Depressing Validation Results

On a whim, I decided to attempt validating every website I mentioned
yesterday.  Overall, XHTML won out the results.  But they are depressing none the less.

The
Results are bad enough as they are for the XHTML websites, but not a single HTML website validates, not even
the WHATWG.  Irony much?
