That “little more complicated” is asking for a lot, though.

Say you’re coming from Reddit, or Facebook, or something.

It would not be unreasonable to believe that, like Reddit, every single Lemmy instance is its own separate, self-contained site.

And that’s even before figuring out federation works, and how to access things from outside of your instance, or all the nuances that come with defederation and all of that. You made the mistake of joining beehaw? Whoops, all the other “subs” are now inaccessible, because beehaw is not connected to any of the others.

Central places like Reddit don’t have that complexity. Reddit communities are singular, and there’s no overarching layer to complicate things. A community that disagrees with another, and blocks them doesn’t affect your experience as an user.
