Not to criticize but that is, or should be, bog standard in any writing. (Assuming the acronym isn't widely used and the words that it embodies essentially a trivia contest answer).
I don't care how widely used the acronym for a noun is, first use should always be the full form.
Only time I don't think it should be applied is in the case of a standard/protocol, or policy (such as gif or VAT). Then the first use should be the concept explained, not what it stands for.
I do like their style-guide definition:
acronym: A pronounceable word, formed from the initials of other words, like radar, nimby or NATO. It is not a set of initials, like the BBC or the IMF.
One example is the amount on comments here on hn about some acronyms thrown without explanation. There are, for instance, 1200 matches for 'What is IC' (Individual Contributor)
