We keep track of traffic to every page of our site through Google Analytics.  The service offers a bunch of really neat tools, including a map that illustrates traffic from different parts of the world.  The map below shows those countries that are home to people who have visited our site since we first officially launched back on June 26th, 2008.  The darker green the shading, the more visitors—so, naturally, the US is darkest.  We've had 21 visits from India, 19 from Canada, and 16 from Australia.  The US has seen 137,220 unique visitors since we launched.  In all we've seen 137,437 visitors from 49 countries.

Can you identify the 49 countries shaded in green?
