We don't have a traditional strategy process, planning process like you'd find in traditional technical companies. It allows Google to innovate very, very quickly, which I think is a real strength of the company.

One of the unintended negative consequences of online advertising has been the loss of value in traditional classifieds. It's simply quicker, simply easier for an end user who's online, on a broadband connection, to look things up and to figure out what they want to buy.

Even though Google may do very well, there will always be an alternative to what Google is doing, and people will always have the free choice... because there's no way for us to prevent them from exercising that choice. That is one of the key aspects of why the Internet has been so successful. No technologies can dominate.

It looks like the thing that separates out the capable students from the really successful ones is not so much their knowledge...but their persistence at something.

I actually think most people don't want Google to answer their questions. They want Google to tell them what they should be doing next.

I think of Google as a set of overlapping things. It's a consumer platform, consumer phenomenon of which search is its fundamental activity, but there are many other things you can do than search... I think of Google as an advertising company who services the broader advertising industry in the ways that you know.

I believe that this notion of self-publishing, which is what Blogger and blogging are really about, is the next big wave of human communication. The last big wave was Web activity. Before that one it was e-mail. Instant messaging was an extension of e-mail, real-time e-mail.
