I still don't know why anyone outside the techospher will ever pay to use app.net. Does a material number of users outside the techosphere even care that some apps are having their access restricted? Does anyone outsidethe techosphere even know app.net exists? More importantly, App.net is still a closed box, just like Twitter. App.net still has to pay the bills, just like Twitter. When faced with the same decisions in the future, what prevent app.net from making similar decisions as Twitter? Will $5 a user per month really cover their costs if they hit scale (I know they have other revenue streams, but I'm guessing they will have more users than anything else)?
