n3rd [edit] wanted to add I think geeks have lowered their standards. a lot of people are proud to call themselves geeky now, people who know "how to download", use an iPod, cellphones, gadgets, etc. A geek is going to buy an iPod, and nerd is going to hack or build his own. Nerds imo have a deeper appreciation of the technology at work. I've met so called "geeks" who are claim to be "computer experts" yet are still on AOL, blow up their computers, get spyware and viruses, and ask for basic help.
