A lot of time before answering question on StackOverflow, we spent some time asking for clear objective, stack, exact exception message and also reviewing tags.
I would suggest that if a question submission fields can be created like:
- Objective/What to achieve
- Issue/Exception that occurred (along with line) [Optional]
- StackTrace [Optional]
- Additional Details
This way we may save time and can answer question with good details.
In this way we would also restrict the type of question. Because if they don't have such information than it might be design/review question that must be posted to programmers.stackexchange.com or codereview.stackexchange.com
