The big final rule for the comma is one that you won't find in any books by grammarians. It is quite easy to remember, however. The rule is: don't use commas like a stupid person. I mean it. More than any other mark, the comma requires the writer to use intelligent discretion and to be simply alert to potential ambiguity.
