My Homepage is about 4 months older than IE6, though I manage it for “just” 2.5 years now. We are nor style freaks, we don’t need any animated fluffy-colourful flashskin, but IE6 ain’t even supporting the basic webdesign features which showed up during the last 4 years. We decided not to support IE6. Saves ourselfs a lot of time and a lot of stress as well. IE7 isn’t perfect but waaaaaaay better and out for 3 years now. Use it, dammit!
