Linking is not a bad thing as long as you actually provide some context to your answer. If all you are going to do is post a link in your answer, you aren't really answering, you are just providing a detour for the user. At the very least you could explain where the link goes and what it is going to show the user (maybe even quote some of important stuff in the answer so that the OP doesn't have to click the link to possibly answer their question.
