Quick question for PG. Would you be interested in running a similar event in London? We've been organising an HN meetup for over a year and currently have a community of over 1100 people that would love to attend an event like this. There are also several YC companies including Songkick that have been involved in the meetup that I am certain would be interested in helping out.
Possibly. If we had an event in Europe, it would probably be in London.
As one of the founders of http://www.44con.com/ I'd be happy to chat about making this happen. We have everything we need geared up for this and could do it as a free or paid for conference.
