If I remember it right, I heard something last week about a new directive in EU. All public sector sites should be WCAG 2.0 AA validated. I can actually see why this might be a good thing. One will consider making a building accessible for the physical disable, but when it comes to websites most common argument is "not part of budget"! If you want to make sure a broader audience you must at least try to have a WCAG 2.0 AA site.
Lately I have been reading/hearing a lot about accessibility. And on some level I do agree with some, a new site toady should at least have WCAG 2.0 AA validation. But in today's world, the design wins over needs of the minority!
