Silicon Valley insider exposes the grave consequences of today's participatory Web 2.0 and reveals how it threatens our values and our economy. Keen claims that our most valued cultural institutions are being overtaken by an avalanche of amateur, user-generated free content and that our "cut-and-paste" online culture in which intellectual property is freely swapped, downloaded, remashed, and aggregated threatens over 200 years of copyright protection and intellectual property rights. Keen also warns that in today's self-broadcasting culture anyone with an opinion, however ill-informed and unconstrained by professional standards or editorial filters, can alter the public debate and manipulate public opinion.
