The GitHub fallacy in action yet again. Normally you would expect developers and people immersed into technical culture (this excludes 9-to-5 enterprise developers) to be quite skeptical of mainstream solutions and not accept a one true medium. Yet in the case of where they host their software projects, the hipsters have elected a solid winner: GitHub. Ignore all other Git-based services like BitBucket and Gitorious, or... heaven forbid, version control that isn't Git.
Carry on.
