Sally Singer, the editor in chief of T: The New York Times Style Magazine, is leaving the pub at the end of the week, after a two-year stint marked by changes to "a more downtown vibe" with "hyper-intellectual" content -- as well as "complaints from the publishing side," and "clashes with Hugo Lindgren, editor of The New York Times Magazine," writes Amy Wicks. And "while some sources said Singer was asked to step down, others claim she chose to leave."
