various other sites.)&lt;/li&gt;&#xA;&lt;li&gt;The query has a parameter userid — where you have to enter your userid.&lt;/li&gt;&#xA;&lt;li&gt;You should also keep in mind that the data in this database are only updated once a week.&lt;/li&gt;&#xA;&lt;li&gt;As a side note, it is slightly better to be logged in on SEDE. (So that you do not have to solve a captcha when running a query.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;The userid is the number you can see in the URL and in the  search bar when you go to your profile page. (If you have accounts on several sites, userid on each of them will be different.) More details on this: &lt;a href=&quot;https://meta.stackexchange.com/q/98771&quot;&gt;What is my user ID?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;Regarding the original question about badge progress towards the next Socratic badge, it might be useful to add some links.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;There is the following feature request on Meta Stack Exchange: &lt;a href=&quot;https://meta.stackexchange.com/q/271984&quot;&gt;Track next Socratic badge progress&lt;/a&gt;. In fact, &lt;a href=&quot;https://meta.stackexchange.com/questions/271984/track-next-socratic-badge-progress/317719#317719&quot;&gt;Glorfindel's answer&lt;/a&gt; to that question contains precisely the query mentioned above. (And it also mentions the warning that the query will not be precise.)&lt;/li&gt;&#xA;&lt;li&gt;There is also this post on Meta Stack Overflow: &lt;a href=&quot;https://meta.stackoverflow.com/q/318148&quot;&gt;I would like to track my next Socratic badge&lt;/a&gt;. And one more related post on Meta Stack Exchange: &lt;a href=&quot;https://meta.stackexchange.com/q/328778&quot;&gt;How can we see our progress towards the next Socratic badge?&lt;/a&gt; In both cases, another SEDE query was suggested: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/229495/progress-towards-curious-inquisitive-and-socratic-badges?userid=398&quot; rel=&quot;nofollow noreferrer&quot;&gt;Progress towards Curious, Inquisitive and Socratic badges&lt;/a&gt;. (This one was created by Jon Ericson. Unlike Glorfindel's query, this one only counts the number of days — it does not check whether a user has a positive question record, which is the other requirement for this badge.) In this specific case, this query returns one more day than the other one (at the moment). The query contains a comment saying: &amp;quot;only posts closed within 60 days count against qualification&amp;quot;. This might be a possible explanation for the difference (which could be caused by &lt;a href=&quot;https://mathoverflow.net/posts/29485/revisions&quot;&gt;Work of ICM 2010 plenary speakers (and other humans)&lt;/a&gt;).&lt;/li&gt;&#xA;&lt;li&gt;In case you want to examine more closely which days actually contribute to those numbers, here is &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1542142/question-record-per-day?userid=398&quot; rel=&quot;nofollow noreferrer&quot;&gt;a query looking at individual days&lt;/a&gt;. It basically contains just one small part of the query linked above. (For example, if you sort the results by the number of questions, you can see the days when you asked more than one question.) You can find questions from a specific date using search with the parameters &lt;a href=&quot;https://mathoverflow.net/search?q=user%3Ame+is%3Aq+created%3A2011-04-26&quot;&gt;user:me is:q created:YYYY-MM-DD&lt;/a&gt;. 10k+ users can also search among their deleted posts &lt;a href=&quot;https://mathoverflow.net/search?q=user%3Ame+is%3Aq+created%3A2011-04-26+deleted%3A1&quot;&gt;by adding deleted:1&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Those SEDE queries take into account only the questions which are not deleted. If you also want to review your deleted questions, here is a post saying how to find them: &lt;a href=&quot;https://meta.mathoverflow.net/q/3254&quot;&gt;Can I somewhere see my own deleted questions?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;I took the query created by Jon Ericson and modified it to a version which returns these numbers for more users, not just one. You can see here the result on the &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1542318&quot; rel=&quot;nofollow noreferrer&quot;&gt;main site&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/meta.mathoverflow/query/1542318&quot; rel=&quot;nofollow noreferrer&quot;&gt;on meta&lt;/a&gt;.

Users with reputation 1 stand out among other posts, which makes noticing possible spam questions/answers in the list of recently active questions a bit easier. (A discussion on how MO manages to cope with spam might deserve a separate question. To include at least some stats, here are SEDE queries showing how fast spam posts were removed on the &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1473119/time-until-spam-posts-were-deleted&quot; rel=&quot;nofollow noreferrer&quot;&gt;main&lt;/a&gt; site and on &lt;a href=&quot;https://data.stackexchange.com/meta.mathoverflow/query/1473119/time-until-spam-posts-were-deleted&quot; rel=&quot;nofollow noreferrer&quot;&gt;meta&lt;/a&gt;.

Newbies often post questions which can have some problems. They might be off-topic questions, in such cases the question needs to be closed and maybe some advice to the OP in the comment might be useful. Even if the question is on-topic, it's possible that the new user might need some help - to mention some common situations as examples, the user might be unfamiliar with Markdown and MathJax, with the tags used on MO or with the guidelines related to cross-posting.

For example, in the screenshot below, note that in the upper left, &lt;span class=&quot;math-container&quot;&gt;$y^3 = x^4 + x+1$&lt;/span&gt; renders fine, but elsewhere the raw &lt;span class=&quot;math-container&quot;&gt;$\rm\TeX$&lt;/span&gt; is displayed.

But perhaps a summary in one place might be useful.

(The title and the body of the question was edited a few times since I posted this answer. Looking at the version &lt;a href=&quot;https://meta.mathoverflow.net/revisions/5262/2&quot;&gt;at the time when I posted this&lt;/a&gt;, it seemed to me that the main focus of the question was whether some kind of mass-edits without bumping are possible.)&lt;/p&gt;&#xA;&lt;p&gt;It seems that the main question is whether it is possible to make edits to posts without &lt;a href=&quot;https://meta.mathoverflow.net/tags/bumping/info&quot;&gt;bumping&lt;/a&gt; those questions to the frontpage. And there are two aspects to it:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Is there some possibility to make non-bumping edits manually?&lt;/li&gt;&#xA;&lt;li&gt;Is there a possibility to make mass edits without bumping in batches?&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;strong&gt;Manual edits&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Several times in the past it was suggested that there should be an option to make some minor edit in a way which doesn't bump the question.&lt;/p&gt;&#xA;&lt;p&gt;It is clear that there are some problems connected with this idea — for example, vandalism or inserting spam links into an old post are more likely to get noticed when the post is bumped. Without bumping, also well-intentioned but incorrect edits could easily fly under the radar. One possible solution to such issues could be that such edits would go through a review queue (similarly as suggested edits). So at least somebody would check whether the edit is correct.&lt;/p&gt;&#xA;&lt;p&gt;It is difficult to guess whether at some point in future Stack Exchange might decide to implement this. But this feature is not available now.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://meta.mathoverflow.net/q/192&quot;&gt;Minor edits, subject to review&lt;/a&gt; on MathOverflow Meta, repeated also here: &lt;a href=&quot;https://meta.mathoverflow.net/q/1053#1092&quot;&gt;Big list of feature requests and suggestions for a fantasy MO 3.0&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://meta.stackexchange.com/q/122567&quot;&gt;Allow non-bumping minor edits, but review them on /review&lt;/a&gt; on Meta Stack Exchange&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;strong&gt;Mass edits&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;The &lt;a href=&quot;https://meta.stackexchange.com/tags/community-managers/info&quot;&gt;community managers&lt;/a&gt; have a tool which can do some mass edits without bumping any posts. This tool has some limitations — it can only do simple replacement of one specific string by another, nothing more complex.&lt;sup&gt;1&lt;/sup&gt;&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;This tool was used in the network-wide HTTP to HTTPS conversion — that was an event which hardly could go unnoticed by any active MO/SE user.&lt;sup&gt;2&lt;/sup&gt;&lt;/li&gt;&#xA;&lt;li&gt;There are also some cases when this was used to correct links to some domain — after some website moved or changed its structure.&lt;sup&gt;3&lt;/sup&gt; In fact, something similar was relatively recently discussed also on this meta — although at the moment this wasn't done.&lt;sup&gt;4&lt;/sup&gt;&lt;/li&gt;&#xA;&lt;li&gt;However, I haven't seen this tool being used to correct &lt;strong&gt;misspellings&lt;/strong&gt;. (Maybe somebody knows about such instance and they will correct me.) As already mentioned, one of the current moderators suggested something along these lines in the &lt;a href=&quot;https://meta.mathoverflow.net/questions/3952/misspelling-of-cauchy-schwarz#comment17493_3952&quot;&gt;comments&lt;/a&gt; to this older discussion: &lt;a href=&quot;https://meta.mathoverflow.net/q/3952&quot;&gt;Misspelling of Cauchy-Schwarz&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;Stack Exchange CMs typically do such mass-replacements only if there is a lot of posts which are influenced. If there aren't that many posts, it is preferred that they are edited manually. (The boundary seems to be &lt;a href=&quot;https://chat.stackexchange.com/transcript/message/59114567#59114567&quot;&gt;somewhere around 100 posts&lt;/a&gt;.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;strong&gt;Scripts and bots&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;In this context, it is worth mentioning that sometimes edits which can be automated are done using scripts run by some users rather than by Stack Exchange. This still bumps the questions — but since it is automated, the edits can be reasonably spaced. I am aware of such edits done by Glorfindel. There is also a related discussion on this meta: &lt;a href=&quot;https://meta.mathoverflow.net/q/4057&quot;&gt;Are edits performed by external, non-SE robots allowed?&lt;/a&gt; Recently there were some edits of &lt;a href=&quot;https://meta.mathoverflow.net/q/5124#5223&quot;&gt;arXiv front-end links&lt;/a&gt; and &lt;a href=&quot;https://math.meta.stackexchange.com/q/34479#34482&quot;&gt;PlanetMath links&lt;/a&gt;. (Of course, it is possible that other users do similar things — I have mentioned the user I am aware of. And who knows — maybe some users managed to automate also answering questions…?)&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;To quote from &lt;a href=&quot;https://en.wikipedia.org/wiki/Yes_Minister&quot; rel=&quot;nofollow noreferrer&quot;&gt;Yes Minister&lt;/a&gt;:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Hacker: So, on balance, it is a good idea?&lt;br /&gt;&#xA;Sir Humphrey: On balance... yes and no.&lt;br /&gt;&#xA;Hacker: That's not a very clear answer.&lt;br /&gt;&#xA;Sir Humphrey: It's a balanced answer.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;So one could half-jokingly say that the answer to your question asking whether some users &amp;quot;have the power to make some batch replacement … without disturbing the front page&amp;quot; is both yes and no.&lt;/p&gt;&#xA;&lt;p&gt;Only the CMs can actually run such mass replacements. But any user can &lt;em&gt;propose&lt;/em&gt; such thing here on meta — naturally, there is no guarantee that it will actually  be implemented. (Of course, the mods are in somewhat better position than regular users — they often communicate with the CMs, there is even &lt;a href=&quot;https://meta.stackexchange.com/tags/teachers-lounge/info&quot;&gt;a private chatroom&lt;/a&gt; for the diamond-bearing users. So it is easier for the mods to discuss things like this with the CMs.)&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;Some information on this tool can be found, for example, here: &lt;a href=&quot;https://meta.stackexchange.com/q/313243&quot;&gt;How to find and/or change a set of hyperlinks on a site?&lt;/a&gt; and &lt;a href=&quot;https://meta.stackexchange.com/q/375121&quot;&gt;Can the mass-replacement tool also replace and remove?&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;See also: &lt;a href=&quot;https://meta.stackexchange.com/q/292058&quot;&gt;Network-wide HTTPS: It's time&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;3&lt;/sup&gt;Some instances I am aware of/I was able to find: &lt;a href=&quot;https://hinduism.meta.stackexchange.com/q/1969&quot;&gt;Is it possible to mass-update broken URLs to IndianScriptures.com with HinduScriptures.in?&lt;/a&gt; on Hinduism, &lt;a href=&quot;https://scifi.meta.stackexchange.com/q/9922&quot;&gt;Chakoteya.net links are broken&lt;/a&gt; on Science Fiction &amp;amp; Fantasy, &lt;a href=&quot;https://scifi.meta.stackexchange.com/q/12715&quot;&gt;Can we fix broken Memory Alpha links?&lt;/a&gt; on Science Fiction &amp;amp; Fantasy, &lt;a href=&quot;https://boardgames.meta.stackexchange.com/q/2068&quot;&gt;Mass-fix broken links from old usages of autocard functionality&lt;/a&gt; on Board &amp;amp; Card Games, &lt;a href=&quot;https://judaism.meta.stackexchange.com/q/4599&quot;&gt;chabadlibrary.org link structure has changed, and there are now many broken links&lt;/a&gt; on Mi Yodeya.

Quite a lot of those links have been already edited — you can find some stats in the answers to the linked question and also in &lt;a href=&quot;https://chat.stackexchange.com/transcript/message/60311544#60311544&quot;&gt;MO editors' lounge&lt;/a&gt;.

(I have chosen the startpoint in November - so that it is easier to compare the graphs with the ones that have already been posted.)&lt;/p&gt;&#xA;&lt;p&gt;Here are some examples of queries which could (very roughly) correspond to some measure of activity on a Stack Exchange site.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1566594/number-of-posts-per-week-between-two-dates-including-the-deleted-posts?Date1=2021-11-07&amp;amp;Date2=2022-04-30#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;Number of posts/questions/answers per week - including the deleted posts&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;If you'd prefer grouping posts by month rather than by week, some of the queries I posted here could be used: &lt;a href=&quot;https://meta.mathoverflow.net/q/4505&quot;&gt;Does the number of answers really drop over years?&lt;/a&gt; For example, here are the numbers &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1566655/number-of-questions-answers-posts-per-month-including-deleted-posts#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;including the deleted posts&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1566656/number-of-questions-answers-posts-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;excluding them&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1566596/number-of-posts-per-week-between-two-dates?Date1=2021-11-07&amp;amp;Date2=2022-04-30#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;Number of posts/questions/answers per week&lt;/a&gt; (Of course, if we exclude deleted posts, the results are skewed a bit in favor of the more recent dates.)&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1566598/number-of-upvotes-downvotes-per-week-between-two-dates?Date1=2021-11-07&amp;amp;Date2=2022-04-30#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;Number of upvotes/downvotes per week between two dates&lt;/a&gt; (and similar stats &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1416686/various-types-of-votes-per-month?Date2=2023-01-01#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per month rather than per week&lt;/a&gt;)&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1566658/number-of-edits-per-week?Date1=2021-11-07&amp;amp;Date2=2022-04-30#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;Number of edits per week&lt;/a&gt; (and here are &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1230245/total-edits-per-month-without-counting-tags-title-body-separately#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;edits per month&lt;/a&gt;)&lt;/li&gt;&#xA;&lt;li&gt;Since they were mentioned in the question, let's include also &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1566662/number-of-new-users-per-week?Date1=2021-11-07&amp;amp;Date2=2022-04-30#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;number of new users per week&lt;/a&gt;.

(I have posted graphs in such way that they are cut off at the end of the week - in &lt;a href=&quot;https://meta.mathoverflow.net/revisions/5278/6&quot;&gt;the previous version&lt;/a&gt;, I included graph where the most recent datapoint counted only one day of a week - which might seem a bit misleading without an additional explanation. It would probably be good to update the pictures a few weeks later - to see how the trends change after that. &lt;strong&gt;EDIT:&lt;/strong&gt; Both graphs are now updated to show what the situation looks like at the end of April. And of course, you can run the same queries at any point in the future - do not forget to change the parameters of the queries if you want to see the results over a longer period.)&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/WFiQN.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/WFiQN.png&quot; alt=&quot;Graph after the end of April&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;We can also run a similar query &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1566601/number-of-posts-per-week-in-the-whole-network-between-two-dates-including-the?Date1=2021-11-07&amp;amp;Date2=2022-04-30#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;counting posts in the whole network&lt;/a&gt;.

(If it is likely that those links stop working at some point, all work done in converting those links would be in vain.)&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;Concerning the reliability of the link, the FAQ post linked above says: &amp;quot;All URLs on the retired platform redirect to the new platform.&amp;quot; So perhaps we could hope that links in this format should be stable.&lt;/p&gt;&#xA;&lt;p&gt;As far as the first question goes, we should keep in mind that the tool which can be used for fixing links without bumping can only replace a specific string by another string. (Some more advanced tools - such as regular expressions - aren't available at the moment. The things which are available have been discussed a bit in another &lt;a href=&quot;https://meta.mathoverflow.net/q/5124&quot;&gt;recent post on this meta&lt;/a&gt;.)&#xA;In the example above, this would mean simply removing the substring &lt;code&gt;DPubS?service=UI&amp;amp;version=1.0&amp;amp;verb=Display&amp;amp;handle=&lt;/code&gt;.

The mods can, for example, add the tag &lt;a href=&quot;/questions/tagged/featured&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;featured&amp;#39;&quot; rel=&quot;tag&quot;&gt;featured&lt;/a&gt; to some post on meta and it will appear as &amp;quot;Featured on meta.&amp;quot;&lt;sup&gt;1&lt;/sup&gt; (There is also possibility to add events - but I did not see them being used much on the Stack Exchange sites which I frequent.)&lt;/p&gt;&#xA;&lt;p&gt;So, at least in theory, if the mods would consider some FAQ post from MathOverflow Meta important enough, they would be able to keep it here almost perpetually. (By adding the &lt;a href=&quot;/questions/tagged/featured&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;featured&amp;#39;&quot; rel=&quot;tag&quot;&gt;featured&lt;/a&gt; tag once in 30 days - after it expires.) Or they could rotate some FAQ posts to keep them on the community bulletin. (At least when they do not have something else which needs the attention of the users and has to be featured.)&lt;/p&gt;&#xA;&lt;p&gt;This could be used for some FAQ posts directed mainly at the new users. But probably there is a lot of information in the FAQ posts that even regular users might have missed. (And an additional advantage would be that both the mods and the regular users would look at those FAQ posts a bit more  - and perhaps correct some outdated information given there.)&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Question:&lt;/strong&gt; Would keeping some post(s) in the community bulletin - to increase their visibility - be useful?&lt;/p&gt;&#xA;&lt;p&gt;It is worth mentioning that there were some suggestions and feature requests here on meta which were in a similar spirit. (But not specifically about the community bulletin.)&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;I will also add some counter-arguments to this suggestion - maybe some of them are more relevant, maybe less:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;It's possible that many MO users do not mind seeing some lower level questions on the main site, as long as there aren't too many of them. (And such posts are also - to some minor extent - useful.)&lt;/li&gt;&#xA;&lt;li&gt;To some extent, this is done with new users in mind. But there already is a &lt;a href=&quot;https://meta.mathoverflow.net/questions/5007/what-should-the-modal-window-for-first-time-askers-say/5073#5073&quot;&gt;modal window shown to the users before they ask their first question on MO&lt;/a&gt;. This might be considered entirely sufficient - if somebody ignores the information given here, they will probably not click on any link or banner displayed on the frontpage.&lt;/li&gt;&#xA;&lt;li&gt;Another argument might be that this is unlikely to help wit the new users - at least if we're looking at stats from other sites where somewhat similar measures were implemented, they seem rather inconclusive: &lt;a href=&quot;https://meta.serverfault.com/q/5850#5867&quot;&gt;Should folks have to click through an interstitial page to ask questions on Server Fault?&lt;/a&gt;, &lt;a href=&quot;https://math.meta.stackexchange.com/q/29630&quot;&gt;How much did &amp;quot;advice for first-time askers&amp;quot; help?&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;This would require additional work from the moderators. (And, moreover, it is possible that the MO mods do not consider something like this useful - judging from the lack of  response to the previous similar suggestions.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;Some related past discussions:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;This suggestion was posted this year: &lt;a href=&quot;https://meta.mathoverflow.net/q/5260&quot;&gt;Feature request: add short &amp;quot;about MathOverflow&amp;quot; section to the front page&lt;/a&gt;&#xA;But it did not get any response from the mods. (And if we do not count voting, there wasn't any reaction from the MO community, either.) Moreover, I am not sure whether such a modification - where a single site differs substantially from the rest of the network - can be easily done.&lt;sup&gt;3&lt;/sup&gt; My post is slightly different in that it suggests an action which can be done by the MO mods. (No intervention of Stack Exchanges developers or CMs would be needed.)&lt;/li&gt;&#xA;&lt;li&gt;This suggestion was posted in 2015: &lt;a href=&quot;https://meta.mathoverflow.net/q/2142&quot;&gt;Why is &amp;quot;what is the difference between mathoverflow and math.stackexchange?&amp;quot; not prominently displayed?&lt;/a&gt; The post is somewhat similar to this one and to the one mentioned in the previous bullet point.

