37Signals will begin phasing out support for IE 6 today as it happens (http://37signals.blogs.com/products/2008/07/basecamp-phasin.html http://37signals.blogs.com/products/2008/07/basecamp-phasin....). I note that even they had originally planned to phase out support for IE 6 in August this year, but extended the deadline. I think this is a decision that you really need to make after analysing your particular market. If you have a lot of government/corporate clients who may be slow to move to new technology, then possibly the extra effort to get things sorted for IE 6 may be worth it. But if like 37Signals, your market is more made up of small/medium business and tech savvy users who move relatively quickly to new technology, then possibly the time to say goodbye to IE 6 is now. Only you know for sure.
