The Kickstarter distinction between investment/purchase is a bit blurry sometimes. What if I pledge $80 and Light Table becomes vaporware or development ceases?

The Kickstarter distinction between investment/purchase is a bit blurry sometimes. What if I pledge $80 and Light Table becomes vaporware or development ceases? Do I still get the t-shirt? At some point its inevitable that a big Kickstarter project will fail spectacularly. Those who gave money will be understandably angry. People will demand action from Kickstarter when in reality they have nothing to do with it. Will this change pledging habits and reward structures? Undoubtedly. Kickstarter themselves seem to be still testing the waters when deciding what projects are appropriate for their site. The approval process is done manually in house. Will this scale? I think eventually we'll see a number of smaller crowdsourcing sites pop up that are particular to certain product niches or investment types. GameKickStarter, MusicKickStarter, TravellingCircusKickStarter, MyStartupKickStarter. If this comes to fruition I think it will be great and allow consumers a better understanding and flexibility about how they want their money to be used. I look forward to seeing how new startups innovate in the crowdfunding space.
