Last year Joe Clark published the now infamous article "To hell with WCAG 2.0" on A List Apart.
If you didn't get a change to catch it first time around the article criticises the then newly released WCAG (Web Content Accessibility Guidelines) 2.0:
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.
In the article Joe Clark also announced the formation of the "WCAG Samurai", an invitation only group tasked with publishing errata for, and extensions to, the existing Web Content Accessibility Guidelines 1.0.
The WCAG Samurai have recently released a draft version of their accessibility guidelines which makes for a much easier read than the vague and often non-commital language we're used to from the W3C. I for one welcome these guidelines as even though having another set of guidelines does muddy the water a little I'm sure they will come in useful to web designers and developers alike who are finding the Web Content Accessibility Guidelines 2.0 difficult to understand and implement in their day-to-day work.
