We are excited to make an investment in AOL's future. It gives us more opportunities with more advertisers, and more kinds of advertising programs.

Q4 is behind us, and what the Boston Scientific investment thesis is now is the future, and particularly the future with Guidant. I expect, if they allow us, that's going to be the focus of the conference call.

Management is defense. You basically say, 'This is the direction; this is where we're heading,' and then it's my job to get everything else out of the way. All the other things that can become a distraction keep us from executing well. Get those out of the way, because the team ultimately needs to run in that direction and execute well.

We can't afford not to make this investment.

Before Google, I spent the summer building a program that would look at what websites you would go to and what websites other people would go to - and built a collaborative filtering program that helped you find related sites to look at.

I think Google should be like a Swiss Army knife: clean, simple, the tool you want to take everywhere.
