We are focused on features, not products. We eliminated future products that would have made the complexity problem worse. We don't want to have 20 different products that work in 20 different ways. I was getting lost at our site keeping track of everything. I would rather have a smaller set of products that have a shared set of features.

In the future, search engines should be as useful as HAL in the movie 2001: A Space Odyssey-but hopefully they won't kill people.

As we go forward, I hope we're going to continue to use technology to make really big differences in how people live and work.

We've seen a massive attack on the freedom of the web. Governments are realizing the power of this medium to organize people and they are trying to clamp down across the world, not just in places like China and North Korea; we're seeing bills in the United States, in Italy, all across the world.

People try new things all the time. By now, the people who succeed have to be very sophisticated.

Solving big problems is easier than solving little problems.
