Geek, Nerd, etc.

Since it popped up in a discussion recently, I'd like to point out my personal view on the Geek vs. Nerd topic:

A Geek is a person who is fascinated by technical stuff - computers, mathematics, physics, chemistry, electronics, you-name-it. Still, a Geek is able to participate in hour-long conversations (even with the other sex) without including any of these favourite topics. You may want to see thinkgeek.com to get an impression.

A Nerd on the other hand is inept of any kind of social life, conversation, or contact with members of the other sex. While still maintaining the interest in above-mentioned topics, s/he often does not excel at them either. A collection of Nerd thoughts can be found at bash.org - you have been warned.
