Visitors from around the world.

I'm intrigued by the Site Meter "world map," which shows where in the world my last 100 or 500 visitors came from. You see the dots all over the map, and you can click on them. If you do, you can see the "referring URL." Often, I'm touched. At first. Someone in Egypt is reading me. Why did they come here? I've been hanging out on Site Meter long enough to understand those visitors from around the world.
