I think that it is done to get the band attention PERIOD .... then with this said it can be silly or very smart ....the banners to say to the guy : I love you or Jon you have a great package or I wanna Bounce on you () are annoying (and I am always the lucky one to have one banner person in front of me )... the song request works very often ....Tayla and Laura in Oostend got their I'd Die For You and our dutch friends got their I Believe and the girl next to me got her Fever at the Kiel show too

I am not anti banner but I kinda think it's boring and annoying when it's UP during the whole show
