Although specialized vocabulary and acronymization is part of all professional fields, I believe that in general questions on StackExchange, and especially Area 51, could benefit from using language that is accessible to as many people as possible.
What guidelines could we use for when to use an acronym vs. write out the phrase?
Another perspective is that if an individual is not knowledgeable enough to know the acronym, they are probably not knowledgable enough to answer the question.
