Starbucks is using Twitter

The coffee giant, Starbucks, is one of many U.S. companies using Twitter. Twitter is a trendy micro-blogging platform which many view as a speedy marketing tool. "What are you doing?" is the simple question that Twitter users answer in short posts or "Tweets" from their cell phones and desktops. Twitter users can respond to posts, and discussion threads are created allowing companies to monitor what customers are saying about them. Companies can also release news in Tweets. Hubstop estimates that 5,000 to 10,000 new Twitter accounts are opened each day.
