So, it looks like someone has taken up the task of calling out some of the truly terrible Windows 8 Apps that are getting into the Windows 8 App Store. Examples include trivial "games" submitted dozens of times under different names, rebadged SDK samples, and my personal favorite: App13.
I myself have seen quite a few apps with the default template gray background and box-with-an-x icon. And no-one should go wanting for a unit converter app on Windows 8. Is MS going to crack down on this tripe?
