Wakoopa – Software Gone Social
http://www.wakoopa.com/

With Wakoopa you know what software you’ve been using, and how long you’ve been using it. But you also get updated when a new version comes out, or somebody wrties a review about your software. Wakoopa allows you to share your software usage and your opinions about software. Just invite your friends to view your profile, or put a widget on your own site.
