For me at least, I presume that the social network comes from the people you talk to, with whatever medium you use, when one is involved in a project, wherever the code is hosted. I never saw GitHub to be special. I got work from meetups, from participating on mailing lists, etc. but not GitHub. There is no tight link to it, but I can presume for myself that can be that case for a particular project. But - to each their own on this matter.
