Craig Newmark on the Web's Next Big Problem -- Trust

What does Craigslist founder Craig Newmark think is the next big problem the web has to solve? Who to trust online.

To solve it, he believes that what the web needs is a "distributed trust network" that allows us to manage our online relationships and reputations. He talked about "reputation and trust ruling the web, just the way it does in real life," and how he was looking to big players such as Google, Facebook and Amazon as the kinds of entities that would have the scale to handle such a distributed trust or reputation management network. And he said that despite some occasional missteps by both Google and Facebook when it came to privacy (Google Buzz and Facebook Beacon, respectively), he believed that both were acting in good faith and had a policy of "not being evil." Newmark called some form of distributed trust system.
