geeks, nerds, and dorks

Friday night I was playing Taboo with David and Kristin, and the word "geek" came up. I said it was something bad to be, and David disagreed with me. He said it was bad to be a dork. (David also works for microsoft, and he is obviously a computer geek.) Then we discussed the difference between nerds and geeks. So being the complete nerd that I am, I looked up the definitions of geek, nerd, and dork, and here it is.
--------------------------------------------------------------------------------------------------------
Nerd:

First used in Dr. Seuss's book If I Ran the Zoo, 1950 as the name of an imaginary animal.
Possibly from Mortimer Snerd, the name of Edgar Bergen's ventriloquist dummy.
Possibly from the acronym N.E.R.D. on the pocket protectors of employees of the company Northern Electric Research and Developments; it should be noted, however, that speculative etymologies based on acronyms are almost always false (such as "port out, starboard home" for "posh" and "to insure promptness" for "tip").
Possibly a pronunciation of the word "drunk" spelled in reverse ("knurd"), used to mean a person who does not drink at parties - this seems somewhat contrived.
