It seems that some of the community here is rather hostile to new posters who don't know exactly how "professional" a question has to be in order to be accepted here as a good fit.
For example, this one I just asked. The initial question form made the the mistake of relating it to a "home dev" environment, which upon clarification, was off-topic in and of itself, but the the heart of the question certainly seems like it might be applicable to "professional system administration" and while the answers could be subjective (e.g. "I have never experienced any issues, but have no technical basis for saying this...") the original form of the question wasn't searching for subjective answers.
So -- should there be a list of "off-topic" item examples for tricky questions? Furthermore, since there is no "real issue" at this time - only potential issues in the future - how would this affect the trickiness of the question? How should it be be "explained" that potential problems aren't a good fit for this QA forum?
