At one point we want to attract more people to this forum, at the other point there is a very restrictive policy regarding closing question. In my opinion these points are contradictory to each other. I was amazed that this question: Which of these airports is the most interesting for a pilot and this question was not: Whats the deepest underwater tour available
I can think of other questions that are similar in asking and remained open. I really wish travel.SE would allow a broader set of travel related questions.
Compare it to stackoverflow, the mother of all current stackexchange sites. Every type of programming questions are hosted there from prolog, java, c, php, etc.
