The Google Web search is not the only Google search. In performing a Google test, consider searching groups (USENET newsgroups). This is a significantly different sample and represents, for the most part, conversations in English conducted by people who are not deliberately trying to sell products or reach a mass audience. Other things being equal, a "groups" search will typically return very roughly 1/5 as many hits as a "Web" search. Because group and Web searches have very different "systemic biases," hit numbers are not comparable.
