Couldn't agree more. It's the sheer vanity of it - endless pouty selfless everywhere.
And it's not just teens doing it, grown women too. Oh look at the subtle lighting in this hazy photo which makes me look 33 instead of 36 - must post on FB for everyone (who knows exactly what I really look like) to see.
The recording and sharing of every moment, mundane or otherwise - why???!!!
And yes, the bullying it lays them open too. And the filth they see online and share. I dread getting to the internet stage with mine.
Re the girl in Ireland, my niggle is this: she is giving out blow-jobs and letting guys grope her in full public view in broad daylight. She knows there is an audience. These kids know and expect there to be camera phones everywhere, they live through them. Did she really think nobody had seen/would see? 
It is of course wrong for it to have been photographed and distributed. And yes it took two and he is a seedy fucker for allowing it.
But, but, what on earth possessed her?
