Just saw this comic linked to on digg (so it might go down), thought it was very relvant.
P.s. please look at my quadrant machine topic: http://www.overunity.com/index.php/topic,3375.0.html (http://www.overunity.com/index.php/topic,3375.0.html) It is a very simple idea compared to most of the stuff on here - please give me some input if you can.
