This. I'm a big fan of Github, but it bothers me that this single service is the centerpiece of most OSS projects. We see it every time Github goes down and virtually nobody can be productive anymore.
I hope to see a version control system on top of IPFS some day.
Ironically, git itself is decentralized. More effort should go into decentralized software architectures, especially in the current security climate where having a central point of failure is like having a virtual bull's eye for bad guys. There's no reason you couldn't have a decentralized issue tracker for example.
