A great new concept in language learning is coming in June. Currently Spanish and German will be offered with others to follow. There are to videos below. The first explains about CAPTCHA, reCAPTCHA and introduces Duolingo. When Luis explained about reCAPTCHA I felt better about having to use it.
"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."
