These questions can be difficult to ask - not only do they need to be clear, concise, and specific but they also require a significant amount of context - not an easy task! And not one that the underlying platform is geared for IMO - especially when the user may not know what exactly the issue is or where it is coming from.
I overheard this the other day in chat: often is the case that users ask the WHY without knowing the WHAT (Why is XYZ not working? vs first understanding WHAT is XYZ?) - this commonly leads to questions formed with improper context and the community "shooting arrows in the dark" as to what the answer could be. There is almost always a need for clarifying questions and additional info for the question to fully develop into a question that can be solved by the community - back-and-forth for these types of questions is essential. In this in-between period where the question is still being formed, there tends to be noise (other users guessing what the issue could be) - which creates a bit of a messy UX.
Although there have been cases where the user does ask a complete question in a clear and concise manner with the correct context e.g. logs, node config, etc., even so I notice that the question becomes "bloated". I don't think Stack Exchange is the best place to have these types of questions which lead into nested inquires e.g. what version are you running?, did you update to latest?, are you running XYZ?, try this, etc. but then again maybe it is the best place because there is no other better suited place for these types of questions to be asked?
I think Stack Exchange is great for "HOW" and "WHAT" questions but may not have the "deeper" UX to appropriately solve "WHY/WHAT" or "WHY/HOW" questions e.g. "Why is XYZ not working? AND how/what do I need to do to fix it?"
Even so, I have already seen value generated from these types of questions. For example, take a look at these posts:
The troubleshooting tips presented in these questions are a treasure trove of knowledge and they are indexed by Google! Even if they do not solve that user's issue they are valuable for others who stumble upon a similar issue. But then again is the platform being used in the appropriate manner?
