Apparently they crammed it all into one day this year and the tech stuff was held separately (downstairs) from the general stuff (don’t want those devs and general users to mingle, ruh roh!)
I don’t fly so I was hoping for some audio or video recordings. I found a live video feed from some bloggers upstairs but nothing downstairs (at least not that I could find). I need to hunt down the slideshows for Crazyhorse, BuddyPress, Nginx etc. Finding a schedule of the tech stuff would probably be a good start, I found one for the general stuff upstairs but not downstairs. ZDnet covered only the non-dev side, but in detail.
