"In this book of social commentary, David Weinberger takes us beyond the hype, revealing what is truly revolutionary about this new medium. Just as Marshall McLuhan forever altered our view of broadcast media, Weinberger shows that the Web is transforming not only social institutions but also bedrock concepts of our world such as space, time, self, knowledge - even reality itself.". "The Web would be important enough if it hooked up our species on a global scale. But, Weinberger argues, it is doing much more than that. Unlike previous technologies such as the phone or fax, the Web is a permanent public space that gathers value every time someone posts a Web page, responds on a discussion board, or replies to a mail list. More and more of our lives together are being lived in this new, second world that intersects the real world in ways we have only begun to understand."--BOOK JACKET.
