Praise for Republic.com: "Republic.com raises important and troubling questions about the effects of the Internet on a democratic society."--Stephen Labaton, New York Times Book Review "In this follow up to Republic.com, his first appraisal of technology's effect on public discourse, University of Chicago Law School professor Sunstein waxes pessimistic about today's 'nightmare' of limitless news and information options--and, more significantly, the limitless options for avoiding it...This perceptive volume effectively illuminates the contradictory impulses at the heart of the citizen-consumer."--Publishers Weekly "Republic.com 2.0 is a refreshing counter to overly optimistic perspectives on the internet and democracy, and Sunstein turns Utopian visions of the internet enabling individuals to gain access to exactly what they are interested in--'The Daily Me'--into a critical assessment of its potential for undermining democratic discourse."--William Dutton, Times Higher Education "[Sunstein] argues persuasively that the fragmented market for communications, which may cater to the desires of consumers, is harmful to the development of informed and moderate citizens because it limits or even makes impossible exposure to unsolicited, diverse, and occasionally unwelcome views, all of which are necessary in democracies...This book is a splendid antidote to the views of the utopian populists who equate democracy with information choice provided over the internet."--B. Cooper, Choice Praise for Republic.com: "Cass Sunstein sounds a timely warning in this concise, sophisticated account of the rise of the internet culture. He argues that it is our very ability to wrap ourselves in our own tastes, views, and prejudices with the aid of technology that constitutes a real threat to the traditional democratic values."--Peter Aspden, Financial Times "By its nature, Sunstein argues, the Web fragments us into ever-smaller niches. In this way, for all of its incredible, information-sharing connectivity, the Web can be isolating, especially when groups begin to 'echo chamber' and talk only to themselves...To my mind, Sunstein has always been lucid and valuable on this topic. But despite the Web's culture-changing successes--wiring up the economy, influencing presidential campaigns--many Web advocates and bloggers still act as though they're threatened. When they're not acting triumphalist, that is. Even the lightest guidelines, in short, will be resented, particularly when our confusion of free markets with free speech has proved so profitable."--Jerome Weeks, San Francisco Chronicle "This book, now in a substantially revised edition, remains the most effective public work depicting this debate and urging on us this proper vision of a reasonable freedom."--Charles Mathewes, Virginia Quarterly Review "Lucid and thought-provoking, Republic.com 2.0 raises important concerns... Carefully argued, well balanced, and accessible to a general audience."--Elisabeth Herschbach, Metapsychology Online Reviews

Republic.com enraged many because it asked a set of uncomfortable questions that few had a way of answering. In this beautifully revised edition, Sunstein continues to press these difficult questions, not as an attack on new technologies but as a challenge to make them make democracy work. This is a compelling if sober set of questions from America's foremost legal scholar. -- Lawrence Lessig, Stanford University
