OBSERVER STATUS: Another day, another departure at the New York Observer. After just seven months as general manager of digital, sources tell WWD that Harleen Kahlon is about to walk. She’s just the latest in a string of staffers that have headed for the exits as of late. “It’s literally a revolving door over there,” noted one source, who added that Kahlon’s departure stems from a number of disagreements she’s had about the direction of the digital business with president Christopher Barnes. This summer, it was reported that editor Kyle Pope was also at odds with Barnes. Kahlon’s exit comes in the midst of a redesign of the Web site and launch of new verticals. Kahlon declined to comment.
