I just rejoined PeerTube after I had a quick look years ago, and it’s gotten way better since then, actually. I found out Space Quest Historian is on it, too!

But yeah, discoverability isn’t good. Lack of an algorithm also makes bingewatching impossible - for better and worse, I guess.

As you linked them, I’d also recommend peertube.wtf - they even reacted very quickly when I reported a transphobic german conspiracy channel/server.
