I have been going through the unanswered questions list of this SE and was surprised to see how many of the questions were actually answered in the comments. The commentator then virtually abandons the question and it kind offkindof stays forever unsolved. Why do they not simply post it as an answer?
Alright yes, maybe they wanted it to be more detailed. So would it be a good practice to take one these perfectly good comments (maybe add a point or two) and addpost it as your own answer?
