There seems to be an inherent tension between, on one hand, providing an ask-question wizard that will actually help homework askers with asking their question in a good way, and on the other hand not giving the impression that homework help is what MSE is for.
The really good questions that we always want and need more are not about homework. They would be ill served by being shoehorned into a homework template -- or worse yet, the person with the question could get the idea that his question is not welcome here because it doesn't fit the template.
(The basic difference is that homework questions are asked by people who in principle ought to know enough to solve the problem by themself. Answering such a question -- other than with a ready-to-hand-in solution -- requires figuring out which particular piece of the knowledge the asker should have they are missing, hence why we keep asking for own work, failed attempts, etc. This is different from really good questions, which are most often asked out of honest curitosity and there is no expectation that the asker can do any work to show. On a general, abstract level, it is still helpful to know which level of previous knowledge the asker has, but it is hard to ask for that with template prompts that are also practically helpful to the homework asker).
I played around a bit with the SO feature. It starts out very promising, with a "what type of question do you have?" multiple-choice prompt. Unfortunately it looks like the only thing the answer to that is used for is suggesting other sites to ask at for some types of question. When you get through to the actual question template, it is the same no matter what the initial type selected was.
