Yet another site for helping you find useful apps is appSpace, which says it has the world's most powerful recommendation engine. You can create an account and then specify the App Store categories that you tend to favor, your interests, your favorite apps, and your ratings for the apps that you like. Then it makes recommendations. This is an amazing site with a lot of potential, but so far of the recommendations it's given me, there's just one app I was glad to find. You can get a flavor of how this site works without having to register by using their cute gizmo on the front page. But you don't really get any utility unless you spend some time building your profile. The neat thing about this site is that it learns. It can track your interests "on the fly" and continue to refine your preferences.
