Google has hired Udi Manber, the head of Amazon's A9 online search unit, the Associated Press reported on Tuesday. Manber will be a vice president of engineering at Google, according to Google spokeswoman Lynn Fox. She declined to provide more details. This is just the latest in a string of controversial Google hirings, including employees from rivals. Even more high notworthy has been Google's hiring of former Microsoft employee Kai-Fu Lee, which sparked a lawsuit that has since been settled, and Internet pioneer Vint Cerf.
