Those of you that have the Google toolbar installed will notice that the
Google parody site has a Page Rank of 4 out of a possible 10.
FOr those of you that don't know, this is a means of Google to rate a site's "importance", and I think the argument (INAL) that by Google assigning some level of "importance" could be taken in some way an endorsement of it's value.
A search for "google" at booble returns no results, however a search for "booble" at google (I'm really glad I'm not trying to speak this...) returns 41,100 results.
