I suppose you have seen an About.me page before, but if the concept is new to you it suffices to say these are personalized pages in which you can tell the whole world about who you are and what you do. Well, I want you to take that concept and make a substitution: take away the human element (IE the person that the page is all about) and have that replaced by an actual mobile application. If you do that, you will have a service identical to App.net in your hands.
App.net enables developers to build up presentation pages for their mobile apps. These can include not only descriptions and images but also download links. And not any kind of download links at that, but intelligent buttons and widgets that can bring any marketing campaign to life.
And I mean it – all the pages that you can create like this come complete with full analytics. Figuring out who has visited it and become interested in what you have developed could hardly be any clearer or more immediate.
