I feel that everyone should take this course just so we know that we're all on the same page when it comes to conversation structure and etiquette. Much of the information was basic and familiar, but Curzan nonetheless finds a way to make it entertaining and insightful. This course isn't necessary if you feel that you are already pretty good at conversation and how to negotiate one, but it does bring interesting linguistic ideas to bear on conversation structure. I do feel an urge to evangelize about how the conversation floor and backchanneling work after listening. Good, short course.
