Information Architects Japan have produced a lovely and witty map of the most popular websites on the Net at the present time. Unlike a lot of other similar projects they have used the Tokyo JR network map as a visualisation method meaning that if you know the JR lines you can make further inferences about the ‘stations’ . . . If you have been to Tokyo you will know which are the ‘cool’ parts of town, and which appeal to different demographics.
The interactive HTML version is particularly useful, and they have included a whole slew of sites that are usually missing from other ‘maps’.
