iUseThis.com's new iPhone app ratings pages let you browse for software based on other user's recommendations. It's basically a Digg for iPhone apps. It offers new releases, new apps, top apps and reviews. Just started, the site is building up steam and users. When last I checked, it still had fewer than 200 apps listed. But given the growth of the iPhone application space, this site shows early promise should it manage to attract a large enough user base. Pop on by and see whether it suits your needs.
