About 20 years ago, one of my A-level friends set up his own site and discussion forum with phpBB. I still have friends from non-corporate IRC servers, and can even recognise a few Hacker News usernames from some of the channels I was on, though the relationship there is more of “in the same place at the same time quite often” (/me waves to @duskwuff ;)). It wasn’t all Livejournal and AOL chat.
