I like Github a lot, and SourceForge has definitely dropped the ball, but is anyone else tired of linkbait article titles? SourceForge has a ton of projects still. They didn't "lose" anymore than Github "won". Competition is trip not a destination. Nothing is for sure, and there's no reason why SourceForge can't improve their service and take back more of the market. Us in the tech world need to stop thinking that so…
That may be true, but I suspect that many, if not most, new projects aren't created on SourceForge anymore.
Most statistics are lies, of course, but Github currently has 2M repositories (including forks), as compared to Sourceforge's 300K projects. Seeing as how SF is over ten years old and Github was launched in 2008, that says to me that Github's where the real action is now.
