I agree with other comments that competing in a global economy requires a great app, but what it also requires is running the business that created that app like a real company. That means more than just building a great app.

Developers that understand this are able to make a living on the app store while those that wait for the store to magically make their app successful don't.

As the VC markets cool down we'll those companies that didn't build a company around their apps fail more.

I personally think what's happening now is the market maturing. In the long term this will lead to more stability for those who know how to compete.
