As far as people writing decent headlines, not many stand out.
I discovered Ellie Guzman recently, because Jon Westenberg tweeted about her in the same tweet that he mentioned me.
Andrei Draganescu has some good headlines.
Ben Noble has good stuff overall, and most of his titles are provocative, but don’t wander into that hyperbolic and sensationalized zone. SF Ali is also great, but you’ve probably had all your stuff recommended by him.
Josh Spilker has some good titles and work to go with it.
Anna Now writes good stuff in the realm of poetry and elegant prose.
I can’t think of any more at the moment, but I know that there’s more in the folks I follow. I try not to follow people who I don’t think write stuff worth reading, but not all of them post frequently enough to pop up in my mind.
