On many SO and SE-specific sites, there are many questions that have been resolved by comments but not an actual "answer". When looking through the "Unanswered questions" filter, this is what the majority of questions are.
Perhaps we could add a new feature where if:
- Question has 5+ comments
- OP has used "Thanks, resolved, worked"
- Question has been inactive for 3 months +
Questions are marked as resolved, to save them from showing up on the feed.
