The way i read the original post was generally trying to establish why SIDC has decreased over the years, and .net has flourished. I dont think club history, name, or rivalry comes into that.
Two clubs can easily exist side by side, and have a few laughs along the way. We need to sort our club, and start being more positive instead of moaning because Scott has small-man syndrome, so feels he needs to spend £50k on his ilegal sidelights. (that was humour btw)
