Massive-scale online collaboration

The question that motivates my research is, if we can put a man on the Moon with 100,000 [people], what can we do with 100 million? — Luis von Ahn

Synopsis

After re-purposing a computer challenge-response test so that each human-typed response helps digitise books, Luis von Ahn wondered how else to use small contributions by many on the Internet for the greater good. His ambitious new project, Duolingo, will help millions learn a new language while translating the Web quickly and accurately – all for free. Talk recorded 3 April 2012.
