If anything this story (h/t Bruce Schneier) is indicative of very rapidly changing ideas of privacy:

Young couples have long signaled their devotion to each other by various means — the gift of a letterman jacket, or an exchange of class rings or ID bracelets. Best friends share locker combinations.

The digital era has given rise to a more intimate custom. It has become fashionable for young people to express their affection for each other by sharing their passwords to e-mail, Facebook and other accounts. Boyfriends and girlfriends sometimes even create identical passwords, and let each other read their private e-mails and texts.

I think some adults understand this, but not all. Has anyone ever swiped your journal and read it and taken something you wrote completely out of context? Imagine emails and teen boys full of testosterone and aggression? Not a good combination, that. The digital age presents an altogether different set of risks, up to an including emails and photos finding their way on to the internet. Once there they are impossible to delete. Impossible.

It's one thing to share a locker combination, but sharing digital data? While I am really trying hard not to be an old-fogey about this, from my experience with tweens and teenagers: it is impossible to explain to them the risks. And the adults in charge really are falling down on the job.
