Actually, more failing projects should be funded IMO - Kickstarter has been too much like a store for too long, which caused a lot of people to have overly high expectations for projects they backed.
It doesn't help the perception that there are a lot of companies out there that seem to be using Kickstarter as a service for basically taking pre-orders though. Often I've thought "Why the heck is that big company with lots of money doing a Kickstarter? Isn't Kickstarter for people that wouldn't have the money to fund the project at all?".
A whole other debate, I know.
