Just when Entertainment Weekly seemed to be rolling the boulder back up the hill, Time Inc. told EW staff this morning that its publisher of the last two years, Ray Chelstowski, is leaving. Mr. Chelstowski informed Paul Caine, president and group publisher of the Style & Entertainment Group at Time Inc., that he has decided to leave EW, Mr. Caine said in a staff memo. No successor was named. "I will be communicating a plan shortly, and my door is open should you have any thoughts or suggestions," said Mr. Caine, himself a former EW publisher.
