Questions tagged [discussion]

This tag is used for questions that ask users to discuss an idea, concept, or problem in an abstract way. A discussion question may not necessarily have a clear-cut right or wrong answer and is often subjective. On Meta, you do not need to use community-wiki mode for subjective topics unless you are asking a "poll" question.
