Go ahead and bellyache about blogs. But you cannot afford to close your eyes to them, because they're simply the most explosive outbreak in the information world since the Internet itself. And they're going to shake up just about every business -- including yours. It doesn't matter whether you're shipping paper clips, pork bellies, or videos of Britney in a bikini, blogs are a phenomenon that you cannot ignore, postpone, or delegate. Given the changes barreling down upon us, blogs are not a business elective. They're a prerequisite.
