Why is my post order screwy?

This is peculiar...  My post order for the first three entries is wrong.  At the top is the first post I wrote using the web interface, then it's the second email test post, then finally the first email test post.  I thought blogs generally sorted with the newest post on top.  So, why is the oldest post on top, followed by the newest post, followed by the middle post last?  Bizarre.

This post is simply to see where it ends up in the list.
