This is a thought that came to mind after seeing the daily couple gaming questions that come into SU. If the rules state that most gaming questions are not within the scope of the site, why don't we just delete those questions instead of close them and leave them laying around?
Valid point. However in the past some questions have been re-opened and allowed. Even Jeff himself closes them and doesn't delete them. In some cases there are a very gray area and other moderators may decide to re-open a question if they feel it is valid.
I have been under fire a lot lately for closing gaming and phone question irrelevant of the content, as I believe keeping just one question open makes it extremely hard to enforce a rule when others ask similar questions. This is becoming a very heated debate at the moment.
