I have only recently come upon this stack site. While I enjoy the subject of finance, particularly investing quite a bit, I think the subject is a bit of a departure from other Stack sites I have visited. In StackOverflow or SuperUser, questions are quite objective. There may be a few ways to approach a programming problem, but in the end it's easy to see that they work (or do not). In personal finance, there are a whole slew of questions that can not be definitively answered. Particularly those questions that involve predictions of the economy or a certain investment. The thread for those question could just go on and on with no definitive answer in site. Some of these questions (where is Stock X going?) may be the most interesting to people. This seems contrary to the general intent of stack site, which is to avoid unanswerable questions.
There are plenty of answerable questions. What is a stock, what is a bond, what are the tax advantages to investment X, what is the difference between types of mortgages.
What is a good way of sorting unanswerable questions from answerable ones. If we allow 'unanswerable' questions, isn't that a departure from the philosophy of stack sites in general?
