I have to read NYT, WaPo, WSJ, Economist, The Guardian, Breitbart, TimesofIsrael to get full information. NYT does a lot of censoring/under emphasizing of critical information. Of course there is also general reading that is important.
Of course, this number of publications is already a large investment of time so I don't think it's reasonable to expect anyone to do more.
They are also mainstream media. They provide a very narrow set of viewpoints.
One example? No newspaper publish material as significant as wikileaks.
The CIA used to have the Foreign Broadcast Monitoring Service, later the Foreign Broadcast Information Service, now the Open Source Center. During the Cold War, they had people listening to most of the national radio stations of the Communist countries and taking notes. Most of this was utter drivel; Radio Albania was mostly long speeches by their dictator. Sometimes something important would be announced, and it was the CIA's job to notice, so somebody had to listen. Must have been an awful job before it was computerized.
