This article draws on activity theory, politics of the artifact, and speech act theory to analyze how language practices and technology interplay in establishing the social relationships necessary for globally networked teams. Specifically, it uses activity theory to examine how linguistic infelicities and the politics of communication technologies interplay in virtual meetings, thereby demonstrating the importance of grounding professional communication instruction in social as well as technical effectiveness. That is, students must learn not only how to communicate technical concepts clearly and concisely and recognize cultural differences but also how to use language and choose media in ways that produce the social conditions necessary for effective collaboration in globally networked environments. The article analyzes two case studies—a workplace and a classroom—that illustrate how the mediating functions of language and the politics of technology intersect as mediating tools in globally networked activity systems. It then traces the implications of that intersection for professional communication theory and pedagogy.

Forest management plans, written by natural resource professionals for private landowners, provide a useful mechanism for analyzing documents concerned with communicating information about natural resources. The documents suggest that maintaining a sharp distinction between the professionals and the lay audience leads to stylistic and structural problems that hinder clear communication and mediate against collaborative decision making, even when such collaboration is the goal. This article offers specific mechanisms for overcoming these textual problems.
