Genres are not just forms. Genres are forms of life, ways of being. They are frames for social action. They are environments for learning. They are locations within which meaning is constructed. Genres shape the thoughts we form and the communications by which we interact. Genres are the familiar places we go to to create intelligible communicative action with each other and the guideposts we use to explore the unfamiliar.
~ Charles Bazerman, The Life of Genre, the Life in the Classrooms
