As of a week ago, we have a canonical tag. The Q&As in that tag (now two) are intended serve as an instrument for closing as duplicate any questions (usually about basic knowledge) that get asked repeatedly.
It’s a great tool for finding the right question to dupe with, a problem that keeps on happening when dealing with these repetitive questions. We could also use canonical Q&As when there is a bunch of similar questions that are not duplicates of each other but of a hypothetical master question. The canonical Q&A would would then make that question real.
I wonder whether this tag is a good and sufficient way handle this. Are there any better options?
