The Ohloh Open Source Directory is a pretty cool collection of over 3000 OSS projects, rated and ranked by popularity, along with contributor information, code and other useful bits and pieces.

 Ohloh is a resource for open source intelligence on thousands of open source projects. Ohloh collects software metrics from a variety of sources including the project’s source code and the software development infrastructure used by the project’s development team.
