I still feel that the idea of deleting a story and republishing it, can be a risky endeavour. In many cases depending on the time frame since the original story was written, it would probably be more beneficial to write a new story taking a different point of view or entirely update the story that it appears to be a new story anyway and not bother with deleting the old story. Every time you delete a story you potentially create a dead link somewhere else and leave a potential reader unable to find you. Because almost every reason for deleting an article falls back to attempting to game the system.
