Images like that concert photo really are unnerving. Instead of actually just having fun, people have become more concerned with letting everyone know how much "fun" they're having. It's so strange to me. "See how cool I am? Aren't I special?!?!"
And cynical? I don't think so and I'll explain why.
It goes way beyond events like this concert. It's the notion of publishing every aspect of your life just so others will notice it.
I once saw on facebook where a girl had posted an image of her family all huddled together, grievously hugging: "Just found out that my grandma has cancer." Who decides that's the time to step back and snap a photo for social media? And why, to get "likes"? Maybe add a filter somewhere in between.
My brother saw the same thing as that concert image, but at a funeral.
It's ALL to get noticement and it weirds me out.
It's evident that some people express little interest in the music being played, but rather enjoy taking selfies with the artists in the background.
I really dislike this cynical attitude, it almosts sounds like 'these people aren't enjoying the concert properly the way I would, becuase they're taking photographs, therefore they must be there solely to take those photographs, and therefore they are inferior to me.'
Just as many people find it more enjoyable to play with their phone instead of paying attention to their local environment, there are people who find it more enjoyable to broadcast "Look at me, I was here", rather than participate locally (many often do both, but there's a noticeable amount of folks who don't participate and only document, be it photographers, or selfie obsessives). Taggers share the same mentality. Also concerts and events in my city are often free, so it attracts a more casual audience who's bored enough to have left their house and yet not invested enough in the event to be engaged or participating.
Wasn't that always an important part of many teenager's lives? I don't think the underlying behaviour changed, just the way it's expressed. Instead of telling everyone how great the concert was (regardless of the actual experience) they can instantly upload a cool picture to instagram.
.. not really dancing for the music or the moment, but playing to the camera feed and taking selfies with the artist in the background.
