A nice joke from Pingdom, "Due to the tremendous interest it has received we have decided to keep this site up and running.".

Look at the quotes on the homepage to :-).

On the other hand, there are plenty of serious sites trying to hasten the demise of IE6:

IE Death March

Free the web – boycott IE6

End6

At Quezi, several of our WordPress plugins don't support IE6 anymore, so we've dropped it. At Uclue we still support it (because Uclue has such a basic design that it's not so painful to make it work for IE6).
