Today in WTF: "New York City schools chancellor Joel Klein is resigning to join News Corp., ending an eight-year reign at the helm of the nation's largest school system. In his place, Mayor Michael Bloomberg is expected to announce Cathie Black, chairwoman of Hearst Magazines. She would be the first woman charged with running New York City's 1,500 schools and more than one million students." Did I already say WTF? Because, you know, WTF?
