A few points that she makes are:
"The words can connect words, phrases or clauses. They are called coordinating conjunctions because they join equal things."and
"Newspaper style varies from academic style on commas and items in a series. In newspapers, we drop the comma just before the coordinating conjunction:finally
Stir in sugar, oil, beaten eggs and vanilla."
"You have probably heard that you should not begin a sentence with a coordinating conjunction. Piffle! You shouldn't begin every sentence with a conjunction, but you can use the conjunctions sometimes. But don't put a comma after the conjunction."
I found a few things interesting in her discussion of the FANBOYS. I liked that she pointed out how journalistic style is different from academic style. Second, she points out that we can use a coordinating conjunction at the beginning of a sentence. There is no rule that a sentence cannot begin with a coordinating conjunction, but there are some teacher rules that forbid the use of coordinating conjunctions at the beginning of a sentence. Finally, remember the final sentence I quote above:"But don't put a comma after the conjunction."
By the way, for those who do not know, according to Merriam Webster's on line, piffle means "trivial nonsense".
