To be honest. I really don't see the problem.
I like all this stuff. The clappers work. When I had a season ticket. I felt more draw to clap that, than I would to just clap for no reason! Also, The inflatable Canaries. Great. I love those last games of the season when we were already promoted or safe and all the beach balls were out and stuff. Makes it a party atmosphere. I think it will all help. People who don't clap or stand or do anything, are more likely to get involved if they have something in their hands to shake, clap, wave, stand up with. Anything to help the Jarrold and N&P get involved in a vital game.
If it's a gimmick, then I approve to be honest.
