More importantly, I think the assumption is that the kickstarter is the only funding for the project, though Braff has also stated publicly that he is kicking in a lot of his own personal funds.
Bear in mind that there's also a signaling mechanism at work here. Lots of people on Internet forums will say, "I want to see Garden State II or Season 3 of popular TV show X" or whatever. But talk is cheap.
Kickstarter, however, lets people put their money where their mouths are: instead of saying, "I want to see or read X," you can say, "I want to see or read X so bad that I'm willing to pay $10 to make it happen." That $10 is much louder than 10,000 posts on the Internet.
