NMap.org created an infographic that shows the 300,000 most popular websites in the world, represented by their icons, in relative size to each other:
The area of each icon is proportional to the sum of the reach of all sites using that icon. When both a bare domain name and its "www." counterpart used the same icon, only one of them was counted. The smallest icons--those corresponding to sites with approximately 0.0001% reach--are scaled to 16x16 pixels. The largest icon (Google) is 11,936 x 11,936 pixels, and the whole diagram is 37,440 x 37,440. Since your web browser would choke on that, we have created the interactive viewer below (click and drag to pan, double-click to zoom, or type in a site name to go right to it).
It has a search function, and Neatorama's big N icon is in there.
