We have been working on apps.formeego.org for a while. The idea is to have a community driven Apps catalog for open source applications. Created by the people who also contributed to maemo.org Downloads (More than 100M downloads and counting!), many of the concepts born there were brought along.
This site includes a community driven QA part, where you can test apps and fill in a simple score card about the app. Once a certain amount of positive reports have been made, the app will automatically go to the stable Apps site. Apps will also go through some automated tests, so we can prevent broken applications from entering the repositories.
