If evidence apart from Katie Couric's Pulitzer were needed that the prize has acquired MOL the meaning of a Grammy Award (the judges like you!), perhaps this award to PolitiFact cements the case. Right now it's a bit hard to tell, because it isn't clear what content the awarding jury used as its criteria for judgment. I have located abundant examples of shockingly poor journalism from PolitiFact, but that is not to say that a good number of its entries were not good examples of journalism.
The link provided at Pulitzer.org back to the Times' Web site does not appear to have any specifically indentified "Prizewinning stories."
I look forward to seeing the winning stories posted at Pulitzer.org.
Oct 14, 2009: Lo and behold, the prize-winning stories are now identified!
