On Stack Exchange, I've pretty much only ever used Stack Overflow, and one thing they push (fairly) strongly is that questions should have specific answers. Make yes or no questions, or questions on syntax or the usage of functions, or whatever.
The point is that your question should create answers, not discussion.
My question is - what if you actually need a small discussion? For example, if you want people's opinions on options for some kind of syntax or usability of your program - a "How should I..." as opposed to a "How do I...".
Is there a subset of Stack Exchange (or of Stack Overflow) for those kinds of questions?
