Another stack exchange site could be dedicated to this type of questions, let's call it InfiniteLoop. Moderator would move questions from others sites there instead of closing it, and no answer could be accepted. It may be enough to both maintain SO quality/focus and please those who like open ended questions ?

By the way, I happen to like these open ended questions because they complete dispassionate theory by being opiniated. Maybe it just me, but I think both are needed for a broad understanding of any subject.
