Congrats to Infovis who are helping people visualize the blogosphere, and especially for being so integral to the non-virtual realities of these big cities. Example: the blog maps of New York City, and Washinton DC work perfectly fine, but the map of London does not come when you want it to - just like the buses and trains do not come when they are supposed to - part of the charm of living in London. Maybe the link will work tomorrow?
