I’ve found a number of cool maps online, most come from strangemaps.wordpress.com and I’m looking forward to the completion of LA City Nerd’s Los Angeles Neighborhoods and Communities map.
Something I saw today though is quite possibly the coolest map I’ve ever seen.
Information Architects Japan mapped out the 200 most successful websites on the web right now and orders them by category, proximity, success, popularity and perspective. It’s also really great looking because it’s modeled after the map of the Tokyo subway system. It reminded me a lot of a graphic called “Linkology” that I saw in New York magazine in February ’06 but I like this one much better. See for yourself: the clickable online version is here.

Maybe one day your website will be on that map
