Not necessarily the case. It depends what your market is. The early adopter App Store audience is quite diverse, and not at all like the tech early adopter crowd.
In terms of growth, being on the US front page is absolutely huge, so there's lots of politics about getting on there. If you have connections, it's a lot easier to get up there.
That doesn't sound fair. But it doesn't surprise me. Most of it is a waste of my time.
I find my apps in the browser from people or companies talking about them. Then I go to the app store and do a search for it.
Getting your website covered by TechCrunch will bring in a few hundred, maybe thousand, "one time" users. Front page of the App Store can be 50K over a week.
Good apps will rise to the top. That is what they call a market.
