I posted 3 different answers to a question and was prompted in a comment to combine my answers. I do not see any benefit to doing so as the answers are different, not necessarily complementary and I believe can stand on their own. Furthermore, any one of these answers could be marked as "accepted" by the question's author, while if they are combined, the single answer may not be selected even if it has the most desirous material because material in another solution within the answer may not be desired by the question's author.
However, I have seen many answers on this site which cite multiple solutions to the question all within one answer as opposed to breaking them out as different answers.
I would like to know if there is any benefit, convention, or other reason to combine answers as opposed to listing them separately.
