Top-20 Placement in Google Search Results

On November 6^th, 2010, my Brain Workshop page titled "Tickling the Brain, or Cramping It" had achieved top-10 placement in Google search results for the search string "brain workshop IQ". Click the image below to see a larger view. When I checked today, I noticed that it had slipped to position 11 from 7. On closer examination, I discovered that by entering the search string "brain workshop IQ" with the uppercase IQ yields top-10 placement while "brain workshop iq" yields top-20.

I had never realized that Google search strings are case sensitive. It can be seen from the search results that higher ranking pages with lowercase iq are included hence pushing my page further down.
