Leave it to WSG to assume that Facebook.com is just another website. Log into Facebook and profile your session with Firebug or a similar Javascript tool. What you will soon find is that Facebook is one of the most complex web applications out there today. It has a huge number of AJAX & animation events throughout the many sections, as well as a live chat feature similar to the one in Gmail. Just to give you an example, Facebook has a continuously running "presence" monitor that sends information via AJAX to the backend even as the logged-in user is idle, to track and identify how users interact with the site. One of the uses for this is to tell other users, with certainty, if you are currently online. Facebook has had a warning message on their homepage for a long time; I remember seeing it at the beginning of this year. It's a way of letting users know that some features of the site are bound to be hindered because IE 6 is so outdated. I think this message went up around the time that Facebook chat was released (April 2008), this is why: http://www.theangryhedgehog.com/2008/04/facebook-chat-and-ie-6.html Currently, Facebook has a redesign of their site which is opt-in until the testing period is over, which does not work with IE 6. It is well understood that the new version features a lot more Javascript & AJAX than the current design, and therefore, will take a while to make compatible with IE 6, if at all. Facebook has not finished the opt-in, testing period for their new design, so it is not correct to say that they are downgrading support for IE 6. We can only say that if those users are still blocked when the new design is actually released to all users (which is scheduled to happen soon). We might not agree with the way Facebook sniffs the user's browser, but the point I am trying to make is that Facebook is far more a web app than many people on this list may have ever known, and it certainly does have different requirements than our blogs and public-facing brochure sites. Also, since Facebook hasn't actually finished their latest redesign, there is still a chance that they will support IE 6 in the end; but I doubt it.
