here's a worst kept secret:
for any question that is not today's question of the day,
the answer is in the newsletters:
so if you were looking at the QOTD for Monday, 11/12/2012, if you look at the Newsletter for Tuesday, 11/13/2012, you can see the answer and the explanation without directly answering the question.
For a Friday QOTD, you have to wait for following Monday Newsletter, but it's there too.
