Visualizing the Blog "Echo Chamber"


Last week we looked at Ben Fry's Atari 2600 Cartridge Source Code project, which used game source code to make attractive, data-rich images. But Mr. Fry has a lot of other interesting projects, including an illustration for a New York Magazine article entitled Linkology that demonstrates how blogs link to each other in a sort of "global popularity poll" (also read: how the image was created).

In Fry's image, he presents blogs in a list from left to right, with the more popular blogs starting to the left (at the far left are Boing Boing, Engadget, and PostSecret). Colored lines connect the blogs when they link to each other, with the color of the line getting brighter as it approaches the source of the article being linked to. Different colored lines denote different topics (technology, politics, etc.). The cumulative effect demonstrates the intensive interlinking of blogs, and shows a cascading effect as content starts at the major blogs and is linked to by smaller blogs down the line.

Is it just me, or is there an echo in here?
