Because it's as busted as it gets in the CSS game and it causes many people trying to move forward in the web development game a LOT of heartache.
I'm a software developer from way back and when we set the minimum specs for the next version, you either upgrade to be in compliance or you don't.
You think I would write software compatible with Win 95, 98, ME or even XP at this late stage in the game?
Tons of precedence already on the web, if you don't have Flash 9 you can't see Flash 9 files, same with PDF versions, etc.
All I can say it there's no way in hell I'm going to put up with IE 6 until 2014, that's just insanity.
STOP THE INSANITY NOW! BLOCK IE 6! ;)
Fine, if blocking it is arrogant just stop fixing any problems you see with IE 6, refuse to develop for it, and make frustrated people decide on their own to give up that antique pile of bugs.
