I like the idea that people can use the Internet to noodle about with weird ideas. That's great.
What's not great is moving from "This is me, noodling about with my own personal weird idea, and here's the information so you can join in" to "Hey! I'm going to solve world hunger, and obesity, and you can live off this with no problems no matter who you are!!! (only $200 per month)"
Rest assured, if Ben and Jerry had a crowdfunding website and claimed their food was balanced for optimal nutrition I'd be very critical of them too.
