Today as I was going through my feeds I came across this great web tool called Internet Map and thought it might interest you as well. Internet Map, as its name suggests, is a Google Map of the 350.000 largest websites in the world.
Websites are included in circles in the map. The size and visibility of each circle corresponds with the popularity of the website it contains . For instance, the biggest circle that is clearly visible in the interface of the map is of Facebook, the surrounding ones have Tumblr, Yahoo, Google, etc. One of the coolest things about Internet Map is that it lets users easily use the search functionality to look for and find the most popular websites in individual countries.
