This volume examines the language of microblogs drawing on the example of a group of eleven users who are united by their interest in ballet as a physical activity and an art form. The book reports on a three and a half year study which complemented a 20,000 word corpus of tweets with semi-structured interviews and participant observation. It deals with two main questions: how users exploit the linguistic resources at their disposal to build a certain identity, and how the community boundaries are performed discursively. The focus is on the speech acts of self-praise and complaint, and on the storytelling practices of microbloggers. The comprehensive treatment of the speech act theory and the social psychological approaches to self-disclosure provides a stepping stone to the analysis of identity work, for which the users draw on two distinctive interpretive repertoires - affiliative and self-promoting.
