I like it. With Google becoming a standard research tool, you might as well learn how to do it right. I was in a teaching credential program last year, and we had a tech class that devoted one day to using the advanced search feature of Google, and trimming url's etc. It was a lot of fun. BTW, in referencing the article, we semi-serious number theorists know that the number one with 100 zeroes after it is spelled googol. It used to be if you entered www.googol.com, you were redirected to www.google.com.
