[Air-l] memetics & vle's

Hello, I'm hunting around for work by anyone who's taken a critical look at the idea of memetics in relation to the learning that goes on in virtual environments. (and i'm conceiving of virtual learning environments rather broadly, although some obvious examples might be weblogs, mailinglists, etc.) even a brief mention in passing in a paragraph would be of interest. Thanks, Katherine Parrish OISE/University of Toronto
