90% of all iOS apps in the App Store are downloaded every month (allthingsd.com)

I always assumed that if I wrote an iOS app that no one would ever see it except a few friends.

Question: Should this be taken as a positive sign that you can still get word of mouth momentum on a new and useful application?

From the context I understand, it was 90% of iPad iOS apps are downloaded every month. There are far fewer iPad specific apps than overall.
