I've gone through the threads on the Oxford comma and I am wondering why it is a stylistic choice rather than a standard practice, particularly with 3/+ items connected with "and"?
My point of contention is that since it prevents confusion (as agreed by many on the forum, many posts point people to this response) and thus, providing precise meaning, why isn't it considered a standard practice?
Adding a CNN article here saying that the lack of an Oxford comma cost a company USD$5 million to prove my point.
