This doesn't seem to explain how you make money - it's an explanation of how Duolingo works.

Are there any plans for reducing the price of the Type Cover? It's pretty expensive...

What's Duolingo's revenue model?

As I'm typing this I'm in the middle of a Duolingo lesson, and I'm hoping you guys can afford to continue to teach me for free. Also, if you charged me for the Duolingo for Windows Phone app, I'd have gladly bought it.
