It is not about beeing harassed because you are not a 6'2", and, meanwhile you do, the others don't know how to handle themselves... I think It's all about the masses being used. It is about the ability to record everything you do and connect it with your persona. If you are not careful online they will know who and what are you talking to/about, what your income is (so they can estimate what your potential ability to buy is) what kind of fashion do you follow the clothes you wear (so they can select what to offer/put in front of your eyes), what do you usually buy, the places you frequent and spend your money to drink to eat... You might remember the buzz created some months ago by the phrase: If you are not paying for it, you're not the customer; you're the product being sold.. which, funny enough, in it's original form was: The member of facebook is not a customer, they are the product. The advertisers are the customers. As per the label part I will quote Neil deGrasse Tyson. I think what he said applies everywhere: Labels are mentally lazy ways by which people assert they know you without knowing you. So since computers are becoming an everyday part of our lives, people should be more educated, more computer literate and privacy is very important!
