The original Back it up policy had a standard evaluation.
Does the answer completely answer the question and explain why?
This standard seems to have gone to the wayside. I would like to see this standard revived and applied to answers that do not address the question asked and especially those short answers that basically just express the opinion of the poster. Many times these short answers are popular with the drive by hot question visitors and end up highly voted. This, in my opinion, harms the site.
Can we increase the current minimum standard to every answer must be complete and address the question asked?
