This is not something I want to do, at least not right now, but if I were to do it, I wouldn't be sure how to.
This mostly applies to "soft-questions" or question that are more opinions than definitive answers, however I could see this being applied to a regular question.
Say I have a question, which is an exact or close duplicate of another one. I will take for sake of example this question. Now say I've read all or most answers, but I still want some more opinions.
This question is not the oldest, dated april $7$, but still since this date, there have been new users who might not had the chance to see this question pass, and could have a valuable answer/opinion on the matter.
For regular question, maybe the answers posted do not satisfy me entirely or I would like a specific method of solving.
What would be the way of giving like to the question again? I don't think editing the question saying "Edit Hi I would like new answers to this question" is appropriate (This would feel like hijacking the OP), nor posting it again since it is duplicate.
The only thing I thought about was bounty but new answers are most likely to get burrowed under the most upvoted ones.
