Must know/use sites for newcomers to the fediverse?

Im right now using lemmy/piefed but what other neat projects should i look into as a newcomer to this world?

Im not looking for anything in particular, i just want to expand what i use and see more projects.

FediDB lists 67 software projects in the Fediverse. Just scroll through it and try whatever suits you.

My personal favorites:

  • PieFed (Threadiverse)
  • PeerTube (Videos)
  • Mastodon (Microblogging)
  • Bookwyrm (Books)

And lately I scrolled a bit through Wafrn, it’s a whole different vibe over there. I don’t understand much, but that’s what I love about it.

Can you explain PeerTube? From what I gather, people set up their own instances for their stuff and no instance allows sign ups. So I need to create my own instance in order to even get a feed and notified of new posts?

Bookwyrm is nice, but it only knows about 20% of my Goodreads book shelf.

And Lemmy has about 1% of Reddits users but here we are.
