Is there a Social Network For Coders? (GitHub Redux)

I do quite a bit of open source work. I do this because I feel a genuine sense of camaraderie between me and fellow contributors. The people I know through FOSS (and development in general) are smart, interesting, and always involved in events I want to know about and go to. Github does a pretty good (nope, I take that back, they do a GREAT) job at keeping me in touch with projects I care about. I value the updates that Github displays to me about the various projects I watch, but I'd ideally like to receive updates in a Facebook/G+ timeline-esque view on repositories and coders I'm 'watching'. Additionally, I'd like to have events, conferences and other gatherings where these coders I follow are going to be.

If I had something like this, Facebook and G+ would quickly become useless to me, as the people I really care about (in a professional context) are all on Github.

Are there any (grin and bear the buzzword here) 'social' layers on top of Github to enable more seamless social collaboration, as well as more genuine social interaction?
