Cornbread has two schools of thought: Sweet, and not so sweet.

This, definitely. I've been taken by unpleasant surprise when my cornbread is not sweet. It's not that I don't like it that way, it just comes as a shock if you're expecting the sticky sweet stuff and you get something that's almost bitter in flavor. I've been told that the "old fashioned" cornbread is not sweet, which I suppose I'd believe, and often eaten with honey or molasses. Tried it, it's not too bad, but... my gut tells me that you wouldn't like it much.
