Obviously with $100M cash, big things will be coming for GitHub. It is hard to imagine that they haven't thought about other collaborative communities.
Will big things be coming? I hope they use that money to grow on the core things they are good at rather than try to capture markets which don't need capturing.
They have a unique position in that almost 100% of its users can only say good things about it (bar maybe Torvalds).
I want small things from Github, glorious small things.
