Hi, Luis! How would you describe the core teaching philosophy at Duolingo? There's a lot of debate in the discussions about whether Duo tries to teach through immersion and whether or not it's designed to teach you in the way a child would learn. (I know where I stand on this, but I'd love to hear your authoritative viewpoint.)

You mentioned in a TED talk that Duo would seek revenue by marketing crowdsourced translations to companies. How have companies responded to this idea so far, and is it as viable (or more viable) than you expected? Have you had to adjust your business plan accordingly?
