Interesting redesign. In 2009 they did a previous redesign, which Chris Wanstrath from GitHub critiqued at RailsConf http://www.youtube.com/watch?v=JUUvq48Gb3w (Around 17:45). It looks like they've improved since then, but I couldn't even create a project, the system gave me a 400. Also, the site seems really slow, but possibly that's because they just relaunched.

While they get a lot of flak because they have supposedly lost to GitHub, I'll admit that far more people have heard of SourceForge compared the GitHub, and I must applaud their willingness to at least attempt a major redesign.
