You can check out !updates@kbin.melroy.org , also unlike Kbin, Mbin has an app now, it's called Interstellar and I think it's pretty good
kbin.earth meta
A magazine dedicated to the kbin.earth Mbin instance. Official announcements and maintenance updates are made here, but also feel free to ask questions or request support.
If you'd like, you can also join the kbin.earth Matrix chat for real-time discussion of support, moderation decisions, or just general chatting.
Welcome back! To add to what @Fitik@fedia.io mentioned, there's also !mbinmeta@gehirneimer.de for discussion around Mbin and !mbinReleases@gehirneimer.de for posts about Mbin releases. If you want to get into the kbin.earth/interstellar ecosystem, there's also !kbinEarth (this magazine), !interstellar (for the Mbin app), and !interstellar_configs (for sharing Interstellar configurations).
If you'd really like to get into the history of what happened to kbin.social, try reading this post: https://lemmy.zip/post/20570491
