This question I tagged as aishes-chayil
because, although the questioner didn't know the tag when they asked, it seemed germain to the topic of the question and all related questions would be of relevance to this one.
Another user disagreed.
My subconscious motivation is well described here:
... tagging is not meant to tell you what the question is about, but to make it more easily findable to someone looking for questions about that topic ...
So which is the appropriate tagging policy, one that would have included the tag on this case or that would exclude it?
