What is Common Interest

Online communities such as newsgroups and mailinglists are constructed around a common interest and a shared set of norms that regulates communication. These communicative norms can be studied either by observing the communicative practice of the participants or by analyzing what group members say about correct and appropriate behavior in that community (referred to as metacommunication). This chapter investigates the differing roles of metacommunication in online communities such as mailinglists, newsgroups, and online forums with an aim to provide a basis for the future analysis of group behavior. It explains how members are instructed about correct and appropriate communicative behavior, and how various evaluative means of metacommunication can negotiate these norms and contribute toward community building.
