What language does the Internet speak? All languages, of course, but English much more so than others.

Obviously, that’s a staggering prospect considering the sheer amount of content on the web. But according to Fox News, that’s the ambition behind Professor von Ahn’s new language-learning start-up Duolingo. Duolingo offers free language learning to everybody. Since the best way to learn is by doing, language learners on the service are simply assigned a few sentences to translate from the language they’re trying to learn into their native language. Each little snippet of text is from a real website. Duolingo then records the translation, compares it to other people’s translations of the same sentence and determines what the best translation for the sentence probably is. This is similar to the method used by Facebook to translate its website, though of course Duolingo’s project is much more ambitious in scope. Read more
