My favorite Wikipedia entries. Typical for an INTP, I will read just about anything, including the label on a ketchup bottle as long as it doesn't require interaction with a live human being. The Internet is perfect for us nerds.
As for nerd category, place me in the Science Nerd, Techie Nerd, Military History Nerd and All Others Nerd categories.
