What a coincidence: Sheryl Sandberg seized responsibility for PR when she left Google to join Facebook as COO last month. Like clockwork, there's an organized publicity campaign to buff the executive's image. Take this sycophantic utterance from Christopher Cox, Sandberg's head of human resources: "It was like Sheryl came and kicked everybody in the ass and said this is going to be hard. And then gave everybody a hug." That's what Cox told Fortune, at any rate. He privately confessed to colleagues that he "felt sick after saying that." Sheryl, you should give Cox a raise: An HR chief who's so ready to fib for you is golden.
