Example: Words for Friends by NewToys has 450 ratings. It's one of the most popular apps out there. It only has 13,500 sales? My iphone says Angry Birds has 55,000 ratings. This article would say that it, therefore, has less than 2 million sales, which seems low, to say the least. There are 190 million iPhones out there, and I bet more than 1% of them has Angry Birds.

Some of the comments note that Camera+ for instance has far less reviews than downloads that are out of whack with the 1-30 ratio, suggesting 1-100 might be more accurate.
