To be honest, I had the feeling it is lopsided the other way around at the moment: There are quite a few good and passionate content creators, lacking in an audience and interaction. I mean - sure - it does not have the amount of content of a big tech platform like YT, and not enough to binge watch stuff all day long, but I think lack of an active audience is at the moment more pressing - as is discoverability. If not using outside channels - like promoting on their Mastodon accounts primarily - or using places like !peertube@lemmy.world or !peertube@lemmy.wtf to discover things, a lot of worthwhile content right now flies under the radar. And that is excluding unofficial mirrors of YT content, which I tend to avoid.

On the other hand - I know lack of a mobile app has come up at several times in comments on there, and I have myself by now anecdotally heard from a few people wanting to try PeerTube and then being weirded out by the unfinished mobile app in ways that were unrecoverable. In addition, adding more know-how and codebase for mobile applications into the greater FLOSS ecosphere and Fediverse is good in its own right, there is a severe lack of it.
