Toward the top of the FAQ on every Stack Exchange site it has this rule prominently highlighted
You should only ask practical, answerable questions based on actual problems that you face.
I was wondering if this is actually enforced, or if it even should be enforced. I have asked many questions out of curiousity, or sometimes just pure rep-whoring, that have been accepted by the community.
Are these actually a bad genre of questions that should be closed or even deleted? Is the "actual problems that you face" clause merely just a guideline that can occasionally be broken?
You should only ask practical, answerable questions based on actual problems that you [or someone else could reasonably] face.
