A notable problem on this site seems to be PSQs from new users. In order to encourage better questions, I suggest implementing a fill-in-the-blank type structure for new users asking questions. Once a certain reputation is achieved (for example, 150), the system can revert back to the standard question interface. The following is a rough sketch of what the new user interface may look like:
Title
Make your title your question; use it to convey as much information as possible. Don't be afraid to make it long.
[Space to add title]
Question Statement
Write the statement of the question, including all assumptions and conditions. This may be the same as the title.
[Space to add question statement]
Source/Motivation
Mention where you came across the question and/or what prompted you to ask about it.
[Space to add source/motivation]
Background (optional)
Indicate your level of familiarity with the question topic.
[Space to add background]
Definitions (optional)
Define any important terms relating to the question.
[Space to add definitions]
Your Work
Include your thoughts, observations, research and/or attempts to solve the problem.
[Space to add the OP's work]
Other (optional)
Add any additional details relevant to the question.
[Space to add other details]
References (optional)
Link any references appropriate to the question.
[Space to add references]
Tags
Add up to 5 tags to describe what your question is about.
[Space to add tags]
The question can then render as follows:
$\large\text{[Title]}$
[Question Statement]
Source/Motivation
[Source/Motivation]
Background
[Background]
etc.
After the question has been posted, the OP can edit the question using the standard interface, thus being able to reformat and restructure the question if necessary.
Happy to hear feedback on the same.
