This document is a rare change of seeing the Google Algo written in black and white. I spent a bit of time going through the Google Patent Document and came up with a much shorter version that should lend itself to easier analysis. The simplified version is at: http://www.best-web-directories.com/google-patent-application.htm Please let me know if I missed anything important. In case you missed it, the original document is at http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PG01&s1=20050071741&OS=20050071741&RS=20050071741
