Did you read the "what is Kickstarter?" page before making this? Because Kickstarter isn't about pre-orders, its about backing projects. The "Kickstarter Is Not a Store" post on their blog is pretty clear about it all.

I'm not saying that an alternative browser for Kickstarter projects doesn't have merit. Or that a meta-directory sat on top of Kickstarter (and others) isn't a useful service. I'm just saying that your framing of it (pre-orders) is actually opposed to the ethos of the underlying service.
