SOTU, So True

Here's a great resource for history buffs and data wonks: the text of every State of the Union address is now archived on the Web. And not only that, the Webmasters have counted the length in words of each SOTU and--dig this--the approximate grade level of the text (funny how it's been declining over the course of the 20th/21st centuries). It also maps key words used throughout the texts and their relative importance. Hours of fun to be had here.
