I'm talking about very good and old questions (5 years, 80 000 views) with many answers (good and bad ones) but no perfect answer you know.
Ok, nothing special for now.
But... Time goes by and common knowledge + technology increase. We now have the power to answer the question with an optimal answer and provide the community with a cutting edge solution.
The problem is that the question is really crowded with too many answers, too many votes, and a brand new optimal answer will never be considered, completely lost in the crowd.
Is there a way to get a new (high-quality) answer out of the crowd?
p.s. : If there is no way, can we think about how to find a way? Like promote the answer in comments? A special feature? The problem is that this kind of action cannot be objective.
p.p.s. : I can provide you with a case example on Stack Overflow if you want. But it's my answser and then it's not very objective. Let me know.
