Database Nation...

Interesting article in The Guardian on Monday about the databases of information held on us:
"Amazon is hoping to patent ways of interrogating a database that would record not just what its 59 million customers have bought - which it already knows - or what they would like to buy (which, with their wish lists, they tell the world) but their income, sexual orientation, religion and ethnicity. The company, of course, already knows who we are and where we live."
