I have added a cool free real-time statistics widget from whos.amung.us in the menu-bar on all my pages, including this one:
If you click on this widget (here or in the menu bar), you will see how many people are currently browsing this site, in what part of the world they are located, and what photos they are looking at (in real time!).
For the most interesting display, click this widget, then click on the "Recent" on the "readers" page to see the countries of the visitors and the page they are looking at (and you can check out those pages!).
