Should we downvote duplicates?
I posted a question which was down voted as people say the concept is not good for Q&A sites. I supported them. The question was then closed as there are possible duplicates in this site.
My question is why the question was not deleted as already duplicates are present and if in future such duplicate questions arise they can always cite the same links link1 and link2 which was posted in the previous question as original posts. Now people say there are need of closed questions (closed for being duplicate) because they can be reopened by editing.
But I think there are questions which should be deleted rather than closing.For example, the same question can't be improved any more because the idea is not going to work.So I suggest to delete this type of question. Also the poster can't delete them before 30 days because it may harm them.
