The pace at eBay was frantic and urgent. We knew that if we didn't move fast, somebody would come into the market and quash us. Participant doesn't make a lot of sense from a financial investment perspective, so it's unlikely that other people will be approaching the business in the same way. So you see less urgency; you see a thoroughness and willingness to spend extra time to get things right. Which I think is really important.

My views tend to be centrist. I'm not a big fan of George W., but my politics tend to be more Republican than not.

Participant (Productions) is the only production company in town that has a double bottom line: social good plus financial returns. It's too early to tell how our returns are going to look - though all signs are promising - but social good is what we're really after.

Not everyone can be Gandhi, but each of us has the power to make sure our own lives count - and it's those millions of lives that will ultimately build a better world.

Philanthropy is all about making a positive difference in the world by devoting your resources and your time to causes you believe in. In my case, I like to support causes where "a lot of good comes from a little bit of good," or, in other words, where the positive social returns vastly exceed the amount of time and money invested.
