It's official: Rebecca Dana is leaving the Jared Kusher compound. The television industry scribe makes true those rumors about the New York Observer lass leaving for the New York Times' Business Day, where she'll reunite with former Washington Post colleague Michael Barbaro and fight David Carr for stories. Her exit leaves Kusher with just Michael Calderone and Spencer Morgan to continue dialoguing about the media bubble and its offshoots. Which is definitely a sign of progress, 'cause there really were too many women with regular bylines at the Observer.
