Seeing political links in color

Andy Baio and Joshua Schachter teamed up to create a totally interesting project for the political season: a way to immediately visualize the links from political blogs on Memeorandum based on how they tend to link -- to more conservative (shown with red tint) or more liberal (shown with blue tint) blogs. They write:

...we used a recommendation algorithm to score every blog on Memeorandum based on their linking activity in the last three months. Then I wrote a Greasemonkey script to pull that information out of Google Spreadsheets, and colorize Memeorandum on-the-fly. Left-leaning blogs are blue and right-leaning blogs are red, with darker colors representing strong biases.

I love the idea of getting a quick, visual indicator of a blogs' social peers (in the link sense). Check it out.
