I'm looking at Building Social Apps with Stowe Boyd on sunday and design and usability .  

Monday, embracing the chaos and Micropublishing and tagging that works  

Tuesday Social Networks   and  Widgets and badges   and  api best practices  

and  revenue model (gotta pay the bills.......)

Wednesday   users at scale  or   measuring dos and don'ts   and   licensing user gen content    and   future of gaming  
 

I was hoping to go to this. Unfortunately, I have 2 projects that are on critical timelines
