Time Inc., my former employer, goes through spasmodic bouts of reorganizations, switching between centralization and decentralization as frequently as its magazines redesign themselves. CEO Ann Moore's latest reshuffle, which is costing 600 jobs, has created three new groups , each with its own head of digital operations. That seems to have put Ned Desmond, the head of Time Inc. Interactive, out of a job. (Desmond is better remembered in the Valley as the former president and editor of Time Inc.'s Business 2.0 , where I used to work.)Not that it was ever very clear to Time Incers what his division did: Until last year, it didn't even run Time Inc.'s Web servers, and several of Time Inc.'s more successful websites, like CNNMoney.com and SI.com, have made a point of staying outside of Desmond's reach.
