It's foolish to make conclusions about someone's social network based on their key material. If I have a signature from a person, it is not a statement that I know that person, that I approve of that person, or that I would ever associate with that person.
Understood, and I agree it makes no such statement. However, it does make a reasonably good statement that you were physically located near that person at a certain point in time, roughly what that time was, and roughly where (geographically) it happened.
Better than that, though, signatures point to other keys. And self-signatures are signatures, too.
I'll send you some stuff.
