This reminds me of One of my favorite moments in the past couple of years is when I went to see Joanna Newsom in concert. Just before she sat down to perform, the host for the theatre said "now, I want you all to put your cameras down and your cell phones. Really enjoy the music. You can tell everyone how it was after the show. Seriously, this a real experience and you don't want to miss it taking pictures."

Everyone in the audience put away their phones/cameras almost immediately. The result? You could actually see people enjoying the music; not just bragging about being there.
