I’m little late to write about this, but David Smith has written a great article about how Apple could improve the App Store. This suggestion seems really important to me:

Lastly I’d love to see the variety and specificity of categories you could assign to an app be expanded. The current metadata assignment into one of only 24 categories seems paltry when trying to catalog over a million individual apps. I’m sure based on the search data that Apple has at its disposal they could subdivide of the existing categories into several useful sub-categories (much like how games are treated). This would also help improve the relevance of the top charts. Being the top app in a more niche sub-category might be genuinely useful for developers and customers alike.

I know a ‘contacts’ category would really help Mingle’s sales, and I bet most other apps could also benefit from such a system. WWDC is just a few weeks away. I’ve got my fingers crossed.
