If you get an idea for a post and begin a draft of it, but you don't finish it until after you've posted another piece (or two or three), the draft, when completed, is posted BEFORE the "later" ones. ?!?
A draft, after all, isn't a posting until it's posted -- no matter when it's begun!
And it should be published in the order it's posted.
In other words, if you're interested, there's something newer on the blog here than the last several posts.
