Does it really need to be said?
http://awkwardthingsisaytogirls.com/2007/02/why-geeks-make-good-lovers/ I particularly like this excerpt:
Geeks have excellent finger dexterity. Geeks roll dice. Geeks play video games. Geeks flip pages in books. Geeks type a lot, and use characters like ~ and ^ and | that no one else has any use for. Geeks use calculators in postfix notation. As a result, a geek knows how to use his or her fingers to greatest possible effect. Whether you have a button that needs pushing or a joystick that needs joy, a geek is the person for the job.
