Is anyone else confused by the premise of startup weekend? It sounds like a fun idea, but the whole concept seems a little silly to me.
I really loved the part where the heroic manager talks the Rails programmers out of embarking on an entertaining game of competitive hacking in order to keep the entire, gigantic 70-person team focused on... waiting around. Imagine the consequences if he had failed!
That would bring a bunch of people together without violating the "small startup" principle. Also, completion between the teams would help with motivation.
