Where people find the time...

I came across this via reddit.com. It's Clay Shirky talking about where people find the time to create entire encyclopedias on the Internet just for fun. He talks about how media consumption is shifting towards a participation-consumption, and the fact that doing SOMETHING (e.g., playing World of Warcraft) is better than doing NOTHING (watching another episode of Gilligan's Island). I think it's 15 minutes or so, but an interesting talk.
