@YemonChoi I have pinged this particular editor on the main. (So that your "grumpy plea" gets at least to him.) I am not sure whether you think it is necessary to contact also the reviewers who approved the edit.

If you think that there is a reason to make more people aware of the issue, bumping that old discussion on meta could cause some people to notice it. (And remind some users who have forgotten about that discussion.)

For example, adding the editing tag seems like a reasonable thing to do. Perhaps there are some typos in the question or the answers. (Since I am below 2k, I cannot edit posts on meta. So basically it's up to you - the question is whether it is important enough to revive the discussion by bumping that post.)

Of course, it is possible that a few users will notice this simply because it was mentioned here in chat.

@MartinSleziak I know this is your POV, but I think you said that you are not such an active user of MO? I am, and I use the front page (rather than the "new questions" tab) because I want to be aware of older questions that attract new, good answers; sometimes I didn't notice them on first go. Having old questions and answers bumped for purely cosmetic reasons, or because someone is over-enthusiastic about what they think is correct grammar, just creates noise for users like me.

@MartinSleziak Obviously, fixing broken markup (to fix alignment or MathJax issues) is fine. Changing Z to {\mathbb Z} or Z to {\bf Z} -- the latter is what everyone should do, arguably, but that battle seems to have been lost -- is not, in my view, sufficient reason to resurrect things

@YemonChoi Considering that Asaf's answer has score 19 at the moment, I am not the only one who thinks that editing posts is useful.

I do not edit much and I try to edit mostly recent posts.

BTW since I am below 2k, I cannot do much harm - all my edits have to be approved by more experienced users.

And the comment you're objecting to was my effort to let the editor know about your objections. You can easily ping the editor in the same thread and if I misinterpreted what you wanted to say, you can add better explanation.

@MartinSleziak I note that Asaf also expresses a preference for not resurrecting old questions, which is my particular bugbear. I am not saying "improving posts is a bad thing". I am saying "people making trivial improvements, some of which are based on a false sense of knowledge, creates noise"

Point taken.

Maybe the difference is what people understand under trivial improvement.

Indeed. This one, for me, is trivial (and look at the date) mathoverflow.net/review/suggested-edits/65175

Although in fairness, that edit came after the question had already been bumped by someone adding a tag

mathoverflow.net/posts/87835/revisions

I think that if question was bumped, it changes the game.

@MartinSleziak Agreed. (Wow, online agreement.)

As for myself, I can promise you that I will try to refrain from editing older post. (Although there are some cases where it is difficult to resist.)

BTW I see that you are among the most active editors at MO. Would you mind if I add you as a room owner? (So that there is an owner who belongs to MO community.)

One thing you can do as a room owner is to pin messages. (For example, if you want to pin the "grumpy plea" to the starboard.)

The way I understand it, quid did not want left the room without an owner when they were leaving. And I was around. (I think that after some time the room will die anyway, since both Ricardo Andrade and quid are not active on MO anymore. As far as I can say, they used to be the most active users in this chat room.)

Still, in case it might be useful, perhaps it is worth giving this room a chance.

Other things the rooms owner can do is to change the feeds in the room. That's about all what I can think of from the top of my head.

Speaking of bumping old questions, quite an important difference between MO and math.SE is the number of questions asked. If there are 500 question per day, bumping a few old questions will go unnoticed. Situation is quite different with 40 questions per day. stackexchange.com/sites?view=list#science-questions
