I was at a prospect last Wednesday and we were going through some examples of sites and why they rank well in search engines. So I had the prospect take the seat and asked him to perform a search on a keyword phrase. The page currently up was Google but the prospect typed "google.com" into the Google query field.
He Googled Google. :)
It seems like many people type in google.com into a search engine based on Wordtracker, but I wonder how many people actually Google Google.
