The Web is a compelling new medium being put to all kinds of uses, by everyone from banks to Cub Scouts to flying saucer cults. That said, it can also be a powerful folly amplifier.

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?

People were touchingly naive at the dawn of the Internet revolution when they said the Internet will route around censorship the way it routes around damage. With any revolution, the establishment catches up and figures out how to screw it up. The answer is to keep technology advancing fast enough so that those who would try to control it can't. It's up to people to defend what they care about. We shouldn't be complacent that this stuff is going to be a force for good.

As Stewart Brand (co-founder of Emeryville's Global Business Network) likes to say, "Information lasts forever. Digital information lasts forever or for five years, whichever comes first." There are examples everywhere. The tapes from the original Viking landers that went to Mars are at (NASA's) Jet Propulsion Laboratory, but there is no machine that can read the tapes.

This new world of personal media - the Web, the Internet and et cetera - not only delivers the world to your living rooms, but everywhere. And we get to answer back. And we're expected to answer back.

I think it was Samuel Johnson who said, "There are two kinds of information in this world: that what you know and that what you know where to get." The tools help the latter, and that's what keeps us from going nuts. The sense of overload comes from the gap between that sudden jump in volume (of information) and the tools we have to make sense of it.

The arrival of television established a mass-media order that dominated the last 50 years. This is a personal media revolution. The distinction between the old order and the new order is very important. Television delivered the world to our living room. In the old media, all we could do was press our noses against the glass and watch.
