Our blog welcomes all estonians

So I am looking at our site meter stats (it's a pretty cool tool at the bottom of the page). Here is a breakdown of the countries for people who have visited the site:

United States - 92% Here is where I am shocked because I thought it would be 100%
Sweden - 1%
Norway - 1% I am seeing a trend here. We are popular in Scandinavia!
Cambodia - 1% I didn't even know they had internet. I associate their country with brutal dictators.
Spain - 1%
Estonia - 1% I wouldn't be able to find this country on a globe.
Argentina - 1%
Unknown - 2%

How are they finding us?
