I don’t stream myself so I can’t speak for that side of things, but just for watching streams the software seems fine but there’s not much content. Same story as a lot of Fediverse systems.
Maybe once the Lemmy/kbin threaded Fediverse takes off (which I think has the potential to be the first federated network to eclipse its centralized counterparts) there can be some synergy with these other platforms that can help them get more users.
