Quite interesting to see that Google released it on Github rather than using Google code hosting like they've done in the past [1].

Github is a much more social and connected platform than google code. Easier to find and fork projects and more of a neutral venue where different technologies can co-exist. Another interesting thing is that a lot of the google developers are on stackoverflow, which isn't google centric, but is very accessible as well.

Most of Google's client libraries and sample projects have been moving to GitHub over the last year.

Google is moving more and more code to Github (at least for public facing projects). Google code is pretty much a corporate code repo from one decade ago.
