The site I'm in charge of (a small local radio station, about as far from the early-adopter crowd as you can get) now only has 19% of its visitors from IE6, with 53% using IE7. (For completeness, Fx has 20%.) For the next iteration of the site, I've made the decision to end IE6 support.

We're a tiny organisation with very limited resources (the web team consists of two people and we write and edit the content as well as taking care of the design and development, plus other jobs in the station) and we can't justify spending insubordinate amounts of time supporting this ancient browser with an ever-declining share of our visitors. We'll make sure it isn't completely broken in the blasted thing, but users of that obsolete version will just have to live with design glitches.
