Clayton let me know about a very helpful website, AppReview, that is also available as an iPhone application (iTunes link). The AppReview folks have currently conducted hands-on evaluations of over 17,000 of the 32,000+ applications and offers one of the largest databases of user reviews. There are tabs for the Best, Better, and Good apps where each list can be sorted by name, price, and date. You can view apps on What's New, Categories, and Recommendations pages.
You can view application reviews by category and even see what applications have earned a thumbs-down rating. There are an overwhelming number of games currently in their database (6,837), followed by books (3,912) and then entertainment apps (3,324).
This site has proven to be helpful in sorting through the App Store and I look for continued refinement in iTunes to help users find apps that help them out.
