It's highly presumptious to assume you know better than the person asking. You might, but you might not. The fact that SO serves as a collection of programming knowledge, you do not know better than everyone who will ever search for that question even if you do actually know better than the OP who actually asked the first time.
It would be fine to help with all these other possibilites but part of your answer should... actually answer the question that was asked, as it was asked and not doing so should result in a servere punishement.
