简介:[Publisher description] Amateur hour has arrived, and the audience is running the showIn a hard-hitting and provocative polemic, Silicon Valley insider and pundit Andrew Keen exposes the grave consequences of today鈥檚 new participatory Web 2.0 and reveals how it threatens our values, economy, and ultimately the very innovation and creativity that forms the fabric of American achievement. Our most valued cultural institutions, Keen warns -- our professional newspapers, magazines, music, and movies -- are being overtaken by an avalanche of amateur, user-generated free content. Advertising revenue is being siphoned off by free classified ads on sites like Craigslist; television networks are under attack from free user-generated programming on YouTube and the like; file-sharing and digital piracy have devastated the multibillion-dollar music business and threaten to undermine our movie industry. Worse, Keen claims, our 鈥渃ut-and-paste鈥?online culture -- in which intellectual property is freely swapped, downloaded, remashed, and aggregated -- threatens over 200 years of copyright protection and intellectual property rights, robbing artists, authors, journalists, musicians, editors, and producers of the fruits of their creative labors. In today鈥檚 self-broadcasting culture, where amateurism is celebrated and anyone with an opinion, however ill-informed, can publish a blog, post a video on YouTube, or change an entry on Wikipedia, the distinction between trained expert and uninformed amateur becomes dangerously blurred. When anonymous bloggers and videographers, unconstrained by professional standards or editorial filters, can alter the public debate and manipulate public opinion, truth becomes a commodity to be bought, sold, packaged, and reinvented. The very anonymity that the Web 2.0 offers calls into question the reliability of the information we receive and creates an environment in which sexual predators and identity thieves can roam free.