As a technical point, it appears to be possible for moderators to delete a close reason or to create a new one, but not to edit the description in an existing close reason. We can also tinker with the order they appear in.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;As mentioned &lt;a href=&quot;https://meta.mathoverflow.net/a/5324/2362&quot;&gt;here&lt;/a&gt;, we've just updated the &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;help page&lt;/a&gt; to which that first, generic site-specific close reason links:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;This question does not appear to be about research mathematics within the scope defined in the &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;help center&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;We've now included language there which for the first time explicitly says that these sorts of &amp;quot;check my work&amp;quot; or &amp;quot;result announcement&amp;quot; questions are off-topic.  With these updates, the first, generic site-specific close reason &lt;em&gt;technically&lt;/em&gt; plays exactly the role suggested by Will Sawin &lt;a href=&quot;https://meta.mathoverflow.net/questions/5319/could-we-add-another-reason-for-closing-thats-more-appropriate-for-check-this#comment27258_5319&quot;&gt;in a comment&lt;/a&gt;, because the help page being linked to there now says something about these sorts of close reasons among others. So in some sense this means the answer to the question is &amp;quot;no, we already have a close reason which covers these cases.&amp;quot;&lt;/p&gt;&#xA;&lt;p&gt;However, the close reason in question (&amp;quot;This question does not appear to be about research mathematics within the scope defined in the &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;help center&lt;/a&gt;.&amp;quot;) leaves something to be desired, because it doesn't summarize what list of reasons it actually covers directly -- you have to follow some link and hunt around a bit to get a list of things this close reason &lt;em&gt;might&lt;/em&gt; mean. This is not very helpful either to close-voters or to close-votees.&lt;/p&gt;&#xA;&lt;p&gt;Therefore, I agree that the close reasons could probably use some kind of update, with a few goals:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;The close reasons should be more specific, so that everybody is clear on why exactly a question is being closed.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The specificity of the close reasons should be spelled out in the actual text of the close reason, &lt;em&gt;in addition&lt;/em&gt; to containing links to somewhere these reasons are discussed in more detail.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;With this in mind, I think it's worth opening up the discussion a bit more broadly. If we have 3 slots for close reasons, I think we can reserve one to be a &amp;quot;catch-all&amp;quot; containing a laundry list of reasons and a link to the help page in case we think to add something later, but we have the opportunity to use the other two in a more specific way. Most likely it's worth keeping the second site-specific close reason (directing the user to Math Stack Exchange) in some form at least, which would leave one more slot. If we have one slot for a more specific close reason, what is the best reason for it to be covering?&lt;/p&gt;&#xA;" OwnerUserId="2362" LastEditorUserId="2362" LastEditDate="2022-05-06T18:18:15.390" LastActivityDate="2022-05-06T18:18:15.390" CommentCount="6" ContentLicense="CC BY-SA 4.0" />

Questions about homework are generally &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;off-topic&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Questions about homework are generally &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;off-topic&lt;/a&gt;. MathOverflow is for mathematicians to ask each other questions about their research.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I suspect that one of these reasons at some point replaced the other, as a minor rewording. Judging by &lt;a href=&quot;https://meta.mathoverflow.net/questions/1193/revamping-the-closure-reasons&quot;&gt;this old meta discussion&lt;/a&gt;, it appears that this close reason (containing the word &amp;quot;homework&amp;quot;) was retired in 2013 in favor of the current close reason which mentions Math Stack Exchange. At the time, no specific rationale was recorded for dropping the word &amp;quot;homework&amp;quot;, but I think I agree that explicitly labeling a question as &amp;quot;looking like homework&amp;quot; is not something we want to be doing in our question-closing process.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Why do we close questions, anyway?&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;We have recently revamped the &lt;a href=&quot;https://mathoverflow.net/help/on-topic&quot;&gt;help page&lt;/a&gt; which describes what's on-topic and what's off-topic on MathOverflow, as suggested by Matt F. &lt;a href=&quot;https://meta.mathoverflow.net/questions/5011/revising-the-help-page-on-what-topics-can-i-ask-around-here&quot;&gt;in this meta discussion&lt;/a&gt;. Currently, that help page lists the following possible reasons that a question may be off-topic:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;The question looks like homework.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The question is a discussion question.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The question asks for a broad exposition or encyclopedia article on a topic.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The question asks for OP's or somebody else's work to be checked.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The question is really just an announcement of results.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The question asks a well-known open problem.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The question has been inappropriately cross-posted on another site.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;The question is a meta MathOverflow question.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;In addition, the user is advised to avoid the following types of questions until they gain a bit of familiarity with the site:&lt;/p&gt;&#xA;&lt;ol start=&quot;9&quot;&gt;&#xA;&lt;li&gt;&lt;p&gt;Questions asking for a list of something.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Questions about the workings of the mathematical community rather than about mathematics &lt;em&gt;per se&lt;/em&gt;.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;&lt;strong&gt;Question 1:&lt;/strong&gt; Are we missing any important close reasons here?&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Analysis of Close Reasons Needed:&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;It appears to me that, with a few exceptions, most of the above close reasons are well-covered by the close reasons one is allowed to select when voting to close a question:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;p&gt;Homework -- not about research math.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Discussion -- needs focus / opinion based.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Encyclopedia -- needs focus.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Checking work -- ?? As &lt;a href=&quot;https://meta.mathoverflow.net/questions/5319/could-we-add-another-reason-for-closing-thats-more-appropriate-for-check-this&quot;&gt;suggested&lt;/a&gt; by Gro-Tsen, we could perhaps use a specific close reason for this.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Result announcement -- ?? If the question is not really a question, in principle we shouldn't need a site-specific close reason. Probably &amp;quot;opinion-based&amp;quot; should cover cases like this. But perhaps there's something to be said for having a close reason which allows this to be lumped with &amp;quot;work-checking&amp;quot;.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Open problem -- ?? I think that &amp;quot;needs focus&amp;quot; should cover a case like this -- the point is that if you're asking about an open problem, you should be asking some more specific question than just &amp;quot;what is the solution?&amp;quot;. However, because &amp;quot;needs focus&amp;quot; is not a site-specific close reason, we can't edit it to point out that specifically, questions about open problems need a very particular kind of focus. So perhaps it would make sense to have an additional close reason covering this case.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Cross-post -- &lt;strike&gt; duplicate &lt;/strike&gt; ?? I realize now I'm not sure how we usually handle inappropriate cross-posts.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;Meta -- not about research math.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;(Lists) -- needs focus.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;(Mathematical community) -- not about research math.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;So by my count, there are up to &lt;strike&gt; 3 &lt;/strike&gt; 4 close reasons which could be formalized in addition to the ones we have, but only 1 slot to put them in. So some sort of prioritizing or lumping-together needs to be done.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Question 2:&lt;/strong&gt; Which of the &lt;strike&gt; 3 &lt;/strike&gt; 4 close reasons with question marks above is the most important to give a close reason to? More broadly, what would be the ideal way to use our 3 allotted slots of site-specific close reasons?&lt;/p&gt;&#xA;&lt;p&gt;For example, one possibility would be to keep the two existing close reasons we have, and to additionally add something along the lines &lt;a href=&quot;https://meta.mathoverflow.net/questions/5319/could-we-add-another-reason-for-closing-thats-more-appropriate-for-check-this&quot;&gt;suggested by Gro-Tsen&lt;/a&gt;. In that case, we'd just need to nail down the details a bit more.&lt;/p&gt;&#xA;&lt;p&gt;(Note that there's also the option to provide a custom close reason which you write on the spot. If a close reason is rare enough, it can be covered by that.)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Analysis of the close reasons we have:&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Note also that the two site-specific close reasons we currently have are similar -- one is &amp;quot;not about research math&amp;quot;, while the other is &amp;quot;not about research math, and here's a link to Math.SE&amp;quot;. It seems to me these should be modified to give a little more clarity about when one should be chosen over the other. This leads into the final point.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Technical Point:&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://meta.stackexchange.com/questions/346638/question-close-updates&quot;&gt;Since 2019&lt;/a&gt; we have the flexibility to have the close reasons we use display differently to different users. For instance, the message shown to a prospective close voter can be different from the message shown to a prospective close votee.&lt;/p&gt;&#xA;&lt;p&gt;I bring this up because it may be relevant to us when it comes to the two existing close reasons -- we could consider adding some guidance for close-voters over when to choose the one which links to Math Stack Exchange and when not to (I think the main point is: don't choose the Math Stack Exchange one unless you're sure the question meets the standards of Math Stack Exchange questions.)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Question 3:&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;What specifically should our site-specific close reasons say?&lt;/p&gt;&#xA;&lt;p&gt;This question is mean to include the specifics of any potential new close reasons, as well as any potential changes to the wording of existing close reasons (technically to change the wording, the process is to delete the old close reason and replace it with a new one, but I think we should be open to doing something like that at this time with our existing close reasons.)&lt;/p&gt;&#xA;" OwnerUserId="2362" LastEditorUserId="2362" LastEditDate="2022-07-11T18:59:42.790" LastActivityDate="2022-07-11T18:59:42.790" Title="Revamping the closure reasons in 2022" Tags="|discussion|on-topic|close-reasons|" AnswerCount="2" CommentCount="8" ContentLicense="CC BY-SA 4.0" />

We use urlextract and regular expression to extract links to zbmath.org.&lt;/p&gt;&#xA;&lt;p&gt;The script runs once a day. The links that were found are inserted into our database and displayed at zbmath.org with a delay of usually one day. So in total there is a delay of two days from linking to a zbmath document in a MathOverflow post and the display of the backlink on zbmath.org. (It is possible to reduce this delay. We thought this is not needed.) Revisions of old posts are also considered.&lt;/p&gt;&#xA;&lt;p&gt;Once in a month we run a script to remove invalid MathOverflow links or backlinks to MathOverflow Posts, in which the corresponding zbmath link was deleted. It would also be possible to run this deletion script every day. As we observed that it does not happen that often that backlinks have to be removed, we decided to run it only once in a month.

This is a bug that we will correct.&lt;/p&gt;&#xA;&lt;p&gt;Regarding the original question: There is no policy on formatting links in order for MathOverflow posts to be tracked back in relevant zbMATH Open reviews. We recommend to use the “Insert Citation” button (only available at mathoverflow.net, not on meta.mathoverflow.net). Using this button one can search for a citation string and gets a list of up to three relevant zbmath documents. If the correct document is among the three results one can choose the correct one and the citation will be inserted correctly formatted into the MathOverflow post. However, also links that were pasted by hand should work as long as the zbmath identifier (zbl number or jfm number) occurs in the link. For example,&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://zbmath.org/?q=ti:References+to+research+literature+in+QA+forums&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://zbmath.org/?q=ti:References+to+research+literature+in+QA+forums&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;does not work, but&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://zbmath.org/?q=an:1428.68357&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://zbmath.org/?q=an:1428.68357&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;does work.&lt;/p&gt;&#xA;&lt;p&gt;To make sure the link is recognized, I would advise to use the format zbmath.org/?q=an:&amp;lt;zbl id&amp;gt;. It is also possible to link to several zbmath documents by separating the individual zbmath identifiers using ‘|’. For example:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://zbmath.org/?q=an:1428.68357%7C1422.01015&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://zbmath.org/?q=an:1428.68357|1422.01015&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;If some backlinks do not occur on zbmath.org after two or three days, you can write a mail to editor@zbmath.org and we will investigate the problem.&lt;/p&gt;&#xA;&lt;p&gt;Furthermore, we are working on linking to more websites that are interesting for mathematicians.

But finding the paper just from this paragraph - and from the broken link - would be a bit harder.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;(I would like to make clear that by including the above links I do not want to blame specific users. After all, who could have known that some springerlink or projecteuclid link might stop working. But I wanted to include at least some examples where something similar actually happened. There are probably much more egregious examples - I did not spend that much time searching. In both cases I linked above there was enough additional information in the question or in the answers to actually find the paper.)&lt;/p&gt;&#xA;&lt;p&gt;Additionally, I will mention that adding link to Zbl can lead to link back to the MO post from zbMATH review to the MathOverflow post.

(I've seen a suggestion to modify that close reason in Tim Campion's question and an answer posted there suggests to merge the two close reasons into one. But neither of those two proposals suggest to remove the link to MSE.)&lt;/p&gt;&#xA;&lt;p&gt;I am aware that there were some suggestions to remove the close reason explicitly mentioning Mathematics Stack Exchange. There was a question about back in 2019 which - among other things - mentions this suggestion: &lt;a href=&quot;https://meta.mathoverflow.net/q/4217&quot;&gt;Are we making it too tempting/easy to send inappropriate posts to MSE?&lt;/a&gt; But no answer was posted there - only several comments.&lt;/p&gt;&#xA;&lt;p&gt;I have seen suggestions along these lines in comments. For example, in &lt;a href=&quot;https://meta.mathoverflow.net/posts/comments/27333&quot;&gt;this recent discussion&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;There were also &lt;a href=&quot;https://meta.mathoverflow.net/questions/linked/2319&quot;&gt;several questions&lt;/a&gt; asking what is actually the difference between these two close reasons.

Am I going crazy?'&lt;/p&gt;&#xA;&lt;p&gt;together with the attempted blorp construction and an attempt at proving that it satisfies some lemma (I don't have any specific examples off hand, but I'm confident that a search for 'Lurie HTT' on the main site would produce several).&lt;/p&gt;&#xA;&lt;p&gt;These questions have historically been well-received, but seem like they might fall under the purview of the new close reason -- this is a persons attempted proof that we are being asked to verify. Is this done with intent, i.e. did the moderator team decide that these questions didn't fit at MO and change the close reasons accordingly, or am I misinterpreting the new close reason and applying it too broadly?&lt;/p&gt;&#xA;&lt;p&gt;I'm also curious about (admittedly much less common) situations where some question starts out on MO, the questioner writes a paper about the question that doesn't 'answer' it but is relevant to the question, and then comes back and adds a link to the paper in the question. Would this run afoul of the new close reason?&lt;/p&gt;&#xA;&lt;p&gt;I recently asked a question that got a good amount of views and some positive feedback but no real progress on the question asked.

How should we interpret it as it pertains to linking in papers written about MO questions by the MO asker after the question was originally asked?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Any relevant opinions are appreciated.&lt;/p&gt;&#xA;" OwnerUserId="92164" LastActivityDate="2022-06-07T18:03:07.390" Title="New community close vote reason" Tags="|discussion|close-reasons|" AnswerCount="0" CommentCount="5" ContentLicense="CC BY-SA 4.0" />

I'm assuming that the appearance of an MO question on the Hot Network Questions list probably contributes to this phenomenon; I have a hard time explaining why (as of this writing) there have been almost 100 upvotes on my &lt;a href=&quot;https://mathoverflow.net/a/413476&quot;&gt;answer to a question about the unsolvability of the quintic&lt;/a&gt;, other than that something drove an unusual amount of network traffic to the question.&lt;/p&gt;&#xA;&lt;p&gt;Occasionally we see questions here on meta-MO of the form, &amp;quot;Such-and-such a question was highly upvoted; why was my similar question poorly received?&amp;quot;  If the reason for the high number of upvotes was that the question showed up on HNQ, then the high number of upvotes does not necessarily mean that the primary MO community thinks highly of such questions, but this is difficult to explain to people, especially if it's hard to prove that this is what happened.&lt;/p&gt;&#xA;&lt;p&gt;So, an argument could be made that &amp;quot;widely accessible&amp;quot; but not &amp;quot;research-level&amp;quot; MO questions should not appear on the HNQ list.  But I'm not sure that that judgment is easy to make, and especially not before the flood of upvotes starts to materialize.&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;&lt;b&gt;EDIT 8/7/2022:&lt;/b&gt; Here is some anecdotal evidence this effect is getting more and more pronounced: In the past week, the top five questions (&lt;a href=&quot;https://mathoverflow.net/posts/427842/timeline&quot;&gt;1&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/427704/timeline&quot;&gt;2&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/427804/timeline&quot;&gt;3&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/427942/timeline&quot;&gt;4&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/posts/427891/timeline&quot;&gt;5&lt;/a&gt;) were all hot network questions.  All of them struck me as getting significantly more upvotes than they would have without the hot-network effect.  While this is not necessarily a terrible thing, I have mixed feelings about users who don't normally participate much at MO having such a powerful impact on our site.  On the one hand, advertising cool math to a wider community seems like a good thing in general; on the other hand, it somewhat interferes with the primary purpose of MO.&lt;/p&gt;&#xA;" OwnerUserId="3106" LastEditorUserId="3106" LastEditDate="2022-08-08T02:27:31.813" LastActivityDate="2022-08-08T02:27:31.813" CommentCount="2" ContentLicense="CC BY-SA 4.0" />

Essentially, if a question is highly subjective, then it is likely to generate opinion-based answers. People are going to vote to express their agreement or disagreement with the opinions being expressed (like they will do on this answer). This kind of voting is very different from the voting on a more mathematical question, where a downvote might be used to signify that the mathematics is wrong, or poorly written.&lt;/p&gt;&#xA;&lt;p&gt;In a 2010 discussion on Tea, the community essentially came to the conclusion that Big List questions should be CW so that people can vote in support or disagreement without harming reputation.&lt;/p&gt;&#xA;&lt;p&gt;Hence, I feel the same consideration should apply to questions whose answers are necessarily subjective, like &amp;quot;should we as a field do X?&amp;quot; Or &amp;quot;what should an editor do when ...?&amp;quot; Or &amp;quot;can someone give me a list of the major advances in field Y?&amp;quot; This way, reputation reflects (ideally) the quality of a user's mathematical contributions, and not whether or not the community largely agrees with the user's subjective opinions.&lt;/p&gt;&#xA;" OwnerUserId="11540" LastActivityDate="2022-06-21T06:13:29.007" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

With the current system, it seems feasible to combine them into one reason. The text below does mention Math Stack Exchange, but with enough context to try to dissuade folks from blindly sending people there without regard for the standards of that site.&lt;/p&gt;&#xA;&lt;p&gt;The new close reason looks like this:&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Text displayed to potential close voter:&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;&lt;strong&gt;This question is not about research level mathematics.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;This close reason should be used if a question is either not about mathematics or if it is not of interest to mathematicians. The latter is often the case because the level of the question is not advanced enough, which in general holds for example for student exercises.

More elementary questions about mathematics are on-topic on &lt;a href=&quot;https://math.stackexchange.com/&quot;&gt;Mathematics&lt;/a&gt;, provided they are well-written according to the &lt;a href=&quot;https://math.meta.stackexchange.com/q/9959/&quot;&gt;standards of that site&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;&lt;strong&gt;Text displayed to other users viewing closed post:&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;&lt;strong&gt;This question does not appear to be about research level mathematics within the scope defined in the help center.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;If this question has a research angle which was not noticed before it got closed, then please leave a comment with relevant information and vote to reopen. The same holds if for some other reason you do think that this question is interesting for mathematicians.

Probably one of the disadvantages is that occasionally spammers can post here on meta.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Main question:&lt;/strong&gt; To which extent should we consider spam posts on MathOverflow Meta a problem? Is this problem serious enough to reconsider whether the threshold for posting should be changed back to 5 reputation points?&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;1&lt;/sup&gt;See the FAQ post: &lt;a href=&quot;https://meta.stackexchange.com/q/58587#160292&quot;&gt;What are the reputation requirements for privileges on sites, and how do they differ per site?&lt;/a&gt; (&lt;a href=&quot;https://meta.stackexchange.com/revisions/160292/101&quot;&gt;current revision&lt;/a&gt;) - this is listed among &amp;quot;Site-specific changes&amp;quot;. Related posts on this meta: &lt;a href=&quot;https://meta.mathoverflow.net/q/33&quot;&gt;Allow posting on meta without any reputation for the first week&lt;/a&gt; and &lt;a href=&quot;https://meta.mathoverflow.net/q/3979&quot;&gt;Change reputation required to post on meta back to 5 reputation points&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;&lt;sup&gt;2&lt;/sup&gt;As indicated in the posts linked above, this was used by many users who needed to merge their MO and SE accounts when this site joined the network. Another possible case where this might be useful is when some organization wants to reach out officially (or semi-officially) to the MO community - they can post on meta without any additional barrier. (Perhaps this was somewhat in this direction - although in this case the user who posted the feedback from zbMATH already had sufficient reputation: &lt;a href=&quot;https://meta.mathoverflow.net/q/5326#5335&quot;&gt;Are there policies to respect in order for MathOverflow Q&amp;amp;As to be tracked back in relevant zbMATH Open reviews?&lt;/a&gt;)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;My personal impression is that there was some increase in the number of spam posts on meta recently. (Of course, this might be skewed by the fact that there were several spam answers on meta during this month. Maybe this was just a random fluctuation.)&lt;/p&gt;&#xA;&lt;p&gt;In a sense, there isn't much harm when a spammer posts a spam post here as a question - the question eventually gets removed and the frontpage is not changed at all. However, if spam is posted in an answer to an existing question, the question is bumped to the frontpage. (Of course, one could view this as a good thing - that some long forgotten question gets some additional attention after it is pushed among the posts with recent activity. But at least some of those posts don't really need renewed attention.)&#xA;Regardless of that, even a spam question is a slight nuisance until it is deleted - but it seems that they are removed reasonably quickly.&lt;/p&gt;&#xA;&lt;p&gt;In the previous post about this issue, there was no response from the mods - so I guess that the mods do not really consider this as a problem. Long time ago I asked Shog9 about this, the response &lt;a href=&quot;https://chat.meta.stackexchange.com/transcript/message/7485200#7485200&quot;&gt;was slightly reluctant&lt;/a&gt;: &amp;quot;Yeah; it's a trivial change, but unless y'all are getting a fair bit of noise there's probably no good reason to mess with it.&amp;quot; (Of course, this was a long time ago - and one cannot draw too substantial conclusions from a single message. In any case, if some MO users consider this a problem, the first step would be trying to persuade the MO mods - which might not be easy.)&lt;/p&gt;&#xA;&lt;p&gt;In case it is useful as a reminder, I'll add a link to this post: &lt;a href=&quot;https://meta.mathoverflow.net/q/4259&quot;&gt;What should I do when I see a spam post on MO?&lt;/a&gt; (It works exactly the same on meta - enough spam flags remove the post and obfuscate the content even for the users who have sufficient reputation to see deleted posts.)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Data/statistics.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://meta.mathoverflow.net/tags/data-explorer/info&quot;&gt;SEDE&lt;/a&gt; contains in the type Votes votes spam flags (VoteTypeId=12) and Offensive flags (VoteTypeId=4).

The thing that I noticed in the strictness of this site. I do not think that the female sex can bear this.&lt;/p&gt;&#xA;&lt;p&gt;The female sex can be attracted to any scientific field by being soft and gentle in treatment, unlike the man who tolerates any strict scientific comment. The woman sees any strict scientific comment as something that discourages her. She cannot accept her scientific reality, her behavior is imaginary, emotional, she believes in emotional aspects, even in scientific fields, and this proves the lack of demand for this sex to such sites, especially the abstract sciences.&lt;/p&gt;&#xA;&lt;p&gt;from your (since-deleted) comments here and here on the same post.

The moderator message that you received explains that your comments violated the Code of Conduct, and, as a matter of fact, your violations were so severe that they would normally cause you to be suspended. One person described your comments as &amp;quot;sexist [and] reprehensible,&amp;quot; another described them as &amp;quot;vile,&amp;quot; and another described them as &amp;quot;hate speech.&amp;quot;&lt;/p&gt;&#xA;&lt;p&gt;However, it sounds like you don't understand &lt;em&gt;why&lt;/em&gt; your comments are unacceptable. You've written elsewhere that you want to figure out a way to make the site welcoming for women and that you have no intention of discriminating.

Both of those beliefs are false, which is really quite obvious from the fact that there are a lot of successful women mathematicians and scientists. In my opinion (and it seems that the MathOverflow moderation team agrees with me), the fact that you hold these clearly false and sexist beliefs means that you're not currently qualified to be a moderator.&lt;/p&gt;&#xA;&lt;p&gt;A lot of the other things that you have said are badly phrased. For example, you keep saying the phrase &amp;quot;the female sex,&amp;quot; which sounds pretty disrespectful; it would be much better to say &amp;quot;women&amp;quot; instead. This is merely one example of the many phrases you've written that sound disrespectful.&lt;/p&gt;&#xA;&lt;p&gt;Another problem is that you're ignoring most of the things that people are telling you. You received a message explaining to you, in detail, why your nomination as a moderator was rejected, and your response was to... post a question asking why your nomination as a moderator was rejected. You already have the answer to your question, but you have chosen to ignore that answer and ask for a different answer instead.&lt;/p&gt;&#xA;&lt;p&gt;Besides that, when several people described your comments as sexist, reprehensible, vile, and hate speech, you should have listened to them and thought about what they were telling you. Instead of doing that, you ignored what they were saying. You somehow came to the (completely implausible and, frankly, bizarre) conclusion that the other candidate somehow &amp;quot;used a devile tricks [...] to convince people there that [you] have used bigotry and sexism.&amp;quot;&lt;/p&gt;&#xA;&lt;p&gt;My advice to you is this:&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Stop and listen.&lt;/strong&gt; Speak less and listen more, because most of what you have been saying is false and most of what people have been telling you is true.

