People that think anything that they post on the Internet is private, including Facebook, are completely naive.
I think almost everyone understands this, at least on a fundamental level, but people who are not as immersed in computers/internet/websites are (generally speaking) simply not as aware of the full implications. The reality now is the ability to deep mine databases and actually make sense of it all. Only the biggest companies can currently do that (read: Google et al), and as I said in my posting above, new technology will make that analysis even faster and more accurate.
So the problem is that we've reached a point where data from many thousands of varying sources can be read, analyzed, and accumulated into specific individual profiles. Those profiles will be updated in virtually real time. Google will have much of this information and will be a broker to sell it to others who are willing to pay. Some here don't care, and that's fine until it's used against you ~ once that happens, the stain is in place and no amount of rubbing will take it away.
