O'Reilly's insistence on making everyone use git (including non-programmers) seems a bit nuts to me.
It's nuts. Git is hard enough to learn for people who know the internals of how computers work. Making people who would rather be drawing artwork learn how to use git seems really crazy to me. Hearing the coping stories from non-technical people using git is very sad.
I've seen designers use version control with things like: filename.FINALE.jpg filename.Last Finale.jpg filename.Approved Finale.jpg etc.
Certainly its worth the half hour getting your head around the basics of SourceTree than that...
