As recently as the '70s, people were forced to see information that they didn't agree with in newspapers and the like. Now there is so much information you really can build your own walled garden that just has the stuff that reinforces your view. I think it applies to all of us. People are really going into these separate camps, and that's the big social challenge in this age of too much information. How do we crack that and create a common dialogue?

I think the most important thing that a company can do, not just in the customer space but the employee space, is to be completely open and completely honest. Don't pretend that you're doing something that you can not do. There's an old saying in Silicon Valley, "It's not a bug. It's a feature."

I think companies over the last 10 years have done a very bad job of explaining to their employees what the intrinsic risks are. All I know is, if you wait until you let the employee go to deal with the issue of how do you communicate to the employee about being let go, it's too late to do anything.

Sometimes I think we're on this world for three reasons: to be useful, to tell each other stories and to collect stuff. It's the only explanation for eBay. We love to collect stuff, and at least if we're collecting stuff in cyberspace we're not deforesting the Sierra Nevada.

Responding to climate change will become the obsession of the next decade in much the same way terrorism was this decade's obsession.

Every new thing upsets people. We all know someone that has a teenage kid who sits in the room and the television is on, their iPod is on, they have the computer on and at least three other electronic devices going while they're doing their homework. It drives the dad nuts, but he can't complain because the kid's a 4.1 (GPA) student.

More information and more communications foster world peace and understanding. But connecting extremist nut cases together on the Web - whatever flavor extremism they are - is a really bad thing. More information may not be a good thing, either.
