I find the kickstarter projects interesting & inspiring and have supported a few and had no problems yet, the successful project is definitely the one where you get something physical for supporting a project, and alot of people use it for getting a business idea off the ground and some are just amazing raising 5 to 10 times what they were originally chasing - Makerbot was a classic to help the guys get started and then it allowed 3D printing to become a product that anyone could own not just the big company.
here is the link to the Aussie Kickstarter branch starting soon
