I tried looking around on the FAQs and in previous Meta questions but couldn't find something directly answering this question.
I have seen some answers to questions which provide NO actual answer but simply links to articles. Now these articles may indeed be useful to solve the problem. However, to me this signifies little effort on the answer. I understand there are instances when an exact answer isn't applicable and articles may put them in the right direction.
Should links be provided just as citations to backup your answer? To expand upon your answer? Or to say "just go look at this"?
