The DIBI videos are up. They're all worth a look – but that's a weekend killer – so I'd suggest these 3 are the ones I've thought about most since the event and are worth pulling to the front of your list:
Kevin Mann – nice guy did stuff, doing it again, loads of interesting stuff in here.
Jeremy Keith – content first. devices or viewports. I won't repeat his prefered title for the talk here, my mum might read it.
Corey Donohoe – tools tools tools – watch this and tell me you don't want to work at github!
