Hey, this is Yancey from Kickstarter here. We think projects like this are great, which is part of the reason we open-sourced the Amazon FPS code that we use at Kickstarter, which was then used in Selfstarter and Crowdhoster. It's on Github here: https://github.com/kickstarter/amazon_flex_pay
For us, Kickstarter is a big experiment and we're constantly learning what works, what doesn't, and making changes as we go. We want to provide the best possible space for creators to share their projects and for people to connect with them. We think we're doing a pretty good at that, but of course there's always more to learn.
