I love going to gigs, but.. I prefer to remember my experience of what happened, which is not something that can be caught on camera.
(note 1; I know I'm not the target audience for any social network)
(note 2; I really dislike the fact that the audiences to gigs are just filled with people holding up their mobile. Instead of trying to get a pic to put on FB, why don't you try enjoy actually being there?!)
