Wow guys - cut them some slack. Making profit at a Startup Weekend is a gargantuan accomplishment, considering that most teams only get to the point of having a powerpoint demo / half finished prototype. Sure they didn't actually make that much compared to a real job in an established workplace, but this is still an awesome achievement.
I could pay $1 dollar to my team to subscribe to their service and call it "profit". But I do agree that most teams spin their wheels without actually executing much.
