Another good review of the Colbert Report. This one from the New York Times.
The article mentions the hilarious "Truthiness" Word of the Day skit, and says, "On his regular feature "The Word," Mr. Colbert routinely mocks the kind of anti-intellectual populism perfected by Fox News. "Trustiness" was his word of the day, he told viewers with a poker face, sneering at the "wordanistas over at Webster's" who might refute its existence. "I don't trust books," he explained. "They're all fact and no heart."
