I found very nice link. There is a short description: 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
So that means: If icon of any website has 16x16 pixels it means that not many people visit it . You can type here most of sites which you know. Our clanpage has there icon 416x416 pixels.
