App.net to developers: Give me money, so you can use a Twitter like infrastructure. PS. It's not open-source and you have to pay an ongoing subscription.
App.net to investors: Give me money, in return I will give you equity ownership of the technology we built thanks to the money from developers. Don't worry, the developers don't own any equity so more for you and me.
App.net to Bitcoin supporters: Give me money, blah blah blah.
