It would be cool if Q&A site, would allow to directly show all dev responses (many game forums have things like developer tracker, that show posts from developers).
we could use something like this here. It would included answers as well as comments. It probably make easier to check if question has been already answered. Specially in department for more abstract questions (like X,Y,z is not working this way), or for feature requests.
Extended by tag. for example only developer responses to question with certain tags.
