The "Ask a Question" page in meta.stackoverflow.com has this block of text to the right of the question:
How to Ask
Is your question about the Stack Overflow engine or websites?
We prefer questions that can be answered, not just discussed.
However, MSO is specifically meant to be a discussion area. A place where SO and its sister sites can be discussed without fear of being closed or downvoted as being subjective, belonging on UV or belonging in the SOFAQ.
The text of the "How To Ask" block should reflect that.
