A lot of Google stuff doesn't validate. In fact - check this:  http://validator.w3.org/check?uri=www.google.com&charset=%28detect+automatically%29&doctype=Inline&group=0

Strict w3c compliance just isn't top of their list, and I have to say that I'm with them on that.  There is a lot of reason to do it of course. I am not detracting from that and it is definitely a good thing to aim for. However it isn't always critical and sometimes you need to weigh up the benefits against other gains.

I know that there was a statement/response to this from Google at one point back in history.  I remember that they sited filesize as one example of a benefit that can be gained when you move away from strict compliance.  There are other advantages, but in Google's case I think it is more than it just isn't that important to them. You have to remember that this is the search engine that was originally built by two guys who didn't know HTML :
