An extraordinary public slap, rarely seen in the genteel world of magazine publisher Time Inc.: Fortune appears to have momentarily taken executive editor Josh Quittner's Techland blog away from him and handed it to rival tech writer David Kirkpatrick. Quittner's recent blog rant about Facebook's Beacon was wrongheaded enough, but entirely undeserving of this humiliation — republishing, duplicatively, a Fortune.com column by Kirkpatrick in Quittner's blog. Kirkpatrick, left, declared that Quittner, right, had been "silenced" on the Facebook issue. He went on to tear apart, at length, Quittner's argument. All the more shaming, because Kirkpatrick is — how to put this gently? — a laughingstock among his colleagues.
