I thought this was pretty cool: Via TechCrunch comes the above subway-styled map of Internet trends. It was developed by a company/group/whatever called Information Architects Japan, and they have several sizes of the image available here. Suitable for a desktop background, IA suggests.
What I think is potentially interesting about this page is that it represents a bunch of sites I know nothing about, so it’ll give me some ideas of stuff to check out sooner than later.
