Two weeks ago when I was in NYC we had an identity gathering. It was one of those 'open space' kind of days - who ever comes are the right people turns out it was 4 of us Me, Ryan, Tony and Ken Jordan. The person who instigated the meeting Ryan Jenssen because he reached out and asked to help Identity Commons and I said why not have a meetup when I am in NYC.

He is now writing a whole series talking about A History of Tomorrow's Interent on his Dr Star Cat blog so far it is great.
