For obvious reasons, we here at Geekanerd are always looking for good ways to explain the difference between a geek and a nerd. In a recent Wired interview, Patton Oswalt (described in the article as "a lightsaber-toting Lenny Bruce") explained his take on it:"A lot of nerds aren't aware they're nerds. A geek has thrown his hands up to the universe and gone, 'I speak Klingon — who am I fooling? You win! I'm just gonna openly like what I like.' Geeks tend to be a little happier with themselves."
Wikipedia defines the two terms thusly:
Geek: "An individual who is fascinated by knowledge and imagination, usually electronic or virtual in nature."
Nerd: "Refers to somebody who passionately pursues intellectual or esoteric knowledge or pastimes rather than engaging in social life"
Anyone else care to chime in with their own personal distinctions?
