ActivityPub magic?
So you can tag Lemmy communities from Mastodon like @tech and it just makes a new thread on Lemmy?
My imagination is a bit small, so I’m not seeing the immediate utility of this. How do you vote/downvote? How do you subscribe to a community? Those interfaces aren’t present on Mastodon.
Subscribe by following the community handle, like @tech. As for voting, some of us don’t mind not being able to do that. If I decide to start caring about that, I guess I’ll get an account on a proper server that handles this feature.
