This question already has an answer here:
Is there a way to display unanswered questions ordered by post date (newest unanswered first)?
Browsing unanswered question using the 'no answers' tab (based on vote count) does not make sense for less common tags, as it's hard to find questions that can be answered or are worth answering. There are also hundreds of up-voted:
- questions with answer in comments
- questions with right answers but not accepted by the questioner
- questions waiting for the questioner to clarify
- outdated questions
On the other hand 'newest' contains answered and accepted questions, which i don't want to either answer or see.
