Have you ever had your vacation ruined because the font on a sign was poorly chosen? Or upset by a movie because the font (on a pressure gage, no less) was anachronistic? If you are, then you are likely a font nerd! Font nerds are obsessive about…well, fonts. If you are one or you know one (and I know several), then you will know exactly what I am talking about. If you don’t, read this, Design – Mistakes in Typography Grate the Purists – NYTimes.com, and be glad you wouldn’t be able to identify Helvetica if someone put a gun to your head.
