Even through some basic "rules of thumb" likely apply, genealogical problems are specific. If questions are asked in context (the problem I'm facing is ...), we have the opportunity to solve "real problems" rather than just referring folks to the big book of basics.*
Said another way, if the question posted provides the information and/or insight into record, family and personal circumstances at hand, I tend towards allowing the questions to be answered. (I realize there is some art involved in tagging these "somewhat similar" questions, so that all can be located.)
I hope @ACProctor weighs in on this, as he has separately expressed some related good ideas.
*P.S. Consider that even the big book of basics often doesn't come to be very meaningful until you have a fair amount of experience. Ala, until you can relate to just why this or that is even a basic.
