You’re not a very effective communicator if everyone has to Google what you are taking about. Somehow I am supposed to know what every series of letters means. I was always taught to explain abbreviations before using them.
However, it's considered a common courtesy to the reader to begin an article by spelling out the full name (sometimes with a description or explanation) before referring to it by an abbreviation or acronyms.
