It's all the rage in English at the moment. Have a couple of friends about to publish a textbook on the subject. It's the response of English to the incredible transformation in writing that has taken place as a result of the internet. Think of the class as a class on how the printing press is changing writing taken in 1460. Should be quite interesting actually. In fact, OD may turn out to be a central feature of the class. We're all writing here and we're probably writing a heck of a lot more on a wider range of topics than any of use did 15 yrs ago. I suggest you focus your work on internet forums and their open discussions as the rhetorical space replacing the pub and the pamphlet. We're at the center of the modern dialectic.
