I think it's interesting you're publishing your data, and I'm glad you're happy with what you're publishing -- it totally makes sense. User-defined privacy is an awesome thing.

It remains my proposal that you consider actually cutting off your own access to customer data unless they decide to publish it, essentially extending that ability you have while in control of the system to your customers. I think you can see from some of the comments in this chain that people aren't so trusting as you feel you deserve.

And, of course, if someday you or the company needs the revenue, then it might be nice to have already, when not under duress, made a not easily-revocable decision about the ways you'll choose to monetize user data. Or, obviously, it might hamstring your plans.
