I'm only posting this because I opened the comments and the article in background tabs, read the article, read the comments and refreshed the comments page (my usual workflow on HN) only to see them turned off and the topic marked dead. It's actually my first time witnessing this... And I'm not sure how I feel about it.
That's definitely something I'm interested in doing.
The way I see it is, you'd provide all the actors (people, places, objects), actions, and it would generate a maybe 4 or 5 to get you started by mixing in different styles of headline, from spoiler-style right through to linkbait. You can then carry on, depending on the style of your website.
There's better people than me out there to attempt that kind of stuff, but I'd enjoy taking a stab at it myself.
Yeah, it's in early stages, so I've not gone as far as writing hints/instructions into it to set expectations. It's based on the TodoMVC apps, so you can double-click an existing headline to edit it, but I'm still working out how to best enable that functionality on mobile.
