Don't Use an Unpersuasive Font

Don't miss this amazing pair of articles in the New York Times by Errol Morris--the filmmaker who gave us The Thin Blue Line, The Fog of War and Gates of Heaven--arguing that some fonts are more persuasive than others--Georgia more than most, and Baskerville most of all. I'm going to change my fonts as a result of this article, but need to decide how to do so most cost-effectively.
Thanks to Luke Gilman for bringing this to my attention.
