Among the ways that digital media has transformed political activism, the most remarkable is not that new media allows disorganized masses to speak, but that it enables organized activist groups to listen. Beneath the waves of e-petitions, "likes," and hashtags lies a sea of data - a newly quantified form of supporter sentiment - and advocacy organizations can now utilize new tools to measure this data to make decisions and shape campaigns. In this book, David Karpf discusses the power and potential of this new "analytic activism," exploring the organizational and media logics that determine how digital inputs shape the choices that political campaigners make. He provides the first careful analysis of how organizations like Change.org and Upworthy.com influence the types of political narratives that dominate our Facebook newsfeeds and Twitter timelines, and how MoveOn.org and its "netroots" peers use analytics to listen more effectively to their members and supporters. As well, he identifies the boundaries that define the scope of this new style of organized citizen engagement. But also raising a note of caution, Karpf identifies the dangers and limitations in putting too much faith in these new forms of organized listening.

In this book Michael Heim provides the first consistent philosophical basis for critically evaluating the impact of word processing on our use of and ideas about language. This edition includes a new foreword by David Gelernter, a new preface by the author, and an updated bibliography. "Not only important but seminal, on the cutting-edge, furrowing new conceptual territory."-Walter J. Ong, S.J. "A philosopher ponders how the word processor has affected language use and our ideas about it. Heim shrewdly updates a school of thought, associated with such thinkers as Walter Ong, that maintains all changes in writing technology tend to change the way we perceive the world. His argument that word processing leads to fragmented thinking should be addressed and debated."-Carlin Romano, Philadelphia Inquirer "The arguments range over all of Western philosophy (and some Eastern as well), from the ancient Greeks to contemporary phenomenology. . . . Everyone who has used a word processor will find much to think about in Heim's ideas."-David Weinberger, Byte "Fascinating, clear, and well-done . . . stimulating and challenging."-Don Ihde, Philosophy and Rhetoric
