Two questions:
(1) Do app updates count towards this contest?
(2) Is this contest rigged?
It's always a popular app. It's never some random app. I wonder if Apple would allow an app that is rated 1-2 stars to become "The 25 Billionth App" just because it was downloaded by coincidence by someone who was experimenting with the App Store.
It's probably a legit contest, but I'm always shocked it's apps that are popular or advertised already in a positive light. People do download bad apps, and I'm waiting to see a bad app hit the spotlight to merit some authenticity even if it would be bad publicity.
Everyone should download FREE bad apps on the next contest during the final hours.
