If I understand correctly, users of other fediverse things like Mastodon can follow lemmy communities (and users?) but the reverse is not currently possible. Would it not make sense for lemmy users to be able to subscribe to a hashtag or user on a mastodon instance?
There is no previous work on Peertube compatibility, it just happens to use Groups for its channels, which Lemmy also uses for communities. Lemmy cant handle videos, but i might look into that.
…and less than a month later, the new lemmy release allows following peertube channels!
thanks, @nutomic@lemmy.ml et al!
