> I agree with you in principle, but in practice you'd need to exclude all the major outlets. That's a pretty big hole in media coverage.
WSJ is (as far as I know) the only major one that doesn't meet the "easy to circumvent" rule. And the "major outlets" predominantly post general news, which is less relevant to HN.
In either case, flagging the post with a reason would be an educational benefit to the poster and the readers.
