Information Architects have just released the 2008 version of their ‘map’ of the Web that looks and reads like a subway map. You can either take a look at the clickable online version or the downloadable PDF one. It may be useful to compare it to the 2007 version to see how their opinions of whether sites are moving ‘up’ or ‘down’ have changed or to see what new sites are on there and which ones dropped off.
