#1- It's the economy stupid.
#2- Even for guys that have remained unaffected by the downturn, game day costs are ridiculous, my house is paid for and I can only swing 2 games a year.
#3- As far as those apps go, I am all for it when there is no play on the field. There is nothing worse than being outside in the cold watching a game while the play stops for a tv time out.
#4- The emphasis on decorum in the stadium is such that for a lot of loud young fans the game experience is affected. These are the guys/Girls that buy the last 3000 seats to the game.
The announcer yelling FFFFFFFFFirst Doooooown is enough input from their end.
