The reference tag has no description yet. Is it intended to be used for a question that asks for a reference where one might learn more about a certain topic, or document one's intuitive understanding about a topic?
For comparison, Academia has a tag called "reference-request," and that's how I see it used there. The official description says:
Questions requesting an answer supported by reliable evidence and including citations to said evidence. This is in contrast to questions requesting answers based mainly on personal experience.
