But whatever you think of defining oneself through a laundry list of commodities and pop-culture references, Hancock is a lot more accessible than some art-world superstars (or their imposters). Zaha Hadid, for instance, has not accepted my friend request, which I submitted weeks ago. Maybe she would be more receptive if I changed my profile picture? Or maybe it’s because I passed on all that nasty gossip about how she behaved while installing her show at the Guggenheim last year? Well, if you happen to be virtual friends with her, please put in a good word for me.

Yoko Ono also hasn’t allowed me to be her friend, either, but then there seem to be dozens of people claiming to be Yoko — maybe I didn’t approach the right one? Like the rest of these electronic personalities, the many impersonations of Yoko point up the fragility of identity, online or otherwise. Trying to befriend art-world celebrities feels like playing the impossible game of “Who Is the Real Phony?”
