UPDATE (12/17/2007): My blog has moved. This post is now located at:
http://jason.whitehorn.ws/2006/07/25/How+Good+Is+Your+Browser.aspx
Popuptest.com provides a battery of tests to see how good your browser is. See if your browser has what it takes when put up against these tests.
It think it goes without saying, but...
This site has popups!
Enjoy.
