Accessibility expert Joe Clark in a new article on ALA, "To Hell with WCAG 2" says:
WCAG 2 is not too broken to fix, but we have no reason to think the WCAG Working Group will actually fix it. The Working Group is too compromised by corporate interests, too wedded to the conclusions we see in the current “draft,” too broken in general. What you see in WCAG 2 now is pretty much what you’re gonna get—permanently.
As such, WCAG 2 will be unusable by real-world developers, especially standards-compliant developers. It is too vague and counterfactual to be a reliable basis for government regulation. It leaves too many loopholes for developers on the hunt for them. WCAG 2 is a failure, and not even a noble one at that.
The (Possibly) Good News:
Joe + friends are going renegade:
Maybe all we really need to do is to fix the errata in WCAG 1... I can announce that such errata really are going to be published, and my friends and I are going to do the publishing. After the manner of Zeldman’s CSS Samurai posse, which put CSS layouts on the map for browser makers and developers, the WCAG Samurai [wcagsamurai.org] will publish errata for, and extensions to, existing accessibility specifications.
