Wow, thanks for the insight. It's sort of crazy to think about how big GitHub has become, and how much Microsoft paid for it, but of course it wasn't the first product in the space at all. Right time, right place, right features, I guess, and maybe Google Code was missing a bit of each of those.

As I recall, GitHub popularized (maybe even invented) the pull request. That's what enabled open source to take off - being able to send patches to (or even fork) other projects with minimal friction.
