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:
which, funny enough, in it's original form was:
As per the label part I will quote Neil deGrasse Tyson. I think what he said applies everywhere:
So since computers are becoming an everyday part of our lives, people should be more educated, more computer literate and privacy is very important!
Mass privacy is difficult to achieve; hopefully we will, and honestly apps like Girls Around Me are scary enough to start showing people what the hell is up. Hell, I'm uncomfortable with ever sharing my exact location with people I don't know; as a rule of thumb, I probably don't like the person, so why invite them near me?
But yes, a campaign for education about facebook privacy, along with movements to start promoting it, would be very, very useful. And, if I'm honest, I actually don't mind the whole "personal advertising" efforts. I don't think I've as of yet bought anything online that I saw through advertisements. I might have clicked a link once in 2003. That was it.
