Many IT professionals and IT companies have been trying to get "Internet Explorer 6" outta market. Many sites came to make people aware that IE6 is dead. But still IE 6 is being used. Some use it outta ignorance, while some use it cause they are forced to use.
I myself hate IE6 cause of it inability to render most of the cool things that other browsers do easily. However i was recently forced to use IE6, mainly cause my bank didnt support any other browser. I had faced similar kind off situation earlier with our college website which would render ok only on IE6.
The worse part is that even sites of big education bodies such as mumbai university have sites that only runs on IE6.. (now they have updated it to run on any version of IE but still only on IE).
I pray that the day soon comes that developers and designers start making site compatible with all browsers. Atleast completely functional on all browsers.
