_As requested by Joseph. 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 left this site
 - another top user was suspended (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:

 1. I am European, too
 2. I have no time at all
 3. 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) write 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 TikZ 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.
