Let me add a couple more prospects I think would be strong candidates:
Michael Wolf , ex MTV president. Wolf is smart, nice, focused and well connected. A New Yorker with Valley ties, he'd bring good operating skills and a breath of fresh air.
Hilary Schneider, Yahoo EVP. Hilary might be stretched to lead such a big business, but she has an ability to make decisions the other big Ys lack. As a former publishing person in a software world, she has a rounded point of view, and she's ambitious, therefore p
resumably willing to stretch.
Jim Bankoff, former AOL guy. Jim's been out of AOL for 2-3 years, and while he is young, he's a good businessman, and a focused negotiator. He's done the big company thing, but gets technology development. And he works hard.
