Not sure if I agree with that as a blanket principle. I've seen quite the audience / faction building on forums and subreddits in the past, sometimes by sociopaths and often ending in tears. It's probably easier to do on an IRC channel or nowadays on X, a discord or telegram group though, so maybe it would be fair to say "there are better places for this than fora"?

Not so much an antidote, as underoptimized for it?

Forums in general seem to push people away from building audiences -- maybe because identity is not as important as content on forums (is this true? I think it is, also it's not my idea).
