There are many things that can (and will) drive an editor batty. Punctuation just happens to among them. There is much confusion about punctuation. Often writers get them confused. Hell, even editors get muddled at times.
Today, I wanted to address the importance of the comma.
I will grant you that there is a significant amount of debate over the usage of commas, particularly the Oxford comma (whether we should or shouldn't use it). It probably doesn't help that the Oxford comma has now won a legal court case.
However, many editors will agree that commas seem to be disappearing from text, partly because of the increasing usage of smartphones and social media. This, folks, is not a good thing. I will grant you that when writing a hurried tweet, the comma can consume precious character counts. However, one little comma can change the entire meaning of a sentence. It can mean the difference between being a cannibal or a time traveller.
