Rosetta Stone and Pimsleur won't be happy about von Ahn's first goal: making learning a language free and easy. And Translations.com won't like the second: free translation services for individuals and companies.
Luis von Ahn, the crowdsourcing pioneer who developed reCAPTCHA, has come up with the perfect crowdsourcing project. His new company Duolingo aims teaches people how to speak languages by reading, writing, speaking and listening to translations of Web content. The byproduct of that activity, if all goes well, will be a fast and accurate human-powered translation engine.
