[Air-l] Turn-taking in email

Hi Everyone, I'd like to leverage the recent and informative discussion on hedges to ask a related conversation-analysis question. Can anyone point me to discussions of turn-taking online, particularly via email? I know of Marc Smith's work with newsgroups and 'answer-people', Loch et. al.'s paper comparing online and offline turntaking and Rebecca Warner's work, but that's about it. Any input is appreciated, Many thanks, BERNiE Bernie Hogan PhD Student Department of Sociology NetLab, Knowledge Media Design Institute University of Toronto --
