A new Pew study cited in the Times shows that even as old people complain about their kids' oversharing, they're actually the ones who are letting it all hang out. "People ages 18 to 29 were more apt to monitor privacy settings than older adults are, and they more often delete comments or remove their names from photos so they cannot be identified."
There are two possible explanations for this: One, incriminating data is never posted by or about our nation's adult sector; two, adults have no idea what they're doing.
