At his point we have 20 questions tagged lesson-ideas. 4 have accepted answers, and only 2 are on the unanswered tab.
We also have 17 questions tagged curriculum-design. 3 of which have accepted answers, and only 1 is on the unanswered tab.
In both cases some of the questions have needed some back-and-forth in the comments to refine the question, and others have been understood, and answered, rapidly. In a limited number of the questions the chat facilities have been employed to either address the question itself, or to find an answer when the question didn't seem to fit well into the Q&A format of StackExchange.
These types of questions are important to the users of the site, now and in the future. Not all, however, are a good fit for the StackExchange Q&A model. Some are too localized, or too broad, and are likely to be closed, in time. The need, however, will exist for our users in either case.
I propose that we have a chat room for the site, other than the main chat room, to which we can point users when they ask a question that is unclear, too broad, or too localized for the site, yet may be salvaged after extensive discussion. The comments to a question will often result in an automatic invitation to a chat room when they grow long. Doing so, however, is only visible to the users active in the comment thread, or who later happen to visit the question later. A dedicated chat room could be "watched" by active users, and when someone posts there we can join the conversation without having to find the question and follow the link in the comments section.
In response the most recent use of chat for this, I created a room and gave it a topic and name such that it could be used for future questions as well. If the community decides this is a good idea, the room can be kept open, and once we have mods appointed they can take ownership of it. If the community decides against this idea, the room can be allowed to die on its own time.