I would assume most people act similarly. However, post a question on the topic of Mathematics Education, and suddenly &lt;em&gt;everyone&lt;/em&gt; becomes an expert in Mathematics Education! Questions in Mathematics Education could be very subtle. Just because someone teaches mathematics, it doesn't make them experts in Mathematics Education. Probably many of those who become a Mathematics Education expert as soon as they see a question on that topic, don't have any interest in Mathematics Education, have never faced the challenges of teaching elementary mathematics, or have not thought about possible solutions to such challenges.&lt;/p&gt;&#xA;&lt;p&gt;Yesterday I posted a question tagged Mathematics Education. It was quickly closed. It was judged to be more appropriate for Stack Exchange Mathematics Educators. One person commented that it was not a research level question. Another person started acting up and making irrelevant and off topic comments. Interestingly, nobody attempted to answer the question itself! These people did not have any knowledge on the topic of the question. In fact, the topic &lt;em&gt;is&lt;/em&gt; a research level question in Mathematics Education and the very fact that someone says it is not, shows they have no information about the topic. I like to assume that if a question does not interest someone, they can just skip it without feeling any urge for making hasty comments under the question.&lt;/p&gt;&#xA;&lt;p&gt;The question that I asked was related to Mathematical Maturity. If you try to search the literature in Mathematics Education for Mathematical Maturity you will not find much. Of course you will find the Wikipedia page and a few blogs related to it, but not many research papers. In fact, I only know of an article named &lt;em&gt;Developing Mathematical Maturity&lt;/em&gt; by Lynn Steen (1983) in: The Future of College Mathematics (pp. 99-110), Springer, New York, NY. But the topic is important enough that Terrence Tao and Bill Thurston have written about it. While the phrase Mathematical Maturity does not directly appear in their writings, one can argue that Tao's blog post &lt;em&gt;&lt;a href=&quot;https://terrytao.wordpress.com/career-advice/theres-more-to-mathematics-than-rigour-and-proofs/&quot; rel=&quot;nofollow noreferrer&quot;&gt;There is more to mathematics than rigour and proofs&lt;/a&gt;&lt;/em&gt; and Thurston's &lt;em&gt;&lt;a href=&quot;https://arxiv.org/pdf/math/9404236.pdf&quot; rel=&quot;nofollow noreferrer&quot;&gt;On proof and progress in Mathematics&lt;/a&gt;&lt;/em&gt; address Mathematical Maturity, among other things.&lt;/p&gt;&#xA;&lt;p&gt;Why is Mathematical Maturity important? We often expect our Calculus III students to be &amp;quot;better&amp;quot; than our Pre-Calculus students in learning mathematics. One can argue that by &amp;quot;better&amp;quot; we mean mathematically more mature. Consequently, one way to see whether our Pre-Calculus to Calculus III sequence is working properly or not, is to look at students' development of Mathematical Maturity from Pre-Calculus to Calculus III. Of course, one may say if students passed their Calculus courses, it means they learned, so why do we need to monitor their development of Mathematical Maturity? But those of you who know something about teaching Calculus, know that just because students pass a course doesn't mean they learned it. I submit that a successful Calculus program is one that develops students' Mathematical Maturity by as much as possible.&lt;/p&gt;&#xA;&lt;p&gt;While there is no universal definition for Mathematical Maturity, mathematicians have been using the phrase. The situation reminds me of notions such as &lt;em&gt;naturality&lt;/em&gt; or &lt;em&gt;moduli space&lt;/em&gt; that were used by mathematicians before they had a formal definition. In the case of naturality, MacLane and Eilenberg captured its definition by introducing the notion of natural transformations of functors. Therefore, being able to provide a universally agreeable definition of Mathematical Maturity is a research level question in Mathematical Education, although, that was not what my post was about. Another challenge is to have tools for measuring the development of Mathematical Maturity from Pre-Calculus to Calculus III.&#xA;But who can address these questions about Mathematical Maturity? I would like to argue that one has to be a mathematician to know what Mathematical Maturity means. Terrence Tao would know more about Mathematical Maturity. Bill Thurston would know more about Mathematical Maturity. Mathematicians are the ones who know about Mathematical Maturity. And this is why my question is &lt;em&gt;not&lt;/em&gt; more appropriate for Stack Exchange Mathematics Educators, but appropriate for Mathoverflow, for mathematicians to respond to it (of course, only if the topic interests them). To my point, I recommend reading the report &lt;em&gt;&lt;a href=&quot;http://sigmaa.maa.org/rume/crume2019/Papers/106.pdf&quot; rel=&quot;nofollow noreferrer&quot;&gt;How Do Mathematicians Describe Mathematical Maturity?&lt;/a&gt;&lt;/em&gt; by Kristen Lew, who is a mathematics educator. What do mathematics educators do when they want to research Mathematical Maturity? They interview mathematicians!! Interestingly, she found that none of the four applied mathematicians whom she interviewed had used or knew of the phrase Mathematical Maturity.&lt;/p&gt;&#xA;&lt;p&gt;I would like to repost my question on Mathoverflow (which I deleted after it was closed), but I don't want it to get closed again! I am posting here in meta, with enough explanation for why I think my question should be on Mathoverflow rather than Mathematics Educators, to see if there is enough supporting opinion to keep my question open, if I repost. I don't understand the &amp;quot;anger&amp;quot; toward such questions that some people exhibit! I find it very unwelcoming and I think this is an issue that Mathoverflow personnel should address.

Yours just fell into the first category. Why? You sort of answered it yourself in the passage&lt;/p&gt;&#xA;&lt;p&gt;&lt;em&gt;What do mathematics educators do when they want to research Mathematical Maturity? They interview mathematicians!! Interestingly, she found that none of the four applied mathematicians whom she interviewed had used or knew of the phrase Mathematical Maturity.&lt;/em&gt;&lt;/p&gt;&#xA;&lt;p&gt;The educators (IMHO) are too obsessed with various metrics (from standardized test scores to &amp;quot;mathematical maturity&amp;quot;) when discussing the mathematics development. As a mathematician I view it very differently. You just build your toolbox and become proficient with your tools. That's where the craftsmanship starts and that's where it ends.&lt;/p&gt;&#xA;&lt;p&gt;If it were about carpentry, I would say that some people carry only a hacksaw and an axe, some other add nails, glue, measuring tapes, hammers, screws, etc. to the set while yet others build a whole factory with their own source of electricity, and so on. Also in this metaphor there are people who can build a whole house with nothing but an axe and there are people who cannot make a simple bench without heavy machinery. The tools and the skills accumulate with time and, while there are some connections (like you cannot efficiently use nails without a hammer or a hammer gets new applications when nails are also around), the order in which people acquire them beyond the first basic set is determined by their particular circumstances more than by any inherent logic, the primary driver for acquiring new tools and skills being the tasks that are hard or impossible to do with the current ones (and you often have a choice between using a new tool and using a new skill).&lt;/p&gt;&#xA;&lt;p&gt;What would I call &amp;quot;mathematical maturity&amp;quot; if I were to use this word for anything? Probably my answer would be &amp;quot;understanding one's abilities, limitations, and the possibilities for further development reasonably clearly&amp;quot; (so it is a meta-craft notion for me).&lt;/p&gt;&#xA;&lt;p&gt;I have no idea whether this is what you had in mind or not, but let me attract your attention to one more important thing. In mathematics we do not try to figure out what one might possibly mean by a certain combination of words that is commonly used without an assigned meaning (in fact we try to &lt;em&gt;never&lt;/em&gt; use words without unambiguous assigned meanings in mathematical texts). Instead, we often assign (more or less arbitrarily) names to objects, tricks, ideas, etc. that turn out to be ubiquitous once their underlying meaning/structure becomes crystal clear but too long to explain in full every time they are mentioned. So, the words &amp;quot;mathematical maturity&amp;quot; would appear in our language &lt;em&gt;after&lt;/em&gt; we notice something common in various instances of student mathematical development, extract that common thing, understand what exactly it is and what it is responsible for, and then decide that it is worth having a name and that &amp;quot;mathematical maturity&amp;quot; is a combination of words that we want to use (though, in all honesty, the probability that we would end up calling it &amp;quot;shmarky plaft&amp;quot; is higher). Thus the definition normally arises in mathematics &lt;em&gt;before&lt;/em&gt; the notion, not &lt;em&gt;after&lt;/em&gt; it.&lt;/p&gt;&#xA;&lt;p&gt;What's the point? It is that your phrase&lt;/p&gt;&#xA;&lt;p&gt;&lt;em&gt;I submit that a successful Calculus program is one that develops students' Mathematical Maturity by as much as possible.&lt;/em&gt;&lt;/p&gt;&#xA;&lt;p&gt;sounds totally meaningless, because you don't even yet know what you are talking about when saying &amp;quot;mathematical maturity&amp;quot;, assume (for no apparent reason) that it takes values in a linearly ordered set and the set of all development states is linearly rather than only partially ordered with respect to it, provide no way to measure it, and, above all, offer it as the single objective function by which to measure &amp;quot;success&amp;quot;, while calculus programs serve a whole multitude of conflicting goals (resulting in tool vs. skill, breadth vs. depth, rigor vs. intuition, relevance to an external subject vs. internal logic, and many other dilemmas that one faces even when one tries to teach a single class, forget about planning the whole sequence). It is exactly such proclamations that make many working and teaching mathematicians very skeptical about mathematical education as a discipline up to denying its very existence as a meaningful science (which is sort of a pity because there are some good ideas and even some sound practical advice there, as far as I can judge).&lt;/p&gt;&#xA;&lt;p&gt;IMHO, what we should really do is not to invent various new &amp;quot;measures of success&amp;quot; and argue about their exact meanings, applicability, and importance, but just run small scale experiments to see which techniques do facilitate learning and which do not and share the resulting conclusions. If some technique really works, it will eventually catch and spread by itself. So you want to develop &amp;quot;mathematical maturity&amp;quot; in students and to demonstrate its importance? Fine. Then I don't even care what you mean by it in the most general sense. Just give me one simple example of its instance I should pay attention to and some easy to implement ideas for how to run the class to develop it and I'll give it a try, but I'll judge whether it works or not by seeing how such change influences the values of &lt;em&gt;my&lt;/em&gt; objective functions. If they go up, yeah, I'll want to know more about your ideas, but if they go down, I'd rather stick to my old ways.&lt;/p&gt;&#xA;&lt;p&gt;Well, you wanted a serious response from someone who can (or, at least, could) qualify as a research mathematician with teaching experience, so I tried to provide one.&lt;/p&gt;&#xA;" OwnerUserId="1131" LastActivityDate="2022-10-25T02:55:38.327" CommentCount="7" ContentLicense="CC BY-SA 4.0" />
  <row Id="5490" PostTypeId="2" ParentId="5481" CreationDate="2022-10-26T03:50:02.727" Score="7" Body="&lt;p&gt;Might I point out that &amp;quot;Mathematical maturity&amp;quot; is not a mathematical object, subject to rigorous definition, so it probably shouldn't be argued about by comparing to actual mathematical objects that may or may not have had a rigorous definition before being studied. It's a sociological/psychological/behavioural phenomenon presumably best examined and discussed based on case studies (in case it's not clear, I think I disagree with both fedja and Mahdi, here!) To answer your question about consensus, it's something that has moved over time, influenced also by external factors like the presence of math.SE.&lt;/p&gt;&#xA;&lt;p&gt;In the early days of MO, when it was smaller and the community mostly knew each other either personally or by reputation, then talking about widely disparate questions was ok, in the manner that talking with one's close colleagues at afternoon tea about this that or anything vaguely intersecting the profession is ok. But now MO operates at scale, and allowing all kinds of random questions seems to be viewed as a risk to keeping the noise/signal ratio low. People who are rather famous, like the late Bill Thurston, have asked very &amp;quot;soft&amp;quot; questions in the past, not least because they are known as somebody who thinks deeply about such stuff and written about it to benefit mathematics as a profession outside MO and/or have even formally published such writing. But, and I say this with the utmost respect, more generic mathematicians like us don't have the social capital to get away with asking such a soft question. Is it fair? Maybe not. But it forces people who want to ask a &amp;quot;super-soft&amp;quot; question to work to make the question really tight and high-quality.&lt;/p&gt;&#xA;&lt;p&gt;So I think it in-principle possible that a question such as your might have survived on MO, at least some point in the past, under ideal circumstances. However, the question really does feel like a question about designing mathematical assessment in an education context, so in it's current form it doesn't feel like an MO question. To counter this negative posture, I watched a talk by Tim Gowers at the recent Fields symposium on YouTube, where he touched on matters that included the curious parallels between what an undergrad struggles to grasp in introductory analysis, and what was difficult for some automatic formal proving software that he was involved in designing. The talk was rather clearly a &amp;quot;sociological&amp;quot; talk, but it also described a fairly ambitious loose research program in trying to quantify what &amp;quot;difficulty&amp;quot; and &amp;quot;centrality&amp;quot; meant in mathematics research, via proof assistants, based on an essay by Akshay Venkatesh about the future of computers in maths research. So you have very famous people, in this instance, talking about big vision matters. I can't say what I would do had I seen your question before closing/deletion, but I hope this is food for thought.&lt;/p&gt;&#xA;" OwnerUserId="4177" LastActivityDate="2022-10-26T03:50:02.727" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

I did not find a Wayback Machine snapshot of the MathOverflow version.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;What happens if a question is migrated and then closed&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;When looking into anything related to migration, it might be useful to have a look at the &lt;a href=&quot;/questions/tagged/faq&quot; class=&quot;post-tag moderator-tag&quot; title=&quot;show questions tagged &amp;#39;faq&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;faq&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;faq-container&quot;&gt;faq&lt;/a&gt; post: &lt;a href=&quot;https://meta.stackexchange.com/q/10249&quot;&gt;What is migration and how does it work?&lt;/a&gt; (Or at least at the parts which are important for the problem you're facing.)&lt;/p&gt;&#xA;&lt;p&gt;In this case a question was migrated to another site and then closed - so the section &amp;quot;What causes a migration to be rejected and what happens after?&amp;quot; is relevant here. See also &lt;a href=&quot;https://meta.stackexchange.com/tags/migration-rejection/info&quot;&gt;the corresponding tag-info&lt;/a&gt; on Meta Stack Exchange.&lt;/p&gt;&#xA;&lt;p&gt;Whenever a question is migrated to another Stack Exchange site and it is closed there for some reason &lt;em&gt;other than duplicate&lt;/em&gt;, then the question is returned back to the original site. (There are some exceptions - if you're interested in more intricate details, you can find them in the linked post.)&lt;/p&gt;&#xA;&lt;p&gt;In this specific case it means that MSE users did not have an option to close the question &lt;em&gt;without&lt;/em&gt; returning it back to MO - unless there was a suitable duplicate target on that site. In particular, this means that the suggestion &lt;a href=&quot;https://meta.mathoverflow.net/posts/comments/27864&quot;&gt;given in one of the comments&lt;/a&gt; - that the MSE users should have closed the question without returning it to MO - isn't technically possible.&lt;/p&gt;&#xA;&lt;p&gt;I will explicitly mention that there is a feature request suggesting a different behavior: &lt;a href=&quot;https://meta.stackexchange.com/q/286419&quot;&gt;Fix the counterproductiveness of migration rejections by eliminating them&lt;/a&gt;. Although personally I do not agree with that particular feature request. In any case, this is how the Stack Exchange software works at the moment - so the only option we have as the users is to take into account the limitations of the software.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;What can be done next?&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Actually I do not think there are really that many options.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;If you think that the question is suitable on MO as it is, suggest that it is reopened. I.e., vote for reopening - that will put the question into the reopen review queue.  And if the votes from the review queue do not help to reopen it, you can try to make a reopen request &lt;a href=&quot;https://meta.mathoverflow.net/q/223&quot;&gt;in the designated thread here on meta&lt;/a&gt; - which has the additional advantage that one can explain why they think the question should be reopened and a further discussion can be held in the comments. (However, this doesn't seem to be a suitable option for this specific case.)&lt;/li&gt;&#xA;&lt;li&gt;If you think that the question is suitable on MSE as it is, suggest to the OP that they might repost the question there. If there are some changes, which would improve chances that the repost would be received well on MSE, suggest them to the OP in comments. (But in this case, the migration was already rejected. So it doesn't seem very likely that the question would be received well.)&lt;/li&gt;&#xA;&lt;li&gt;If you think that the question can be improved to be a reasonable MO question, you can suggest the improvements to the OP in the comments.&lt;/li&gt;&#xA;&lt;li&gt;If you think that the question could be changed into a question that would be welcome on MO (or MSE), but you don't think that the OP has sufficient knowledge to formulate  a good enough question, you can post the question yourself. (In such case, it would certainly be polite to mention the original question and include the link - even in situations when the linked question is only visible to 10k+ users.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;strong&gt;Rules about allowed questions can be interpreted in many different ways&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Different people can judge suitability of a question for MO or MSE differently. (To see some examples of this, it suffices to have a look at the recent close and reopen votes reviews - one can see that some reviewers did not agree with the original close/reopen vote and they voted in the review differently. Users with sufficient reputation have access to full history of recent reviews: &lt;a href=&quot;https://mathoverflow.net/review/close/history&quot;&gt;closed votes&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/review/reopen/history&quot;&gt;reopen votes&lt;/a&gt;.&#xA;Other users can get some information about recent reviews using SEDE queries, such as &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1598108/recent-reviews-of-the-given-types?numberOfHits=1000&amp;amp;types=2,6&quot; rel=&quot;nofollow noreferrer&quot;&gt;this one&lt;/a&gt;.) So luck might be a factor, too - it is possible that the question which was deemed unsuitable for MO by some users, would be well received when judged by some other users.&lt;/p&gt;&#xA;&lt;p&gt;This is, to some extent, natural - even if the site has very specific rules on what is and isn't acceptable, various people will understand those rules differently.&#xA;So maybe &amp;quot;&lt;a href=&quot;https://en.wikipedia.org/wiki/I_know_it_when_I_see_it&quot; rel=&quot;nofollow noreferrer&quot;&gt;I know it when I see it&lt;/a&gt;&amp;quot; is a better way to describe how people decide whether a question on MO should be left open - rather than checking some extensive set of rules and guidelines. For example, one can find on MO some questions suitable for the students starting studying at the university level - despite the fact that the site should be only for questions above a certain level. But still, if MO users find such a question interesting, they might decide to keep it on this site.&lt;/p&gt;&#xA;&lt;p&gt;I think this &lt;a href=&quot;https://chat.stackexchange.com/transcript/9369?m=40339035#40339035&quot;&gt;Todd Trimble's comment&lt;/a&gt; describes it quite well: &amp;quot;I think one of the main criteria for &amp;quot;success&amp;quot; at MO is whether the users find a question interesting or challenging; that in itself serves as &amp;quot;self-motivating&amp;quot;. Thus lack of an explicit motivation or setting of context is often seen as forgivable, if the question is perceived as having apparent intrinsic interest already.&amp;quot;&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Soft questions on MO and MSE&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;One should keep in mind that the sites change over time - it is natural that maybe some types of questions which were accepted on a site when it was small are accepted more reluctantly after the traffic gets bigger.  (Basically the same thing was pointed out in David Roberts's to another recent question: &lt;a href=&quot;https://meta.mathoverflow.net/q/5481#5490&quot;&gt;If it doesn't interest you, don't read it!&lt;/a&gt;)&lt;/p&gt;&#xA;&lt;p&gt;In particular, I'd say that both on MSE and MO, soft questions (and big list questions) were more welcome when the sites were relatively new. (You can find some older discussions related to soft questions on this meta, such as: &lt;a href=&quot;https://meta.mathoverflow.net/q/1051&quot;&gt;Crazy idea about soft questions&lt;/a&gt;.)&lt;/p&gt;&#xA;&lt;p&gt;One can check that the questions tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/soft-question&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;soft-question&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;soft-question&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;soft-question-container&quot;&gt;soft-question&lt;/a&gt; had a better chance of succeeding in the early days of this site - and the same seems to be true about &lt;a href=&quot;https://mathoverflow.net/questions/tagged/big-list&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;big-list&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;big-list&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;big-list-container&quot;&gt;big-list&lt;/a&gt;. I have already mentioned some stats in another discussion: &lt;a href=&quot;https://meta.mathoverflow.net/q/5365#5366&quot;&gt;Why are some non-research questions so highly upvoted?&lt;/a&gt; - some of the&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;If we check the percentage of deleted questions tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/soft-question&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;soft-question&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;soft-question&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;soft-question-container&quot;&gt;soft-question&lt;/a&gt; &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1662286/percentage-of-deleted-questions-in-given-tag-per-year?tagname=soft-question#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per year&lt;/a&gt; or &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1162198/percentage-of-deleted-questions-in-given-tag-per-month?Date2=3000-01-01&amp;amp;tagname=soft-question#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per month&lt;/a&gt;, the numbers were definitely lower cca 10 year ago.&lt;/li&gt;&#xA;&lt;li&gt;Both &lt;a href=&quot;https://mathoverflow.net/questions/tagged/soft-question&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;soft-question&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;soft-question&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;soft-question-container&quot;&gt;soft-question&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/questions/tagged/big-list&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;big-list&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;big-list&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;big-list-container&quot;&gt;big-list&lt;/a&gt; have  a  relatively high &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1162425/percentage-of-closed-questions-per-tag?num=100&quot; rel=&quot;nofollow noreferrer&quot;&gt;percentage of closed questions&lt;/a&gt; - even if we &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1334750/percentage-of-closed-questions-per-tag-with-the-exception-of-duplicate-closures?num=100&quot; rel=&quot;nofollow noreferrer&quot;&gt;do not count duplicates&lt;/a&gt;. Interestingly, the percentage of closed soft questions &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1662284/percentage-of-closed-questions-in-given-tag-per-month-including-deleted-posts?tagname=soft-question#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;does not increase over time&lt;/a&gt;.

