I did, but I really see this as closer to 'finger'... perhaps even indistinguishable from it at this early stage. FOAF has been around awhile (tho obviously not as long as finger), and I've just never seen anybody use it, or was blind to it when I saw it.
I definitely see some kind of 'friend' association with Personable in the future, but it's not a social network, so I'm totally vague on how those associations might work.
