Thinkibng about the aggregation of identity problem. Will people want differnt faces, or different APIs and tools? If they just want diff. faces they'll probably handle it manually. Maybe the future motto will be:"every man a clique," with people building up identity capital, measured in web-space, with yahoo and google acting as a unified index. It's weird (and possibly socially significant,) that googling my name comes up with my other blog as the first entry, above other online references.
