Times columnist Michelle Slatalla and Business 2.0 editor Josh Quittner live together in wedded bliss, but according to an announcement in today's paper, they also "live in I.M. windows on each other's screens." That's why Michelle's "Online Shopper" column is now called "Cyberfamilias." From now on, she's going to write about how Information Superhighway has changed "almost every chapter of family life." Her inaugural column examines how sometimes kids search for medical information online, leading to humorous misdiagnoses like "strip throat" and "sick as hell anemia." Nothing, oddly, about homespun saccharine folksiness-borne diabetes. Also, some experts weigh in: "'Now more than ever, search engines are absolutely central to how people search,' said Susannah Fox, associate director at the Pew Internet and American Life Project." OH FOR PETE'S SAKE.
