Internet Explorer 6.
Released in the fall of 2001 ( that’s nearly 8 years ago now! ) it is woefully out of date in terms in CSS and Web standards compliance, especially in comparision to “modern” browsers such as Mozilla Firefox, Apple’s Safari, and it’s successor Internet Explorer 7. The blogosphere has been aflutter with the news of dropping IE6 after Microsoft’s announcement of the automatic updates to IE8. We are considering removing IE6 support as well, since doing so will allow us to simplify our testing/support matrix, and remove lots of IE 6 customizations from our code.
We are looking for feedback from the community on the impact of this potential change. Please leave any thoughts you have about this ( good or bad ) in the comments below or in the forum.
