An accurate summary from the homepage:
- freshmeat maintains the Web's largest index of Unix and cross-platform software, themes and related "eye-candy", and Palm OS software. Thousands of applications, which are preferably released under an open source license, are meticulously cataloged in the freshmeat database, and links to new applications are added daily. Each entry provides a description of the software, links to download it and to obtain more information, and a history of the project's releases, so readers can keep up-to-date on the latest developments.
- freshmeat is the first stop for Linux users hunting for the software they need for work or play. It is continuously updated with the latest developments from the "release early, release often" community. In addition to providing news on new releases, freshmeat offers a variety of original content on technical, political, and social aspects of software and programming, written by both freshmeat readers and Free Software luminaries. The comment board attached to each page serves as a home for spirited discussion, bug reports, and technical support. An essential resource for serious developers, freshmeat.net makes it possible to keep up on who's doing what, and what everyone else thinks of it.
In some ways, Freshmeat is more useful than Sourceforge, because generally projects announced on site actually have working code, as opposed to most Sourceforge projects that are lying in Alpha / planning limbo.
