This is why I put the "problem" in quotes - I'm not sure if it can be called a problem. If we believe in people's freedom to choose what they want to read, then it isn't.

When people talk about bringing back the good old days of journalism, they dream of the time when cigarettes were unfiltered and you could make a living researching a single story for three months. Or this Request for Startups talks about making mass media write stories that are good for the society (as opposed to people's immediate reading preferences).

I don't see any good technical solutions for achieving these goals, because these goals require changing people's preferences, and require funding that goes against people's preferences.
