The problem with Yahoo in my opinion is that is the tail being wagged by the dog (baba), and that Marissa Mayer's hobby is to set cash on fire. Once BABA is separated, and Mayer is 'remixed, a creative CEO may very well be able to turn it around.In my opinion the business is ripe to follow a Berkshire model of using cash flow from the dying business (search engine) to buy a few free cash generating, growing businesses.
