Some people love commas. LOVE them. They put them everywhere they can put them! Like this:
Some people, love commas! LOVE them, they, put them everywhere, they can, put them!
We have worked on projects for individuals who have PhD credentials, articles and books under their belts. These individuals, some of them, loved to put commas, everywhere.
Never put a comma between a subject and its verb
Commas are not salt. You should not sprinkle them in as if you’ve had too much wine. People will talk. You can probably go comma-crazy if you are writing humorous dialogue for a space alien and wish to indicate many pauses. You can also sprinkle away if you are developing a code for your secret bunker home school’s new cult language. Just remember that reading a sentence embroidered with commas can cause the acid gases of exasperation to build up in the reader’s veins.
What is okay?
That comma some people use before the last and in a sentence (“The 8" high heels, the whips, and the almond oil were ready.”) is also called an Oxford comma, or a Harvard comma, or a serial comma. Use it? Don’t use it? It’s largely up to you. You can also check the preference listed in your organization’s style guide.
A comma before a nonrestrictive appositive. (“We will always adore Paris, the golden goblet of true style.”)
