I think that's still true, it's just that the internet + social media let a lot of people become publishers at once, and we haven't yet decided to whom we should listen.

There are a lot of mistakes being made for which consequences have not yet occurred. Journalists of previous generations on whom we could rely had built up lifetimes-worth of reputation. On whom can you rely today? It's an open problem which I think is solvable in spite of today's difficulties.
