Lemmy and kbin share communities, https://browse.feddit.de/ doesn't show any kbin insances currently but that could probably be added fairly easily, if the dev wants to.
kbin is quite new so there's not gonna be a large amount of instances, resources, stat sites and so on.
Kbin specifically has been overloaded and is currently using cloud flare to stay up. This is creating federation issues right now.
Funnily enough, I'm here because of those issues. It's becoming way more clear how this fediverse stuff works when I can actually see it and not just read the concept.
