You are right. It is very tricky to determine which sources are credible. The National Enquirer broke the John Edwards love child story, despite not being a credible source. And on the other hand we see credible news sources distort the truth to fit the narrative every day. However, the first stage is create systems that let us add news events and reporting in an objective form in which it can be assessed (we have done this already), and then to work on systems that allow us to assess their validity (work in progress). I think something like stack exchange can work, and it will be interesting to experiment to see what works.
