I have noticed that a two line answer that anyone can come up with usually has more upvotes than an answer that is more difficult to come up with. Is this trend simply a result of pure laziness as ...

The question "The probability for a streak when tossing a coin" is on hold. [Edit: It has been reopened.] I disagree with closing the question and voted to reopen. This problem may sound like it is ...

I don't know much about the culture of MO. So I would like to ask the following question. Is it OK to ask the reason for a question in the main to be on hold or closed in the meta?

This question was originally asked in MSE about a year ago. Nobody has answered it. So I posted it here. I wonder why they think it's not of research level.

This is motivated by this question, see also the comments, and Will Jagy's answer. I was asked to start a formal request, so here it is. A user that has expressed no desire to participate anymore on ...

NEVER MIND --- the same moderator who suggested I post here has solved the problem by deleting my copy-paste job and undeleting the answer we wanted undeleted. [or maybe it got undeleted by some other ...

One convenient thing on AoPS that is missing on MO is the private message system where you can send and receive private messages to other users without figuring out who they are outside the internet ...

See Why is differentiating mechanics and integration art? Which functions of one variable are derivatives ? both of which are tagged [tag-removed]. Also, both of these seem to have had these tags ...

I'm just asking. When an MSE account is temporarily suspended to cool down, then the expected outcome is that the user would start doing the same things on MO which led to the MSE suspension. This ...

Right now, there is a question posted on MO that rightly does not belong to MO: The equivalence of the mathematical induction and the principle of the smallest. Of course, such questions comes and ...

MathOverflow has a few problematic tags which are not inappropriate by themselves but suggest off-topic ideas. A prime example of this is the calculus tag. Sometimes a research-level mathematics ...

When a new member tries to write a comment he sees “add comment (requires 50 reputation)” but of course he has no so many points. On the other hand, answering does not require any reputation. Then the ...

Recently I have placed a bounty on this question. The question has no answer in technical terms, but it has been answered in a comment within the bounty period. Now the banner below the question says ...

If a user deletes their account on MO will all the associated accounts on other StackExchange sites be deleted as well?

I just came across an answer by a new user which looks very unusual to me: https://mathoverflow.net/a/139275/21095 Specifically, there is very little mathjax in this answer. Instead the vast majority ...

This is a place to collect MathOverflow success stories! Was some of your research inspired by something on MathOverflow? Do you know questions & answers that led to interesting research? ...

I feel like an idiot but I cannot find it. Meanwhile, if the post is long and has a lot of LaTeX formulae in it, and the connection is imperfect, the wysiwyg regime is a non-stop fight. I figured out ...

I voted to close this question about a "5n+1" version of the Collatz conjecture because it appears to be entirely unmotivated, with no heuristics and not even any substantial numerical evidence. I ...

I've noticed a message in mathoverflow's place for comments saying that '+1' or 'thanks' comments are not appropriate. I don't agree with the second kind of comment being inappropriate. I think it's ...

In the old meta we had a very useful thread where one could point to moderators multiple accounts to be merged. Since things have changed, would there be a point on having such a thread here, or what ...

I noticed tonight that a well-intentioned user has been doing a lot of minor edits of formatting of old questions with the effect of filling most of the active question list with old questions bumped ...

Edit: I have retagged this question 'feature-request' in an attempt to expedite action on these issues. I request that the MathOverflow developers implement an automatic fix of the issues in the ...

There's nothing much to this question, but I thought I'd ask anyway. When a question is flagged as a duplicate, a comment of the form "possible duplicate of . . ." is posted. Why isn't it "Possible ...

Should question titles, which sometimes intentionally avoid LaTeX math for those who choose faster rendering, be edited to insist upon LaTeX math? A recent instance that prompted my question is "two ...

After the migration, it appears that the hyperlinks in my profile description are no longer working. I've noticed the same problem with some other users who I seem to recall had working hyperlinks ...

There is a long list of comments in Migrating a question which is already posted on the other site, and an important question is deep in that list, so I repost it here. Where in the legal agreement, ...

When a question begins by saying "This question appeared earlier on math.stackexchange.com" and links to that earlier posting, how does it make sense to migrate it to math.stackexchange.com (thereby ...

On SE and on the old MO have seen @someone in a question. Probably this notifies someone in his inbox and draws his attention (which is the goal). Does it really ...

It would make sense, especially for MO, to have an option to hide migrated and on hold questions in the user preferences. Is there a way to do this already? If not I think this would make a nice ...

We should add the option to migrate to Theoretical Computer Science when voting to close. This question is an obvious candidate.

I'm wondering if it would be appropriate to ask a soft question on MO regarding mathematical etiquette. In more detail, I'm writing a paper that cites a well-known paper in my field, but I've been ...

A user over at MSE flagged https://math.stackexchange.com/questions/455506/why-cohen-macaulay-rings-have-become-important-in-commutative-algebra#question suggesting that it is suitable for MO. The ...

We had an old thread about this at tea.mathoverflow.net but this is not the most obvious place for that. Where should we keep track of cool success stories like this recent gold nugget? Update: The ...

Evidently maths.stackexchange redirects to math.stackexchange, but there is no apparent mathsoverflow.net. Granted, sover is not a word. Anyway, the suggestion is to create a thing called ...

I only posted two questions on meta, both fact based and both about the way MO is supposed to work. Today, I realized that I have received three down-votes. I have a feeling about down-votes (and up-...

At the beginning of the summer I had around 1,172 reputation points. I didn't log on for a few months. Then, I saw that the site looked a little different and I looked at my profile and saw that I ...

This old post on meta stackexchange contains a script that hides posts from users of your choice. There were some negative comments there and the script doesn't seem to be working anymore (maybe ...

I would like to know, whether it is in the line of MO rules to present a result and ask for "opinions" like whether it is already known or worth pursuing and, who might be interested in the result. ...

The review queue for late answers and first posts has the option "No action needed". Its description says that I should use it if no action is needed from me. This specific description confused me ...

We frequently have questions that are crossposted, e.g. https://mathoverflow.net/questions/137414/systems-of-parameters-for-algebra-a#question. The only options for now are to close as off-topic, ...

I would like to take better advantage of comment notifications. Where can I find a complete account of how they work? For example, it appears that writing @FullUserName in a comment will lead to a ...

I had a question that was on hold with a -1 vote. The vote increased to 0, presumably due to my edit. However, I see that it has been closed. I'm unclear as to why. The question is here: Torsion and ...

I hope that I am following the instructions listed at How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion?. I would like ...

I have recently attempted to create the obvious tag synonym 'dg-algebras' <--- 'differential-graded-algeb'. However, my attempt was thwarted by the system's insistence that I need five total score (...

The Analytical badge is retired, presumably because it is no longer possible to obtain it. If this is not the case, please let me know. If it is the case, shouldn't the Precognitive and Beta badges be ...
