Blogdex is a research project from the MIT Media Laboratory that traces the diffusion of content, represented in the form of hypertext links, over time, through blogs.
“Programs such as Blogdex offer a window into the networking structure of the blogging community, an opportunity to systematically analyze large textual datasets, and a way to think about meaning in the online environment.” (From Katrina Kimport’s research report.)
