Interesting TED Talk on privacy and one which highlighted in my mind an interesting crossover that exists in the Information Security industry.  Information Security professionals are often in an excellent position to breach privacy, and are often called upon to do tasks that do just that (though only in an ethical and responsible manner). On the flip side and possibly as a result of the above, they are often the strongest proponents of improved privacy controls and the most outspoken critics of those that breach them.
