Considerable amount of the answers I see which doesn't Quote Quran or Hadith as a reference (don't want to point to any particular question here), I would like to suggest/get feedback on mentioning/enforcing "no direct reference in Quran or Hadith" in answers. I agree that some times we need to inference the answer from something else. But it should not be the first thing to do.
Quran 4:59 if you disagree over anything, refer it to Allah and the Messenger
As a matter of fact, I believe It is better to mention in every answer that "There is no direct reference for so and so in Quran or Authentic Hadith" (if it is actually the case) as the first point before the actual answer.
As Prophet Mohammed (SAL) said in the Last Sermon
O People, no prophet or apostle will come after me, and no new faith will be born. Reason well, therefore, O people, and understand words which I convey to you. I leave behind me two things, the Quran and my example, the Sunnah, and if you follow these you will never go astray.
I believe these statements are inline with the Objectives of ISLAM.SE
