We should all be concerned about the privacy of our data but I don't think most will. I expect that most people in forums like Hive, already understand the concepts. However, when I speak to other people at work, in my social circle or in my family, they don't see the problems. They will say things like, "I have nothing to hide."
We probably need to have a couple of scenarios to explain to people as arguments to help them understand. I have not read about the changes enough to have any though. Any thoughts on the best argument for someone new to the concepts?
