I think the twenty-first-century modality is exhibitionism. Exhibitionism is our contemporary strategy for maintaining our boundaries, which is to be boundary-less - to put everything out there before somebody comes and violates or penetrates something that we're keeping sacred.

Every time you enter a space, you are on public display. Nothing is private.

I have to admit to you, I am the person who's done probably the least analysis on the selfie, because it's a bit like pornography for me. It's this masturbatory, repetitive act that I'd rather wasn't part of my routine.

More platform-sensitive generations will make distinctions between online and in-person intimacy, whereas fourteen-year-olds have very nuanced online selves and might embody their virtual identity in the physical, analogue version of themselves. They have a much more pluralistic understanding of the self.
