I'm going to kick in. I'm willing to spend some money just to help prove that croudfunded science can work. I understand why some are asking if this is the exactly correct study to do, but I'm not worried. A) I'm willing to trust the guy for $50, and B) once the market is established, competition will drive up study quality.
Some of it is funded by taxes. So are some businesses, and some art. That's all indirect support. Crowdfunding is direct support. Kickstarter has show that can work for businesses and art.
