Certainly, part of the charm of jtv is that he's just a normal guy doing normal things. It's fascinating to see how the simple act of wearing the camera changes his life - people talk to him differently, he gets invited to things, he's suddenly something of a celebrity just because of the presence of the camera.

But imagine that camera on Natalie Portman or Paris Hilton, or someone whose life is already incredibly out of the ordinary - while some of the charm is lost, it certainly would add a lot of intrigue.

There's also a lot of opportunity for using this kind of platform to do loosely narrative driven content: someone wears it for a single date, a job interview, to document a startup, to document making a film, etc.

If she's walking around with a camera on her head like Justin then you won't be seeing much of her boobs unless she has some kind of weird obsession with them. But we can always dream!
