That one is excellent! Being a fellow geek, I am going to have to start using PICNIC more often. "Oh, that is a PICNIC. What you need to do is..."
Also, "known error" is so very true. I really hate when one of the lusers sends an email saying "why did this not work? I have never seen this before!" and I know that (1) others have found it, (2) an email went out to all of the affected users explaining the problem, and (3) he has specifically reported it before and received an individual response.
Lastly, I have a couple of my own definitions that fit in with this:
Geek: Someone who was born interested in technology and picks up on it naturally.
Nerd: Someone who has an interest in technology and studies extensively to learn about it.
Dweeb: Someone who thinks they are in the same class as a Geek or Nerd, but does not have the technological aptitude and/or intelligence.
