I’ve always been a huge fan of serial commas, even before I knew what they were. It comes from growing up reading older books that all used serial commas religiously. There is a push by many to eliminate them as “unnecessary” and I disagree. It makes comprehension less clear for the reader. I’ve seen many examples of this, such as the classic apocryphal book dedication lacking a serial comma–”I’d like to thank my parents, Ayn Rand and God”–but this example adds a good visual element to drive the point home. Thanks to whatever uncited soul did this picture, btw; I found it on FB and I will gladly provide full credit and links to whomever did this in the first place.
