I agree the petition is useless and will if sent to Editors will go straight to recycling. However, I do think there is a real issue with all our news providers focusing more and more on "soft" news and gossip. Reporting the mishaps of celebs is so much cheaper than real investigative journalism. Bid media companies are currently cutting their budgets as more and more news outlets mean more and more competition.
IMO there are various routes that campaigns should follow to protect high quality news: Encourage the Government to give the Press Complaints Commission real teeth. Expand its role so that there is an overarching body to monitor the training of journalists and encourage best practice; Get media literacy made part of the National Curriculum. Children need to be taught to be discerning in the media they consume; Encourage the BBC to review its plans to trim news budgets. It is the one organisation that does not have to play in the market, and cater to the lowest common denominator; Encourage Ofcom, the broadcast regulator, to adandon its plan to loosen the requirements for Channels 3,4 and 5 to provide high quality, prime time, local and national news.
