Trying to help a little and reading some meta (hot) posts, I went across this question.
It's a general way to convey some doubts like this one: replying to someone is often a dialectic process, not merely giving a solution. In other words, it's driving the OP to find a solution with questions and tests suggestions in comments (not in answers). What to do when done (when the OP tells "Hurray, thanks a lot" and so on). Most often, the answer exists not, or could be rewritten and elaborated.
- Not important if AU is more a hotline, because the important thing is to unlock the user problem.
- Important if AU is more a knowledge base. Then editing the answers to make them more general and accurate, tagging correctly and so on is important. But this takes time, so is it really useful ?
What's you opinion on this ?
