Here is a collection of various quotes found in the sigs of people posting on Slashdot over the years. I had noticed and retained many of the quotes, but recently someone posted this tasty collection, so I figured I'd put it up here for posterity. Some are quotes from well known personalities, some are originals, some are old, many are certainly misattributed. Most are geeky in their humor.
One of my favorites: "Why does everyone always overgeneralize?"
