Suddenly, First Entry Displays First

Used to be my blog entries showed up last one first–in other words, in reverse order. Now, all of a sudden–started Wednesday night–the link to my blog, http://www.tianodesign.com/blog, brings up my very first entry. All the time.

Any ideas why? I’ve done nothing under the hood. Hadn’t even made an entry in about two weeks because I was away on vacation.
