Haha you are just trying to get me stirred up aren't you.
No camera nazis, "light" security, and no rules!
If you see any pics or vids of the audience at any show - everyone has their phones out and is taking pics, taking videos, posting updates, and whatnot. I think every artist should welcome that. I mean how much money are they going to lose on a smartphone-quality video?! They aren't going to say "well I saw it on a phone so I don't need to go". They are going to say "That looks soooo fun, I should have been there and will go next time".
I'm one of the most classic rock traditionalist there is but I fully embrace smartphones in concerts and posting to social media. I think both older artists and concertgoers have to accept it at some point. They don't have to love it or participate, but Facebook, Twitter, Instagram, and YouTube are the future and most concertgoers are going to be posting things from the concert to those networks... I think people who have a problem with that are most likely fuddy duddy artists. And I'm an old soul but I still embrace that. I think it's great for exposure and fun to share with friends. I love the artists who encourage it too and have special hashtags for the tour, and not just accept it. I don't see anything wrong with social media. In fact, for an introvert like me - it's my main source of communication - right or wrong. I know real life is important, but it's tough for me.
