Much of the huge drop in crime rates in the 90's can be traced to Roe v. Wade. Steven Levitt just rocketed to the top of my reading list.
TradeSports has betting on current events, like whether WMDs will be found in Iraq by Sept. 30. The historical data on pricing is awesome; even better is the free marketing they got via the botched DARPA project, so now their markets should be more liquid.
Last night, I put up a list of New College blogs. Piqued with "where are they now" curiosity, I ambled through NewCollege.org and saw that Joy Kanwar was working at Skadden (which is the 100+ hours/workweek madhouse of a securities law firm where Jason worked). I wonder how much variance there is in post-NC life, probably not as much as we'd like to think. ;)
