So, after schlepping up from Brighton this morning I've arrived at the Young Foundation in east London for this weekend's Social Innovation Camp.
As Jemima noted yesterday, it's basically a two-day hackfest for people interested in making applications that can make a real difference to people's live - trying to find an answer to the question "can the social web make a social difference".
There's a sort of early morning bleariness to proceedings - it's brisk outside and everyone's wandering around, getting a feel for things and deciding which of the six projects they can get stuck into.
I'm going to roll up my sleeves and see what's happening.
