I read that Kbin defederated with Lemmy because it couldn't initially handle the influx of new users migrating from Reddit, but that it has federated again.
So is it a Lemmy instance, like Beehaw?
I know that Kbin doesn't use communities ("/c/") but uses magazines ("/m/") so I thought it was different.
I also read that there was some new way to post to Lemmy from Mastadon, but I thought those were different, like Reddit and Twitter. But they both rely on something called "ActivityPub"?
So is Kbin similar to Lemmy (by being Reddit-like), but distinct like Mastadon (which is Twitter-like)?
I didn't have a Twitter account, but was a heavy Reddit user. I don't have a Mastadon account, but I'm liking Lemmy. However I have some FOMO about Kbin because I don't understand how it all works together.
I have been exploring Kbin a little bit and can answer some questions.
ActivityPub is a protocol for sharing content. That content can be of multiple types like posts, threads, blogs, videos, microblogs, etc (I forgot the exact names of those types so the names might be off). On Lemmy we have communities, which are comparable to subreddits, that are hubs for ActivityPub content of the thread type. Mastodon is build for microblogs, which are similar to tweets.
Kbin is indeed similar to Lemmy, as it also runs on ActivityPub content, but apart from having communities (which they call magazines), you can also post and read microblogs there.
So if you like Lemmy but you're also on Mastodon or are interested in that, maybe Kbin is more suitable for you.
