New York Post: Bloomberg’s new editor-in-chief, John Micklethwait, is shuffling management in an attempt to unite the far-flung news outfit and eliminate its notorious fiefdoms. In his first big move since taking the helm from Matt Winkler, Micklethwait tapped two top lieutenants — Reto Gregori on the news side and Josh Tyrangiel on the media side — to join him on a new management committee. All editors across the company’s various news operations will report to the committee, according to a memo.
