Besides Lemmy which I love a lot, I’m also enjoying a microblog platform called Catodon, which is much less basic than Mastodon and has a very nice interface. Pixelfed is also fantastic if you like photography rather than just being Instagram influencer nonsense. Where else are you hanging out? What have you liked and not liked?
PieFed - another lemmy-like platform. Its codebase is deliberately simple, so it’s something I’ve also been able to contribute to (which is nice).
I just read about that one, I’ll come join. More fediverse the better.
