This question is not about whether add-ons should be discussed on our Stack Exchange site (I think we probably all agree they should!). It is more about the type of questions.
It seems like the push, at least on Stack Overflow, is for questions that are specifically about programming, would be likely to generate an answer that is of use to the community at large, and would have lasting value. On Stack Overflow questions that don't meet those critera are sometimes closed as "too localized:"
This question is unlikely to ever help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet
Or they are sometimes closed as "off topic:"
Questions on Stack Overflow are expected to relate to programming or software development within the scope defined in the FAQ. Consider editing the question or leaving comments for improvement if you believe the question can be reworded to fit within the scope. Read more about closed questions here.
It would seem that some "product support" type of questions (specifically, non-technical questions about EE add-ons) could potentially fall into this category, at least on Stack Overflow.
With that in mind, on to my question
What kind of product-support questions should be allowed on the EE Stack Exchange site? Is there a place for any/all of types of product support questions on the EE Stack Exchange site? Or is a separate product forum a better place?
For example, consider a couple questions posted on Stack Overflow which were closed as "off topic" or "not a real question"
Should the ExpressionEngine Stack Exchange site allow questions like this? What type of guidelines about questions like this should we have in our FAQ?
UPDATE: Also see the more specific question, Should we be directing official add-on support here?
