…Especially in lists of three or more items.
True. Now that I think about it, I seem to recall that Strunk and White makes a similar point, allowing a comma splice for phrases presenting a certain poetic rhythm. I think the example it gives is “Man proposes, God disposes.”
But to circle back to the OP, I’m still not sure that a comma splice, which is a special case in any event, is a good example by which to evaluate the need for a serial comma.
I find it annoying when people don’t use the serial comma. I also think that semi-colons are underused in modern writing.
Agreed; though I think I overcompensate for society as a whole by overusing them when I write.
