Last year during the fall holiday season our site received 19.6% of our visits from IE6 or lower. This year IE6 and lower accounted for just 12.2% of visits. IE6 isn't gone but it's pretty close and by next year I expect it to be less than 3 percent of visitors. Internet Explorer 6 behaves so poorly with some CSS scenarios that every designer I know would like to stop supporting it completely. In fact, I've already started to see sites dropping official support for it. Encourage your customers, clients and users to upgrade to IE7 ASAP.
