Doesn't OpenID have facilities for defining other identity information, such as friends for instance?
I don't think OpenID or any other open schemes will succeed by having information stores divorced from applications. They will only succeed as protocols for existing sites to cooperate. I don't doubt the large players will be slow in adopting this sort of thing, but the smaller companies can bind together.
more than anything, i'm interested in the way that this article seems to acknowledge the facebook's incumbency in the 'social graph' space. he seems to be making the statement that ownership of this graph is at present theirs to lose.
