William Gibson, a while back, talked at some length about what he called "mediated personalities" that covers much the same territory.
The whole thing is pretty much what has convinced me that I Don't Get Fandom, and why I avoid trying to meet famous people for the sake of meeting famous people. I don't want the chocolate of a real person in the peanut butter of my auctorial construct. If I hang out with a famous person, I have to temporarily forget that they are famous, or I get all weirded out.
I have a personal relationship with the auctorial construct of my favourite authors; we spend so much time together! In my head! But the real person, I don't know at all.
