What about repetitive tweets? I stopped following so many publications because they would post an article link, then repeatedly change the title or the catch and post the same link. Very frustrating.
The Economist, for one, has a "The Economist, Once" account that only tweets articles once, when they are published!
And yet I rarely ever see anything on my timeline from the 'Once' account, but plenty from the regular account, and not too many repeats. It seems the new curated timeline really hurts the post-once approach.
