Kickstarter is a place where awesome ideas find willing backers. If you choose to fund a thing, your money only gets taken if the project reaches an agreed upon level.
I love this idea, it gives you the ability to play shark tank, benefactor and godsend all in one click. You judge the presentations, and facts given and if an idea is worth it you can choose to donate to it. Most of the projects tell you the ROI, the return on investment. Projects ranging from Desktop Trebuchettes, Musicals named Coffee, Coffee Warmers and so many others.
