The original question was "why does nobody care?", the OP then asked why the plight of your club isn't getting media attention.
A major reason why nobody is paying attention is because rightly or wrongly, nobody is doing anything to get attention. A question that will always follow a remarkable protest (however unclear the message, or how poorly conceived) is "Why are they protesting?".
The "Cockney Mafia" banners, the mock funeral, the march, the walk out, the PardewOut.com website all got attention from local or national press.
West Ham's pitch invasion, Charlton's various protests, Blackpool's, they all got national media attention too. Which is what the OP was calling for, wasn't it?
If you want to know how national media attention would benefit your club, that's a different question. One my replies are, as yet, not intended to answer.
