The idea is simple: 2Tangos is a service that brings people together to trade their knowledge. Users enter up to three things they are interested in learning and something they’d be willing to teach someone and their city. They connect using either one or more of their social networks and submit. Once a match is found both users are sent to a page that let them contact each other online and if they like, arrange a meet up.
