Have you ever advised your friends not spend their time on Qs they have no answer for? See detail.

Or have you been advised to not waste your time unless you do have the answer. I mean why waste their hopefully valuable time on questions they have no answers for? Aren’t there enough questions that are waiting to be answered (esp. asked by their friends’ if they have any on the site)? This question can’t be answered is not an answer since very soon after that post, someone would answer it.

Don’t they have questions to ask, and to respond to the answers they get? Why do they devalue their time so much? The texts are long and seems to have taken a long time to compose, but there is no answer there.
