My First question didn't fall in criteria of Skeptics and was closed. This helped me understand what should be asked here and what should be not. After a week or so, i still see my closed question existing in the database and everyone has access to it other than the ability to provide answers.
Same thing applies to other closed questions. So my question or rather a point is why aren't we deleting the closed questions. In case we need to keep them, then make a weekly deadline; crossing which, the question is deleted itself.
I think the site is enough mature and enough questions to make people understand the real essence of Skeptics. Therefore, the closed questions should be removed from the database for achieving a meaningful and knowledgeable database.
