Not that I have any say in this at all, but as I understand it, Kickstarter is more for a defined project with an end date and specific goals that would be met. Would Funtoo, being a Linux distribution, qualify as that? Funtoo is an ongoing thing that will (hopefully) never see an end. What would backers be getting in return?
I could be entirely wrong, I don't know much about Kickstarter, but I'm not sure the format fits.
