har, basically every now and then I do go thru and make sure things are validated, however looking at the errors it is generally code that people enter into news stories etc. so not a real problem.
The backbone of the frontpage is valid.
Another problem is adcode and I can't infact modify those without breaking TOS. I believe when I actually added the validation it was cos they were running in iframes but now the code is direct there on the page.