Perhaps this is due to his prolific use of the site, but more likely I think it is because his writing is clear and he has the ability to provide concise examples that really illustrate a point.&lt;/p&gt;&#xA;&lt;p&gt;For example, his &lt;a href=&quot;https://mathoverflow.net/a/27765/51771&quot;&gt;answer&lt;/a&gt; on a question about Goldbach, where some unique insight is added about the arithmetic hierarchy, and a number of examples are provided. Perhaps this is all obvious for anyone that covers this rigorously in a formal education, but I remember this post giving me a sudden understanding of what the arithmetic hierarchy is &amp;quot;used&amp;quot; for (previously only understanding some vague concepts as outlined on the wikipedia page).&lt;/p&gt;&#xA;&lt;p&gt;And to venture slightly out of bounds, I want to add this clear writing style extends outside of MO, such as some recent lecture notes &amp;quot;&lt;a href=&quot;http://jdh.hamkins.org/a-review-of-the-goedel-fixed-point-lemma-with-generalizations-and-applications/&quot; rel=&quot;nofollow noreferrer&quot;&gt;A Review of the Godel Fixed Point Theorem&lt;/a&gt;&amp;quot; which I will be making use of in a project of my own.&lt;/p&gt;&#xA;&lt;p&gt;So I'd like to thank JDH for taking the time to answer questions in a clear and accessible manner.

So let me address this first. (At least briefly - some of the links below might add a bit more context.)&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Regular users sometimes use this tag for questions which are off-topic or outright spam.&lt;/li&gt;&#xA;&lt;li&gt;MO moderators sometimes use this to remove a tag from the system - by merging&lt;sup&gt;1&lt;/sup&gt; a tag into &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt;. (Of course, they could merge into another tag - but situations where &lt;em&gt;all&lt;/em&gt; questions in the removed tag would fit some of the existing tags are probably rare.)&lt;sup&gt;2&lt;/sup&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;The usage by regular users probably isn't that important - since we're talking about posts which are eventually going to be deleted. So most occurrences of this tag on the site probably come from merging.&lt;/p&gt;&#xA;&lt;p&gt;The usage by mods could be avoided in some cases. There is a process called &lt;a href=&quot;https://meta.stackexchange.com/q/120640&quot;&gt;burnination&lt;/a&gt;&#xA;which removes all occurrences of the tag without bumping. But this can only be done by SE staff - not by the local mods.&lt;sup&gt;3&lt;/sup&gt; (And SE staff is willing to do this only if the tag has already been reasonably cleaned-up. And only for situations which are too big for manual retagging - so basically only for tags with &lt;span class=&quot;math-container&quot;&gt;$\ge50$&lt;/span&gt; questions.)&lt;/p&gt;&#xA;&lt;p&gt;I do not know what is the stance of the moderators now - but looking at the past removals, at least at some point in the past they seemed to prefer merging over burnination.&lt;sup&gt;4&lt;/sup&gt;&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;So to answer your question whether it would be possible to remove the &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt; from MO, the best I can say is: &lt;strong&gt;Yes,&lt;/strong&gt; this is technically possible. But, &lt;strong&gt;no&lt;/strong&gt; I don't think it is likely to happen.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;In principle, the moderators could request from the Stack Exchange staff to burninate tag.&lt;/li&gt;&#xA;&lt;li&gt;But that would require at least some preliminary clean-up and manual retagging. If nothing else, at least retagging the questions which have only this tag. (At the moment, there are &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1684870/finding-questions-tagged-only-with-one-given-tag?tagname=tag-removed&quot; rel=&quot;nofollow noreferrer&quot;&gt;35 such questions&lt;/a&gt;.) But maybe a bit more than that. (All would depend on the response of the SE staff.)&lt;/li&gt;&#xA;&lt;li&gt;Even if the CMs would be willing to burninate the tag, that would seem like a nonsensical move if the tag would be recreated again soon after that. (I.e., if the mods still want to have the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt; at their disposal and to use it as a target for merging. And if MO users want to keep this tag and use it for off-topic questions and for spam.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Disclaimer: This is written from the viewpoint of somebody outside the MO community. I am in no way defending the existence of the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt;. And I am not advocating for the removal of the tag, either. (I will freely admit that I do not like this tag that much - at the same time I think that there are several problems with tags on MO which are worse than the existence of &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt;.)&#xA;I merely tried  to explain how and why it is (or was) being used on MO.&lt;/p&gt;&#xA;&lt;p&gt;In any case, the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt; probably does not cause any actual harm. Still, if some question with this tag is bumped to the frontpage, it is a good idea to remove it manually. (Well, unless the question is very likely to be deleted anyway - for deleted questions the tags matter much less.)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Some additional links where you can find some explanations concerning the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt;:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The &lt;a href=&quot;https://mathoverflow.net/tags/tag-removed/info&quot;&gt;tag-info for tag-removed&lt;/a&gt;.

At the moment it is tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt;. And in fact, if you look at the &lt;a href=&quot;https://mathoverflow.net/posts/9592/revisions&quot;&gt;revision history&lt;/a&gt;, it shows that the original version had this tag. (Merging two tags replaces the tag in the revision history, too.) But if you check the Wayback Machine, you can see that it was tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/calculus&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;calculus&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;calculus&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;calculus-container&quot;&gt;calculus&lt;/a&gt; in &lt;a href=&quot;https://web.archive.org/web/20130419073722/http://mathoverflow.net:80/questions/9592/generalizations-of-standard-calculus&quot; rel=&quot;nofollow noreferrer&quot;&gt;April 2013&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt; in &lt;a href=&quot;https://web.archive.org/web/20131029014517/http://mathoverflow.net/questions/9592/generalizations-of-standard-calculus&quot; rel=&quot;nofollow noreferrer&quot;&gt;October 2013&lt;/a&gt;. So somewhere between these two dates the mods merged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/calculus&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;calculus&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;calculus&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;calculus-container&quot;&gt;calculus&lt;/a&gt; into &lt;a href=&quot;https://mathoverflow.net/questions/tagged/tag-removed&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;tag-removed&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-removed-container&quot;&gt;tag-removed&lt;/a&gt;.

The answers didn't contain formulas, let alone commutative diagrams.&lt;/p&gt;&#xA;&lt;p&gt;But then I realized that you can actually add requirements in your query.

Then I asked to &amp;quot;include commutative diagrams as well&amp;quot;, which indeed happened (see below).&lt;/p&gt;&#xA;&lt;p&gt;Interestingly, the line breaks in the commutative diagrams were done with a single &lt;code&gt;\&lt;/code&gt;, where a double &lt;code&gt;\\&lt;/code&gt; is required. &lt;strong&gt;And the same was the case in the answer by canvas123&lt;/strong&gt;.

Personally, I am still amazed by this tool since sometimes they turn out to be correct, and probably they will even get much better in the next months and years. At some point, it will become very hard to distinguish them from answers written by human beings.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Here is ChatGPT's (wrong) answer to &amp;quot;Write down a detailed proof that  every monoidal abelian category admit an exact, lax monoidal functor to abelian groups. Include commutative diagrams as well.&amp;quot; (since the modal is stochastic, you will probably get a different answer though):&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;First, let us construct an abelian category &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt; as follows:&#xA;the objects of &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt; are the same as those of &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}$&lt;/span&gt;,&#xA;and the morphisms of &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt; are the same as those of&#xA;&lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}$&lt;/span&gt; except that we require them to be strictly additive,&#xA;i.e. &lt;span class=&quot;math-container&quot;&gt;$f + g = h$&lt;/span&gt; implies &lt;span class=&quot;math-container&quot;&gt;$f = h-g$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$g = h-f$&lt;/span&gt;. Composition in&#xA;&lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt; is the same as in &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}$&lt;/span&gt;, and the identity&#xA;morphism on an object &lt;span class=&quot;math-container&quot;&gt;$c$&lt;/span&gt; is the same as the identity morphism in&#xA;&lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}$&lt;/span&gt;.&lt;/p&gt;&#xA;&lt;p&gt;It is straightforward to verify that &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt; is indeed an&#xA;abelian category. To see that it is monoidal, we define the monoidal&#xA;product &lt;span class=&quot;math-container&quot;&gt;$\otimes'$&lt;/span&gt; on &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt; as follows: given two objects&#xA;&lt;span class=&quot;math-container&quot;&gt;$c_1, c_2$&lt;/span&gt; in &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt;, we define &lt;span class=&quot;math-container&quot;&gt;$c_1 \otimes' c_2 = c_1 \otimes c_2$&lt;/span&gt; in &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}$&lt;/span&gt;. Given two morphisms &lt;span class=&quot;math-container&quot;&gt;$f,g$&lt;/span&gt; in&#xA;&lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt;, we define &lt;span class=&quot;math-container&quot;&gt;$f \otimes' g = f \otimes g$&lt;/span&gt; in&#xA;&lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}$&lt;/span&gt;. It is straightforward to check that &lt;span class=&quot;math-container&quot;&gt;$\otimes'$&lt;/span&gt; is&#xA;associative and that &lt;span class=&quot;math-container&quot;&gt;$I' = I$&lt;/span&gt; is the identity object.&lt;/p&gt;&#xA;&lt;p&gt;Since &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt; is an abelian category, it admits an exact,&#xA;faithful functor &lt;span class=&quot;math-container&quot;&gt;$F: \mathcal{C}' \to \mathbf{Ab}$&lt;/span&gt; to the category of&#xA;abelian groups. Since &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt; is monoidal and &lt;span class=&quot;math-container&quot;&gt;$F$&lt;/span&gt; is a functor,&#xA;it is also lax monoidal, meaning that it preserves the monoidal&#xA;structure up to natural isomorphism. In other words, there exist&#xA;natural isomorphisms &lt;span class=&quot;math-container&quot;&gt;$$F(c_1 \otimes' c_2) \cong F(c_1) \otimes F(c_2)$$&lt;/span&gt;&#xA;for all objects &lt;span class=&quot;math-container&quot;&gt;$c_1, c_2$&lt;/span&gt; in &lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt;, and&#xA;&lt;span class=&quot;math-container&quot;&gt;$$F(f \otimes' g) \cong F(f) \otimes F(g)$$&lt;/span&gt; for all morphisms &lt;span class=&quot;math-container&quot;&gt;$f,g$&lt;/span&gt; in&#xA;&lt;span class=&quot;math-container&quot;&gt;$\mathcal{C}'$&lt;/span&gt;. These natural isomorphisms can be represented by the&#xA;following commutative diagrams:&#xA;&lt;span class=&quot;math-container&quot;&gt;$$\begin{array}{ccc} F(c_1 \otimes' c_2) &amp;amp; \stackrel{\cong}{\longrightarrow} &amp;amp; F(c_1) \otimes F(c_2) \ \downarrow  &amp;amp; &amp;amp; \downarrow \ F(c_1) \otimes F(c_2) &amp;amp; \stackrel{\cong}{\longrightarrow} &amp;amp; F(c_1) \otimes F(c_2) \end{array}$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;When you replace &lt;code&gt;\&lt;/code&gt; by &lt;code&gt;\\&lt;/code&gt; in the latter diagram, it looks like this:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$\begin{array}{ccc} F(c_1 \otimes' c_2) &amp;amp; \stackrel{\cong}{\longrightarrow} &amp;amp; F(c_1) \otimes F(c_2) \\ \downarrow  &amp;amp; &amp;amp; \downarrow \\ F(c_1) \otimes F(c_2) &amp;amp; \stackrel{\cong}{\longrightarrow} &amp;amp; F(c_1) \otimes F(c_2) \end{array}$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;" OwnerUserId="2841" LastEditorUserId="2841" LastEditDate="2022-12-09T21:14:19.960" LastActivityDate="2022-12-09T21:14:19.960" CommentCount="13" ContentLicense="CC BY-SA 4.0" />

The formula has less than &lt;span class=&quot;math-container&quot;&gt;$P(n)$&lt;/span&gt; computation steps (that is, it counts partitions in batches), but it is still huge, and I have yet to simplify it. Therefore, I would like to know whether or not other such formulas have been found, in case one of them is the same as mine. If so, I could perhaps spare myself the hassle of pursuing a dead-end/already-explored end/etc. In summary, I just want to know if my discovery is a rediscovery (and thereupon, find out more about the value of the discovery). So, are the formulas that count all the partitions of &lt;span class=&quot;math-container&quot;&gt;$n$&lt;/span&gt; (in batches)?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Is this too vague/broad? It would be a better question if I could  share more, but I do not want to disclose too much information about my research outside of a proper publication.&lt;/p&gt;&#xA;&lt;p&gt;This is how my question looks now:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Does there exist a formula of this form:&lt;/p&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$P(n) = \sum_{i=1}^{x\le P(n)} p_i$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;p&gt;Where &lt;span class=&quot;math-container&quot;&gt;$P(n)$&lt;/span&gt; is the partition function, and the &lt;span class=&quot;math-container&quot;&gt;$p_i$&lt;/span&gt; are batches of partitions of quantity &lt;span class=&quot;math-container&quot;&gt;$\ge 1$&lt;/span&gt;. The sum is just a &lt;strong&gt;closed-form, explicit&lt;/strong&gt; mathematical expression of an algorithm that counts through all the partitions, but given the algorithm's nature, that counting can be somewhat compressed.&lt;/p&gt;&#xA;&lt;p&gt;If no such algorithm has been found, my question defers to whether or not an algorithm for counting partitions one-by-one has been found. I'd think so, but I haven't seen one in my research.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;It has been closed due to lacking clarity. All I want is an explanation for what is missing to give an answer. What is confusing? No-one has explained what is confusing/missing, except for one user saying the answer was trivially yes based on what I find to be a non-sensical reading of the question (that is e.g. &lt;span class=&quot;math-container&quot;&gt;$P(n) = \sum_{k=1}^n P_k(n)$&lt;/span&gt;, thus the answer is yes). I don't see why I have to publish my research just to give a concrete example of a form that seems simple enough.&lt;/p&gt;&#xA;" OwnerUserId="493854" LastEditorUserId="493854" LastEditDate="2022-12-19T14:41:17.743" LastActivityDate="2022-12-19T14:41:17.743" Title="Is this question about partition numbers too broad/vague?"

So you can look at the &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1689204/posts-with-the-most-edits-by-the-op&quot; rel=&quot;nofollow noreferrer&quot;&gt;number of edits by the OP&lt;/a&gt;.

(One of the parameters is there to restrict this to users having at least n posts.)&lt;/li&gt;&#xA;&lt;li&gt;If you want to see number of edits on a post by a specific user - for example, your own posts - you can use &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1689235/number-of-revisions-on-posts-by-a-specific-user?num=500&amp;amp;userid=1532&amp;amp;types=1,2&quot; rel=&quot;nofollow noreferrer&quot;&gt;this query&lt;/a&gt;. (I have used myself as an example - but you can simply change the parameter userid.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;strong&gt;Other related feature requests.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Some suggestions that something like having edits which would not bump the post to the frontpage were posted in the past - with various proposals how to deal with them.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;On this meta: &lt;a href=&quot;https://meta.mathoverflow.net/q/192&quot;&gt;Minor edits, subject to review&lt;/a&gt;. The poster was a moderator at the time. The same suggestion was repeated here: &lt;a href=&quot;https://meta.mathoverflow.net/q/1053#1092&quot;&gt;Big list of feature requests and suggestions for a fantasy MO 3.0&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;On Meta Stack Exchange there is, for example: &lt;a href=&quot;https://meta.stackexchange.com/q/122567&quot;&gt;Allow non-bumping minor edits, but review them on /review&lt;/a&gt;. Many of the &lt;a href=&quot;https://meta.stackexchange.com/questions/linked/122567&quot;&gt;questions linked there&lt;/a&gt; deal with somewhat similar topics.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;If you consider those suggestion useful, you might upvote them - at least to signal support, if SE considers implementing some of them at some future point.&lt;/p&gt;&#xA;&lt;p&gt;Although it seems that the main concern in those discussions is edits on the posts made by other users.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Workarounds in the current situations.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Still, if somebody is running into the problems with the number of edits, they might try to limit it in various ways. If nothing else, one could try to fix multiple things at the same time - one way to do that would be to keep a copy of the post elsewhere, where edits are not disruptive; and only update the MO post after several edits on the other copy.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;One could simply keep the post locally on their computer.&lt;/li&gt;&#xA;&lt;li&gt;One could use some editor which supports the same (or at least similar) syntax as Stack Exchange. I am familiar with StackEdit - but probably there are other suitable options, too.&#xA;See also: &lt;a href=&quot;https://meta.mathoverflow.net/q/3283&quot;&gt;Is here something like blog service or just sand-box to store notes ?&lt;/a&gt;. And on Mathematics Meta: &lt;a href=&quot;https://math.meta.stackexchange.com/q/12967&quot;&gt;MathJax WYSIWYG Editor&lt;/a&gt;, &lt;a href=&quot;https://math.meta.stackexchange.com/q/4735&quot;&gt;MathJax: better way to prepare a Math.StackExchange question?&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;On Mathematics Meta there is this post: &lt;a href=&quot;https://math.meta.stackexchange.com/q/4666&quot;&gt;Sandbox for drafts of long, complex posts&lt;/a&gt;. (I am not sure to which extent this can be considered MO analogoue: &lt;a href=&quot;https://meta.mathoverflow.net/q/55&quot;&gt;Formatting Sandbox&lt;/a&gt;.) This is probably only useful &lt;em&gt;before&lt;/em&gt; posting the first version.&lt;/li&gt;&#xA;&lt;li&gt;This is probably not optimal, but at least in theory one could post a question and then an answer. After deleting both of them, they could serve for them as a &amp;quot;personal sandbox&amp;quot;. (It is not possible to edit a self-deleted question - but one can edit their deleted answers. If the question is deleted too, this won't disrupt the frontpage. However, I am not sure whether or not this usage of deleted posts is frowned upon.) I will explicitly mention that if a question is not deleted, editing a deleted answer still bumps the question. (I am mentioning this mainly because editing an answer while it is deleted was &lt;a href=&quot;https://meta.mathoverflow.net/posts/comments/28119&quot;&gt;suggested in the comments&lt;/a&gt;.)&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Another thing which one could use would be using &lt;a href=&quot;https://meta.mathoverflow.net/tags/saves/info&quot;&gt;saves&lt;/a&gt;. (This feature is relatively new.)&#xA;One could keep here one list with posts which need updating. This feature allows to add a private note to each post in the list - which would be a suitable place where to note what exactly needs updating. And then simply edit several things at the same time.&lt;/p&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2022-12-19T08:50:28.803" LastActivityDate="2022-12-19T08:50:28.803" CommentCount="1" ContentLicense="CC BY-SA 4.0" />

Such links can be created outside the Stack Exchange network - if somebody simply creates a picture on imgur. But some of them might have been uploaded through the Stack Exchange interface. Currently such links will have &lt;a href=&quot;https://mathoverflow.net/search?tab=active&amp;amp;q=url%3a%22%2Ai.stack.imgur.com%2A%22&quot;&gt;the format i.stack.imgur.com&lt;/a&gt; rather than &lt;a href=&quot;https://mathoverflow.net/search?tab=active&amp;amp;q=url%3a%22%2Ai.imgur.com%2A%22&quot;&gt;a link to i.imgur.com&lt;/a&gt;. But this was not always the case.&lt;/p&gt;&#xA;&lt;p&gt;As far as I can tell, at some point there were two changes to the way images are uploaded in the Stack Exchange editor. Since August 2010, Stack Exchange can upload to an imgur account which is not subject to 6 months limit - making them more-or-less permanent.&lt;sup&gt;1&lt;/sup&gt;&#xA;This also led to changing the format of the links from &lt;code&gt;i.imgur.com&lt;/code&gt; to &lt;code&gt;i.stack.imgur.com&lt;/code&gt;. Stack Exchange updated the links from the old format to the new one network-wide.&lt;sup&gt;2&lt;/sup&gt;&lt;/p&gt;&#xA;&lt;p&gt;All of this happened before MathOverflow joined the Stack Exchange network. So the update by the Stack Exchange team did not influence MathOverflow. Was such an update perhaps done by the MO mods at the time? Or was it done by SE after MO joined the network?&lt;/p&gt;&#xA;&lt;p&gt;It seems that there are still at least some links to &lt;code&gt;i.imgur.com&lt;/code&gt; which could be fixed by &lt;code&gt;i.stack.imgur.com&lt;/code&gt;.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Questions.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;What are the reasons for the broken &lt;code&gt;i.imgur.com&lt;/code&gt; links which are supposed to be in the format &lt;code&gt;i.stack.imgur.com&lt;/code&gt;? Is it likely that there are many such links? Or are these examples only some rare exceptions?&lt;/li&gt;&#xA;&lt;li&gt;Is it possible to find all links of this type? (I.e., the links where simply changing the URL to &lt;code&gt;i.stack.imgur.com&lt;/code&gt; would fix the picture.)&lt;/li&gt;&#xA;&lt;li&gt;Was a clean-up of imgur links done on MathOverflow at some point? (Similar as the clean-up done on other sites - which were part of the network in 2010.)&lt;/li&gt;&#xA;&lt;li&gt;Can such links be fixed only manually? Or is it possible to do this automatically.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;I suppose that there are only a very few posts of this type. Search returns only &lt;a href=&quot;https://mathoverflow.net/search?tab=active&amp;amp;q=url%3a%22%2Ai.imgur.com%2A%22&quot;&gt;111 posts with such links&lt;/a&gt;.

previously suspended, when a user is recreated after being destroyed for spam or abuse, and when a network-wide suspension is in effect on an account.&lt;/p&gt;&#xA;&lt;p&gt;³ A &amp;quot;destroyed&amp;quot; user is deleted along with all that they had posted: questions, answers, comments. &lt;a

spam.&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;⁴ This counts every review that was submitted (not skipped) - so the 2 suggested edits reviews needed to approve an edit would count as 2, the goal being to indicate the frequency of moderation actions. This also applies to flags, etc.&lt;/p&gt;&#xA;&lt;p&gt;⁵ Includes close flags (but &lt;em&gt;not&lt;/em&gt; close or reopen votes). Community can handle these flags by at least one person voting to close a question that has a close flag.&lt;/p&gt;&#xA;&lt;p&gt;⁶ This ignores numerous deletions that happen automatically in response to some other action.&lt;/p&gt;&#xA;&lt;p&gt;⁷ This includes comments deleted by their own authors (which also account for some number of handled comment flags).&lt;/p&gt;&#xA;&lt;h3&gt;Further reading:&lt;/h3&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;Wanna see how these numbers have changed over time?

