I recently saw this test on someone's blog, and I HAD to know how nerdy I was. The person who had it on their blog scored a 93... and he works at MS (nerd kingdom). So, I figured I'd probably get in the high 80s.
One of the questions is: "What are you doing on a friday night?" and I answered: "Out with friends". Which is true (or wednesday, or thursday, or saturday night too). So, I don't know how I could decrease my nerd quotient.
The sad thing... I was answering some of the questions 'moderatly'.. trying not to expose my full nerdness.
