I agree with that. Sitting in the South Stand it's actually difficult to join in with Greasy Chip Butty when hardly anyone else seems to and the bloke next door is talking at me. It's easier to join in with a few chants at away games when you're surrounded by people who are making some noise - until the game has become a lost cause that is. Gary Sinclair's pre-match volume could do to be turned down a notch or two as well.
When we had the defiant 'Sheffield United' chant towards the end of the Arsenal game I was hoping it might spread round the ground but not surprisingly it didn't. Even when we're winning there's not much vocal support except from the kop and occasionally from the Westfield Corner. Mobile phones, being seated and general disillusionment with the way the club is run must all be factors in the atmosphere
