In addition to Russell's answer, there are many occasions where the OP doesn't know what to search for. Think about questions where the concept exists but it is unknown to the OP, or "identify this part / socket" questions.
In such cases, the OP doesn't need to be pointed to a specific tutorial or product, he just needs keywords he could use. Whether the keywords should be given as plain text or in a GIYF link is a matter of personal preference, and neither approach should be forbidden. Consider this:
Q: I have this device, where do I find a connector for it?
A1: This is PCMCIA, check out your local shops or e-bay
A2: Check out your local shops or e-bay. GIYF
Both answers convey an equal amount of information, it's the formatting that differs. If you don't like the formatting of A2, feel free to edit it. Removing it simply because you didn't like the formatting is wasting an otherwise useful answer.
