Writing can be used as a way to share an idea and start public discourse, however writing, like the writer, cannot get the job done alone. In order to begin public discourse, a topic needs to be explored/debated by multiple people. There need to be networks of people, also known as “communities of practice” who come together to discuss and promote an idea. Also, written works need to be supplemented by the form of media used; a written work will go no where if it is not publicized with the proper medium.
Writing classrooms need to teach public discourse writing in a different light. Composition is important, but it is not nearly 100% of the picture. Tone, persuasion and evidences are also key players in the success of a written piece, especially one that is meant to spark discussion in a civic arena.
