There is also an excellent analysis of Facebook by Marc Andreesen (remember? the guy who did Mosaic and Netscape). In a nutshell: the carefully designed instant awareness of your friends of the application you just started using, makes them use it too. That cascades onto their friends, and so on. The result: your servers get blown apart in very short time. You might be famous, but flat out beaten by traffic."
