This is a great point. But before you can make people work at understanding something, you have to make them realize that they have a stake in trying to learn.

I don't think everyone (and certainly not myself) was able to understand the value of Git at first glance and decide to invest time and effort into learning about its inner workings.

Normal Code School courses and Ruby Monk challenges are made for people who already have somewhat of a vested interested in learning. Something that pushes them to challenge themselves beyond a simple demo/interactive tutorial. People like that are (sadly) a limited subset, we're trying to broaden that.