Number of all users will, for example, include spambots or users who registered here and never did anything else. The question is, what does it mean that a user is &lt;em&gt;active&lt;/em&gt; - I have tried using &amp;quot;posting at least one comment&amp;quot; or &amp;quot;creating at least one post&amp;quot; as a proxy.&lt;/p&gt;&#xA;&lt;p&gt;I will reuse the queries from &lt;a href=&quot;https://meta.mathoverflow.net/questions/4505/does-the-number-of-answers-really-drop-over-years/4510#4510&quot;&gt;another answer&lt;/a&gt;:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;How many users created at least one post &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1214820/number-of-users-with-at-least-one-post-monthly?Date1=2000-01-01&amp;amp;Date2=3000-01-01#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;in the given month&lt;/a&gt; or &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702495/number-of-users-with-at-least-one-post-per-year#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;in the given year&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;How many users posted at least one comment &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1214815/number-of-users-with-at-least-on-comment-monthly?Date1=2000-01-01&amp;amp;Date2=3000-01-01#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;in the given month&lt;/a&gt; or &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702496/number-of-users-with-at-least-on-comment-per-year#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;in the given year&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;It is worth mentioning that users with sufficient reputation have access to &lt;a href=&quot;https://mathoverflow.net/help/privileges/site-analytics&quot;&gt;site analytics&lt;/a&gt; where they can see traffic - statistics about visits and page views. A screenshot from 2017 can be seen in &lt;a href=&quot;https://meta.mathoverflow.net/questions/3356/the-number-of-on-line-users-at-a-given-moment/3359#3359&quot;&gt;another answer&lt;/a&gt; here on meta.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;&lt;strong&gt;Number of all users&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Here are queries showing how many accounts were created &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702484/number-of-created-user-accounts-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per month&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702485/number-of-created-user-accounts-per-year#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per year&lt;/a&gt;. (I will explicitly mention that the users who have deleted their accounts in the meantime are not counted here.)&lt;/p&gt;&#xA;&lt;p&gt;We probably want to see the total number of users who created their accounts until the given date.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;This query should show the total number of accounts created &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702491/total-number-of-users-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per month&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702494/total-number-of-users-per-year#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per year&lt;/a&gt;.&lt;/li&gt;&#xA;&lt;li&gt;As another attempt I tried to take rene's query from an answer on Meta Stack Exchange and to modify it to count users: &lt;a href=&quot;https://meta.stackexchange.com/q/248396#248413&quot;&gt;How can I get stats for the total number of questions and answers posted so far vs. time?&lt;/a&gt; This is what I get if I use &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702481/the-total-number-of-users-accounts-so-far-vs-time?increments=30&amp;amp;results=400#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;30 days&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702481/the-total-number-of-users-accounts-so-far-vs-time?increments=365&amp;amp;results=20#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;365 days&lt;/a&gt; as the increment in that query.&lt;/li&gt;&#xA;&lt;li&gt;If users' ids were assigned consecutively from 1 to the most recent user, we could simply look at the maximum of userid. But this does not really work - as you can see in the queries showing the maxima and the minima &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702504/maximal-userid-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per month&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1702505/maximal-userid-per-month#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;per year&lt;/a&gt;. I do not have some better explanation for the jumps in this graph other than they might be caused by merging accounts (where an older account might suddenly get higher user id if it was merged with a newer account.) For this reason, it might be better to look at the minima. Still, this will be an overestimate - as the id's are probably not necessarily consecutive.

Refreshing a page repeatedly, without changing anything else, will often cause the bug to appear and disappear.  Sometimes the number will show while the page is loading, but then disappear while the load is complete.  The preview while editing is also often different from the rendered result.&lt;/p&gt;&#xA;&lt;pre&gt;&lt;code&gt;1. &lt;span class=&quot;math-container&quot;&gt;$$1 + 1 = 2.$$&lt;/span&gt;&#xA;&lt;/code&gt;&lt;/pre&gt;&#xA;&lt;p&gt;produces&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;span class=&quot;math-container&quot;&gt;$$1 + 1 = 2.$$&lt;/span&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;For me, that usually looks like this:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/f2Pnl.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/f2Pnl.png&quot; alt=&quot;Numbered list's number is swallowed&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;Notice that the number was swallowed.  I would have expected it to behave like&lt;/p&gt;&#xA;&lt;pre&gt;&lt;code&gt; 1.&#xA; &lt;span class=&quot;math-container&quot;&gt;$$1 + 1 = 2.$$&lt;/span&gt;&#xA;&lt;/code&gt;&lt;/pre&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$1 + 1 = 2.$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;p&gt;(For me, the latter always shows the number and the displayed equation on separate lines, which is what I think most TeX users would expect.  As @DavidRoberts &lt;a href=&quot;https://meta.mathoverflow.net/questions/5583/in-safari-on-macos-a-numbered-list-beginning-with-a-displayed-equation-swallows#comment28295_5583&quot;&gt;mentions&lt;/a&gt;, this different behaviour does not occur on Firefox.  As &lt;a href=&quot;https://meta.mathoverflow.net/questions/5583/in-safari-on-macos-a-numbered-list-beginning-with-a-displayed-equation-swallows#comment28296_5583&quot;&gt;I&lt;/a&gt; and @AsafKaragila &lt;a href=&quot;https://meta.mathoverflow.net/questions/5583/in-safari-on-macos-a-numbered-list-beginning-with-a-displayed-equation-swallows#comment28298_5583&quot;&gt;mentioned&lt;/a&gt;, Chrome seems to behave differently, putting the first equation on the same line as the number.

Moreover, I checked that I can access the question when I log out, but after I log back in, it’s broken again. This happens consistently across multiple devices (albeit on the same network).&lt;/p&gt;&#xA;&lt;p&gt;The associated &lt;a href=&quot;https://mathoverflow.net/posts/54735/timeline&quot;&gt;timeline&lt;/a&gt; and &lt;a href=&quot;https://mathoverflow.net/posts/54735/revisions&quot;&gt;revisions&lt;/a&gt; pages work fine.&lt;/p&gt;&#xA;&lt;p&gt;The same problem affects many more questions. As observed by &lt;a href=&quot;https://meta.mathoverflow.net/questions/5584/kitty-can-t-fix-it-old-questions-inaccessible-for-logged-in-users-giving-une#comment28325_5584&quot;&gt;Sam Hopkins&lt;/a&gt;, they all seem to be &lt;span class=&quot;math-container&quot;&gt;$\ge10$&lt;/span&gt; years old. &lt;a href=&quot;https://meta.mathoverflow.net/questions/5584/kitty-can-t-fix-it-old-questions-inaccessible-for-logged-in-users-giving-une#comment28363_5584&quot;&gt;Martin Sleziak&lt;/a&gt; found out an important distinguishing feature that all affected question have some deleted answers. Moreover, evidence suggests that the bug only happens for users with &lt;span class=&quot;math-container&quot;&gt;$\ge10$&lt;/span&gt;k reputation (possibly because they can see deleted answers).&lt;/p&gt;&#xA;&lt;p&gt;It appears from &lt;a href=&quot;https://meta.mathoverflow.net/questions/5584/kitty-can-t-fix-it-old-questions-inaccessible-for-logged-in-users-giving-une#comment28368_5584&quot;&gt;quick sampling&lt;/a&gt; that about 2/3 of all old questions with deleted answers are affected by this bug, which means it’s likely &lt;strong&gt;several thousands&lt;/strong&gt; of questions.&lt;/p&gt;&#xA;&lt;p&gt;As for the cut-off date, the last question affected by the bug that I found is &lt;a href=&quot;https://mathoverflow.net/questions/134595/computing-ext-in-exterior-algebra-related-to-koszul-duality&quot;&gt;Computing Ext in Exterior algebra (related to Koszul duality)&lt;/a&gt; from June 24, 2013, which is the day before the integration of MathOverflow into the Stack Exchange network. Thus, it seems likely that the bug only affects questions from before the migration.&lt;/p&gt;&#xA;&lt;p&gt;Based on further experiments, it appears a more precise criterion is that the bug affects questions that have a deleted answer that was deleted by June 24, 2013, except when the answer was deleted in a special way (e.g., &lt;a href=&quot;https://mathoverflow.net/questions/132473/n-balls-covering-n-balls&quot;&gt;here&lt;/a&gt; the answer was converted to a comment; &lt;a href=&quot;https://mathoverflow.net/questions/49303/mazurs-unpublished-manuscript-on-primes-and-knots&quot;&gt;here&lt;/a&gt; it was deleted by spam flags).&lt;/p&gt;&#xA;&lt;p&gt;A small sample of questions exhibiting the problem as reported in the comments:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://mathoverflow.net/questions/2014/if-you-break-a-stick-at-two-points-chosen-uniformly-the-probability-the-three-r&quot;&gt;If you break a stick at two points chosen uniformly, the probability the three resulting sticks form a triangle is 1/4.

MathOverflow is a bit different from other question &amp;amp; answer stack exchange sites. For other sites, helping people quickly find answers is the main goal, and so it makes sense to only close a question when you can point them to an answer. But, while answering questions is of course also an important goal on MO, I would say there are other goals as well. The participants in MO are potentially engaging in math research. One important aspect of academic research is acknowledging priority. Moreover, in math, questions themselves are valued as contributions. So, at a minimum, it is important to acknowledge priority in question-asking.&lt;/p&gt;&#xA;&lt;p&gt;I also see MathOverflow as a repository of mathematics knowledge. Over time, the database of both questions and answers grows, and people who want to learn can search (either on MathOverflow itself or e.g. via Google) to find that a question they have may have already been asked and/or answered.

I wish I had the specific example on hand, but I remember recently reading a question where the asker acknowledged that it was a duplicate of an old (maybe ~10 years old), unanswered MO question. They wanted to re-ask the question in case there have been any updates in the field which may have lead to it being answerable now even though it wasn't before. I think this is totally fine, especially when you acknowledge the previous question. But for example on the other hand, the question I linked above was a duplicate of a question that was asked only a week ago, so it definitely was not contributing anything new to MO.&lt;/p&gt;&#xA;" OwnerUserId="25028" LastActivityDate="2023-03-30T23:03:37.627" CommentCount="0" CommunityOwnedDate="2023-03-30T23:03:37.627" ContentLicense="CC BY-SA 4.0" />

Giving and receiving acknowledgement is one of the most benign additions to conversation, and it's clearly separated from the more professional Q&amp;amp;A aspect of the site.&lt;/p&gt;&#xA;&lt;p&gt;More generally, comments provide a social outlet for the less professional interactions. In a positive context, this is used to ask/receive clarifications. But even this provides a &amp;quot;social&amp;quot; interaction between two people, and positive/helpful such interactions encourage people to return. Even seeing secondhand a clarification-and-answer in comments or a &amp;quot;thanks&amp;quot; gives the appearance of a somewhat &amp;quot;warm&amp;quot; community.&lt;/p&gt;&#xA;&lt;p&gt;Professionalism and formal conduct has its place, especially when trying to resolve knowledge questions, but I would caution that being overly strict or overly formal has detrimental effects to building a community.

It is my favorite comment chain on MO (about Heisenbert and Heisenernie), and I hope it remains forever. It was a serious answer with a simple typo that is unlikely to be confused with anyone, and it spawned a couple of silly comments that have remained for 10+ years now.

Indeed, the OP seems to feel similarly, and plans to delete the question.&lt;/p&gt;&#xA;&lt;p&gt;Now, initially, the question did not have these disclaimers.  The first version pretty much just asked, &amp;quot;Is this paper correct?&amp;quot; and as such seems like a clear candidate for closure, per MO's usual policy.  Later versions added some specific mathematical content, and it looked like it might be headed toward an acceptable MO question, but in every revision, the main question was still &amp;quot;Is this paper correct?&amp;quot; and not the actual math.  I think I would have voted to close every revision.&lt;/p&gt;&#xA;&lt;p&gt;Having said all that, I think it's still possible that this question could be turned into an acceptable one, if the &amp;quot;Is this paper correct?&amp;quot; part is deleted and the focus is on a specific mathematical claim in the paper that turns out to be subtly wrong.

I cannot think of any appropriate tags on this site that refer to specific products, and I do not believe that it is appropriate to have tags on this site about specific products. Tags on this site are uncapitalized, and since the tags on this site are uncapitalized, this site favors tags which are not proper nouns. Bitcoin is a proper noun when referring to the cryptocurrency network, so we should not use the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/bitcoin&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;bitcoin&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;bitcoin&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-bitcoin-tooltip-container&quot;&gt;bitcoin&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;The tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/bitcoins&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;bitcoins&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;bitcoins&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-bitcoins-tooltip-container&quot;&gt;bitcoins&lt;/a&gt; does not seem like the best tag since it seems like even the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/bitcoin&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;bitcoin&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;bitcoin&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-bitcoin-tooltip-container&quot;&gt;bitcoin&lt;/a&gt; is an improvement over &lt;a href=&quot;https://mathoverflow.net/questions/tagged/bitcoins&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;bitcoins&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;bitcoins&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-bitcoins-tooltip-container&quot;&gt;bitcoins&lt;/a&gt;. The term 'Bitcoin' with an upper-case 'B' refers to the entire cryptocurrency blockchain while the term 'bitcoin' with a lower-case 'b' refers to a specific unit of currency worth $28,175.32 as of 5/1/2023 in the Bitcoin blockchain. The term 'bitcoins' is the plural form of 'bitcoin'. We can therefore conclude that the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/bitcoins&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;bitcoins&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;bitcoins&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-bitcoins-tooltip-container&quot;&gt;bitcoins&lt;/a&gt; refers to the plural of 'bitcoin' which refers to a quantity of digital currency instead of the blockchain. It is more appropriate for the tag to refer to the entire blockchain than to a specific unit of currency on that blockchain.&lt;/p&gt;&#xA;&lt;p&gt;The tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/bitcoins&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;bitcoins&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;bitcoins&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-bitcoins-tooltip-container&quot;&gt;bitcoins&lt;/a&gt; is outdated in favor of the more appropriate tags &lt;a href=&quot;https://mathoverflow.net/questions/tagged/cryptocurrencies&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;cryptocurrencies&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;cryptocurrencies&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-cryptocurrencies-tooltip-container&quot;&gt;cryptocurrencies&lt;/a&gt;, &lt;a href=&quot;https://mathoverflow.net/questions/tagged/proof-of-work&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;proof-of-work&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;proof-of-work&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-proof-of-work-tooltip-container&quot;&gt;proof-of-work&lt;/a&gt;, and &lt;a href=&quot;https://mathoverflow.net/questions/tagged/cryptography&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;cryptography&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;cryptography&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-cryptography-tooltip-container&quot;&gt;cryptography&lt;/a&gt;. The tag 'bitcoins' was created in September 5, 2012. In 2012, Bitcoin's market capitalization completely dominated the total cryptocurrency market capitalization. Only in 2017 did we see Bitcoin's percentage of the total cryptocurrency market capitalization drop from about 85 percent to about 33 percent. Bitcoin's percentage of the total cryptocurrency market capitalization has been around 50 percent since the middle of 2017 (take this value with a grain of salt since it does not take into consideration lost bitcoins). Right now there are thousands of alternate cryptocurrencies to choose from besides Bitcoin, but in 2012, Bitcoin was the only cryptocurrency that was not just an experiment. It made more sense to use a 'Bitcoin' tag in 2012, but now it does not make sense to use the &lt;a href=&quot;https://mathoverflow.net/questions/tagged/bitcoin&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;bitcoin&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;bitcoin&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-bitcoin-tooltip-container&quot;&gt;bitcoin&lt;/a&gt; tag in favor of &lt;a href=&quot;https://mathoverflow.net/questions/tagged/cryptocurrencies&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;cryptocurrencies&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;cryptocurrencies&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-cryptocurrencies-tooltip-container&quot;&gt;cryptocurrencies&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;The site &lt;a href=&quot;https://crypto.stackexchange.com/tags&quot;&gt;https://crypto.stackexchange.com/tags&lt;/a&gt; does not have a tag for Bitcoin. The Cryptography Stack Exchange site has thought about the usage of the Bitcoin tag, and they have decided that it is best not to use a 'bitcoin' or 'bitcoins' tag, and I agree with their determination.&lt;/p&gt;&#xA;&lt;p&gt;There are several StackExchange sites dedicated to cryptocurrency technologies including Bitcoin, Cardano, Cryptography, Ethereum, Iota, Monero, Stellar, and Tezos. Since the rest of the StackExchange network embraces cryptocurrency technologies, MathOverflow should at least be welcoming to those who ask high quality mathematical questions related to cryptocurrency technologies on this site. Those other sites have not attracted low quality posts, so I doubt that a cryptocurrency tag would attract much more than its fair share of low-quality posts. But I understand that cryptocurrency technologies have been controversial and have unfortunately attracted too many bad actors, so some people on this site may not want anything to do with cryptocurrency technologies. I am in favor of using the tags &lt;a href=&quot;https://mathoverflow.net/questions/tagged/proof-of-work&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;proof-of-work&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;proof-of-work&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-proof-of-work-tooltip-container&quot;&gt;proof-of-work&lt;/a&gt; or &lt;a href=&quot;https://mathoverflow.net/questions/tagged/cryptography&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;cryptography&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;cryptography&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-cryptography-tooltip-container&quot;&gt;cryptography&lt;/a&gt; instead of &lt;a href=&quot;https://mathoverflow.net/questions/tagged/cryptocurrencies&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;cryptocurrencies&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;cryptocurrencies&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-cryptocurrencies-tooltip-container&quot;&gt;cryptocurrencies&lt;/a&gt; since the cryptocurrency related questions on this site have all been about proof-of-work problems which are cryptographic protocols; it is better to use a more specific tag rather than the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/cryptocurrencies&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;cryptocurrencies&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;cryptocurrencies&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-cryptocurrencies-tooltip-container&quot;&gt;cryptocurrencies&lt;/a&gt; which the people on this site have different opinions about.

That is, you can use &lt;code&gt;\*abc\*&lt;/code&gt; to get *abc* without the asterisks having their usual property of italicizing the letters between them.&lt;/p&gt;&#xA;&lt;p&gt;Because of this, when you enter &lt;code&gt;\(&lt;/code&gt; Markdown converts that to just &lt;code&gt;(&lt;/code&gt; in the HTML page, and so this would mean that MathJax (which runs in the browser, well after Markdown has removed the backslashes) only sees regular parentheses, not &lt;code&gt;\(&lt;/code&gt; and &lt;code&gt;\)&lt;/code&gt;.  In order to get &lt;code&gt;\(... \)&lt;/code&gt; into the HTML output where MathJax can pick it up, you would need to enter &lt;code&gt;\\(...\\)&lt;/code&gt; in the editor, so that Markdown would turn &lt;code&gt;\\&lt;/code&gt; into &lt;code&gt;\&lt;/code&gt; and send &lt;code&gt;\(...\)&lt;/code&gt; to the browser.&lt;/p&gt;&#xA;&lt;p&gt;Note, however, that the configuration uses javascript strings, and javascript strings use backslashes as escape characters as well.

That would mean you would have to type &lt;code&gt;\\\\(...\\\\)&lt;/code&gt; in the editor in order to get &lt;code&gt;\\(...\\)&lt;/code&gt; into the HTML resulting HTML page, in order to have the right delimiters for this configuration.&lt;/p&gt;&#xA;&lt;p&gt;So you (and @IsabelBeckenbach) are right that the configuration is incorrect, but you have the wrong reason.  It's not about regular expressions, it is about the Markdown processing that happens to the text you enter before it goes to the browser where MathJax sees it.&lt;/p&gt;&#xA;&lt;p&gt;The &lt;code&gt;displayMath&lt;/code&gt; configuration that uses &lt;code&gt;[&amp;quot;\\[&amp;quot;, &amp;quot;\\]&amp;quot;]&lt;/code&gt; does mean that the delimiters are &lt;code&gt;\[...\]&lt;/code&gt; and so you can get this in Markdown by typing &lt;code&gt;\\[...\\]&lt;/code&gt; in the editor.&lt;/p&gt;&#xA;&lt;p&gt;Still, all of these are harder (and less intuitive since you have to deal with Markdown escaping) than &lt;code&gt;$...$&lt;/code&gt; and &lt;code&gt;$$...$$&lt;/code&gt;.  It would still be nice if StackExchange did fix the incorrect configuration, however, for those who prefer to use the escaped backslash delimiters.

A security team helps us deal with those, and helps ensure that our passwords and private data (e.g. the IP addresses from which you accessed the site each time, which can tell hackers your address, your choices of hotels and locations of travel, the family members you visit as long as you view MathOverflow from your phone while there, etc.) are somewhat safe. Having SE-level security will likely not be cheap. &lt;a href=&quot;https://stackexchange.com/about/security&quot;&gt;Here's a list of security vulnerabilities that were found by non-MO users of SE over the years&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://stackexchange.com/performance&quot;&gt;SE currently uses&lt;/a&gt; 600,000 web sockets, 3 elasticsearch servers (128GB of RAM each), two redis servers (256GB of RAM each), about 2 SQL servers (768GB of RAM each), 9 web servers (64GB of RAM each), and deals with a transfer of 55 TB of data per month. MO will not need that much, but &lt;strong&gt;running and maintaining servers has a cost.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Web development is also a constantly changing occupation. My first website (&lt;em&gt;circa&lt;/em&gt; 1996) was done in pure HTML, but now a site like MO can't be maintained without knowledge of a lot of the following things: CSS, Javascript, PHP, React/Angular/Vue, HTML 5, SQL/MongoDB/Firebase, Python, etc. Furthermore, the web development/design team needs to constantly stay up-to-date as security threats change and as browsers change, and as hardware and culture changes (making a site work well on small phones, tablets, etc.).&lt;/p&gt;&#xA;&lt;h1&gt;User participation would drop&lt;/h1&gt;&#xA;&lt;p&gt;Let's look at some of the other success (actually &amp;quot;lack of success&amp;quot;) stories for Q/A communities that are not part of the SE network.&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;a href=&quot;https://physicsoverflow.org/&quot; rel=&quot;nofollow noreferrer&quot;&gt;PhysicsOverflow&lt;/a&gt;. Notice the lack of usage, the archaic aesthetics, and the fact that the site looks completely messed up when you try to view it from a phone rather than a desktop. &lt;strong&gt;I say this with the utmost respect for the founders of the site&lt;/strong&gt;, knowing that starting one of the SE sites and getting it through Area51 was the hardest thing I've ever done in my life, and that I'd still probably prefer having gone through what I did versus trying to do everything on my own.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;a href=&quot;https://codidact.com/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Codidact&lt;/a&gt;.

