I don't see how this is of any benefit other than self-promotion...which isn't a bad thing for an entrepreneur, but I'd be willing to bet that the time it takes to worry about all the other daily needs has a net negative impact on your success when weighed against the publicity etc you receive. I think if your goal is to be "famous" for living in your car in the blogosphere etc, its a good way to do it, but to help you actually produce/build something.....not so much. GL either way.
Do you have an actual idea for a startup, or just looking for a cofounder then going from there?
