It’s a chicken or the egg situation. However you make your money you need eyeballs and they’re currently not on PeerTube. Millions of people visit YouTube everyday. That’s a lot of chances for discovery. It’s a very small percentage of people willing to limit their exposure for the things you mentioned and without loads of content it’s hard to grow and truly be an alternative to YouTube.
That stinks and it is an excellent idea. I’m really enjoying it.
