Recently, I mentioned to Abbas that a topology of the blogosphere would be useful. I had in mind a visual representation that would show the traffic between blogs. This kind of visualization would, for example, help us to see whether and to what extent the blogosphere is segmented according to like-mindedness. I haven’t found one which has that information, but I have come across some other representations of the blogosphere.
My favorite: “a map of the city that shows where the bloggers are, organized by subway stop. Find out who’s blogging in your neighborhood!” A similar site, the location of bloggers in DC, can be found here. The one here shows bloggers in the UK.
I personally like this one, “3D Artists Around the World. . . a geo-coded database of 3D artists, dynamically displayed on world map. Individual points are overlaid on the map every few seconds. Mouse over a point to obtain the artist’s name and location. Click on the point to visit their site.”
A brief article in e-zine InfoVis.net about visualization of the blogosphere has more links.
