In examining the literature of conversational analysis and related techniques for describing language in use, it is my intention to discover what these techniques can tell us of how chatroom ‘talk’ works. In what ways is chatroom ‘talk’ similar to or different from natural conversation? Is it, even within its short history, one or many communicative forms? Are there common, “core” elements, present on all web-based chat sites? Are there specialist elements on specialist sites – and if so, is this limited to lexis, or does it extend to other elements of “texted talk”? Firstly I will explore the research on electronic chatrooms that is available, seeking existing insights into how texted talk works, and whether these can be extended by a fuller deployment of any of the language in use theories I have examined. Secondly I will draw on the current theories of conversational analysis to see whether it is possible, and useful, to establish a theoretical framework and methodological focus for examining how dialogue in electronic talk operates as a system of social meaning making within cyberculture.
