LiveMocha is a social web site, like Mixi or Facebook, or MySpace, but better. This social web site is all about language learning and language exchange. People teach each other or simply interact in foreign languages. The New York Times has taken notice (look at the quote on their home page). I ask my students to sign up and use LiveMocha as part of my Computer Literacy Class. They seem to really like it. You can get points by teaching other people, or helping to create materials in your own language, and use those points for learning. A whole new economics of teaching is being created here.
