This is more of a thought then nothing else, but I wonder just how useful learning about GitHub and collaborating via GitHub is, especially considering how much time it takes. I know in my own experience and my own department, collaboration on projects doesn't happen too often as everyone's research is so diverse. Using Github as a backup is a good idea though. Has teaching branching ever been done before? That is something I see people within medical/health science use more often.
