I now follow journalists that I've vetted and trust to some extent, and heavily use sites like this to help filter the nonsense. I'll skim BBC and Al Jezeria English, but even them, I withhold opinion until I can get a sense of accuracy and corroboration.
I feel Apple may have the best approach. Comment on nothing, release press releases, and only conduct interviews with vetted reporters.
