Abigail Lambke extends Collin Gifford Brooke’s (2009) theory of rhetorical canons as an ecology, in which choices in one canon influence others as in a dynamic ecological model, and applies that to the practice, process, composition, and reception of podcasting–a form that can be considered both a static text and an interface. Lambke concludes that we might be in the age of secondary orality, but text, print, visuals, graphic narratives remain central to how we can think about and process the world.
