Do experiments in new kinds of public media matter? Yes, according to Jeff Chester, the indefatigable dynamo who heads the Center for Digital Democracy (http://www.democraticmedia.org/). He has just issued a book-length manifesto for media reform, Digital Destiny: New Media and the Future of Democracy (The New Press). He takes on the powers that be in big media and government, and ends with a clarion call not only for media policy activism but for energetic and creative public media experiments on the broadband frontier: "As we look back a few years from now, much of our digital destiny may have been determined by how we have knitted together new projects that enhance civic discourse throughout what will be a ubiquitous electronic media system."
