What's the Motivation?
A few years ago, I was intrigued by the introduction of A9.com, a search engine hosted by Amazon, that promised to save a history of anyone's searches. My initial thought was that such information might be useful in an archeological sense, allowing future generations to see what held our interest at a given time. Dose of Reality: A9 search data was collated with each user's Amazon account.

In Whose Best Interest?
It's now been confirmed by SearchEngineLand, that Google has been personalizing search results for me, based on my past searches and click-throughs, but my search engine of choice actually knows much more about me than that. Consider the data that Google has collected through your use of Google Apps by visiting your personal Google Dashboard.
Although the potential for archived search histories was known to me, it was a bit of an awakening today, to come across my personal Google Web History. If you have a Google account, you've been presented with Terms of Service, and have granted permission for Google to use what you submit, post or display (11.1). If you're concerned about the security of this data, the Google Privacy Centre might allay your fears.
What does the Future Hold?
Whether or not Amazon and Google follow parallel or intersecting paths, these two giants play key roles in Epic 2015 an visionary piece (now almost 5 years old) that extrapolates current trends.
Google and Amazon each offer some terrific 'Free' tools, but maybe it's high time we consder the price we're really paying?
