How are the Answers organized in the "Answers I've Given" section of our profiles?

I thought they were listed in chronological order, but then I noticed that a recent answer I gave is on the front page of my Answers I've Given, ahead of many older answers. So what gives? Does anyone know what actually determines the order of the Answers in that section of our profiles? I don't NEED to know, of course... but I'm very curious! :)
