> I've wondered sometimes whether we're headed towards a post-privacy world, and what it'll look like -- not just one in which there is little privacy, but one in which privacy is not something that most people think about or value.

I think we already live in that reality. The media really honed in on the sharing of your friends list in the case of CA but if you think about it, there are plenty of services where that is public by default (like Twitter). I don't think most people consider that to be sensitive information.
