Thanks, I hate it.

Oh good point. When you nest something into commas like that the sentence is supposed to still make sense when you remove the bit between the commas.

The irony being that now people use ellipses to mark a sentence pause, which isn’t really how an ellipsis is meant to be used. They were supposed to be for removing unnecessary but implied language from quotes. Agreed on the oxford comma though.
