DuoLingo, the massive collaboration project that Luis describes in the talk is not in beta (I am a beta tester) and it ROCKS! I am learning Spanish and have already translated parts of the web from Spanish to English :)
Enjoy this, one of my favorite TED Talks.
Any great ideas on additional massive online collaboration ideas? Any that target projects and project management? Add a comment!
