The meaning of life, I learned last week, is either gene replication, 25 years or less in jail before parole or the name of a Monty Python film. Or maybe it's simply to do God's will, as a 15-year-old girl wrote in response to the question I posted on Expertcentral.com. Along with Abuzz.com, Askanexpert.com, Knowpost.com and Xpertsite. com, Expertcentral is a kind of collective brain made up of thousands of self-appointed experts who will answer virtually any question, no matter how mundane or inane, for free. Other websites, such as Keen.com and Exp.com, do the same thing for a price.
