Have you downloaded apps from the App Store and forgotten all about them?
If the answer is affirmative, then it looks like this new tweak in iOS 6 is just for you.
When you download and install a new app from the App Store, iOS 6 labels them “New” as you can see in the screenshot below.
The label disappears after you’ve used the app for the first time. So it seems to serve as a reminder for users that they have not yet used the app.
What do you think about this tweak in iOS 6?
