Soukup's study focuses upon two chatrooms - one sports-related and male-dominated, and the other female-based and female-dominated. His results support the ideas cited by Tannen and others in linguistic studies of discourse, in that the male chatters were more aggressive, argumentative, and power-seeking than the female chatters. It's unclear to me whether the results can be viewed as reliable or representative, since there may be an inherent social context to a sports-related chatroom/bulletin board that goes above and beyond being merely a male-dominant community. For example, Soukup cites the fact that the sports-related chatroom essentially turned into a locker room replete with profane and sexist language, including sexual put-downs and challenges between male chatters. He goes on to note that when male chatters entered the chatroom of the female-based community, that there was frequent inappropriate behavior such that groups of male chatters would take-over the room with sexist remarks or propositioning of the female members.
