Oxford, birthplace of the Oxford Comma.
What exactly is the Oxford Comma, you ask? For some, it is a vital piece of punctuation — never write a three-or-more item list without one. For others, it is an ugly and useless stop sign getting in the way of your reading.
I grew up using the Oxford Comma — that final comma before the conjunction (e.g., and, or, but) — then unlearned it years later at journalism school.
The debate over its necessity continues, and I suspect always will.
What do you think: Is the Oxford Comma a must, a must not[,] or up to the writer?
