Atmosphere is fostered by the concentration of those inclined to sing in a compact area.
The predominance of STHs means that the current seating arrangement is relatively fixed, so that the fans themselves are limited in their ability to organise this kind of set-up.
Therefore, to see the kind of boost in atmosphere that we want, the club must be prepared to reorganise the stadium with the above objective in mind. This will mean upsetting some STHs in the short term - perhaps compensating them with a reduced ST price for one season might alleviate this to some extent.
I haven't said anything especially new here - a lot of us understand our fanbase and the situation on matchdays well enough - it's just disappointing that the club are uninterested in taking meaningful action on such an important issue.
