Karmacoin Takes On Virtual Currency Tipping Via Twitter

Los Angeles-based Karmacoin has rolled out a new, virtual currency, and a service to let users "tip" and reward other users using Twitter. According to the company, its new service lets anyone send other people its digital currency on Twitter, with the idea that people can pay for micro content and make micro donations using the popular social networking and communications service. Karmacoin explained that it is a digital currency like Bitcoin, with a specific aim at the "good economy". Currently, users can only buy Karmacoin by exchanging their existing Bitcoins into the currency through a Bitcoin exchange.
