#ActivityPub is super cool once you see it in action.
For instance, you can visit the new StarTrek lemmy server here: https://startrek.website/c/startrek. Looks like a reddit sub with posts, threaded comments, upvotes, &c.
OR you can follow the same server on Mastodon @startrek.
Every thread and comment shows up as a boosted post.
Cool, right? Now, say you find a comment that you want to reply to. Post through your favorite Mastodon app, and that feeds right back to the thread on the #Lemmy server! 🤯
@awilbert @startrek hello from Mastodon! Thanks for this post, I’m still figuring out how the federated stuff works, and you helped it click a little bit more! Plus, now I get to see more Star Trek stuff in both Lemmy and Mastodon.
