I had a lot of fun at ecommerce hackathon. I've thought about what makes for a great hackathon, and, credit where credit is due, it comes down to the organizer. Alex organizes the best hackathons I've ever been to in NYC, and I've been to them all. Photo hack days last year were several notches above everything else, and now that Alex is at Dwolla, we're seeing the same thing in ecommerce themed hackathons. Great job, Alex!
