It's based on Technorati links, so take this with a large grain of salt, but here is Discover Magazine's visual depiction of the blogosphere:
The white spots are "hubs" around which various communities revolve:
- Daily Kos, in the liberal blog area, is the biggest blog in the world, bar none. Note that it's off to one side, which is consistent with the fact that Kossacks read (and link to) Kos pretty exclusively. I imagine the smaller white dot is Duncan.
- BoingBoing at the center of a cloud of gadget/tech blogs.
- Livejournal .
- Michelle Malkin (not instahack?!) and right-wing blogs.
- Porn blogs.
- Sports blogs.
I was suprised that Kos was more popular than gadget blogs. These stats are based on links, so would still think a traffic-based map would show a different result. I was also surprised, as I said, that Reynolds is not the center of the right-wing world, and also surprised how many right-wing blogs there are. Intelligence is a normal distribution?
