I think it is beyond IE6 now. I am seeing more and more projects that are "okay" with a degraded version of the site on a non-modern browser.
Web developers cringe at shadows, and "non-boxy" effects, because we know the hoops we need to jump through to get there. However, if the project is okay with a "degraded" version of the site, then you can use CSS3 and save time.
I think the mindset of "support" has to change. Sure, have your site work on older browsers, but the good stuff happens when you see it on a modern browser. Users who use shitty browsers, are used to sites looking shitty.
