Where is the line we are drawing here?
The former has no code sample, which I assume is why it was spotted as not being relevant to CodeReview. The latter has a code sample but it really offers nothing to the question, except clarification.
I am perfectly happy with going in a different direction from StackOverflow and saying that questions should be specific rather than vague, containing an actual and complete code sample, but we should have a clear line and stick to it.
