I think what made the internet in the 90s and early 2000s more enjoyable is that it was way smaller than now and (mostly) free of bots, and trying to find that in social media and mainstream sites is counterproductive, since they are just the opposite.

In comparison, I've found small net places such as Mastodon or smolnets much more enjoyable even though the population is much smaller (which is nice since they also don't generate more information than I have time for). As a rule of thumb: The less interesting a place is for companies, the more pleasant it probably is.
