Bill - after muddling through the first parts of the patent it sounds very much like a system I think they have been using for a long time - it basically takes the average growth of a site and looks at how fast a newly found domain grows, how often the pages really change, how often womeone searching for that specific info chooses an old doc versus a new one, etc etc.

Basically I think they are just writing up some of the averaging factors they have buit in to the algo over the last few years based on their link tracking theyve been doing and bringing in some of the preventative measures theyve added to control script generated sites - but I sure dont see anything that would lead me to a sandbox let alone a playground like some of these people have in their minds
