Actually, doesn't YC suggest you not incorporate when you partner or launch so that if you apply for and get into YC, they can help you form with their preferred structure?

Someone is going to have to show me an assesment of the true liability exposure of a website with no personally identifiable user data, no financial information, and presumably no personal assets to collect against before I'm convinced that's not a perfectly sound initial plan.

We formed a partnership agreement, no incorporation, FWIW. The agreement is binding.
