What to do when a question just wants a yes/no answer.
In the case of this question of mine, the answer was a 'yes' or a 'no - and here's why'. In the case of questions with the proof verification tag, I suspect this is standard. This means that if the proof is correct we get just a 'yes', which is the case in that linked question. Now I had read on this meta somewhere that the correct action to remove this from the 'unanswered' list is to merely throw a community answer onto it. This is what I had done, but it was deleted.
1) Should proof verification questions be formulated in some different way, i.e. "Is this proof correct, is there a better proof?". One problem I see with this is that it opens up duplicate tagging immediately, when the primary question is, "is my proof correct?".
b. Is it acceptable to post 'yes' as an answer, and should this be a community answer?
iii - Do proof verification questions not really fit the purpose of the site in the first place? It seems that they are a way to avoid duplicates and they do primarily cater to the user at hand. I can see them promoting interesting answers in the case they are wrong, but if a user is asking for a proof verification, they most likely do have a valid proof, or alternatively, they are either being lazy and not rigorously checking their own proof or they lack confidence in their proof, which they should be able to mitigate by thinking about it more and combing over it.
