I don't have the ability to check this off hand, but I will make the assumption that if I try to run this website in Firefox 3.4, or one of the first versions of Chrome, I will get more display and compatibility problems than IE9 and IE10 get on that website.

The circular reasoning of web services saying "We still support IE6 because companies use it" and companies saying "We won't update IE6 to higher because web services still support it" is really starting to get old. Chrome and Firefox now update automatically, and people rarely come out to say "I have Firefox 2, why won't you support my old browser?", so why should we extend the same courtesy to IE6?
