I will miss it but you are right about moderation. I don't know what the issue is on some platforms, reddit and SO come to mind. Moderators on many other platforms or forums seem to be alright and keep a clear head, even when they have to deal with a lot of vitriol and they get little thanks for their work.

There are probably negative examples as well but some platforms seem to be especially vulnerable. If I had to run reddit or SO, I would limit moderation to one subreddit/subdomain. No idea if that would help, but the problem isn't exactly invisible.
