I'm really trying to understand app.net, I used it for a little while and browsed the apps people had made for it but they all just seemed like mobile and desktop clients to send status updates to alpha. It also seems as though you need an app.net account to use an app built with their API which seems very limiting to me in terms of the type of markets you can reach. What's the incentive for someone to use app.net's API over something such as hull.io?
