We're also using a very open development model - most of the code that runs our apps is MIT licensed and easy to use elsewhere: https://github.com/rundexter
Having some loose set of code repos up that claim to "run your apps" is no excuse for not having a sustainable and publicly scrutinized revenue model for the project. Without a model in place, savvy users (like those here on HN) will realize that your model may change later (because the VCs require you to exit for example) and that will affect how we get along holistically with your product later.
