Out of interest: How do Lemmy and kbin compare to Reddit in terms of accessibility?

Well, it’s actually a bit simpler than that.

You can directly browse a community that technically lives on another instance without ever leaving your instance.

If you’re on the start page of your instance you can e.g. change between seeing Local, Subscribed or posts from all communities (across instances).
You can click around and browse from there without having to leave your instance :)
