I'm working with a grad student who is interested in studying communication practices/norms as barriers to inclusion in virtual communities. While this topic abutts my own interests, it is not my area of expertise. I've already turned him toward Nancy Baym's _Tune In, Log On_ and Lynn Cherny's _Conversation and Community_, as well as some more foundational work in socio-linguistics, speech communities and ethnography of speaking (e.g. Hymes, Gumperz, Philipsen). I'd appreciate any suggestions of relevant work that might inform his research. Scholarship from a critical/rhetorical perspective is particularly desirable. Thanks and best regards, Gerald Gerald Voorhees, PhD Assistant Professor of Media and Cultural Studies Speech Communication/New Media Communication Oregon State University
