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.

For many people, Google is the most important tool on the Web.

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

If you can find something that you're really passionate about, whether you're a man or a woman comes a lot less into play. Passion is a gender-neutralizing force.

Multinational companies have spent tens of millions of dollars building their Web sites and related e-business infrastructure and marketing to create brand recognition and loyalty. Unless these companies understand what drives customers to their Web sites and what keeps them there, there is no assurance that these efforts are being directed where they will have the most impact.

Really in technology, it's about the people, getting the best people, retaining them, nurturing a creative environment and helping to find a way to innovate.
