Shiny, happy Midwesterners

This site has some really cool maps of personality traits.  I have no idea how well-thought out the measures are, or how they got this kind of data.  But, it's kind of fun to see the patterns.  Nice, agreeable people (i.e. mind-numbingly dull helpful types) all over the middle of the country.  Neurotic, open-minded types (i.e. interesting wack-jobs) on the coasts.
