Hmm, your document is not valid. But darnit, I aint going to tell you why <g>

So I've been playing around trying to shift from table based to CSS finally
and I've just about got there.
 
Except it doesn't validate.
 
Now I can accept I haven't quite got there yet, but normally I get a listed
of where I have fudged up.
 
Not this time.
 
http://validator.w3.org/check?uri=http://idunno.org/new.html
 
fails, but doesn't tell me why. So is my XHTML so bad the validator barfs
completly?
