Before asking the question I searched through Meta and found only this topic that seems to be a little bit outdated and not directly addressing my question.
I am not new to StackOverflow, but sometimes I have questions where I am not sure what site they should be posted too. I did read the FAQs of the most common technical forums like SO, Programmers, Code Review, Code Golf, Superuser etc, but I have never seen more or less an algorithmic/objective approach to defining if the question is suitable for the site or is rather an off-topic.
Of course I do understand that is not at all easy (if possible at all) to formulate the criteria in an objective and non-ambiguous way, but it would really help to see:
- Some typical questions that are welcome in the community/forum.
- Some (best if point-based) criteria for good question: quoting own source-code (let's say, 3 points), providing a web reference (1 point), providing own (eventually not complete or fully correct) approach to the problem etc.
- Some typical off-topic questions with negative points, like: rhetorical question, no efforts done to find a solution on your own etc.
It would be also nice to have a kind of a sandbox for questions where everyone could post and then more experienced SO users could just move it to an appropriate technical (or non-technical) Stack Exchange site or close it altogether.
