Hello, you might have noticed (or not) that posts from kbin, more specifically kbin.social aren’t showing anywhere, this is due the DDoS protection they currently have on. So even if you are subscribed to kbin.social communities you won’t see any posts from the outside.
Same is happening inside kbin.social where users there cannot see posts from the outside. This is however temporary and the admin is working on getting federation back online.
The site is currently reporting 125k registered users https://kbin.social/stats.
The no federation is recent (and due to the antiDDoS measures as mentioned in the post). I’ve engaged with some communities on their and talk with some people from it. I personally haven’t checked it out, but a lot of what I’ve heard is that it’s an easier onboarding experience.
Joining is immediate, where some Lemmy instances require manual approval even now.
The main page comes off as more approachable and familiar. They also have a ton of local communities (or “Magazines”) so people can do a lot even without the Federation. I find the Microblog stuff somewhat confusing, I think because it doesn’t have much of a UI built around it so it is less familiar than Mastodon. It is fairly centralized though, in the sense that there aren’t that many kbin instances out there.
