Usenet was the golden age of Reddit for its time. Before the binary newsgroups drowned everything out and web 1.0 captured everyone's attention.
In a way, it was a lot like Lemmy. Federated servers all inter-exchanged posts to a giant, global message board of newsgroups (roughly analogous to a subreddit or Lemmy community). Anyone could create a newsgroup and there were a lot of them.
When it was good, it fostered the same kind of genuine conversation that Reddit and Lemmy do when they're at their best. It was full of memes, too, although that word didn't exist then.
I haven't actually used that account other than to verify it is still there on my old university's servers, in almost 20 years. I probably should try it out again.