Also be aware that the &lt;em&gt;&lt;strong&gt;vast majority&lt;/strong&gt;&lt;/em&gt; of the content there is simply copied and pasted from SE thanks to the creative commons license which allows them to do that. &lt;strong&gt;I say this again with the utmost admiration for what the Codidact founders have accomplished and for their vision&lt;/strong&gt;, which I support enthusiastically (I was in fact one of the early contributors to design elements that are still in place). Another problem with this community is that the main founders (Monica Cellio, ArtOfCode, Mithrandir, Mithical, luap/MEE) have in my opinion too much in common with the people currently running SE: 100% of my conversations with Monica about Codidact have been pleasant, but I have had mostly negative experiences with the other four.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;a href=&quot;https://topanswers.xyz/&quot; rel=&quot;nofollow noreferrer&quot;&gt;TopAnswers&lt;/a&gt;. This community is so unknown that I don't even know what to say here, other than the fact that I occasionally see this site mentioned as an alternative to SE, for example &lt;a href=&quot;https://codegolf.meta.stackexchange.com/a/18481/91582&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&lt;p&gt;&lt;a href=&quot;https://matsci.org/&quot; rel=&quot;nofollow noreferrer&quot;&gt;Materials Science Community Discourse&lt;/a&gt;.

However I can already see that the Materials Science Community Discourse website has a big banner saying that it's not supported on my browser (not a problem with SE). Also, it is a &amp;quot;traditional forum&amp;quot; with no voting, comments, or any of the other things that make SO/MO/SE the way it is.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;" OwnerUserId="66334" LastActivityDate="2023-06-11T19:56:19.280" CommentCount="6" ContentLicense="CC BY-SA 4.0" />

The short explanation is that the company has been making life difficult for moderators in rolling out changes to policy that binds how moderators can operate around dealing with AI-generated content, after many sites on the network set up their own policies (which is how it's supposed to work) banning it. The policy as announced privately to mods and what got announced publicly were slightly different, and the private one essentially tied all our hands.&lt;/p&gt;&#xA;&lt;p&gt;Stack Exchange the company released &lt;a href=&quot;https://meta.stackexchange.com/q/389928/226541&quot;&gt;internal data analytics&lt;/a&gt; that it felt showed that moderators were taking too much action on allegedly AI-content, leading to many false positives, but that analysis is by all accounts not that solid. The 35 responses at this post pull it apart in many ways. The biggest failing of the analysis is that it proceeds via a proxy count that by now demonstrably doesn't agree with what is seen on the ground by moderators, as the behaviour of users changed since the release of ChatGPT (this is the best guess among moderators, it's really unclear).&lt;/p&gt;&#xA;&lt;p&gt;One concerning matter that arose since the start of the strike was that it was discovered that the latest quarterly data dump of the whole network Q&amp;amp;A data (which is done under a Creative Commons license, and is a way to ensure the knowledge generated by users remains free) was missing. This was secretly turned off, and people were very much not happy about it. Thankfully, as a result of the resulting pressure, &lt;a href=&quot;https://meta.stackexchange.com/a/390200/226541&quot;&gt;the data dump was restarted and is now done&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;To add insult to injury, Stack Exchange had &lt;a href=&quot;https://meta.stackoverflow.com/q/425081/2113794&quot;&gt;announced it was going to roll out a tool&lt;/a&gt; for formatting code help on StackOverflow, the biggest site on the network. It turns out this was a &lt;a href=&quot;https://meta.stackoverflow.com/a/425208/2113794&quot;&gt;simplistic wrapper for a query to some generative large language model from OpenAI&lt;/a&gt; (the makers of ChatGPT), which a user extracted in ten minutes—complete with typos and instructions the bot happily ignores, as many users found out as they jailbroke the tool within half a day and made it do all kinds of fun things (&lt;a href=&quot;https://meta.stackoverflow.com/a/425207/2113794&quot;&gt;write a My Little Pony story&lt;/a&gt;, &lt;a href=&quot;https://meta.stackoverflow.com/a/425197/2113794&quot;&gt;answer the question outright&lt;/a&gt;, &lt;a href=&quot;https://meta.stackoverflow.com/a/425195/2113794&quot;&gt;play a game of chess&lt;/a&gt;, &lt;a href=&quot;https://meta.stackoverflow.com/a/425169/2113794&quot;&gt;invent questions out of whole cloth&lt;/a&gt;, &lt;a href=&quot;https://meta.stackoverflow.com/a/425184/2113794&quot;&gt;remove crucial parts of the question&lt;/a&gt;). Thankfully, Stack Exchange listened to the criticism, is turning off the experiment and going back to the drawing board. Though, to temper this relief, it's unlikely to go away forever. There's no hint that it will come to MathOverflow, since it's touted as a &amp;quot;code formatting assistant&amp;quot;, but the smell on the air is that the company wants to get more out of the AI pie as it's being passed from hand to hand.

The biggest move so far is that moderators elected representatives for negotiation and the negotiations have started. There is some movement: see the data dump point above, and another one that I'm not sure I can mention, but it's fairly minor. No one wants the network to fall over, but we might be in this phase for a while.&lt;/p&gt;&#xA;&lt;p&gt;In the meantime, please be patient with the decrease in moderation here on MO. Keep flagging content, because after the strike this can be returned to and cleaned up.

This policy will go into effect upon release, replacing the current private policy. More permanent standards will be established by a working group of moderators and users who are active in removing gen-AI content, in a private Stack Overflow for Teams instance. Information on how to be invited to the Team will be available when we move along a little further in the process.&lt;br /&gt;&#xA;The replacement policy will be based on &amp;quot;strong&amp;quot; and &amp;quot;weak&amp;quot; heuristics, with guidelines on removing based on which heuristics are present. Moderator judgement calls will still be required. These standards will be open to revision as technology changes and data is gathered on identifying AI-generated content.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Demand:&lt;/strong&gt; The private policy on GPT content that was issued to moderators must be revealed publicly.&lt;br /&gt;&#xA;&lt;strong&gt;Progress:&lt;/strong&gt; Stack has agreed to release it publicly on Meta. However, it will be released with a disclaimer (as-yet unwritten) stating that they do not plan on releasing all moderator policy guidance publicly, but are doing so in this case. This disclaimer will have to be approved by reps before it's posted. This will be released after the new interim policy goes into effect.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Demand:&lt;/strong&gt; The data dumps must be re-enabled, and SEDE and API access guaranteed.&lt;br /&gt;&#xA;&lt;strong&gt;Progress:&lt;/strong&gt; We have reached the agreement below. This commitment will be announced publicly by Stack Exchange, Inc. (I don't know exactly when).&lt;br /&gt;&#xA;&lt;strong&gt;Agreement:&lt;/strong&gt; Stack Exchange, Inc. commits to: Continuing to operate the data dumps; continuing to provide Stack Exchange Data Explorer access; and continuing to provide API access. All of these will remain operational and free of charge for individual network users, for the foreseeable, long-term future.  For companies and organizations, other terms may apply.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Demand:&lt;/strong&gt; Stack Exchange, Inc. must communicate, gather feedback, and act on that feedback before making major policy or software changes to the public platform.&lt;br /&gt;&#xA;&lt;strong&gt;Progress:&lt;/strong&gt; The representatives from Stack Exchange, Inc. have indicated that they are willing to add a stipulation that binding policy changes (i.e. anything tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/moderator-agreement-policy&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;moderator-agreement-policy&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;moderator-agreement-policy&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-moderator-agreement-policy-tooltip-container&quot;&gt;moderator-agreement-policy&lt;/a&gt;) go through a mandatory seven-day review period by moderators.

While I disputed many of the examples that were brought, some examples were brought that did cross the line.

They are not willing to retract the policy change based on that alone.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Issue:&lt;/strong&gt; Moderators were not spoken to by CMs when their actions were in doubt.&lt;br /&gt;&#xA;&lt;strong&gt;Progress:&lt;/strong&gt; Stack has stated that their internal guidance was to almost never consult with moderators about actions taken, due to a belief that moderators want to moderate and are not interested in justifying their actions to staff. We have established that the vast majority of moderators would welcome any questions about their actions and be more than willing to explain - or, even better, to train CMs in how to figure out why those actions were taken. Stack Exchange Inc. will revise their internal guidance to reflect this.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Issue:&lt;/strong&gt; Stack Exchange, Inc. made inappropriate comments to the press.&lt;br /&gt;&#xA;&lt;strong&gt;Progress:&lt;/strong&gt; We are debating this issue and have not yet reached a conclusion. Stack is so far unwilling to agree to a blanket policy of &amp;quot;no comment&amp;quot; when asked for comment on anything involving moderators; we are considering what our options are here. Stack Exchange, Inc. would like to keep open the option of commenting on general moderator actions not taken by an individual; the representatives are pushing for Stack to refrain commenting even about groups of moderators. Stack has also indicated that they think it would be unfair for the company to be bound to not comment while individual moderators are free to comment, citing my own personal statements to the press. I've reminded them that they are a billion-dollar company, while we are a group of volunteers.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Issue:&lt;/strong&gt; There is no recourse if Stack Exchange, Inc. breaks the Moderator Agreement.&lt;br /&gt;&#xA;&lt;strong&gt;Progress:&lt;/strong&gt; Frankly, there's been no progress. It was floated that a group such as the Moderator Council should have the authority to rule that an action taken by Stack Exchange, Inc. broke the Agreement, and is so rendered null and void; however, the Mod Council is currently defunct and is unlikely to be revived.

Stack Exchange, Inc. will also commit to only speaking about moderation and mods in the most general of terms and not comment on specifics; this would, for instance, preclude comments stating that the reason that the mods were on strike is because of AI detector tools.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Issue&lt;/strong&gt;: There is no recourse if Stack Exchange, Inc. breaks the Moderator Agreement.&lt;br /&gt;&#xA;&lt;strong&gt;Result&lt;/strong&gt;: Stack Exchange, Inc. will commit to issuing an apology to Meta.SE and retracting any actions taken that were found to have broken the Agreement, as determined by a consensus of moderators.

Additional tooling for this process will be developed, and these numbers aren't quite finalized.&lt;br /&gt;&#xA;Both of these changes will be enshrined in the Mod Agreement and will be subejct to the standard feedback and review process for changing the Agreement.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Issue&lt;/strong&gt;: Stack Exchange, Inc. is still insisting on having binding, private guidance.&lt;br /&gt;&#xA;&lt;strong&gt;Result&lt;/strong&gt;: Stack Exchange, Inc. is apparently willing to commit to not having private binding guidance that would result in actions being taken on user accounts (such as mandating declining flags) without a public policy to back it up. This would allow for private binding policies that are only applicable in moderator spaces or do not otherwise impact non-moderator users.&lt;br /&gt;&#xA;The Team for determining heuristics for AI-generated content has now been set up.

But the part that essentially triggered the strike was the part after the cut: &lt;strong&gt;no action&lt;/strong&gt; could be taken by a moderator on content they judged to be AI-generated, unless the user volunteered the information &amp;quot;I used AI to make this&amp;quot; without prompting or coercion (or was silly enough to not cut out words like &amp;quot;Regenerate answer&amp;quot; that flagged it as ChatGPT output). To do so would have been to violate the moderator agreement that elected mods all sign. If a user had outright continued to lie and say they wrote it, even with the kind of stylistic flags that it was chatGPT (say), and the kind of non-human errors GPTs make, flags had to be ignored, and no action taken.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;The policy below was posted on the Mod Team on May 29, 2023 to update moderators as to changes in how the GPT policy should be enforced. A day later, a shortened version of this policy was published on MSE. We normally do not release enforcement guidelines publicly. In recognition of the confusion caused by the differences between the public and private guidance in this case, we are now publishing the private text of this policy in full. However, we reserve the right to continue in the future to withhold specific enforcement guidelines from being published publicly in cases where doing so would make the jobs of moderators more challenging, and open up new avenues for abuse.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;This is being released now so that it can be included in the public record. Since being published, this policy has been superseded, with the new policy available shortly.&lt;/strong&gt; The historical policy begins with the line below this one.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;May 29, 2023&lt;/p&gt;&#xA;&lt;p&gt;[...]&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Therefore, the only admissible evidence we can currently permit for GPT usage is self-admission by the author of the posts, freely given.&lt;/strong&gt; Please note that “freely given” is important here: please do not, under any circumstances, try to trick users into admitting GPT usage, lure them into saying it, or otherwise coerce a response. Even a user saying they have used GPT &lt;em&gt;in general&lt;/em&gt; may not count unless they specifically say they have used it &lt;em&gt;here&lt;/em&gt;, or for &lt;em&gt;this contribution&lt;/em&gt;.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;The public position the company held (after the above) can be read in this &lt;a href=&quot;https://meta.stackexchange.com/a/389583/226541&quot;&gt;massively downvoted post&lt;/a&gt;, where the &lt;a href=&quot;https://meta.stackexchange.com/questions/389582/what-is-the-network-policy-regarding-ai-generated-content/389583#comment1299185_389583&quot;&gt;top comment&lt;/a&gt; is&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;This post does not match the guidance given to moderators.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;The omitted part in the big quote above outlines the company's justification, but it is based on what many have observed is &lt;a href=&quot;https://meta.stackexchange.com/questions/389928/gpt-on-the-platform-data-actions-and-outcomes&quot;&gt;flawed data analysis&lt;/a&gt; using a metric not verified as fit-for-purposes.

(this was largely a problem on the big coding/tech sites, we here on MO didn't even get to the point of even having to think about this, or dealing with scores of users flagging posts based on AI-detection scores of posts they tested)&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;ol start=&quot;2&quot;&gt;&#xA;&lt;li&gt;The company has openly committed to continuing the &lt;a href=&quot;https://api.stackexchange.com/&quot;&gt;API&lt;/a&gt;, &lt;a href=&quot;https://data.stackexchange.com/&quot; rel=&quot;nofollow noreferrer&quot;&gt;SEDE&lt;/a&gt; and the regular &lt;a href=&quot;https://archive.org/details/stackexchange&quot; rel=&quot;nofollow noreferrer&quot;&gt;data dumps&lt;/a&gt;, in this post: &lt;a href=&quot;https://meta.stackexchange.com/q/391634/226541&quot;&gt;The company&amp;#39;s commitment to the data dumps, the API, and SEDE&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;&lt;strong&gt;The company is committed to the long-term (foreseeable future) survival of the data dumps, the API, and SEDE.&lt;/strong&gt; We will continue to maintain them, and assure that community members have free access to them for legitimate usages that support the community, broadly construed (including for study in classrooms, for instance).

I believe AI is fundamentally damaging in the long-term to society in many ways, some of which are:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;AI removes human connection from the equation of information sharing. Sharing ideas and information is a fundamental cohesive force in our society and sharing information has always been about two things: the information itself, and developing relationships with other people. AI removes the latter, and creates a world where information sharing is anonymous. Of course, Stackexchange's initial foray into AI isn't a complete replacement, but it is an augmentation that will significantly distort human interaction in a negative way and eventually lead to a greater degree of anonymity.&lt;/li&gt;&#xA;&lt;li&gt;AI on a greater societal level is poised to take over almost every sort of creative job, including professor. Previous technologies have never been so poised to take over so many creative jobs. Of course, it's unlikely that AI will be able to do mathematics research any time soon (though it may do so in the future), but as we all know, mathematics is primarily a service department for other sciences and soon that function will be eliminated.&lt;/li&gt;&#xA;&lt;li&gt;In the long term, AI taking away jobs such as math professor, artist, and writer, will cause a mass loss of purpose in life and thus a mass wave of depression and lack of direction for humanity. Jobs will be increasingly meaningless, existing merely to further developing more advanced AI systems. The original motivations of research were curiosity and improving the human condition, but we are reaching a tipping point where those values will be stripped from us.&lt;/li&gt;&#xA;&lt;li&gt;With great power comes great responsibility, as the saying goes. We hardly have the ability to handle basic power with responsibility (c.f. fossil fuels, the internet). AI is simply too powerful to be used with responsibility by humanity.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;In closing, as mathematicians, we have a special viewpoint about the world. We can envision complex systems and far-reaching consequences. And, if we look at such consequences, we must conclude that AI is not just about some minor improvements to search and answers on Stackexchange (the short-term), but about the long-term societal effects of making the world devoid of human connections because removing such connections is the most efficient optimum for big-tech companies to concentrate the wealth of the world into the hands of the few.&lt;/p&gt;&#xA;&lt;p&gt;Thus, I believe that Mathoverflow should take a stand against AI and do everything possible to remove Mathoverflow from the Stackexchange network. Of course, this might have some short-term pains, but it would send a serious message that society at large should be more wary of what is going on.&lt;/p&gt;&#xA;" OwnerUserId="1437" LastActivityDate="2023-07-30T22:54:31.607" Title="Should Mathoverflow take a stand against AI?"

MO should be a place that is welcoming to professional mathematicians, and this means that MO should not have an official stance on issues that will make MO less welcoming to professional mathematicians.&lt;/p&gt;&#xA;&lt;p&gt;It is not practical for MO to take a stand against AI in general or even for particular uses of AI even if we want to take that stand. MO has a search bar for searching for questions and answers, and all search engines use AI in one form of another. Even the process of doing basic research when searching for an answer uses AI since one will need to interact with a search engine outside MO. One can often use gradient ascent/descent in order to search for counterexamples or figure out constants (especially in linear algebra), and one can use simulated annealing and evolutionary computation to produce counterexamples to conjectures. On this site, we are also able to ask and answer questions directly about AI, and we are able to have discussions about AI too.&lt;/p&gt;&#xA;&lt;p&gt;When trying to mitigate the risks imposed by AI, one has to carefully consider which strategies one should employ. Taking a stand against AI is unlikely to be effective since AI will develop and progress regardless of whether we want it to or not. A stand against AI development will simply allow some groups to progress unimpeded while other groups will be stifled, and this effort will result in inequality and less AI safety. If one wants to slow down AI progress, then one should have worked on AI safety earlier, and one now needs to work harder on AI safety.  While we may not be able to stop or slow down the development of AI, we can certainly steer the development of AI into a safer or more friendly direction. The MO community can do things individually and collectively to improve AI safety. The individuals here can read about AI safety so they know what others think about the risks of AI. After reading about AI safety, we may be willing and able to perform mathematical research that will improve AI safety. The community here can ask and answer questions about AI safety. The community can have a high level discussion about AI safety.

(I.e., something similar to Stack Exchange or Codidact).&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;There are several advantages to being part of the network. (Probably most of them are more-or-less obvious.)&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://meta.mathoverflow.net/questions/tagged/mathoverflow-inc&quot;&gt;MathOverflow, Inc.&lt;/a&gt; would have to deal with all technical issues by itself. For comparison, at the moment the only thing related to MO which isn't hosted by SE is the archive of the old tea. It is down &lt;a href=&quot;https://meta.mathoverflow.net/q/4438&quot;&gt;at least since January 2020&lt;/a&gt; and in all that time we did not even get any response from the mods whether or not the archive is considered abandoned or whether they plan to revive this at some point. The redirect, i.e., the part which was setup by SE, still works - but it goes to a dead page. (And, as a consequence, the answer to the &lt;a href=&quot;https://meta.mathoverflow.net/q/1&quot;&gt;very first question here on meta&lt;/a&gt; is - at the moment - untrue.) I understand that the main site is much more important than an archive with various old discussions - so MO wouldn't simply go silent for several years - but still, I would consider this as a datapoint showing that it is difficult to manage various real-life commitments and devote the time to keeping a big website alive.&lt;/li&gt;&#xA;&lt;li&gt;As a part of a larger network, MO can rely on help of users from other sites. There are things where people without knowledge of research-level mathematics are certainly able to help, too.

Certainly the MO moderators try to do good job, but naturally - as any human being - &lt;a href=&quot;https://chat.stackexchange.com/transcript/19138/2021/3/25&quot;&gt;occasionally they might make a mistake&lt;/a&gt;. I'd expect that in such situations, help from some experience mods of other sites (in the same network - i.e., dealing with the same Q&amp;amp;A software) could be a very useful thing.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;" OwnerUserId="8250" LastEditorUserId="8250" LastEditDate="2023-08-04T09:24:40.563" LastActivityDate="2023-08-04T09:24:40.563" CommentCount="0" ContentLicense="CC BY-SA 4.0" />

[&lt;strong&gt;EDIT&lt;/strong&gt; this is &lt;a href=&quot;https://socvr.org/&quot; rel=&quot;nofollow noreferrer&quot;&gt;SOCVR&lt;/a&gt;, and it has now reopened for business]&lt;/p&gt;&#xA;&lt;p&gt;We don't particularly see these tools in use on MO, and to see why they are needed, here's some figures for comparison: MO has right now just over 100 unhandled flags (about 25-30 times the usual maximum, in steady state, which get resolved fairly quickly). Stack Overflow had over 18000 unhandled flags until just recently, when it is more around the steady state of O(100), I believe.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;Philippe, the SE Vice-President of Community Management, has &lt;a href=&quot;https://meta.stackexchange.com/questions/391847/moderation-strike-results-of-negotiations/391992#391992&quot;&gt;posted a public statement&lt;/a&gt; at the &lt;a href=&quot;https://meta.stackexchange.com/q/391847/226541&quot;&gt;negotiations outcome post&lt;/a&gt; on behalf of the company stating&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Both I and the company will use our best efforts to comply with both the letter and the spirit of the agreements reached during the negotiations and laid out here.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Moreover the &lt;a href=&quot;https://meta.stackexchange.com/questions/391990/interim-policy-on-ai-content-detection-reports&quot;&gt;new, interim, policy on AI-generated content detection/reporting&lt;/a&gt; has been posted.

