Nerds discussing journalism on HN are obsessed with something called the Gell-Mann Amnesia Effect (it's really the Michael Crichton effect but whatever). It suggests that if you have an area of expertise --- computer science in our case, resurrecting dinosaurs in his --- you can fact-check the news media, and, upon spotting errors pertaining to your expertise, draw conclusions about the quality of the whole publication.
But of course, that's a silly thing to argue. However good journalists might or might not be at reporting on tech startups (and John Carreyrou seems to have done a pretty amazing job with that for WSJ), they're also the ones staffing bureau's overseas, cultivating sources in state and local governments, breaking the Harvey Weinstein story, and reporting on toxic fire retardants in crib mattresses.
