I am asking this because I caught myself thinking about making a Mastodon account for my PeerTube space, in the same way you used to make a Twitter presence for your YouTube channel.
I realised that I should be able to just use my PeerTube account instead, since it's ActivityPub. That's the whole appeal of the Fediverse!
But since I can't write text posts, read timelines or interact in any way with non-video content on PeerTube, where is the point in federating with the rest of ActivityPub?
Is it only for commenters to be able to use their existing Fedi accounts to comment on PeerTube, and it's more of a one-way thing in reality?
