Hmm I get your point, but on the other hand, I suppose nowadays many people are just used to look for a niche community … and finding it. So it’s not a huge surprise if the first reaction is disappointment when you don’t find anything like it or just an empty community.
Well, but that basically means I’d have to rely on different platforms if I want to post and discuss, say, niche music that’d just be buried immediately in the usual “popular” music communities (that often have a slightly rockist slant).
Even on reddit, the ambient music or IDM communities are fairly small.
I feel like people mistake YouTube for a video hosting solution.
But that’s not the point.
So, if the only thing you’re looking for is a video hosting solution, then, yes, PeerTube might be an alternative. In the same way uploading videos to your own webspace would be, and Vimeo also still exists.
But for all the other stuff, YT is, unfortunately, unmatched, and probably will be for a while …
