Give this badge for
- having
{some number of}of the following:- a
{good enough answer}, - to a
{fair competition question}, - which have no competing answers
- a
Some measures are :
{good enough answer}: acceptance or upvotes or a combination thereof.{fair competition question}: age(see note) or number of views or a combination thereof.
Essentially we want to reward those who've provided non-garbage answers to questions which for one reason or another no one else bothered to answer. Maybe it's too hard, maybe it's too boring, maybe the topic/technology is too niche/obscure, maybe it's just a bad question not worth answering(see note), maybe the question is already adequately answered and there's no point in providing an alternative, etc.
The question has to allow for fair competition. The emphasis is not in being the first to answer the question; it's about being the only one to answer the question, despite ample chance for others to provide alternative/competing answers.
Notes:
To clarify, it's not necessary to provide a new answer to an old unanswered question. The answer itself may just be as old as the question, so in that sense this is not a dupe of {Necromancer}.
Also, one reason that there may not be a competing answer is perhaps because it's such a bad question that no one else bothered to take the time. In that sense there's similarity with {Reversal}, but where as {Reversal} really rewards "good" answer to a "terrible" question, this badge rewards being the only one to answer a question, regardless of the quality of the question.
I'm going to guess that most scenarios that are eligible for {Reversal}, aren't eligible for this badge.
{some number of}non-garbage answers (say, 10?) to earn just one. (ii) each user can only earn at most one (simplifies many things, and I think in line with other badges of this style).
