The Wired story (http://wired.com/news/culture/0,1284,62537,00.html) about the HP paper, which is a less-math/more-why-we-care read than the original paper, and Stephen VanDyke's How News Travels On The Internet (http://stephenvandyke.com/2004/03/08/how-news-travels-on-the-internet/), inspired by the above.