  <row Id="5735" PostTypeId="2" ParentId="5732" CreationDate="2023-08-08T03:05:11.527" Score="6" Body="&lt;p&gt;There are clearly cases when the tag &lt;a href=&quot;https://mathoverflow.net/questions/tagged/open-problem&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;open-problem&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;open-problem&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-open-problem-tooltip-container&quot;&gt;open-problem&lt;/a&gt; has been used a perfectly acceptable way, for instance asking questions about open problems as a class of problems, or in meta-discussion about a specific open problem. I believe the intended off-topic use-case is to so tag questions that are basically famous open problems, or mild variations on them. If a user is putting in a decent amount of background work into their question, delineating it carefully, and being very tight and focused on what their question is intended to cover, then there is more leeway as to what is allowed. As a counter-example, I recall a question &lt;a href=&quot;https://mathoverflow.net/questions/31846/is-the-riemann-hypothesis-equivalent-to-a-pi-1-sentence&quot;&gt;Is the Riemann Hypothesis equivalent to a $\Pi_1$ sentence?&lt;/a&gt;, which is not tagged &lt;a href=&quot;https://mathoverflow.net/questions/tagged/open-problem&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;open-problem&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;open-problem&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-open-problem-tooltip-container&quot;&gt;open-problem&lt;/a&gt;, though it is about an open problem (the RH) but actually on a very specific question that in the end itself wasn't an open problem. Tagging the above question as an open problem might indicate that the &amp;quot;is it equivalent to a &lt;span class=&quot;math-container&quot;&gt;$\Pi_1$&lt;/span&gt; sentence?&amp;quot; question was open, when it was not.&lt;/p&gt;&#xA;&lt;p&gt;As discussed in the comments, there is a sense in which many, if not most questions on MO are open problems: unless someone is asking for something in the literature, it is probably a problem no one has thought about before, or if so, very few. I have a couple of questions that ultimately led to more than one paper being published by others, because what I was asking about just didn't exist before. But I wouldn't consider tagging such a question as &lt;a href=&quot;https://mathoverflow.net/questions/tagged/open-problem&quot; class=&quot;post-tag&quot; title=&quot;show questions tagged &amp;#39;open-problem&amp;#39;&quot; aria-label=&quot;show questions tagged &amp;#39;open-problem&amp;#39;&quot; rel=&quot;tag&quot; aria-labelledby=&quot;tag-open-problem-tooltip-container&quot;&gt;open-problem&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;The &lt;a href=&quot;https://mathoverflow.net/questions/447472/open-problem-log-n-factor-in-binomial-empirical-process&quot;&gt;example given by the OP&lt;/a&gt; is in some sense a reasonable example, and would have been even if not such a success story. It is a very narrow technical question that had a chance of being answered, or at least prompting people to think about it. As originally asked, the question didn't mention how the question had been presented as an open problem. What should be avoided is questions that it's clear have no hope of getting an answer either on MO or by people thinking hard about it and subsequently writing a paper answering the question (this has happened due to space constraints: you can't post a 20-page paper as an MO answer!).&lt;/p&gt;&#xA;&lt;p&gt;Above all, the point of MO is to get answers to specific questions. The original mental image of MO was of being able to ask one's colleague down the hall, or at morning/afternoon tea. Telling people about an interesting open problem and asking a specific technical question about it, to an expert on that area, or a related one is useful if you think you'll get some kind of helpful answer. Bugging a colleague with a difficult, well-known open problem they cannot really say anything about is not productive.&lt;/p&gt;&#xA;" OwnerUserId="4177" LastActivityDate="2023-08-08T03:05:11.527" CommentCount="3" ContentLicense="CC BY-SA 4.0" />

(Users who never posted anything won't be shown here - but I assume you're not looking for such users. After all, if we filter the list using reputation too, most users with non-negligible reputation should have at least one post.)&lt;/p&gt;&#xA;&lt;p&gt;One should keep in mind that many users had several accounts which were merged at some point. And that many user accounts have been deleted over the years.&lt;/p&gt;&#xA;&lt;p&gt;As &lt;a href=&quot;https://meta.mathoverflow.net/posts/comments/29209&quot;&gt;pointed out by David Roberts&lt;/a&gt;, the above queries sort the users by id rather than by CreationDate - the sorting is not exactly the same.

I cite MathOverflow whenever it is relevant, and this has been the case in numerous circumstances.&lt;/p&gt;&#xA;&lt;p&gt;I am truly thankful that it is easy and convenient to cite MathOverflow questions and answers. One need only click the &amp;quot;cite&amp;quot; button to get usable bibtex code for that post.&lt;/p&gt;&#xA;&lt;p&gt;However, the default bibtex code that is provided can be improved in several respects. The current format seems to be a hodgepodge of sorts implementing various compromises, but I think we can design a more robust default bibtex format.&lt;/p&gt;&#xA;&lt;p&gt;Let me explain what I would like to see. Currently, for example, if I click on &amp;quot;cite&amp;quot; on my post answering &lt;a href=&quot;https://mathoverflow.net/a/457828/1946&quot;&gt;Extensions of PA+&lt;span class=&quot;math-container&quot;&gt;$\neg$&lt;/span&gt;Con(PA) with large consistency strength&lt;/a&gt;, what I get is:&lt;/p&gt;&#xA;&lt;pre&gt;&#xA;@MISC {457828,&#xA;    TITLE = {Extensions of &lt;span class=&quot;math-container&quot;&gt;$PA+\neg Con(PA)$&lt;/span&gt; with large consistency strength},&#xA;    AUTHOR = {Joel David Hamkins (https://mathoverflow.net/users/1946/joel-david-hamkins)},&#xA;    HOWPUBLISHED = {MathOverflow},&#xA;    NOTE = {URL:https://mathoverflow.net/q/457828 (version: 2023-11-06)},&#xA;    EPRINT = {https://mathoverflow.net/q/457828},&#xA;    URL = {https://mathoverflow.net/q/457828}&#xA;}&#xA;&lt;/pre&gt;&#xA;&lt;p&gt;What I would like to get is something more like this:&lt;/p&gt;&#xA;&lt;pre&gt;&#xA;@MISC {MO457828,&#xA;    TITLE = {Extensions of &lt;span class=&quot;math-container&quot;&gt;$PA+\neg Con(PA)$&lt;/span&gt; with large consistency strength},&#xA;    AUTHOR = {Joel David Hamkins},&#xA;    authorid = {1946},&#xA;    authorurl = {https://mathoverflow.net/users/1946/joel-david-hamkins},&#xA;    HOWPUBLISHED = {MathOverflow answer},&#xA;    year = {2023},&#xA;    keywords = {lo.logic},&#xA;    URL = {https://mathoverflow.net/q/457828},&#xA;    urldate = {2023-11-06}&#xA;}&#xA;&lt;/pre&gt;&#xA;&lt;p&gt;[&lt;strong&gt;Note:&lt;/strong&gt; I updated the date format to YYYY-MM-DD per Willie's answer.]&lt;/p&gt;&#xA;&lt;p&gt;To explain the requested features:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The year field should be set to the year of the post. This is an important basic bibtex field, which should definitely be set, but is not set in the default behavior.&lt;/li&gt;&#xA;&lt;li&gt;The howpublished field should differentiate between &amp;quot;MathOverflow question&amp;quot; and &amp;quot;MathOverflow answer&amp;quot;. This is an important distinction that I always observe in my own citations, and I think it should become standard.&lt;/li&gt;&#xA;&lt;li&gt;The bibentry id can be improved by prefacing MO to the id number. This would follow MR practice. I expect that most people will make further edits to the id to follow their own personal naming practice.&lt;/li&gt;&#xA;&lt;li&gt;The keywords fields can be set to a comma-separated list of the tags on the main post. This field is used currently by many bibtex styles, as well as by various web apps, mainly for the purpose of sorting bibliographies by topic.&lt;/li&gt;&#xA;&lt;li&gt;The url should be in the url field only. Why are we setting the url in three different fields? When I use the bib data as-is, the url shows up three times in my bibliography. This weird handling of the url seems to have arisen as a compromise trying to accommodate various outdated bibtex usage practices (some predating the common use of urls), but is incompatible with current best practice. I think we should instead settle upon a robust sensible bibtex format, which will work going forward with current and new bibtex formats that people might design. Specifically, for the treatment of urls, I believe the most sensible format will be to use the url and the urldate fields.&lt;/li&gt;&#xA;&lt;li&gt;the urldate should be set to the date of the post (or the date of access?). This is exactly what this field is for.&lt;/li&gt;&#xA;&lt;li&gt;The author field should be used for the author name only, that is, the username. The other author information such as the id number and the url can be placed into other sensible author fields as I indicate. This will allow for easy edits of the bibtex entry, if someone should want to place that information into the author field, such as in the case of an anonymous author, but will also work well for what in my experience has been the main use case, where one is citing an author by their actual name. The authorurl field will enable bibstyles easily to set the author name itself as a hyperlink.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;strong&gt;Question.&lt;/strong&gt; What other requested behavior of the cite function might there be?&lt;/p&gt;&#xA;" OwnerUserId="1946" LastEditorUserId="8250" LastEditDate="2023-12-14T16:48:57.283" LastActivityDate="2023-12-28T22:07:32.557" Title="Request for improvements to the citation bibtex format" Tags="|feature-request|citations|bibtex|" AnswerCount="3" CommentCount="16" ContentLicense="CC BY-SA 4.0" />

Others do not. If I am citing a post given by &amp;quot;PseudoNeo&amp;quot;, having just that name as the author is not reasonable and I wouldn't be surprised to find an editor who would complain about that sort of citation appearing in the bibliography (on the other hand, footnotes get a much broader pass). You say that in the case of an anonymous author this can be a reasonable thing after all, but how should the software recognise when a name is reasonable or not?&lt;/p&gt;&#xA;&lt;p&gt;Secondly, the name of the reference is something that every person has their own convention. If MathSciNet exports in a way that doesn't match your convention, and I'm assuming that you're using that so much more than you're using the cite button on MathOverflow, then I don't see why MathOveflow should conform to one user's style or another. Having the post ID there is fine, with perhaps the change be &amp;quot;MO&amp;quot; or something.&lt;/p&gt;&#xA;&lt;p&gt;Having said that, please remember that the cite feature is something that exists on multiple websites across the network, so making changes is something that while possible, will need to be in a modular enough way so that it doesn't change citations on Physics.SE or CS.SE or Math.SE to look like they came out of MathOverflow.&lt;/p&gt;&#xA;&lt;p&gt;Finally, arXiv exports the eprint field, and presumably that one is used at least as much as the MathOverflow cite feature. And not everyone use biblatex either.&lt;/p&gt;&#xA;&lt;p&gt;So, while we can probably take some of your requests and make them happen, and I agree that adding question/answer to the citation is a good distinction, I think that making edits for something to match your own personal style is something that we all quite literally need to contend with, and that's okay.&lt;/p&gt;&#xA;" OwnerUserId="7206" LastActivityDate="2023-11-20T10:39:20.203" CommentCount="7" ContentLicense="CC BY-SA 4.0" />

Regardless of what you think belong in that field, the data as currently presented breaks every attempt to sort/alphabetize authors correctly (in large part due to the parenthetical url).&lt;/p&gt;&#xA;&lt;p&gt;As online names are not necessary real names, nor do they conform to standard western first/last name preferences, I would request that &lt;em&gt;no matter what data is placed in the field&lt;/em&gt;, please at least make it so that the &lt;code&gt;author&lt;/code&gt; field includes an extra pair of braces.

BibTeX and BibLaTeX by design do not place any limits to what fields can be used in the &lt;code&gt;.bib&lt;/code&gt; file. The system is extremely extensible in that one can create one's own bibliography style to include any field one wants. (See, e.g., how to do it for &lt;a href=&quot;https://tex.stackexchange.com/questions/261649/add-custom-field-to-bibtex-entry-and-print-it&quot;&gt;bibtex&lt;/a&gt;; biblatex is considerably easier.) Fields that are unused by the bibliography styles are silently ignored.&lt;/p&gt;&#xA;&lt;p&gt;&lt;em&gt;Proposing a way to generate &lt;code&gt;bibtex&lt;/code&gt; entry, especially when it comes to &amp;quot;new fields&amp;quot; that are ignored by, say, &lt;code&gt;plain.bst&lt;/code&gt;, is therefore incomplete without specifying what the intended bibtex/biblatex styles it is targeting.&lt;/em&gt;&lt;br /&gt;&#xA;This is exacerbated by the fact that while there is general agreement for printed matter what are the useful fields to include, for online matter there are rather divergent implementations between various commonly used bibtex styles and biblatex configurations. The current output is a sort of common denominator / compromise between the various styles.&#xA;Unfortunately, I am quite pessimistic (especially since we are mathematicians) on the prospect of this community settling on one single bibtex style to use.&lt;/p&gt;&#xA;&lt;h3&gt;Defining a new document type?&lt;/h3&gt;&#xA;&lt;p&gt;One option is to explore is to maybe embrace &lt;code&gt;biblatex&lt;/code&gt;; this makes it relatively easy to &lt;a href=&quot;https://tex.stackexchange.com/questions/175776/how-can-i-create-entirely-new-data-types-with-biblatex-biber&quot;&gt;define new document types&lt;/a&gt;.

This is a big research area, known by the name &amp;quot;Models of PA&amp;quot;, with hundreds or perhaps thousands of published articles. There are several books with the phrase &amp;quot;Models of Peano arithmetic&amp;quot; in the title, there is the MOPA seminar in New York (MOPA = Models of PA), and many researchers describe their subject as &amp;quot;Models of PA&amp;quot;.&lt;/p&gt;&#xA;&lt;p&gt;There are many dozens of questions on MO, perhaps hundreds, about models of PA. We used to have the tag models-of-pa, which I often used and which was just perfect for this research area.&lt;/p&gt;&#xA;&lt;p&gt;We have the tag theories-of-arithmetic, to be sure, which is a fine subject, but for many questions, focused on the model theory of PA, that tag is unnatural, since these questions are about the models, not the theories. The tag models-of-pa was folded into theories-of-arithmetic, but in many cases this seems off to me. I think many questions currently tagged with theories-of-arithmetic, perhaps even most of them, would be better tagged with models-of-pa.&lt;/p&gt;&#xA;&lt;p&gt;To be sure, questions in models of PA often turn into questions about weaker theories, as one optimizes the results, and these further questions would usually be thought of under the description &amp;quot;weak arithmetic&amp;quot;. For example, there is the big conference series Weak Arithmetic Days, between Paris and NYC, which is all about models of PA and weaker arithmetic theories. I would support a weak-arithmetic tag for posts in this area, although probably theories-of-arithmetic is already suitable.&lt;/p&gt;&#xA;&lt;p&gt;I recognize that &amp;quot;pa&amp;quot; is perhaps not descriptive enough in a tag, but in this case I would recommend that models-of-pa be a tag synonym for models-of-peano-arithmetic, so that when users type models-of-pa it turns into models-of-peano-arithmetic on the site.&lt;/p&gt;&#xA;&lt;p&gt;As a compromise, since I recognize that MO has many logic users who are focused on weaker arithmetics such as IDelta_0 etc., we could have models-of-arithmetic. But in truth, I think those users are more focused on the theories than the models, and so perhaps they would prefer theories-of-arithmetic anyway.&lt;/p&gt;&#xA;&lt;p&gt;I would be less happy with a tag peano-arithmetic, since the name of the subject is &amp;quot;Models of PA&amp;quot;, but having that tag would be better than having to use theories-of-arithmetic.&lt;/p&gt;&#xA;&lt;p&gt;I think we need two tags:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;p&gt;models-of-pa, synonym for models-of-peano-arithmetic, for questions in the research area known as models of PA.

There are several problems with periodic exceptions:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;Future users are getting mixed signals: one buried in the help page that new users probably won't see, and one represented by a highly upvoted question (that experienced users know is off-topic but allowed anyway).&lt;/li&gt;&#xA;&lt;li&gt;Exceptions are not applied uniformly, and can appear to be the whims of moderators.&lt;/li&gt;&#xA;&lt;li&gt;Big list questions that garner many answers linger on the main page, pushing other questions down and making it hard for research mathematicians to get actual help on their research, if they have the misfortune of asking during a time when such a question is active.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;As Tim pointed out, a question regarding the &amp;quot;most important results of the year&amp;quot; was asked on December 22, was quickly closed, and then prompted this meta thread on the same day. Then, on December 27, a different user asked essentially the same question, and got (as of this writing) 55 upvotes and 6 downvotes. Talk about a whim! I wonder how the person who asked the Dec 22 question feels. The user who asked the Dec 27 question, Bogdan Grechuk, said in the comments that he didn't check meta or the previous closed question, and just asked because he enjoys this kind of topic (and does not seem to care if the question is appropriate or not). A classic example of (1) above.&lt;/p&gt;&#xA;&lt;p&gt;When relatively new users ask questions that are off-topic, experienced users often write comments or include text in answers that helps the user (and future readers) realize why their question is off-topic, sometimes while also answering. Like, if a question asks for career advice, an answer might begin &amp;quot;Well, this question is really more appropriate for academia.SE, but while it's here on MO, I'll share my own experience...&amp;quot; We see the same thing all the time for questions that are more appropriate for MSE but still get a quick answer on MO.&lt;/p&gt;&#xA;&lt;p&gt;In that spirit, I answered the Dec 27 question, including the following text:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;I believe this question should be closed, and that we should not have a holiday tradition of asking &amp;quot;what are the biggest results of the past year&amp;quot; because such a question is clearly &amp;quot;primarily opinion based&amp;quot; and is not about research mathematics. Voting patterns will show only which subfields of math are over-represented on mathoverflow, and that's a poor proxy for importance of the result mentioned.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I also gave the OP a link to the Quanta magazine article that lists the breakthrough results of 2023, and I mentioned a result in my area (that the telescope conjecture is false) that didn't make the Quanta list. Despite the entire thread being &amp;quot;primarily opinion based&amp;quot;, various users panned my answer for &amp;quot;editorializing&amp;quot; or &amp;quot;muddying the waters.&amp;quot; Eventually, a moderator, Stefan Kohl (who I respect a lot, by the way) edited my answer to take away the part that commented on why the question is off-topic for MO, pointing out that such discussion belongs on meta instead of main. Again, this feels like we're making exceptions for one thing, but not for another. As of this writing, my answer has 21 upvotes and 19 downvotes, and serves as an example of why &amp;quot;primarily opinion based&amp;quot; questions are not appropriate for mathoverflow. Anyway, I rolled back Stefan's edit because I'm not ok with having an answer of mine to a clearly off-topic question without a disclaimer, contributing to the problem where future users will see the highly upvoted question and think they should ask the same thing for 2024. If my answer remains, I think it's important that it contain a disclaimer that the question is not appropriate. If the moderators feel strongly that such a disclaimer should not appear in an answer, then they can delete my answer entirely.&lt;/p&gt;&#xA;&lt;p&gt;I do think the community should settle once and for all the controversy of whether or not these kinds of questions are allowed, to avoid this recurring problem. The situation feels analogous to populist political movements, so I think we need to hear from the moderators, who were elected to think about what's best long-term. I support closing the question for each of the previous years, so that users will know they are off-topic and will not ask again in future years. Or, if the moderators think these questions should be allowed, then having them asked on a predetermined date each year by some special account, with text that makes it clear that this is a holiday exception to the rules. Otherwise, I predict we'll see this kind of question asked every year, and it'll be a race among new users who want a highly upvoted question, to ask the question before anyone else does.&lt;/p&gt;&#xA;&lt;p&gt;EDIT: This debate seems to elicit strong feelings in people. After posting this answer here on meta, a user kept vandalizing my original post on the &amp;quot;breakthrough results&amp;quot; question, so much so that I had to ask the moderators to stop that user. So, for the moment, that answer is locked to prevent tampering, but I strongly suspect that this group of angry users who want to silence opposition to their position will go back and vandalize my answer more when the lock expires. I thought I'd put an update here on meta to explain the situation. Also, I wanted to add a few examples of other places where someone commented in an answer about the appropriateness of the question:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/a/126065/11540&quot;&gt;https://mathoverflow.net/a/126065/11540&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/a/372901/11540&quot;&gt;https://mathoverflow.net/a/372901/11540&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/a/312328/11540&quot;&gt;https://mathoverflow.net/a/312328/11540&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/a/454778/11540&quot;&gt;https://mathoverflow.net/a/454778/11540&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://mathoverflow.net/a/56229/11540&quot;&gt;https://mathoverflow.net/a/56229/11540&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;I am sure there are many more examples, but I don't want to spend tons of time cataloging them all.&lt;/p&gt;&#xA;&lt;p&gt;EDIT 2: In the end, the moderators decided to delete my answer, then repost just the part about the Telescope Conjecture. So, it seems the decision is to ignore the rules on the help page when it comes to asking a clearly off-topic question, but then strictly enforce an unwritten rule that says not to comment on the appropriateness of a question when answering it. I suppose that if the moderators want to avoid a double-standard, they should also edit the five answers I linked above that commented on the appropriateness of their respective questions. The deletion of my answer also removed the following text, which is yet another reason why this &amp;quot;breakthrough&amp;quot; question should have never been asked, since it already has a whole article of Quanta devoted to answering the exact same thing:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;Furthermore, there is already a yearly article &amp;quot;The Biggest Discoveries of the year&amp;quot; in Quanta Magazine. Here is the one for 2023. It already mentions the Ramsey theory result that is currently the top answer here. It also mentions results in combinatorics, number theory, aperiodic tiling, and physics (namely, the math governing boundaries of black holes).&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Overall, I am displeased with how this was handled. I think it contributes to the problem of lack of clarity in what is considered on vs off-topic, and to the perception that the moderators act according to whims rather than according to the written rules of the site.&lt;/p&gt;&#xA;&lt;p&gt;EDIT 3: &lt;a href=&quot;https://mathoverflow.net/a/111876/11540&quot;&gt;Here&lt;/a&gt; is a great example of a MathOverflow answer that consists of explaining why the question was a bad question. Like my answer, it received both upvotes and downvotes (as of this writing, 10 upvotes and 8 downvotes). Unlike my answer, it was not subjected to harassment or snarky comments, and was not deleted by the moderators. Oh, well. I guess it's not news to anyone that MO doesn't maintain consistency regarding the rules, or else the &amp;quot;breakthrough&amp;quot; question would have been closed as violating the rules of the FAQ that I linked to above.&lt;/p&gt;&#xA;" OwnerUserId="11540" LastEditorUserId="11540" LastEditDate="2024-02-23T00:17:06.897" LastActivityDate="2024-02-23T00:17:06.897" CommentCount="18" ContentLicense="CC BY-SA 4.0" />

I think this concern is distinct from that about background information. When I see &amp;quot;Make sure that the question includes the necessary background&amp;quot;, what comes to my mind is describing the motivation and/or importance and/or context and/or pre-history of the question -- all that quite apart from the specific request to define all the terms and symbols used. I would see presenting such background information as a good thing, but usually not necessary in order to understand the essence of the question.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;Rationale for Item 3:&lt;/strong&gt; Asking multiple questions in one post will usually make the post less attractive to answerers, and then the asker would not benefit either. Moreover, &lt;a href=&quot;https://mathoverflow.net/help/how-to-answer&quot;&gt;existing guidelines&lt;/a&gt; say &amp;quot;avoid trying to answer questions which [...] request answers to multiple questions&amp;quot;.)&lt;/p&gt;&#xA;&lt;p&gt;Of course, the short list of guidelines for writing better questions should be short.

