How is the newness of new media constructed? Rejecting technological determinism, linguistic anthropologists understand that newness emerges when previous strategies for coordinating social interactions are challenged by a communicative channel. People experience a communicative channel as new when it enables people to circulate knowledge in new ways, to call forth new publics, to occupy new communicative roles, to engage in new forms of politics and control—in short, new social practices. Anthropologists studying media have been modifying the analytical tools that linguistic anthropologists have developed for language to uncover when and how media are understood to provide the possibilities for social change and when they are not. Taking coordination to be a vulnerable achievement, I address recent work that elaborates on the ways that linguistic anthropology segments communication to explore how a particular medium offers its own distinctive forms of authorship, circulation, storage, and audiences.
