Here is one thing that happened to me after using Duolingo every day, multiple times a day for more than a year. I became extremely good at it. Throw any language at me, I'll complete it in record time. Sometimes I played it without even the sound on.

Do I speak any of the languages in the game? Hardly. This realization came to me after I completed the Japanese class and my sister asked me to count to ten. I knew all the numbers, their symbols, and the placement in a sentence. But I could not count to ten.

Duolingo is a game before being a learning tool. It is fun to use and I'm almost jealous that they are going to IPO. But it's kinda like farmville. You become good at the game, but you probably won't become a farmer after playing.
