Typesetting, and then proofreading typeset pages, is a major activity here at deadline times. This had made me a spotter of typos and bad kerning. It’s impossible to read a newspaper or a magazine or walk down the street without spotting glaring errors on a daily basis. So I was glad to read an article in the Chicago Tribune about two men who are traveling around with Sharpies and paint on a crusade to correct typos on signs!
