Alright, thanks for pointing to them.

- This guideline feels a wee bit sad, because editorializing can be valuable (a title might be crystal clear in context but nonsensical once pulled out of it).

- But I understand how we generally don't want it as it might lead to linkbaiting and misrepresenting the original title.

Also, didn't they change some titels to less click-baity titles in the past?

Still happens, I saw it happen the day before yesterday. I kind of like the fact that the title on HN is specific and to the point.
