Sometimes we add things early that aren't released that day. Just because you see something pop up in the item directory doesn't mean it's going to be out immediately. I personally add things for testing purposes, for events, for melody, etc early sometimes. Sometimes in case of challengers, the battle admins get on at one time so I give them items/images and then we get the programming done or whatever later.

and I favor doing multiple posts throughout the day in some cases because it gets people back on the news page. While you might enjoy a long post of everything for the day, some users prefer smaller posts. Some people hate scrolling, so people hate multiple alerts. We're never going to make everyone happy.
