Opera also ran the pages indexed by MAMA through the W3C’s validation tools to see how many conform with standards. The results show that only 4.13 percent are valid. A more startling conclusion that Opera derived from its MAMA data is that only 50 percent of sites that display a badge touting validation are actually valid. This could indicate that many sites which are initially designed with valid HTML later cease to be valid as changes are made and new content is added.

And I’ll just add in here that http://barbariangroup.com does pass validation. What is interesting is that our blog page fails validation due to embed code that we grab from other sites to embed content in blog posts, which totally reflects the findings of that study. Too bad because I know Kenji
