Can someone explain the point of federating PeerTube. Their site doesn't really explain it, and it seems like you still need to create an account on every instance you want to use (if you want to comment on/rate videos). How is it different from lots of independent sites, with RSS feeds for each channel?
What I don't understand is why they don't broaden the scope and work more like IPFS, with a thin shell for displaying video data.
The biggest problem to solve is diacoverability, a thin shell is not enough if you want to solve the general problem
