One thing that Apple has that Google doesn't seem to have is an affiliate program. Affiliates get %5 of app sales (or other iTunes sales) by driving traffic to the store. This provides a funding mechanism to incentivize people to make discovery tools. I'm kinda impressed with the number of third party discovery tools for android, but I think that ecosystem would be more robust, and less of the burden on google, if they provided a monetization method for good app discovery. Apple just partnered with LinkShare and other providers of the service. Seems Google could do the same thing.
