I am at MashupCamp2 today facilitating. It is really fun to get up there and help 300+ folks make their own agenda for the day. The energy in the room is fantastic. People were asking me to encourage the sessions to be more spread out cause they wanted to go like to 4 different discussions proposed in one time slot.
Johannes Ernst and David Recordon are hear and there are at least two different sessions around identity on the schedule. I am in the first session being lead by Johannes scoping out the problem set and around identity and mashups.
