Well, start waving and yelling, because it is the so-called Oxford comma and it is a lot more dangerous than its exclusive, ivory-tower moniker might suggest. There are people who embrace the Oxford comma and people who don't, and I'll just say this: never get between these people when drink has been taken. Oh, the Oxford comma. Here, in case you don't know what it is yet, is the perennial example, as espoused by Harold Ross: "The flag is red, white, and blue." So what do you think of it? Are you for or against it? Do you hover in between?

Punctuation marks are the traffic signals of language: they tell us to slow down, notice this, take a detour, and stop.

Brackets come in various shapes, types and names: 1 round brackets (which we call brackets, and the Americans call parentheses) 2 square brackets [which we call square brackets, and the Americans call brackets]

After university, I got a job sub-editing and for years I was a literary editor.

Old radio comedy makes me laugh, as well as 'I'm Sorry I Haven't a Clue' and comedians like Paul Merton.

The reason it's worth standing up for punctuation is not that it's an arbitrary system of notation known only to an over-sensitive elite who have attacks of the vapours when they see it misapplied. The reason to stand up for punctuation is that without it there is no reliable way of communicating meaning.
