This is such a good point. You see so many new questions where the way the question is posed shows a fundamental misunderstanding that prevents the poster from finding the "trivial" answer they seek.

Just look at the number of "I don't quite understand your question. Do you mean <topic x>" comments that end up assisting the person without providing an explicit answer to their original question. I think that's largely due to answerers feeling that the useful response they are providing is not fit for filing away in the library.
