In To Hell with WCAG2 Joe Clark, provides a detailed, fierce, and apparently well-based critique of the nearly finalised version 2 of the World Wide Web Consortium's Web Content Accessibility Guidelines. Here is the introductory paragraph.
The Web Content Accessibility Guidelines 1.0 were published in 1999 and quickly grew out of date. The proposed new WCAG 2.0 is the result of five long years’ work by a Web Accessibility Initiative (WAI) committee that never quite got its act together. In an effort to be all things to all web content, the fundamentals of WCAG 2 are nearly impossible for a working standards-compliant developer to understand. WCAG 2 backtracks on basics of responsible web development that are well accepted by standardistas. WCAG 2 is not enough of an improvement and was not worth the wait.
Some readers of Fortnightly Mailing are accessibility practitioners, and "plain English" comments on whether or not WCAG2 is a step forward will be welcome.
Thanks to Joe Clark for sending me a comment linking to the above definition of "standardista".
