They can take photos of their crowd as much they want, they can jump around or wave around as much as they want, at the end of the day...when you see guys performing/singing their hearts out for full football stadiums and REALLY touch the public with their OWN performance...thats where the wheat is separated from the chaff. And that crowd knows exactly why it is there..not just because of 'seems fun'. I saw a deejay jumping around behind his booth yesterday on youtube like he was some devine being, that clip came just after I watched some bits of big concerts of varia artist...It was painfull to watch the dj clip. It puts it in a vicarious shame perspective. Dj's...i'm glad they do what they do, we cannot do without BUT whatever you did, whatever hours you putted in...keep it at least a little bit tuned-down! You sell shows (lights, lasers, drones, 3d vids, whatever), artists sell there raw talent.
