When you publish your story you will notice that on the LivePost app it is ordered in chronological order (the first updates at the top, newest updates at the bottom). You will also notice that when you visit your Live Story online, it will appear in reverse chronological order (the newest updates at the top, the first updates at the bottom). The reason for ordering them in reverse chronological order is that most people who come to your story will prefer to see the latest updates at the top.
