Would it be a good idea to have the capability to directly link to a specific answer? Sometimes when answering questions, I would like to link to another questions's answer, but it isn't always the accepted answer.
A good example is this question. The accepted answer has been up-voted, but there is another answer that goes into much more detail (and has a lot more up-votes). It seems that the more up-voted answer has been more helpful to people visiting the question after the initial accepted answer.
So, when answering another question, it might be nice to reference just the more detailed answer. In this context, it wouldn't be correct to name the new question as duplicate because the context of the question is different.
