It's hard to find 'organic' in a lot of things. As soon as there is money to be made, someone will figure out how to exploit that 'organic'. Ask Google with their search results. It's the basis of advertising--he with the most money gets his product in front of the most eyeballs.

That said, I would love some organic in the App Store as well, but every scenario I can imagine to accomplish it, I can also imagine how to exploit.
