All good points. Where do you stand, on an ethical basis, with how far is too far for any entity to knowingly take this kind of info and manipulate your life for your (and their) 'benefit'. I like Google, but when you mention 'textual fingerprinting' it's already the case that Google does some of this when you search, and for use in Adsense, right? Maybe not reading your texts/posts yet but Google has 100's of millions of people's search and browsing fingerprints, whether they know it or not...
