Voted for Affiliated Community.

Affiliated community, but follwership is a closely related second. Here by followers I mean people who pay attention to a user, not merely the mechanical act of following—which is purely psychological shorthand.

Since the whole chain is visible it's relatively easy to have many curated lists of users one follows. It doesn't have to be a published fact on the blockchain.

But as long as the 'Follow' button is there, most people will use it like it means something. And so it will.
