I went to this. I can't remember the last time I found a public event of this kind so interesting and so much fun. Fantastic speakers, great venue (who wants to spend a day in the dreary subterranean basement of another corporate hotel?), superb organisation, and a really nice bouncy spirit in the way the sessions were organised and chaired. Just brilliant. Other conference event organizers should watch, and probably watch out.
I hope to post another piece about what was most interesting, but didn't want to leave it another day.
