So, despite all of those good works, the stock is going down because its competitors, Google and Facebook, are ahead of Yahoo in trying to cover their flanks against this kind of buying. Google does it in search, while Facebook does it in novel ways to get eyeballs and a plethora of users, including mobile users -- double the number of overall eyeballs that Yahoo has.
