I will check these out

FWIW the specific channels I recommended were mostly based on stalking your user profile and grabbing a couple I thought might interest you based on that. But I didn't have much to go on from your Lemmy history specifically. They weren't necessarily the first ones I'd recommend to someone in the general public, or to someone whose interests I knew better.

if only I could figure out how to use peertube

From my experience trying Peertube, its biggest problem for now is just...the server infrastructure of existing instances isn't very good. I got really bad buffering. Maybe better server-side encoding could have helped with that. Maybe they need stronger server hardware with better outbound network connections. Maybe I just need to find a more locally-hosted instance to me. Maybe it's something else. But the user experience was really not good. Which is a shame. As nice as Nebula's sort of worker-owned co-op model is, true federated video would be really nice for those of us not privileged enough to become a member of the exclusive club. YouTube being basically the only real option really sucks, and I'm sick of alternative options like Gfycat dying off and losing all their content.
