Contagious media

"Blogdex is a research project of the MIT Media Laboratory tracking the diffusion of information through the weblog community. Ideas can have very similar properties to a disease, spreading through the population like wildfire. The goal of Blogdex is to explore what it is about information, people, and their relationships that allows for this contagious media."
