1. Hard to get into and discover channels
2. Services like Grayjay, which can put together both recommendations from PeerTube and YouTube and other platforms for some reason only pull the oldest content from PeerTube
3. A lack of community outside the biggest Linux YouTubers

A few solutions might be to…

1. Somehow find a way to have the PeerTube app work with YouTube
2. Include subscriptions for channels so YouTubers can use PeerTube as a better patreon or ko-fi for storing videos and sharing content
3. Promote better videos which may entice others to stay longer, have users consistently promote the service personally
