hey,

I don't know much about the history, but your mention of Circle of 
Trust brought to mind the PGP trust referral system.  It was a sort of 
network of positive nods, and the more trusted a thumbs up, the more 
trusted the "thumbee."  This is a form of social network, but I don't 
know when or where it actually fits in.  Worth a look for the broad 
landscape, I reckon..
