Honestly, I just want instances that focus on niche interests. An instance for sports with communities of different leagues, instances for pc gaming with communities for amd/intel/Nvidia, etc
That way, main instances with more generic context like lemmy.ml or beehaw dont get clogged
I've never used peertube, but I heard it's getting pretty good.
However, after considering hosting a peertube instance, I can see what a large actor such as Google can bring to the table for resource intensive services, such as video hosting
I'm a rabid (addicted) watcher so while Peertube definitely works it just doesn't have the same amount of content on all random niches. Very cool project though.
