This tweet response is even dumber when you read what it is responding to.
Why yes the presence of a devastating parody account of your predictably hack headlines means you probably should put more thought into them.
The "industry" Maggie Haberman is complaining about is the readership and quite often fellow journalists. Haberman put access to Trump above everything else. We don't need a Trump whisperer, who half the time is just laundering text messages from Trump as journalism.
The headline point is also not trivial. Joe Kahn in his own admission acknowledged that today much of the Times' audience consumes only the headline. So it isn't like they aren't aware that the headline is so crucial. They are completely aware.
And we know most of the answers to these questions. Because Joe Kahn himself explicitly said he was overcorrecting from the previous Times leadership during the BLM protests. He also explicitly said they weren't necessarily going to cover the newsworthy stories, but the popular issues. So Maggie probably can't answer these honestly.
