.. how about people just clap, cheer and stamp their feet.. it costs nothing.
Seemingly this season, more-so than previous seasons, no one can be bothered (We all know why.. but many people are not even firing up when we do something good!).
I guess it gives kids who can't clap loudly a way to make some noise.. but IMO its not kids that are the problem. It's the hundreds of adults who sit on their hands and never say boo through the entire game that give me the irrits.
Besides, I am keen to avoid the snotty turd that sits behind me smacking a clapper right behing my ears all through the game ;-) (as has been the case previously). people tend to hold clappers away from their body and near the back of people heads as apposed to hand-clapping.
