a tad expensive eh?
Not really, you get two full days of awesome speakers, workshops and get to put faces to forum names and network. The people attending this are THE people building the bitcoin economy and I'm not even talking about the speakers.
For early arrivers there is the hackathon that started today, and will be continuing tomorrow, Friday night there is the meetup in a pub (going to be a lot of people at this one), then Saturday and Sunday night there is an 8bit party.
You can't put a price on what is happening here, I've never attended any tech conference, but I'll be damned if I miss this one.
paid in BTC, would be interested in meeting up with some fellow UK bitcoiners etc so PM me if ur going
