If any of these sites will get bigger and end up with an oculus rift like success, where crowdfunders are sharing the company sale and sales success, then kickstarter (and all of the US-based clones who can't govern equity) will have a popularity drop. I mean, everyone will want to fund projects which give the product AND revshare.
