That depends. Certain people (speaking in general) need to be challenged before they will take any action. They think that as long as the boards are quiet, they don’t have to worry – or worry more if the issue becomes public.
Should there be any animosity? No. Is it required? No, with some exceptions.
This board serves a useful purpose in allowing people to interact with each other – but there will always be some disagreements, and often challenges simply because of human nature.
Me, I like to tweak people… but only when they have it coming to them, if it serves no purpose I certainly won’t waste time saying anything.
