CNN weighs in on this vitally important question. Personally, I feel much the same way as Futurama co-creator, David X. Cohen:
"To me, nerd is a compliment and geek is an insult," said Cohen. "I feel like with 'nerd culture,' [it sounds like] the nerds have triumphed. 'Geek' has a negative connotation. I'd rather be called a nerd. I love being called a nerd."
I don't view the term "geek" as an insult, but do I feel the subculture that embraces Star Trek, World of Warcraft and Dungeons & Dragons is nerd culture. Geeks are merely dilletantes who obsess over some aspect of that culture, but don't live it every day.
I am Nerd!
