Rant
Yes, I do, because I use IE6 (edit: I use it in lieu of other IE's, I browse exclusively with firefox and opera, but sometimes I need IE). I'm a bit tired of people complaining about it; I mean welcome to the world of development.
And to be perfectly honest, a lot of people blame their own incompetency at developing in CSS and JavaScript, and lack of research into what they are seeing, and so on on IE, when they are at fault, for not following proper development processes.
There are some general bugs that need to be worked around, but in general the so-called 'problem' is very over-blown.
Simple Answer
Yes I do support it, and I find it pretty easy, using frameworks to help me (jQuery, reset css, etc, simple downgrading of functionality).
