Suppose I ask a question which for one reason or another might have multiple valid answers. Maybe it's subjective, maybe it's a problem that could have multiple solutions, maybe there are just different ways to explain the same idea. I get some answers, and one is definitely the most helpful or useful to me, among other good answers. Should I accept it? Or is that bad, because I'd be declaring it to be the one true correct answer?
Note that I'm asking this in the context of StackExchange as a whole, where this is a more common occurrence than on SO. For example, on cooking, a lot of questions can have multiple good answers. Also, I know this is a historically contentious topic, but I'm looking for fresher answers, not pointers to questions from years ago, when we didn't know what to do with subjective questions and didn't have so many diverse sites.
