I know this topic may be better situated in the Marla's punctuation subforum, but I thought a discussion of it might be something that could be useful in the main forum. Plus, I would like to learn the opinions of others: seasoned pros, students (what they're teaching you in school about this topic, if anything), proofreaders, scopists, transcriptionists, and veterans in the indusry.
I have strong feelings about commas. In recent times, I have expanded my network of folks that I work with, and it seems that there's a school of thought that swings both ways on the serial comma.
Example A. I bought apples, peaches, and pears.
Example B. I bought apples, peaches and pears.
Please follow up on this thread with your preference of the serial comma, as it will help me provide a follow-up to my work associates.
TIA to any and all responders! :-)
