You made your own correction irrelevant when you stated that this happens on every platform, which is true. But that's how great apps appear on a platform, and how great niche apps come to be born on the platform, too. You can't say "there's an app for that" on a platform with 100 or even 1000 apps totally, even if you have the "top apps" in there.
