Although Hitler and the rest of the Nazis were incredibly horrible men they did come up with some good quotes,
“How fortunate for leaders that men do not think.”
Yet other non-evil people also come up with good quotes. Who can forget Steve Jobs quote when he was ousted from Apple,
"If I were running Apple, I would milk the Macintosh for all it's worth -- and get busy on the next great thing. The PC wars are over. Done. Microsoft won a long time ago."
There was a Steve Jobs one I always liked, something about putting dents in universes but I can't find it now! bah. but another one of his I liked was "Apple's market share is bigger than BMW's or Mercedes's or Porsche's in the automotive market. What's wrong with being BMW or Mercedes?".
My lecturer once referred to a quote "Geniuses of the future will be able to learn, unlearn and relearn", think it was about rapid shifting of pretty much everything in the digital world. or something.
There was a quote from another forum which was on the console war:
Person X - "I don't see why people like the XBOX so much I mean PS2 has outsold it"
Person Y - "More people have AIDS than Herpes. It doesn't mean that AIDS is better than Herpes"
