This would not be a first, see arXiv:1909.00177 The citation (which I think follows the best practice) is [6] Fedja, Communication on the MathOverflow website (2018), available online at https://mathoverflow.net/questions/125861

Ironically, this question has been answered in the comments by Tobias Kildetoft. If you see a question which has been answered in comments you can make a CW answer which incorporates that comment. You can also add some additions of your own, and if your additions are sufficiently substantial then it's ok to make it not CW. In addition to what Tobias said, ...

Too few users bother upvoting comments for this to make sense as a policy. In general, only very problematic or absolutely useless comments should be deleted on MathOverflow. In order for MathOverflow to have lasting academic value, the MathOverflow community should strive to maintain as accurate an historical record as possible. A perfect historical record ...

The comment vote rate limitation should be changed to 10 comments per minute. Vote up if you support this alternative, and vote down if you are against.

The citation (which I think follows the best practice) Indeed, that was a good way to handle it :-) The priority here is, as I said many times, to give the due credit to MO and similar sites that facilitate the free and efficient exchange of ideas whenever possible. As to myself, my name is neither really famous, nor totally unknown, so I'm neither hiding ...

Max G.: that's a good question. I think in many cases the decision is based not on policies or guidelines, but an inner sense that the answer (and thus the question itself) is too easy and that the commenter is reticent, either about the quality of the question and whether it deserves to be answered or even open, or about acquiring points in such a cheap and ...

I don't think MO should change any policies just because we're part of a network now. Yes, we are going to get a handful of edits, flags, and otherwise suggestions from SE users which have little to no clue about MO and its community, but that shouldn't really bother anyone. MO worked out just fine, and even better than fine, and it should keep up its ...

No, there is no way to change this behaviour through the current interface. Note from the blog post François linked to that long ago no comments were shown until a link was clicked. There are a number of 'features' of the Stack Exchange platform that discourage comments (or at least lengthy interchanges in the comments), and generally I think this is a good ...

My feeling is that one should not give answers (or hints) to questions that are not appropriate for MO, even in the comments. Doing so encourages people to post inappropriate questions in the hope that they'll get an answer even though the question is closed.

There's a meta stackexchange thread on this topic, here: Cancelling upvote on comment?. In brief, you can change your mind -- "upvoting" again undoes the upvote -- provided that you do it quickly (within 60 seconds) and without navigating away from the page. Otherwise, no, you can't take it back as far as I'm aware. It would be nice to not have to decide ...

I think that this is part of the network-wide changes. We can't control them, and they are applied uniformly across the SE network. The thing is that on sites like StackOverflow, and on many other sites in the network, the community norms and etiquette can be very very very very different from the ones here (and on math.SE, for that matter). It's good to ...

The related question on Meta.SE popped up today and I looked into this to see if I could figure it out. Looks like the misspelling of "Lipschitz" lead to a word that triggers single-flag deletion appearing in the comment, which was why the no longer needed flag immediately deleted this comment. For completeness, my answer on Meta.SE: In this case, the ...

You always have the option of entering a new edited comment and deleting the old one, which has almost the same effect as what you're hoping to do. (That's what I used to do back when it was not possible to edit comments at all.)

I think the remark you want is on page 361 of the Princeton Companion to Mathematics. Edit in response to a comment - the paragraph in question follows: The ABC conjecture has many other marvelous consequences; for a delightful survey, see Granville and Tucker (2002). In fact the ABC conjecture and its generalizations can be used to prove so many ...

I find this proposal completely unreasonable: "the questioner should have the right to petition the mods for a reversal of the vote." For one, think of the amount of workload this would add for the moderators. Moreover, moderator might not be an expert in the area of the question. I think it is optimal if much more moderating is done by community than by ...

I would immensely prefer if nothing were removed which is not explicitly problematic.

No. The best you can do is what you just did after Michael's suggestion: comment to ask the user to post it as an answer if you would like to award the bounty.

That comment was deleted by the user, presumably for a legitimate reason. What you're seeing is a remnant of the notification when the comment was posted.


7

The built-in search only searches in posts (questions and answers), so you will not find comments using that. One method which is reasonable is using Google with restricting to this site. For example: proportionality site:mathoverflow.net. This searches both in posts and in comments. Another reasonable possibility is to use data explorer. You can create ...

That room was deleted, since it contained less than 15 messages, see this FAQ. I used my chat superpowers to undelete it, although it is bizarre that this happens for rooms created from comments. I've added two messages, so that this won't happen again. There seems to be a feature request to make this not happen, but apparently it is a sufficiently rare ...

I am on the opposite end from Andy. My (humble, as usual) opinion is that (barring complete trivialities where you intend to send the person the direct message that he is either too stupid or too lazy to waste your time on or that his question has absolutely nothing to do with mathematics), you should demonstrate that the problem is easily solvable before ...

Comments are third-class citizens on SE. Their purpose is solely to lead to improvements in the post. This can be by correcting mistakes, asking for clarity, or making suggestions of improvement. They are not for discussion -- try to avoid starting a discussion in comments. If you wish to discuss, create a new room in chat. The chat platform is much better ...
