It seems Google has a new little features, "Notes", I've just spotted this little trinket for the first time a minute ago. If do a search, at every link, next to cached (etc.,), there is "Note This"... If you click on it, it saves the page for you...
I posted a thread about this and attached a screen shot: http://forums.digitalpoint.com/showthread.php?t=291057
theres a chance google may use the data to give certain pages higher ranking. pros to this theory: 1) humans are choosing what content they prefer (related to a search, also) 2) this is, ultimately, what makes a good search engine cons: 1) it can be 'spammed', ie. webmasters "mass-noting" ... contrary to the negative side of this, unless somebody creates a mass amount of google accounts, would it be worth the effort?
