I was exploring the "Unanswered" tab trying to find an unanswered question I could answer. I think there should be a mechanism to sort out the Questions that shouldn't have answers so they don't appear there. Questions such as FAQ for Stack Exchange sites and Stack Overflow mentioned on NPR's "Wait, Wait... Don't Tell Me" and NY Times are wonderful to have as a reference point - but don't need an answer.
All you need to do is refine your search queries slightly and you'll be able to browse through posts which have no answers at all. For example -
There is also some confusion about the title of that "unanswered" tab. The posts listed there are not necessarily unanswered - but rather do not contain an "accepted answer".
If this type of question were on the main site then I'd be concerned.
However, as it's Meta, these types of question are fine.
The meta sites bend (if not break) the normal rules of Stack Exchange in all sorts of ways - including the type of "question" that is allowed.
You can use Meta for announcements etc.
