Fair enough, but there is still a hosted solution, it's just hosted email instead :) I know Linux used that approach, which is seemingly ironic since Linus made git, and previously used BitKeeper. There seemed to be some problem that emailing patches to a mailing list wasn't solving to motivate the invention of git.

You can email git patches though (which is essentially what pull requests are, really, just using a different interface)
