Journalists are addicted to attribution. Before Twitter, they had to call people for quotes verifying or denying something. The tradition was 2 sources to verify. There was even a time that anonymous sources were frowned on. If they couldn't get them on the phone, they had to track them down and ask in person. That's why there are multiple scenes in "All the President's Men" where the reporters are knocking on doors at people's houses at night.
All that is old school now and replaced by the quick drug-like hit of posting "so-and-so tweeted". It's enough to write about a post of some kind and not actually get comments or context from anybody else, because there always posts for "opponents say" or "advocates say".
I was a web developer for a newspaper and knew they were doomed when they started writing articles about their own comments section.
Implication and notoriety rule the day.
