> One of her flaws at Google is that she was too tough with her colleagues in the early years, and these people have memories like elephants.

Maybe she's grown, but maybe the culture itself has grown too. How many women were in tech positions and 1999- and how many of them were senior executives? That toughness may have been a requirement for her to get where she did at Google, and if it's true that she was able to adapt yet again to a changed culture where that wasn't needed then I expect her to do damn well at Yahoo.
