I'm relatively new to this SE but questions like [this one][1] would probably be closed on most of the others I'm more familar with. However, it's highly upvoted and many people have contributed answers or comments so I assume I've probably just misunderstood the local SE policy. Could someone point me at some clarification of how the opinion-based flag should be used on Academia.SE?
