I guess this could be looked at as a veiled feature request: make the results of the Unanswered search more obviously 'unanswered,' or 'not answered well.'
One possible way to do this would be to change the way that the style of the answer count indicator box is modified. It is pretty obvious to users that when a new question is submitted, the answer count is 0. This is obvious because the UI shows a box which says
0 answers. Also, the style of the box carries this meaning (on SO, the background of the box is maroon). When the first answer arrives, the text of the answer count changes and so does the style of the box.
It would be helpful (in the unanswered tab as well in other list views) to know that there are no upvotes on answers. This could be accomplished by keeping the style of the box as is until there is an upvote. The view would show the answer count but you would be provided with subtle feedback that there still is a need for strong answers.
