Joseph required me to set a threshold. Let's say that the answer to the title question is "yes" if this post reaches at least 30 upvotes in one month's time.
Recently:
- three top users deleted their accounts,
- two top users left the site (without deleting their accounts), one of them was suspended several times before (in my opinion, the past behavior of the people involved was not carefully taken into account in this circumstance, as far as I can judge with the little info available)
- in general, I feel that touchiness and rudeness are growing (a couple of episodes make me think that).
I believe there is a problem.
Now we have only three mods, all of them are European.
One of them is English and the other two are German, that is, all of them are Anglo-Saxon speakers.
To cover all the time zones, I think we need, at least:
- an American (better if South American, see below)
- an Asian
- a person from Oceania.
And to better understand misunderstandings created by language barriers, we should also have:
- an African
- a South American.
As marmot suggested in his answer, it would also be great to have a more gender-balanced moderator team, since the current ones are all men.
To clear any doubt, I do not want to propose myself as a moderator because:
- I am European, too
- I have no time at all
- I am mean.
How do the mod elections work? Can we have more than three mods?
Update: Christian Hupfer (one of the users who recently left the site and deleted the accounts) writewrote to me to explain the reasons for his leaving. He authorized me to talk about them, I try to sum them up:
- a growing number of just-do-it-for-me and otherwise boring questions
- too many duplicates answered instead of being closed
- too much attention to TikZTikZ posts, and too few attention to the ones which would deserve it
- too much childish talks in chat (ducks & Co.) and fun posts
- growing rudeness
- ingratitude.
Hence, apart from the growing rudeness, there is not much mods can do.
