This is the first I've heard of external ratings affecting App Store ranks. Is this true?

Nobody knows exactly, but it sounds like true. We have seen many cases that the search results for "radio" contain apps which do no have "radio" in any places. The new Apple's algorithm indexes some external sources.

I believe Chomp was doing something like that, and if they are integrated into the app store as this article claims, it might be true.
