I really like this idea. I consult Stack Overflow or the git man pages frequently enough to make it annoying, but infrequently enough to have the appropriate magic incantations become instinct.

However, if I am going to distance myself from the bare metal of git, why not go all the way and use something like GitHub for Mac? That seems like a true "Git for humans". I love working from the command line as much as possible though, so I will watch this closely to see if it becomes widely adopted.
