Read Katie Hafner's work (in "Cyberpunk") on what happened with the Morris Worm very carefully, and Paul Graham's involvement with that incident seems a bit more interesting.
"Ha!" I thought. "Why buy the book when I can just cleverly search Google for the right keywords?" But then: http://www.google.com/search?hl=en&suggon=0&client=f... . This is getting to be more of a problem: people pose questions to a bigger audience than they pose answers to, so Google is likely to find the question rather than the answer.
Just think that today, if the same thing had happened and that conversation had occured --- prior to the launch of the worm, that is --- Graham would likely be prosecuted as an accessory.
