Should questions contain quotes if they refer to external sources?

Question

In this particular case I am referring to Treating independent code as a function in IDA Pro (and I don't mean to make this a pillory at all!)

Original (full) answer as of this writing:

This is probably off-topic but it sounds like what you need is node groups.

On other SE sites I have often found moderators and other community members pointing out that external sources should be quoted with there most vital statements. This is what I did on Igor's answer, too. Likely reasoning behind this is that if the external link goes stale, the person trying to locate the new location of that information will have it more easy to find what is needed.

You could arguably take at least two sides:

• this is redundant
• essential parts have to be quoted to provide context

Which is it for this SE site?

Answer 1

We should follow the network wide policy on link only answers and not try a different approach as the reasoning behind this policy is rather solid (which you yourself have pointed out).

Quoting the relevant parts :

I think that links are fantastic, but they should never be the only piece of information in your answer.

When someone goes on StackOverflow, the question "answer" should actually contain an answer. Not just a bunch of directions towards the answer. You should provide context to all your links, otherwise the OP will have no idea what they are clicking into.
