I may be blind to the learning problems since I know git already. But isn't it pretty hard to mess up a git repo if all you do is add+commit? (maybe combined into a "save" button in some UI) Then, asking someone who knows better when you want to do anything more complicated.
To me, just being able to save versions and look at them later (like saves in a video game) is such a huge boon that any of the more complicated features don't even need to be touched for git to be worth it.
