All possible sites given by this answer are very disappointing in dealing with question & answer and the Physics.SE is by far the best (with respect to design and with respect to active users ) so I should ask two questions.
- Why there is such a rigorous policy about homework questions and way this type of questions cannot live among other conceptual and more advanced questions?
- Usually, reading the discussions here we get that more advanced researches don't want people to ask 'bad' questions, but the edit possibility shouldn't be used to teach how to ask a good question?
- Why exactly homework-like questions should be deleted? This types of questions are very instructive to high-level research and they are the basis of our teaching standard methods in the world. Even graduate students have tests and questions-type approach's.
Then I'm thinking if it is not possible to have a less-rigorous policy on the homework-questions, even destroying the tag and leaving this type of questions on site for (i) future students (ii) future doubts on the same questions. Creating a tag for 'do this is correct' it is also important.
It is important to see that we should delete duplicate questions and questions that do not show effort on it and for homework question keep presenting just hints and not the full answer but, the way this site is, I think users deleting questions on physics of new users with such a rigorous approach is just killing the site and making more and more a site just for very high level questions that remains unanswered most of the time.
I think changing the policy would bring more people to study physics by their own and more advanced research level professionals in order to answer questions on the site.
