Major cultural shifts are always interesting to me. Whether one agrees with the behavior of the NSA or not, the fact is they did it, continue to do it, and probably never will stop, as you noted. At the same time though, people are
willingly putting most of the same information on the internet anyway, perhaps because they don't realize the implications or perhaps because they have thought it through and they really don't care.
We are in a weird transition time where people haven't figured out their new boundaries, where teachers get fired for the
mildest of vacation photos with their fiance', where teens don't yet understand that those party photos are going to truly haunt them when they start their job search.
Or maybe they won't--there will come a point where either everyone stops putting their personal life online,
or we acknowledge as a society that everyone does that, that everyone has embarrassing moments, and stop using it against one another. I'm suspecting the latter, myself.
