I think the term "social" is being overused here in the context of a startup, and was probably stuck in the tagline like many buzzwords, with an eye on marketing. The whole internet is social to a point. I think the term collaborative is more apt. The words that tended to jump out to me in the article were collaborative and commentary. He says "GitHub puts the social exchange at the very center", and I disagree. At the center with my view I see a strong tool to manage code that enables great collaboration. When you see a getting started tutorial with Github, the communication aspects are rarely mentioned. In the few projects I have seen getting popular there are usually external forces at work (i.e. Hacker News, Blogs, Large Corporate Support). It may be nice if Github was better at marketing your project. I suspect they may have to be better at it now and the product will undergo many changes in the coming year. That substantial portion of that 100m will likely all go to marketing efforts, not more engineers, which I think is a good thing.
