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?
Mastodon for social-ish media. Peertube for as much video as I can find (its hard, but a couple of creators have mirrored/moved). I want bookwyrm to take off.
