Okay since I'm just getting driveby downvotes, let me explain the source of my comment. The original comment said:

Well, Scott Chacon (#4 githubber I believe?) wrote the book to demystify Git. Of course, there is a certain irreducible complexity there, but I think Github has made a significant contribution there, so I don't think it's fair to level this criticism at them out of passing unfamiliarity.
