FYI this data is collected by Google Search History You need to login to your google account while searching for your searches to be logged to their servers. Google people are getting too deep into analytics of late, last year they acquired a major analytics company, Urchin, Now this should redirect to the Google analytics page. Interested thing is Google is ready to give the power of analytics to the entire world free, which used to cost $299, when it was Urchin.
So much of Data Center power is giving Google to analyse and organise world information, this is really awesome information for the world to see. But is the information in good hands, will it continue remaining in good hands, how much is this kind of statistics going to make the world better, will it change our online behaviour, how are the intelligence agencies, say CIA connected to Google. If we have so much of statistics to see, how much of statistics is available internal to Google.
So many Qs ... my fav quote again ... Time will answer.
