Wow. I was just checking out my personalized home and I saw this:

and

Holy cow, if that is true, that's huge!

Hmm. I only get "Results 1 – 10 of about 11,190,000,000 for * *. (0.07 seconds)"....

That was from Google's main page – from personalized I get the same as you mentioned. I wonder...

Thats a hell of a lot of pages, but you sort of have to take into concideration that websites have more than one page :)
