We should have an explicit feature for recognizing/rewarding/glorifying answers that save peoples' lives.
The OP of this question over at Great Outdoors commented in the accepted answer several years later stating that the advice given in the answer literally saved their life. Aside from feeling that the question and answer are criminally under-voted, I also feel that there should be some kind of extra-special reward for this kind of answer - some kind of "Medal of Honor" or other commendation bestowed only for these kind of stories. Perhaps a way to report it to the Stack Overflow Blog so that it can be written about in a news story for all to see.
While this sort of answer is more likely on a site like Great Outdoors than on Stack Overflow, I still think it applies to all of Stack Exchange. In a more general sense, life-saving stories like this are the ultimate example of Stack Exchange's mission statement of helping people. I can think of no greater type of success story, and so I believe the reward should be proportionately exceptional.
