What's the fundamental difference between Fediverse/ActivityPub/Lemmy and the Usenet?
After reading a bit about Usenet, it seems to me as if the whole Fediverse seems to be just a reinvention of Usenet.
What's the big difference?

Not super educated on the subject but I'm pretty sure Usenet was just one platform/standard whereas the fediverse is a bunch of interoperable standards. That's a pretty huge leap I functionality
Fediverse is one standard - ActivityPub.
Yeah but there's different ways to interact with the fediverse via activitypub, whereas Usenet was just. Usenet
It’s actually several standards, the primary one is activitypub but mastodon also uses webfinger, and for example peertube uses p2p transfers to serve video
But they aren't compatible, are they? Which would make it multiple, disconnected fediverses.
No, i can follow and post to mastodon accounts from here, and I’ve posted my cat to !cat from my mastodon, sometimes you lose certain fields (mastodon doesn’t really know what to do with upvotes, so it doesn’t display them when I’m logged into mastodon) but the post works fine on lemmy. I also follow peertube accounts from my mastodon too
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !cat@lemmy.world
The Usenet is a very old and federated system. Same as the Fediverse, the Usenet is based around a single protocol (NNTP vs ActivityPub which Fediverse uses). Same as on the Fediverse, there are lots of different applications for it, that represent data in a different way.
