lol. there are a couple of theories. from what i have read. she did not give much time to google bosses about her departure. sources say that she gave a 23 hour notice. hard to say what is the truth. another theory is that ever since larry page took over the ceo job, mayer was no longer in real control. she became a pr face of the company. and this is the reason why she decided to leave google. considering the deals yahoo has signed up with microsoft (search and ads) and facebook (ads), i do not see yahoo getting close to google in the near future. my first intuition was also that we might see google and yahoo working closely together. but microsoft has literally tied up yahoo as tightly as they have tied up nokia.
Lolz weren't the last 3 ceo's also the last ray of hope for yahoo??? Anyway personally I feel yahoo should have taken the 44 bil MS offered it a few years back... Now I hardly think they will be worth even 10-15 bil
