Ask HN: Using startup processes for creating a nonprofit

Does anyone know of any resources that talk about how to reuse the processes used my modern startups (lean, agile and what not) for creating a new nonprofit?

I imagine that such information must exist out there (especially at a time when wonderful initiatives like Watsi are supported by accelerators such as YC) but my searches haven't resulted in anything concrete.

Backstory:

I am working on a web-based educational resource that helps students learn topics in applied mathematics and computational science. I would like the resource to be freely accessible to anyone interested, while still offering material of good quality and usefulness.

While I have enjoyed working on this full-time and have learned a lot in the process, I'm afraid that living off savings is not a sustainable strategy in the long term. :) I am therefore hoping to build a sustainable nonprofit around my initial efforts.
