Um… I’ve worked for a rather gigantic mining company where I learned a lot… toooo much 🙁
I learned, for example, that the follow is policy-defined and not inherent, meaning that the data must be strictly protected, and not only obfuscated:
Since targeted ads are so much more effective than nontargeted ones, websites can charge much more for them. This is why — compared with the old banners and pop-ups — online ads have become smaller and less invasive, and why websites have been able to provide better content and still be free. Besides, the fact that I’m going to Houston is bundled with the information that 999 other people are Houston-bound and is auctioned by a computer; no actual person looks at my name or my Houston-boundness. Advertisers are interested only in tiny chunks of information about my behavior, not my whole profile, which is one of the reasons M. Ryan Calo, a Stanford Law School professor who is director of the school’s Consumer Privacy Project, argues that data mining does no actual damage.
