Omg I just asked the same question!
(Edit) My bad I just realized it was my post.
/kbin meta
Magazine dedicated to discussions about the kbin itself. Provide feedback, ask questions, suggest improvements, and engage in conversations related to the platform organization, policies, features, and community dynamics. ---- * Roadmap 2023 * m/kbinDevlog * m/kbinDesign
Just wanted to let you know that this is the best thing I’ve read on the fediverse, and by a fair margin at that.
No, kbin.cafe is not run by the same person that runs kbin.social; here's a post by the owner of kbin.cafe and @ernest is the owner of kbin.social and the main developer of kbin. As you mentioned, kbin works similar to an email service, so different kbins (and lemmys and mastodons) can communicate with each other.
That is really cool. I dont go online often but I like that they can all communicate.
You can also connect to non-kbin sites, including Lemmy and Mastodon! They all use the same protocol to be able to talk to each other.
