Someone asked how they can publish videos on PeerTube (the Fediverse's video platform). There's a guide to publishing on PeerTube here, it includes suggestions for where to sign up (and also how to make your own server if you prefer):
I'm trying to let more people know about PeerTube through my instance https://fedi.video which tries to highlight all the best videos without any toxic stuff, and makes them browsable and searchable in one place. It also links to the guides on how to use PeerTube and has some manually maintained playlists.
I also have an account at @FediVideo which boosts interesting PeerTube videos and highlights interesting PeerTube accounts.
