The coauthor of the no-more-business-as-usual blockbuster The Cluetrain Manifesto--which basically told Net-age marketers to stop talking at their markets and start conversing with them--follows up with a book that's more a highly entertaining, nimbly erudite screed against our current mass-market, mass-media culture than it is a recipe book for e-commerce marketing success in the post-cyberboom era. Writing in a paler imitation of the profanely irreverent, freely associative "gonzo" journalism style pioneered by his obvious idol Hunter S. Thompson, Locke starts with the by-now-familiar idea that old-style mass-marketing "broadcast" advertising just won't work on the Web. Indeed, he says, conventional print-ad tactics as embodied online by banners and pop-ups might actually generate more ill will than sales, and that's why companies must use the Web to somehow enjoin their products and services to the quirky niche interests of the gazillion individual cybercommunities (or "micromarkets") whose greatest advantage for marketers is how freely and speedily their members talk among themselves, touting a brand when and if it's truly deserved.
