The primary reason for closing a question is to stop it from receiving new answers[1]. We are telling the question asker and potential answerers that the question is not ready yet to receive new answers or that it cannot be answered here at all. It has been very useful in keeping the site clean over the years. But is it still useful?
It's no secret that Stack Overflow has almost stopped receiving new questions. The current volume is easily manageable by the remaining curators on the site. The number of new answers has also proportionally dropped. It doesn't feel like closing questions actually helps with keeping the site clean anymore.
For as long as the site existed, users have complained that the most toxic part of Stack Overflow is the question closure. We have defended it saying that it is crucial to maintaining high quality of questions and answers on the site. The "toxicity" was just something that users would have to suffer through for the greater good. But if closing questions doesn't help in keeping the site clean anymore then it remains only to punish users.
This meta post isn't about proposing any new rule or change to the system, but rather to start a discussion. Do you think the current system of closing new questions is still useful? Do you think it should be reworked?
FAQs:
Concern: Closing questions gets them deleted after some time.
A: And so will unanswered questions. If a question cannot receive answers, then the system will remove it automatically, too.
Concern: Closing prevents bad answers from new users.
A: Historically, mods never accepted flags about wrong/low-quality answers because we cannot judge their correctness and the volume would drown us. But 20k+ users have answer-delete votes and they can use them on poor answers. With limited number of flags, mods probably wouldn't mind an occasional flag about a totally rubbish answer.
Concern: A closed question offers guidance to the user on how to improve the question.
A: People who cared and asked the question to the best of their effort and still got it closed, probably wouldn't be able to edit it even with the guidance to get it reopened. Those who didn't put enough effort, probably couldn't be bothered to read and apply the instructions. We can offer personalized guidance to the askers now that the question volume is down. If something can be improved in the question, we can just say what in the comments.
