This week, we learned of two top magazine staffers, one publisher and one editor-in-chief, leaving their posts after just a few months on the job.

First came word that Susan Reed is leaving her spot as editor-in-chief at O, The Oprah Magazine after less than a year at the helm of the Hearst pub. Before joining O, Reed served as the editor-in-chief at Golf for Women for more than six years. She will be replaced by Time Inc.'s Susan Casey.

Also this week, the New York Post reported that Francis Farrell will be leaving the publisher slot at Men's Journal after less than six months. Farrell formerly worked as publisher National Geographic Traveler and joined the men's magazine in October 2008. Farrell will be replaced by Matt Mastrangelo, the Post said.

The Post also reported that American Media, which publishes Star and National Enquirer has lost its CFO Dean Durbin after only a year and a half -- not quite as short a stint as the others but a quick turnaround nonetheless.
