Google Poorly Developed Homepage

Quite an amuzing story has been circulating about the number of html errors returned on the google.com homepage.

In a WebmasterWorld thread that the Google home page, does not validate fully.  I ran a quick check at the very useful W3C validation and returned 66 errors, including a No DOCTYPE found.  Should this matter? who knows, its just quite amuzing that the kingz of the web have html validation errors.
