This Blog Post by Mark Van Vlack, wherein he basically bemoans his relationship with Kickstarter ... I have this to say:
The point of Kickstarter is for you to vote with your wallet for things you want to see succeed... I would caution against viewing it as a means for you to get a good deal. It's concept is to democratize the process of venture capitalization via a low accountability network that relies on the good will of its membership. You could say it is the charitization of capitalism. You give for the sake of helping to bring things you like to market. Anything beyond that is icing on the cake. Mileage will vary. Batteries not included.
That's it. I hope it helps.
