Programming language Go, initially developed at Google, has just moved to GitHub.

Go, a language loosely based on C that is used in some of Google’s production systems, was hosted on GitHub competitor Mercurial until Thursday. Rob Pike, Google engineer and lead designer and contributor at Go, explained the decision on Go’s message board.
