GitHub is not your CV, but I think it should be on your CV. If you're an artist when you interview they usually want to see a portfolio of your work, GitHub is a pretty handy way to portfolio code for others to view.
There's many good things about it, and reasonably few downsides to trade off against, but overall if you've got a GitHub I'd be more interested in seeing that than knowing what grades you got at school 15 years ago.
