I've spent a week in the Tildeverse now, and I'm definitely having flashbacks to the 90s. I've read the tilde usenet news (which is sadly rather inactive). I've played a couple of runs of the crawl game. I spend a lot of time connected to tidle.chat IRC. #tilderadio is a lot of fun.
So, yeah, it might as well be 1995 for me all over again. The main differences are that I actually know how to use computers now and I'm choosing to use this "archaic" stuff rather that it being all that's available.
So far, so fun.
