I look after an Australian e-commerce site. About 6.5% of our users are on IE6 (I assume they're mainly office-workers on shitty, out-dated PCs).

That is way too big a chunk of revenue to ignore in the name of ideals or standards or what-have-you.

But please, feel free to redirect any IE6 visitors to your blog to whatever the latest "IE6 is shit and you're an idiot" single serving site of the moment is.

I agree that IE6 is a turd, but have never found making my designs work in IE6 too much of a hassle. There has always been a positive ROI beyond just pleasing the spec-writers.

I think a lot of developers write overly complex, fragile mark-up with lots of nested floats and the like. Keep it simple and you'll realise IE6 support is generally just a few tweaks or at worst a conditional or two.
