#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! 🤯
I have high hopes for ActivityPub/the Fediverse, but it has some usability challenges. For instance finding this post on my server so I could comment took more than 20 minutes.
Took me a while, too. The federation concept is awesome, but I think there needs to be an easier way to discover what’s available.
