The microblogging service Twitter enables users to publish short status updates of 280 characters or less. How does this change the way people communicate and interact? Which methods can be applied to analyze Twitter communication? How is Twitter used within the academic environment? The Department of Information Science in Düsseldorf investigates among others these questions.
