I think that people in the phase between being someone's kid and being someone's parent have always been uniquely narcissistic, but that social media and Twitter and LiveJournal make it really easy to navel-gaze in a way that you've never been able to before. People taking pictures of what they eat and showing them on their Facebook. People assume that people have a level of interest in what they're doing that's maybe far greater than it is, although there is an audience for all that stuff.
