This is very cool, and I really look forward to the future of the project. Have you thought about formalizing your API spec as an RFC? I generally think that the future of data is to allow complete access to all of your data on user programmatically, and this looks like an amazing tool that would help organizations accomplish exactly that. For example, a user story could be "I want to access then delete all of my comments on Facebook", or "I want to build an application that lets users view their data on Facebook as if it were an Excel spreadsheet".
