Should "Does everything have to be a question?" be added to the FAQ?
Even though the button to start a new thread says "Ask Question" and the FAQ says "What kind of questions can I ask here?", not everything on meta is a question. For example, feature requests are often posted however is most natural, which may or may not be in question-form. See, e.g., this thread: Do feature requests have to be formulated as questions?
There are also poor-quality posts flagged on Stack Overflow because they're not real questions.
I suggest that it would be helpful to point out in the FAQ:
- That almost everything posted on Stack Overflow and meta should state a clear question, but
- There are exceptions where it is acceptable to post non-questions, such as feature requests on meta.
