The first NIN concert I went to, I only had to steer clear of certain mosh-pits. The last one I had to put up with a sea of "brighter than the stage" phones upheld to block my view. I don't particularly care if everyone knows I was there, and I can watch incredible videos from home while drinking Rhinegeist.
I do think Kid Rock's approach to sales (tickets and beer) is awesome, and I grew to respect him for thinking outside the box. It's just a shame that I'm not a fan by any means.
