It's because of this fundamental shift towards user-generated information that people will listen more to other people than to traditional resources.

Search companies, which I won't mention by name, tried to do so many things at the same time, they forgot all about search. They either missed the next revolution of search or they created an opening for a Google to enter.

Technology is always evolving, and companies.. not just search companies.. can't be afraid to take advantage of change.

I use Google+, and I find the quality of the comments are very sophisticated because there is more trust inside of Google+ than there is inside of Twitter and Facebook, for example.

A lot of the Google inventions came from engineers just screwing around with ideas. And then management would see them, and we'd say, 'Boy, that's interesting. Let's add some more engineers.'

If you have a child, you'll notice they have two states: asleep or online.

To me, what you want to do is find a way to let this play out between the virtual world and the physical world...Ultimately, I think society will get there. It will be messy, but we'll get there.
