Yeah, I've seen this phenomenon....I actually believed that most of the kids (much younger than me) were letting their friends hear the concert, and of course some are taking pix...of each other no less....but I digress. Stereogum's commenters reveal that sometimes the effect is lovely - as in U2's shows when the uberglows of cell phones look like so many stars in the stadium seating. BUT I WOULDN'T KNOW AS I MISSED THIS TOUR. AGAIN.
But again I digress. I was annoyed as fuck by the cell phone calls and picture taking and this old bag would like to see them banned from all shows. Who's with me?
