In Rhetoric Online: Persuasion and Politics on the World Wide Web, Barbara Warnick seeks to map new research agendas for rhetorical understanding and criticism of online public discourse. Warnick offers a well-grounded melding of media theory and rhetorical criticism, thus enlivening both fields. She also seeks to remedy what she contends is an oversight in rhetorical scholarship, namely a lack of detailed case study examinations of public discourse in Web environments.
As I explain below in my overviews of individual chapters, Rhetoric Online is an important and useful book, one especially valuable to scholars who examine the interplay of rhetoric and technology, such as readers of Kairos.
