It reassures me that kickstarter is actually being used to fund new things, rather than just as a marketplace for existing products, where you don't even have to have found any capital up front.
I hope that backers take it the same way. New stuff is risky by definition - and KS has funded some pretty major successes on risky projects too (Oculus).
It may not sound like much, but it is a benefit. I for one got a real kick out of seeing my name in Broken Age's credit roll.
I've backed quite a few Kickstarter projects and so far, none that were successfully funded have failed. Some still might and that would be disappointing, but I wouldn't regret backing them in the least. I have "bought" the fun of being a small part of something and watching things develop.
