I've backed a bunch of Kickstarters, nothing big just a book, a bunch of video games, some miniatures, a few hot sauces, and a documentary. So far, 6 have fully delivered, one (one of the hot sauce ones) has partially delivered, the doc looks like it might potentially be vaporware (there're updates, but they've been really sparse lately), and I'm waiting on the remainder. Kickstarter is definitely a cool idea and I really do like it for labor of love projects, but you do have to be careful.
