MetroStore Scanner (MSS) indicates that the Windows Store has passed the 50,000 application mark. MSS, an unofficial tracker, has been generally accurate in the past. That said, treat the 50,000 number with caution, and keep in mind that not all apps will be available in your area. The growth of applications present in the Windows Store is a key metric by which we can measure developer interest in Windows 8, and the general health of the operating system itself. Naturally, the number of apps in a marketplace do not indicate its total worth; the quality of the applications in question is a key factor by which any platform must be judged. The quality of applications in the Windows Store is quite uneven. The most recently submitted apps, though, are nimpressive, to say the least. Thus, the 50,000 figure is a nice and neat number for Microsoft to have crossed, but the company’s filtration system isn’t catching much dreck, it appears.
