I’m dropping IE 6 support on my website, using conditional comments asking the users to upgrade, and offer no working features to the IE 6 users, since August 2008.
My other website http://www.macumbaonline.com also shows a nasty warning (it’s a humor website) on IE 6 users, and I didn’t care about the PNG support on websites, since I’m really decided to drop IE 6 for good. If the users want to receive a bad browser experience, with an ugly and greyish website, they can do it, but I got my hands cleans!
Death to IE 6!!
