Thanks for pointing that out. I did not know such a service existed. Having said that, we are planning to concentrate on a smaller segment, most probably games. This will help with the number of reviewers we can attract, retain and the amount of time they spend with the app/game.

You also bring up an excellent point of providing free publicity - we hadn't given that serious thought. We could profile each app that is submitted on our site and quote user reviews, but the challenge would be to make the site/blog an attractive destination for real Android market users.
