Let me answer from the perspective of someone who is not a mathematician but follows this community for certain topics of interest. This is a community of professional mathematicians where, indeed, questions are usually very well researched and posed, and there's virtually no risk of rewarding homework dump. So, if there's a community in which questions' ...

I am intrigued by this idea and I think it would be a wonderful thing if it gained the support and acceptance of the MathOverflow community. So I am supportive of further discussion of the proposal. My opinion is that our current refereeing process in mathematics is basically broken, and that the professional mathematics research community should pursue ...

I am profoundly opposed to the "cargo cult" question. The internet is full of places where one can indulge in the pleasures of righteous indignation by mocking the failings of others. I absolutely do not want Mathoverflow to join that sorry list. People who agree with me have every right to vote for re-closure, as many times as necessary, and I hope that ...

I feel your pain. :-) But as for the first question, I would say no. 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. I haven't ...

Currently, KaTeX supports a limited subset of the functionality provided by MathJax. Many of the missing functionality (notably arrays and equation alignment) is regularly used on MathOverflow, so I would not recommend using KaTeX for viewing MathOverflow. http://github.com/Khan/KaTeX/wiki/Function-Support-in-KaTeX http://docs.mathjax.org/en/latest/tex.html#...

If there is a specific mathematical question about a specific point in the paper, then there is no problem with discussing it on MO. This has been established by consensus on numerous occasions. In particular, there does not seem to be a problem with the use case you suggest. We mostly recommend against broader discussion about the paper as a whole or the ...

There are few things on MO more annoying than posting an answer and then seeing that answer deleted before it even had a chance to be seen (except by the account that asked the question). All that work for nought. Occasionally though there are circumstances where the question-asker has a really compelling reason for deleting a question as quickly as possible....

Let me make a suggestion which seems obvious to me: You should only vote to close a question as homework if you can solve it. By this I mean you have actually thought through most of a solution, not that you think "oh yeah, I could probably do that." Both here and on math.SE, I frequently see questions attract closed votes because they are formatted like ...

I see your point and it makes sense. However, it is a fundamental aspect of community moderation that edits should be anything but discreet. It also makes sense for editors to be clearly visible as that information is very useful for moderation tasks. That said, I agree that it is not necessary for the editor to be the same size as the original author as it ...

The vast majority of people who write the most common low-quality questions are not going to read this page at all. I think the people much more likely to read this page are those, especially graduate students, who are very nervous about asking a question on MO. They need some encouragement and some advice on how to present a question to ensure it is well-...

I received a huge reputation boost from this change, but I still think that answering a question still takes much more effort than writing well-posed questions. Coming up with a good mathematical question is rather easy, one usually is in a specific situation, wants to draw a certain conclusion, so one adds a couple of assumptions that make obvious ...

Other reasons to downvote a question is if one doesn't think it demonstrates sufficient research effort, or isn't deemed to be useful. In fact, the question-downvote tooltip says this explicitly: These are of course subjective metrics, and can at times seem to be done at a whim without any real justification. But this does not mean that the voter didn't ...

Need: Most importantly, a true preview which shows me exactly what I have written and which I can look at without affecting my LaTeX. Support for at least the symbols in standard LaTeX and amssymb (including amsfonts). At least one of array or matrix. Both inline and displayed math. Currently have and very much want: Simple user defined macros. (I'm ...

This is not an answer expressing a preference, but one giving some resources for people to consider. Intmath.com made a Speed Comparison Test between KaTeX and MathJax. MathOverflow is currently running MathJax 2.7.5; the new version that is MathJax 3 runs significantly faster. KaTeX does run even faster still. There are some breaking changes between ...

Vote here if you disagree with introducing error flags, and think the proposal should be withdrawn.

Long-term archiving is a valid and important issue, but I do not think it should be done via thewinnower.com. This is a problem I feel we can and should solve in collaboration with libraries or archive.org, without the need to involve an additional party (especially an unknown one). Our current coverage by archive.org crawls is good enough for most purposes, ...

Closing a question prevents new answers to be added. If one could close a question with a bounty, the net effect would be to shorten the bounty period, possibly causing the loss or misattribution of bounty points. On the other hand, adding a bounty to a question can be used to prevent closing a question, which is a misuse of the bounty system. Since there ...

If a question has positive score or an answer with a positive score1, closure will not imply deletion (and closure is not necessary for deletion). Thus good old questions are not lost even if they get closed, so I see little reason to introduce additional safeguards (although I see no compelling reason to close old questions, either). If someone finds an ...

I don't have a strong opinion on this subject, but insofar as I have one, it is this: Changing the rules is more trouble than it's worth. I lost points back when +10 was downgraded to +5, and I gained points when the +5 was upgraded to +10, and in both cases I was mostly annoyed that the rules had been changed for (what I perceived as) no good reason. So I ...

After letting this slip through the cracks for a couple of years, I'm pleased say we've implemented Scott Morrison's solution: (Ignore the "mod" link if you aren't a moderator.) We did talk about replacing the share link, but decided it was potentially confusing for users of other sites. Currently the citations are active on the following sites: Computer ...

Such a system would be technically impossible since we can't delay posting a question until tags have been approved. However, this is not a serious problem: Only users with at least 300 points can create new tags. Users are quick to delete inappropriate tags from posts. Unused tags get purged in 24 hours; single use tags get deleted after 6 months. ...

Of course we want the badge. If 1000 people use the link and come here, but 997 of them never come back, we have lost very little. But if the other 3 find out about MO and do become regular participants, then we have gained something. SO ... I don't intend to do it, but if someone wants to get lots of gold badges by this method: Go for it!

There have been discussions and ideas surrounding decaying votes, along with weights of votes themselves. I've got mixed feelings about both. It's important to look at the utility 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 ...

Here is a specific example Embed a bordered Riemann surface into punctured Riemann surfaces? The user apparently asked only one question, it scored 4 and was deleted 2 minutes after I entered the answer.

As mentioned in Emil Jeřábek's comment (which quickly gained several upvotes), at least some of the "network-wide stuff" (Meta Stack Exchange posts, blog posts) can be useful also for MathOverflow users. Let me suggest an alternative proposal to the complete removal of those links from the community bulletin. Suggestion. Reorder the links in the community ...

I share the view by one of the moderators in the post you have linked to that providing such a tool is a bad idea.

DOIs are in some sense just like URLs, but with some differences. In particular, a DOI can be transformed into a URL by prepending http://dx.doi.org/. A DOI is intended to be a permanent name, that will not change meaning over time. On the other hand, a URL may become obsolete (for example, if MathOverflow was forced to move to a different host name, or ...
