are widely adopted result in modified genre." In other work, they examine how the structuring of genre systems can be strategically used to organize interaction and influence response timing in electronic interchange. Natasha Artemeva has made similar observations based on an eight-year ethnographic survey that followed engineering students from academia and into the workplace environment. Although Artemeva observed that two of her subjects impacted the evolution of workplace genres when a kairotic moment presented itself (164) these former student's success in changing the workplace genre also depended on three individually acquired skills: 1) "cultural capital", 2) "domain content expertise", and 3) "agency in the rhetor's ability" to not only see when a kairotic moment presented itself, but "to also seize the opportunity" (167). Thomas Helscher is not as optimistic; he writes, the "rhetorical constitution of [a] discourse community operates as a counterweight to the process of community growth and change" (30) and argues that the "transformation of the fundamental generic conventions by which communities constitutes themselves...is paradigmatic of the process of social transformation" (32). The Problem of Genre Taxonomy The definition of genre from dictionary.com is "a class or category of artistic endeavor having a particular form, context, technique, or the like." Such a definition seems to invite a fixed taxonomy of enduring categories; however, understanding genre attribution as a process recognizes that genre categories are mutable and evolving, and thus are only quasi-stable. Genres, according to Daniel Chandler, create order to simplify the mass of available information. Creating categories promotes organization instead of chaos. Jane Feuer has divided ways to categorize genres into three different groups. The first is aesthetic. By using this method one can organize according to certain sets of characteristics, and so the overall work of the artist is not disparaged by generalization. The second classification method is ritual. Ritual uses its own culture to help classify. If one performs a ritual associated with a system of ritual, one can be said to be practicing as a member of that system. The common taxonomic method is ideological. This occurs most often in the marketing of texts, music, and movies. The effectiveness of this type of categorization can be measured by how well the public accepts these categories as valid. Amy J. Devitt focuses on the rhetorical approach to genre. Scholars generally recognize the restrictions placed on works that have been classified as a certain genre. However,
