Luis von Ahn: Massive-scale online collaboration

http://www.ted.com After re-purposing CAPTCHA so each human-typed response helps digitize books, Luis von Ahn wondered how else to use small contributions by many on the Internet for greater good. At TEDxCMU, he shares how his ambitious new project, Duolingo, will help millions learn a new language while translating the Web quickly and accurately -- all for free.

I'm poor. I'm always told why I can't participate b/c of $. I just signed up for DuoLingo beta testing in Spanish. iMuchimas Gracias, Senor! What a great guy! I love how you think. Here's a big hug. Thank you.


With Duolingo you learn a language for free,
and simultaneously translate the Web.

Our private beta has started! Due to high demand, we are gradually inviting new users. If you haven’t done so, enter your email address to get early access
