How’s this for a possible 2-for-1 deal. Microsoft should finally acquire Yahoo (after an aborted first attempt) and get an enormous prize in the process in Marissa Mayer. During her short tenure at the company, the former Google exec has managed to edge out Google in U.S. Web traffic. Mayer’s famous attention to detail has played a role in this rebound, as she has pushed her charges to improve the user experience across multiple services. Although Mayer caused some controversy by coming down on working remotely, the stock is up approximately 75 percent since she took over. It’s hard to argue with those results.
