re: Grammar Q: Use of commas in lists

quote:

---

Most who went to a catholic or college preparatory school were taught to use B, without the final comma.

I don't recall from the two years I was at one. But that's a bad thing to teach because it's confusing and wastes time.

quote:

---

Journalists typically are taught to write using the AP style which uses the extra comma.

Incorrect. AP style teaches to use without the Oxford comma. I think to theoretically save space, which is fair.

I’m an advocate of the Oxford comma. There are some instances where it can help clarify a sentence, so I prefer to use it in all instances.

depends on what style you are using; Associated Press style calls for NO Oxford comma;
