Do you have a hierarchy of geeks in your head?

I was introduced to this concept recently while browsing the internet, that people rank nerds into different levels of social failure based on their various interests.

Do you find yourself perceiving nerds this way? In your worldview, is a Doctor Who nerd more or less socially awkward than a Star Trek nerd? Are they both above or below a Star Wars nerd?

Where does coin collecting and taxidermy fit into your scale of awkwardness?
