Google's employee No. 20 has been named the CEO of Yahoo after an extended stay (13 years!) at the former company. She made a name for herself as head of location and local services at Google most recently, this including Google Maps and the managing of over 1,000 product managers. She's known for being responsible for the look and feel of the most famous Google web-based products still running strong, that being Google Images, Google News, Gmail in its newest iteration, and the white and completely unadorned homepage of Google for search.
