What? Yes it will. More recent links from people will give it more page rank score. If it's a new algorithm that helps find cheaper tickets and beats out the major competitors, for example, it'll get tons of links really quick from blogs talking about it.

Ask the developers in the appstore whats more important, interesting content or a position in the top 5.

I don't think you get how this works.

Right..so if e-commerce businesses just hired smart people to build algorithms and hope for viral effects they will rank high. You make it sound so easy.. unfortunately I would say this is unrealistic in most cases. In a realistic world you have to admit that it is very hard for businesses in saturated markets to just add "interesting content". Having a budget for online marketing, including seo, adds measurable ways to achieve sales. Spending a fortune on technology might be out of proportion compared to your business size. Having a sale, good customer service, coupon codes will give the same kind of buzz in the blog scene around your product. It is still part of the puzzle and you need more than one part to solve the puzzle.

"I don't think you get how this works."

Then tell me whats wrong with my statement about the appstore. Just telling someone he doesn't get it has no added value. You can make your statement more useful by, for example, adding some links to blog posts from people who write about the process of gaining a steady income stream using interesting content.
