Well, what a novel and innovative concept this is! Learn a language of your own choice and help, as a native speaker of your own language, to translate the web. I already do this as part of my FaceBook experience. I help with the language development on FaceBook because I signed up for it. DuoLingo means you can learn French but how motivating is that , that you can then use your mother tongue skills to help others learn your language? I like this world and the way the internet allows us to work together as a planet to facilitate good things for ourselves. I also know form my Facebook experience that it really is a good way to improve , enhance and share your language skills.