For example, many Facebook users deleted their profiles after the 2020 presidential election in the USA, and this also deleted their data from Facebook’s servers. However, on MathOverflow, deleting your profile leaves most of your data on the site. Your name will be removed and your profile renamed to something like user12345, but your questions, answers, and comments remain. Also, comments of others like &amp;quot;As David White wrote above, ...&amp;quot; remain unchanged, so it’s easy to realize that user12345 was David White, and to also &lt;a href=&quot;https://math.meta.stackexchange.com/questions/30273/is-it-possible-to-know-the-questions-and-answers-by-a-no-longer-user&quot;&gt;gather all contributions&lt;/a&gt; &lt;a href=&quot;https://meta.mathoverflow.net/a/3749/11540&quot;&gt;by that user&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;It is easy to imagine hypothetical scenarios (hopefully all extremely unlikely) that would cause a user to no longer want to be publicly affiliated with MathOverflow, e.g.,&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;The company decides to monetize it, so all users have to pay to use the site (this happened with CouchSurfing, for example).&lt;/li&gt;&#xA;&lt;li&gt;Something terrible happens with the company, so that you as a professional mathematician no longer want to be associated with them (something like this happened with DataCamp).&lt;/li&gt;&#xA;&lt;li&gt;The nature of the community changes radically, e.g., MathOverflow becomes Chegg and everyone comes here to get their homework answered, and again you don’t want to be associated because you don’t agree with the shift.&lt;/li&gt;&#xA;&lt;li&gt;The community changes and becomes known as a nasty place, perhaps one that contributes to the problem of the underrepresentation of women and minorities in mathematics.&lt;/li&gt;&#xA;&lt;li&gt;The political landscape in your country changes, and now you're worried about government prosecution for an opinion you once shared on the site.&lt;/li&gt;&#xA;&lt;li&gt;etc.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;I know it’s not popular to think about these kinds of worst-case scenarios, but I do think it’s valuable, especially because the help documents essentially say &amp;quot;any data you put here belongs to you but is licensed to the SE company forever&amp;quot; and tells you that deleting your profile doesn’t remove your data. While we all hope the community agreements and standards hold forever, and make the scenarios above impossible, it’s a sad fact of life that throughout history companies have broken promises to users, or changed in fundamental ways, which would necessitate this kind of exit.&lt;/p&gt;&#xA;&lt;p&gt;Even if you think none of those scenarios is likely, it’s worth thinking about what will happen to the data you’ve entered on the site, after you die.&lt;/p&gt;&#xA;&lt;p&gt;If user X wanted to scrub their presence from the site, before deleting their profile, that user could delete every question, answer, and comment they’ve ever posted. Of course, high rep users could still see the deleted questions and answers, but user X could also edit the text down to just a single character, to make it harder to uncover what was there. However, &lt;a href=&quot;https://meta.mathoverflow.net/questions/4526/to-moderators-is-my-account-deleted&quot;&gt;this kind of thing was once called &amp;quot;self vandalism&amp;quot; by a MathOverflow moderator&lt;/a&gt;, making me wonder about the question of who really owns contributions. Furthermore, this procedure would take a long time, and it strikes me that moderators have the power to fully delete content (I think it's called &amp;quot;destroying an account&amp;quot;), e.g. as happens with spam answers. Hence my questions:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;(1) How could one automate a complete or maximally-possible removal of one’s data from MathOverflow?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;(2) Is there interest in the community in having the ability to ask moderators to destroy our accounts, for the reasons explained above.&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;Please don't answer along the lines &amp;quot;According to the terms of service of the site, the following will happen when a user deletes their account...&amp;quot; or &amp;quot;Hey, every user agreed to the terms of service, so it's wrong that they would want to remove their contributions years later.&amp;quot; It's worth pointing out that the procedures around deletion and contributions &lt;a href=&quot;https://meta.mathoverflow.net/a/2844/11540&quot;&gt;have changed&lt;/a&gt; since many users started using the site, and several of the hypothetical scenarios above are changes that a user might not have been able to forecast when they started using the site 10+ years ago. Rather than answers like &amp;quot;this cannot be done; we own all user contributions forever&amp;quot; I am interested in actual solutions, or in understanding if there is interest in the community in having the ability to request that moderators destroy an account at the request of the user, which would have the effect of deleting all contributions. I would also like to say that I myself am not currently considering deleting anything from mathoverflow, but events over the past year (e.g., the moderator strike, parent company changing policies without input from users, etc.) led me to wonder about how long-time users can exit the community, based on hypothetical scenarios.&lt;/p&gt;&#xA;" OwnerUserId="11540" LastEditorUserId="11540" LastEditDate="2024-01-05T20:53:18.740" LastActivityDate="2024-01-05T20:53:18.740" Title="Procedure for requesting a complete removal from MathOverflow" Tags="|discussion|feature-request|" AnswerCount="1" CommentCount="28" ContentLicense="CC BY-SA 4.0" />

So this is not saying that only half of &lt;em&gt;all&lt;/em&gt; questions had an answer at the time.)&lt;/p&gt;&#xA;&lt;p&gt;This is how the graph with the percentage looks at the moment:&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/xUv3z.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/xUv3z.png&quot; alt=&quot;Graph&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;If we exclude closed questions from our stats, the graphs do not look very differently: &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1813561/number-of-questions-with-at-least-one-answer-per-month-excluding-closed-quest#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;numbers&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1813562/percentage-of-questions-with-at-least-one-answer-per-month-excluding-closed-q#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;percentages&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;How fast they get answered?&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;If you look at the time until the first answer, the majority of questions gets an answer &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1223814/number-of-days-until-the-first-answer#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;on the same day as the question is posted&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1225002/delay-of-answer-after-the-question#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;the majority of answers is posted on the same day as the question&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;In connection with this, one might be interested to see questions &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1475569/longest-time-until-the-first-answer&quot; rel=&quot;nofollow noreferrer&quot;&gt;the longest&lt;/a&gt; and &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1475570/shortest-time-until-the-first-answer&quot; rel=&quot;nofollow noreferrer&quot;&gt;the shortest&lt;/a&gt; time until the first answer.&#xA;For the shortest time, it make sense to &lt;a href=&quot;https://data.stackexchange.com/mathoverflow/query/1475574/shortest-time-until-the-first-answer-excluding-the-answers-posted-simultaneousl&quot; rel=&quot;nofollow noreferrer&quot;&gt;exclude the answers posted simultaneously with the question&lt;/a&gt; (and the answers which are older than the question - such answers are probably consequence of &lt;a href=&quot;https://meta.mathoverflow.net/tags/merging/info&quot;&gt;merging&lt;/a&gt; two questions).

But &lt;strong&gt;not the deleted ones&lt;/strong&gt; - so you won't find here rejected migrations, with the exception with the ones which are still not deleted.&lt;/p&gt;&#xA;&lt;p&gt;See also: &lt;a href=&quot;https://meta.stackexchange.com/q/280576&quot;&gt;Migration notes in schema at Data.SE&lt;/a&gt; and &lt;a href=&quot;https://meta.stackexchange.com/q/296190&quot;&gt;How can I track for rejected migrations in the SEDE?&lt;/a&gt; For migrations we should look in the PostHistory table, which is described in detail here: &lt;a href=&quot;https://meta.stackexchange.com/q/2677&quot;&gt;Database schema documentation for the public data dump and SEDE&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;Keep in mind that SEDE is only updated once a week.&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;For example: &lt;a href=&quot;https://data.stackexchange.com/math/query/1813980&quot; rel=&quot;nofollow noreferrer&quot;&gt;this query&lt;/a&gt; and a similar query &lt;a href=&quot;https://data.stackexchange.com/math/query/1813982&quot; rel=&quot;nofollow noreferrer&quot;&gt;with some information about the post&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;The above queries show migrations from all sites to Mathematics - but the Comment field in the PostHistory table could help to restrict this specifically to MO: &lt;a href=&quot;https://data.stackexchange.com/math/query/1813983&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://data.stackexchange.com/math/query/1813983&lt;/a&gt;. (Unlike the previous two queries, in this case I list only migrated questions, not the answers migrated together with the questions.)&#xA;And from that you can get various stats - e.g. numbers per month, percentage of questions with at least one answer, questions with accepted answer etc.&lt;/p&gt;&#xA;&lt;p&gt;For example, &lt;a href=&quot;https://data.stackexchange.com/math/query/1813987/stats-about-migrations-from-mo-to-mse-all-at-least-one-answer-accepted-answer#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;this query&lt;/a&gt; shows: number of all migrated questions, number of questions with at least one answer, number of questions with an accepted answer (per year). Naturally, looking at accepted answers can be somewhat misleading - many users do not bother accepting an answer. (And one should keep in mind that in some cases one or more answers was posted already on MO - before the migration.)&lt;/p&gt;&#xA;&lt;p&gt;In the graphs below I have excluded 2024 - we're in January, the stats for such short period are not comparable with previous years. (But the queries can be used for any period)&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/U0Ou4.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/U0Ou4.png&quot; alt=&quot;Graph&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;And &lt;a href=&quot;https://data.stackexchange.com/math/query/1814069/stats-about-migrations-from-mo-to-mse-all-at-least-one-answer-accepted-answer#graph&quot; rel=&quot;nofollow noreferrer&quot;&gt;this query&lt;/a&gt; shows percentages rather than absolute numbers.&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&quot;https://i.stack.imgur.com/WE2Y1.png&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;img src=&quot;https://i.stack.imgur.com/WE2Y1.png&quot; alt=&quot;Graph&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;Another outcome, which can IMO be considered a &lt;em&gt;success&lt;/em&gt; is when the migrated question was closed as a duplicated.

I think the &lt;span class=&quot;math-container&quot;&gt;$X$&lt;/span&gt; there is quite elementary, as is mine, but the &lt;span class=&quot;math-container&quot;&gt;$X$&lt;/span&gt; there almost certainly has better properties/structure.&lt;/p&gt;&#xA;&lt;hr /&gt;&#xA;&lt;p&gt;This isn't my written-out question, just a brief description of my &lt;span class=&quot;math-container&quot;&gt;$X$&lt;/span&gt;.&lt;/p&gt;&#xA;&lt;p&gt;My &lt;span class=&quot;math-container&quot;&gt;$X$&lt;/span&gt; is the following: where &lt;span class=&quot;math-container&quot;&gt;$S:=\operatorname{Seq}_0(\mathbb{N}_0)$&lt;/span&gt; is the set of eventually-zero &lt;span class=&quot;math-container&quot;&gt;$\mathbb{N}_0$&lt;/span&gt;-valued sequences, using prime decomposition of &lt;span class=&quot;math-container&quot;&gt;$n\in\mathbb{N}$&lt;/span&gt;, we have a bijection:&lt;/p&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$\pi:\mathbb{N}\to S,$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;p&gt;e.g. &lt;span class=&quot;math-container&quot;&gt;$\pi(1)=(0,0,\dots,)$&lt;/span&gt;, &lt;span class=&quot;math-container&quot;&gt;$\pi(18)=(1,2,0,0,0,\dots)$&lt;/span&gt;, etc.&lt;/p&gt;&#xA;&lt;p&gt;Where &lt;span class=&quot;math-container&quot;&gt;$r_i$&lt;/span&gt; is the &lt;span class=&quot;math-container&quot;&gt;$i$&lt;/span&gt;th component of &lt;span class=&quot;math-container&quot;&gt;$r\in S$&lt;/span&gt;, we have operations on &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt;:&lt;/p&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$[s\boxed{+}r]_i=s_i+r_i\qquad(r,s\in S),$$&lt;/span&gt;&#xA;&lt;span class=&quot;math-container&quot;&gt;$$[s\boxed{\times}r]_i=s_i\times r_i\qquad (r,s\in S).$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;p&gt;The bijection allows us to transport addition &lt;span class=&quot;math-container&quot;&gt;$+$&lt;/span&gt; and multiplication &lt;span class=&quot;math-container&quot;&gt;$\times$&lt;/span&gt; on &lt;span class=&quot;math-container&quot;&gt;$\mathbb{N}$&lt;/span&gt; to operations &lt;span class=&quot;math-container&quot;&gt;$\boxed{\star}$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\boxed{+}$&lt;/span&gt; on &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt;, and the addition &lt;span class=&quot;math-container&quot;&gt;$\boxed{+}$&lt;/span&gt; and multiplication &lt;span class=&quot;math-container&quot;&gt;$\boxed{\times}$&lt;/span&gt; on &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt; to operations &lt;span class=&quot;math-container&quot;&gt;$\times$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$\diamond$&lt;/span&gt; on &lt;span class=&quot;math-container&quot;&gt;$\mathbb{N}$&lt;/span&gt;.&lt;/p&gt;&#xA;&lt;p&gt;We have, of course:&lt;/p&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$m\times n=\pi^{-1}(\pi(m)\boxed{+}\pi(n))\qquad(m,n\in\mathbb{N}),$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;p&gt;We get a strange operation on &lt;span class=&quot;math-container&quot;&gt;$\mathbb{N}$&lt;/span&gt;:&lt;/p&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$m\diamond n=\pi^{-1}(\pi(m)\boxed{\times}\pi(n))\qquad (m,n\in\mathbb{N}),$$&lt;/span&gt;&#xA;as well as a strange operation on &lt;span class=&quot;math-container&quot;&gt;$S$&lt;/span&gt;:&lt;/p&gt;&#xA;&lt;p&gt;&lt;span class=&quot;math-container&quot;&gt;$$r\boxed{\star}s=\pi(\pi^{-1}(r)+\pi^{-1}(s))\qquad (r,s\in S).$$&lt;/span&gt;&lt;/p&gt;&#xA;&lt;p&gt;We have &lt;em&gt;some&lt;/em&gt; structure therefore on &lt;span class=&quot;math-container&quot;&gt;$(\mathbb{N},\times,\diamond)$&lt;/span&gt; and &lt;span class=&quot;math-container&quot;&gt;$(S,\boxed{\star},\boxed{+})$&lt;/span&gt;.&lt;/p&gt;&#xA;" OwnerUserId="35482" LastEditorUserId="35482" LastEditDate="2024-01-17T09:59:37.353" LastActivityDate="2024-01-17T09:59:37.353" Title="Are &quot;has this been studied before&quot; questions on topic?"

When does each day start?&lt;/a&gt; In short, it uses UTC - so depending on your timezone, it is possible that two of your actions fall into two different days in the database even if in your local time they were on the same day.&lt;/p&gt;&#xA;&lt;hr&gt;&#xA;&lt;p&gt;If you see that there are many days (hours) next to your name, you can view this information positively (since you see that you are often here and you know that your activities here are useful).&#xA;On the other hand, some people might see this as a negative sign - that they spend too much here instead of other stuff that they are supposed to be doing.

Every bit of time and effort y'all contribute to the site gives you access to more privileges you can use to help in this effort, all of which produce a cumulative effect that makes a big difference in ensuring Stack Exchange sites remain a valuable source of high-quality content on the web.&lt;/p&gt;&#xA;&lt;p&gt;So as we say goodbye to 2023 (and January 2024… ahem) and move into 2024, let us look back at what we accomplished as a community... by looking at some &lt;a href=&quot;https://i.stack.imgur.com/pmN7M.gif&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;em&gt;exciting&lt;/em&gt; stats&lt;/a&gt;.

It will consist of a family of fonts for text together with a family of fonts of matching style for math mode.&lt;/p&gt;&#xA;&lt;p&gt;Since there are many typographical choices and specificities connected to mathematical practice, I wanted to ask for suggestions/wanted features from other mathematicians, in particular from those working in areas different from mine, which might have slightly different typographical needs which I'm not aware of.&lt;/p&gt;&#xA;&lt;p&gt;As a concrete example of this, having support for letters from other alphabets used as math symbols is important in some areas, such as Ш for the &lt;a href=&quot;https://en.wikipedia.org/wiki/Tate%E2%80%93Shafarevich_group&quot; rel=&quot;nofollow noreferrer&quot;&gt;Tate–Shafarevich group&lt;/a&gt; in arithmetic geometry, or よ for the &lt;a href=&quot;https://ncatlab.org/nlab/show/Yoneda+embedding&quot; rel=&quot;nofollow noreferrer&quot;&gt;Yoneda embedding&lt;/a&gt; in category theory.&lt;/p&gt;&#xA;&lt;p&gt;A different kind of suggestion would be LaTeX specific optimisations or features for fonts which would be nice to have in practice, including e.g. a &lt;a href=&quot;https://tex.stackexchange.com/q/483976&quot;&gt;bigger set of delimiters&lt;/a&gt;, or built-in optimisation of microtype through a variable width axis (as e.g. discussed &lt;a href=&quot;https://tex.stackexchange.com/questions/634421&quot;&gt;here&lt;/a&gt;), a feature relating to the text part of the font.&lt;/p&gt;&#xA;&lt;p&gt;That said, in a vacuum a question like &amp;quot;Suggestions for features a math font should have&amp;quot; would arguably at best be a soft question, and at worst off-topic for MathOverflow. Nevertheless, given the free, open-source, nature of the font and the fact that ultimately it will be available to the broad mathematical community, I believe it would be reasonable to make an exception in this case, asking for input &lt;em&gt;from&lt;/em&gt; the broad mathematical community as part of developing the font with the community in mind, and I believe MathOverflow would be a nice place for receiving this kind of input.&lt;/p&gt;&#xA;&lt;p&gt;So―would it be okay to ask such a question in the main site? There I would define the exact gap the font is meant to fill, as well as give examples of the kind of input I'm looking for as an attempt to focus the question and define it a bit more clearly (although any input is going to be more than welcome)&lt;/p&gt;&#xA;" OwnerUserId="130058" LastEditorUserId="130058" LastEditDate="2024-01-28T18:10:41.467" LastActivityDate="2024-02-08T13:29:47.447" Title="Suggestions for the design of a font for math articles/books" Tags="|discussion|specific-question|on-topic|" AnswerCount="2" CommentCount="23" ContentLicense="CC BY-SA 4.0" />

This includes all the usual math symbols as well as font families for &lt;code&gt;\mathbb&lt;/code&gt;, &lt;code&gt;\mathsf&lt;/code&gt;, etc.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;I believe &lt;a href=&quot;https://typedrawers.com/discussion/2630/elemaints-a-serif-family-with-optical-sizes&quot; rel=&quot;nofollow noreferrer&quot;&gt;Linus Romer's Elemaints typeface&lt;/a&gt; will fill the above gap well too once it's ready. Darwin will then work as an additional option with a significantly different style, similarly to Computer Modern vs. Palatino or Libertine.&lt;/p&gt;&#xA;&lt;p&gt;Currently the regular style of the font looks like this (please ignore the bad spacing):&#xA;&lt;img src=&quot;https://i.stack.imgur.com/NWfJI.png&quot;&gt;&#xA;PDF samples in English, Russian, and Greek are available &lt;a href=&quot;https://drive.google.com/drive/u/1/folders/1Vn4KtMrHfKLAKHFnRbZQcr3rz48h6U08&quot; rel=&quot;nofollow noreferrer&quot;&gt;here&lt;/a&gt;.

For example, these include:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;The use of symbols that are specific to certain areas and not covered usually, like the hiragana よ for the &lt;a href=&quot;https://ncatlab.org/nlab/show/Yoneda+embedding&quot; rel=&quot;nofollow noreferrer&quot;&gt;Yoneda embedding&lt;/a&gt; in category theory, the Cyrillic letter Ш for the &lt;a href=&quot;https://en.wikipedia.org/wiki/Tate%E2%80%93Shafarevich_group&quot; rel=&quot;nofollow noreferrer&quot;&gt;Tate--Shafarevich group&lt;/a&gt; in arithmetic geometry, the Cyrillic letter Л for the &lt;a href=&quot;https://math.stackexchange.com/a/703836&quot;&gt;Lobachevsky function&lt;/a&gt; in hyperbolic geometry, the Cyrillic letter Э for &lt;a href=&quot;https://ncatlab.org/nlab/show/evolutionary+vector+field&quot; rel=&quot;nofollow noreferrer&quot;&gt;evolutionary vector fields&lt;/a&gt; on a jet bundle in some articles (e.g. &lt;a href=&quot;https://arxiv.org/pdf/math/0410185.pdf#page=14&quot; rel=&quot;nofollow noreferrer&quot;&gt;page 14&lt;/a&gt; of &lt;a href=&quot;https://arxiv.org/abs/math/0410185&quot; rel=&quot;nofollow noreferrer&quot;&gt;arXiv:0410185&lt;/a&gt; on the geometry of PDEs (as pointed out by Igor Khavkine), etc.&lt;/li&gt;&#xA;&lt;li&gt;Better glyph support for &lt;code&gt;\mathcal&lt;/code&gt;, &lt;code&gt;\mathbb&lt;/code&gt;, &lt;code&gt;\mathfrak&lt;/code&gt;, etc., ranging from &lt;a href=&quot;https://tex.stackexchange.com/questions/254445/package-for-mathbblowercase-letter-symbol&quot;&gt;&lt;code&gt;\mathbb&lt;/code&gt; for the lowercase alphabet&lt;/a&gt;, to &lt;a href=&quot;https://tex.stackexchange.com/questions/3473/blackboard-bold-variants-for-greek-letters&quot;&gt;&lt;code&gt;\mathbb&lt;/code&gt; for Greek&lt;/a&gt;, to more exotic things like &lt;code&gt;\mathcal&lt;/code&gt; or &lt;code&gt;\mathfrak&lt;/code&gt; for Greek. Appropriate support for these should have the style of the new symbols match the rest of the document, something which current workarounds like &lt;code&gt;\usepackage[bbgreekl]{mathbbol}&lt;/code&gt; fail to fulfill.&lt;/li&gt;&#xA;&lt;li&gt;A preference of &amp;quot;empty fill&amp;quot; over double-strucked blackboard bold or vice versa (i.e. &lt;code&gt;ams&lt;/code&gt; vs &lt;a href=&quot;https://ctan.math.illinois.edu/macros/latex/contrib/mathalpha/doc/mathalpha-doc.pdf&quot; rel=&quot;nofollow noreferrer&quot;&gt;&lt;code&gt;txof&lt;/code&gt;&lt;/a&gt; &lt;code&gt;\mathbb&lt;/code&gt;).&lt;/li&gt;&#xA;&lt;li&gt;A bigger set of delimiters, as discussed &lt;a href=&quot;https://tex.stackexchange.com/q/483976&quot;&gt;here&lt;/a&gt;, for situations where one would e.g. need parentheses bigger than &lt;code&gt;\big(\big)&lt;/code&gt; but smaller than &lt;code&gt;\Big(\Big)&lt;/code&gt;.&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&quot;https://tex.stackexchange.com/questions/634421/&quot;&gt;Built-in optimisation of microtype through a variable width axis&lt;/a&gt;, allowing for an even better spacing optimisation than microtype already wonderfully does.&lt;/li&gt;&#xA;&lt;/ol&gt;&#xA;&lt;p&gt;I plan to address all these points in the development of Darwin, adding all Cyrillic glyphs for mathematics, designing matching families for &lt;code&gt;\mathbb&lt;/code&gt; Greek and alike, having an option available to choose between one of the two styles of blackboard bold above, as well as implementing the LaTeX specific features outlined in Items 4 and 5 above.&lt;/p&gt;&#xA;&lt;p&gt;However, I'm sure the above list is anything but exhaustive, and there ought to be countless more such features which would benefit the community.
