reCaptcha Founder?s Language Learning Site Duolingo To Open To The Public On June 19

At TechCrunch Disrupt New York this morning, Luis von Ahn, the founder of the ambitious free language learning and text translation site Duolingo, announced that the site will come out of private beta on June 19. Duolingo was founded by reCaptcha founder Luis von Ahn in 2011. The site opened its private beta in late 2011 and currently focuses on teaching its users English, Spanish and German. Von Ahn, of course, is well-known for his work on reCaptcha, which Google acquired in 2009. As von Ahn noted today as Disrupt, more than 200 million captchas are now typed in every day. This insight led to the development of reCaptcha, which doesn't just help developers distinguish between bots and humans, but also helps to augment optical character recognition. About 10 percent of the world's population have now helped recognize at least one word. Now, with Duolingo, the team is pushing this idea forward.
