We’ve been working on this paper for a few years now, having presented our initial findings at several MOOD events. I’m very pleased to see it in press. It builds on the earlier paper co-written by the MOOD organizing team and sets the stage for researchers who want to apply conversation analysis methods to various forms of online talk. We focused specifically on text-based talk, so a logical extension of this work would be to explore how CA is being used in multi-modal environments.
