Heavy use of acronyms or initialisms (strictly speaking, an acronym is a combination of letters pronounced as a word [NATO] and the letters of an initialism are read individually [FMQ - just try to pronounce that as a word]) can be intimidating or alienating to a newbie. One useful technique to avoid this, particularly when the abbreviation is going to be used repeatedly, is spell it out the first time, with the abbreviated form in parenthesis. Subsequent occurrences needn't be spelled out, since the explanation has already been given.
