"I have to say that I'm pretty blown away by how much bigger the total $ raised was this year, especially when you exclude the HP contribution... And your note about increasing the # of participants is interesting, too...it seems like the Meetup incentive really drove that metric. Really cool idea for layering more game dynamics on top of the Challenge. Next year we should do something wacky with the DChoose API + the SMC! We'll have to have a brainstorm on that one ;-)" - Ethan Bauley
