Yeah i agree that if the question can be in the title it should be imho. It’s nice to see what the post is about in big bold letters up at the top. Obviously some questions will be too long but in any other case I think it makes the most sense.
Agreed. It should be a rule to have the title be a question. I could give or take allowing body content but the question being a title is a must for this kind of community.
Sometimes the question is more complex, and not easily summarized as sentence with a question mark. Or one can have multiple questions on the same subject.
In such cases, imo it makes sense to put something like "regarding the recent XY thing" in the title.
