This fun, long-time-to-load map called Presidential Watch '08 plots out political blogs across the Internet after lumping them into specified categories and measuring their influence, all based on some algorithm we won't pretend to understand.

Blogger Ethan Zuckerman explains: "The graphs are influence graphs, showing who links to one another within “like-minded” communities. The idea here is to look at linking between political blogs in only a political context, discarding other links that are outside of context. The result is a tight, pretty map that shows a decided red/blue (conservative/liberal) split in the US political blogosphere, plus a small set of common sources used by both sides. The graph is remarkably easy to explore, allowing users to mouse over it and see the media sources referenced."
