>Young people grew up with social media and are very savvy about segmenting their public persona from their private one. Young people understand intuitively that asking an edgy question on your public persona is an act of edginess in itself.

While that is true to a certain segment, I'd argue that the young people are actually worse than the older ones. There is a gap of those that experienced the internet before things like facebook/twitter became the face of the web, those i'd argue do fit the mold you're describing, the generation after them however? Their entire lives seem to be on the internet, with no regard for anonymity or oversharing with complete strangers, many dazzled by the idea of getting fame through those interactions and often turning what should be personal relationships with real friends into exclusively virtual interactions, and it compounds when you get older and you're further incentivized to put yourself publicly out there with LinkedIn and such. Of course there is a bit of a hyperbole but the point still stands.
