On RandsInRepose, the description of N.A.D.D.
Here's a tip: If the building you are currently in is burning to the ground, go find the person with NADD on your floor. Not only will they know where the fire escape is, they'll probably have some helpful tips about how to avoid smoke inhalation as well likely probabilities regarding the likelihood you'll survive. How is it this Jr. Software Engineer knows all this? Who knows, maybe he read it on a weblog two years ago. Perhaps a close virtual friend of his in New York is a fire fighter. Does it matter? He may save your life or, better yet, keep you well informed with useless facts before you are burnt to a crisp.
