I've recently become a 10k plus user, and I was taking a look at the moderation tools, specifically the deletion votes section. As I was looking at the questions nominated for deletion, it struck me that I don't know what our question deletion policy is.
I gave it a search, but didn't turn anything up, so I thought I'd ask here.
Obviously questions nominated for deletion are closed/on-hold questions, and thus aren't good questions, so my question is which closed questions should be kept around and which should be deleted?
Why the question occurred to me
This question is rightly closed for lack of context, but the answer clearly took time to write, has 5 upvotes (1 silent downvote), and looks to be of value. Is the question worth keeping for its answer? (Similar thoughts on this one).
These questions have two delete votes each, and I realized that since I don't know our deletion policy, I don't know whether to cast a delete vote or not.
