Cynthia Says™ is a web content accessibility validation solution, it is designed to identify errors in design related to Section 508 standards and the WCAG guidelines. The main purpose of this portal is to educate web site developers in the development Web Based content that is accessible to all. Cynthia runs more tests than Bobby and is free. I think the site itself fails the accessiblity test, 'cause it doesn't have "WCAG" in an <abbr> tag, nonetheless it's a good tool. [via zeldman].
State of Validation 2003. Off the 430 W3C members, only 28 (6.5%) have sites that validate with the W3C validator as either HTML or XHTML! This represents an increase in standards compliance of 75.7% from the year ago tests. [via the big orange Z]
