New York Post: Yahoo CEO Marissa Mayer may be looking to shuffle her executive suite. A source said there are rumors Yahoo’s successful mobile boss Adam Cahan is pressing for a bigger role. Cahan is about to have a baby with wife and former swimsuit model Anne Vyalitsyna. That bigger role for Cahan could come at the expense of marketing chief Kathy Savitt, who oversees Yahoo’s many media businesses, according to those in the know.
