Before you judge me as some kind of 'anything goes' language heathen, let me just say that I'm not against usage standards. I don't violate them when I want to sound like an educated person, for the same reason I don't wear a bikini to a funeral when I want to look like a respectful person. There are social conventions for the way we do lots of things, and it is to everyone's benefit to be familiar with them. But logic ain't got nothin' to do with it.
