Right. I found this on Flowtown (posted by Dan Martell) . It is a great overview of the Evolution of the Geek, but wouldn’t you agree that one could add a few more here?

How about Geek Girls (and Girl Geeks), Formula 1 Geeks, MC-Geeks (and all the subcategories like HD-Geek, Ducati-Geek, Triumph-Geek, Moto Guzzi-Geek, Honda-Geek…. ) …

Or Wine-Geeks, and Beer-Geeks (definitely different to Food-Geeks) …

What else would you add?
