commas

Every few years, the powers that be change grammar rules.  Between 9th grade and the end of college, I think MLA format changed six times, and that is just one example.  The latest example that is driving me crazy is the lack of a comma before the "and" in a series or list.

Previously, we would write: "Today I woke up, read a book, and ate cereal."  Now it is written this way: "Today I woke up, read a book and ate cereal."

Here is a blog post that answers the reason why I still prefer the first way (in addition to the fact that I resist change at all costs):
