I'd be willing to bet that this gets awarded to someone that wasn't even trying. "Little Timmy downloads Elmo teaches numbers and wins dad $10k credit to the iTunes store."
Yeah, the last winner of an app countdown was downloading that Paper Glider(or something with a paper airplane and brown wood background as an icon, where you steer a paper airplane in a 3D environment) app. It was free...
Yeah, I've been counting on it being wrong, each day for the last couple days I've downloaded somethng new, the chance of winning is super low, but atleast I have a chance that way, and I don't have to waste all my time stuffing the box with votes.
