In that case, I'll support his conjecture by admitting that I didn't know that was possible. I'm a pretty average git user, if not actually using it slightly more than my peers (many of whom are only switching from subversion to git within the last 3-4 years). But the rate at which I become more proficient in git is extremely slow - you have to go out of your way to learn more about git most of the time. Maybe a GUI would help in that particular aspect, since I could see unknown options and experiment with them.
