I use github every day for professional and personal projects, and typically like what they've done, but Sourceforge.net was the github of the early 2000's, where almost every developer had an account and where you could get free development and distribution tools for your project. Look at what it is now (or was before it was re-opened a few months ago.) People's open source projects were being leveraged to push malware on unsuspecting users. We might not think it's so great to have all this centralized code storage in a few more years when the new hotness replaces github and everyone's zombie products are being used maliciously again.
