Marissa Mayer's Blind Spot
Call it high tech and high touch. Engineering and sales are both equally important. And as CEO, even if you have primarily an engineering background, you can not ignore sales. Sales is what is making LinkedIn do well on Wall Street while Facebook is licking it.
Sales does seem to be Mayer's blind spot. Although she has had a great stage appearance since when she was at Google. That is sales.
But product is what has been Yahoo's weakness. And Mayer's focused on product. She will come around to it, I am sure.
