Yeah, I give a fuck about an Oxford comma. I'm for it, unless it introduces ambiguity, in which case I'd rephrase the whole thing.Wikipedia wrote:The serial comma (also known as the Oxford comma or Harvard comma) is the comma used immediately before a grammatical conjunction (nearly always and or or; sometimes nor) that precedes the last item in a list of three or more items. The phrase "Portugal, Spain, and France", for example, is written with the serial comma, while "Portugal, Spain and France", identical in meaning, is written without it.
If you don't always stick to a particular style, as many don't, vote for the one that you would choose if you had to stick to one or the other for all cases.
