Just found this reference to the 06/09/2007 Washington Post article by — Joel Garreau [thanks to AfterCyberPunk]:
‘Gibson says: “One of the biggest technologically driven changes in my writing is the awareness that every text today has a kind of spectral quasi-hypertext surrounding it.” It is “all of the Googled information that found its way into the book but which isn’t available to the reader as a literal hypertext unless you’re willing to be the animator of the hypertext process” and Google each term that’s distinctive and new.
“It’s curious. When I published ‘Pattern Recognition’” — his previous book, which was also set in the recent past and achieved mainstream success — “within a few months there was someone who started a Web site. People were compiling Googled references to every term and every place in the book. It has photographs of just about every locale in the book — a massive site that was compiled by volunteer effort. But it took a couple of years to come together. With ‘Spook Country,’ the same thing was up on the Web before the book was published.” Somebody got an advance reader copy, and instantly put up a site for his fictional Node magazine.’
