Even 25 years ago being “too online” - back then it was icq, livejournal, and forums - was already destructive as hell and always led to some pretty cringe outcomes. At least these days some people make a career out of it, back then it was purely negative

It wasn't purely negative for everyone. I still maintain ties with several people I hung out with on an IRC channel in the 2000s, and a couple of fellow heavy commenters on one blog in the same decade. Granted, this was aided by the fact that we were all in Europe and all traveled regularly, so we could do the IRL interaction that solidifies friendships.

Today, if one is heavily online, many platforms no longer offer a space where one can tell a fellow user, "I'll be in your town soon, let's meet up", or even if it does, the general culture has changed away from that.
