I'm getting ready to give my keynote at MacHack. At midnight. That's the kind of conference this is -- the opening keynote is at midnight. I am assured that these folks will hang around for the talk, and that at previous conferences they have stayed for hours. I do not intend to take hours -- who has that much useful to say at midnight? Not me, for sure.
The conference is based on actual programming, as the name might imply. The idea is to do actual things while at the conference. It runs 24/7 for three days, wireless everywhere, write something cool, share it around. More conferences should be like this.
