I strongly agree with mguelvp, I don't know the guy, I gave him $5 and I hold him no malice at all.
If you really care that strongly about your $30 (or however much it was) stop reading this and spend your time trying to get it back through a credit card charge-back. Maybe you will have success, maybe not. But what use is groaning on here?
Let's get it straight when you back a Kickstarter project you aren't an "investor" - you do not 'own' any part of the project or its creator. You have pre-ordered a product based on what is at best a video of a demo of a prototype. If they fail to deliver your rewards, then in a perfect world you should get your money back, but we all know that the world isn't perfect and you can kiss that money goodbye. At best you are an unsecured creditor, usually for a sum of money that it isn't worth chasing for.
Maybe others here feel the need to moan, phoning and demanding their money, or Google-stalk a project's creator because you want retribution for them making them feel foolish or stupid or something. Well, if you want to look like an real arse over a few dollars then go for it. Heck, if you care that much, spend real money and get an expensive lawyer to get you $30 back - and maybe it really will make you feel that much better.
I however have a more soul-uplifting view of Kickstarter. When I back a project on Kickstarter I like to think that am helping somebody have a go at realising one of their personal dreams. Sure, odds are that they may fail, or they might fall a little short, but at least they are willing to attempt it, and I am happy to spend a little of my pocket money to support them. If I get a product at the end of this then I am doubly happy - I helped somebody follow their dream and they made it happen!
So I might have not used my Parallella board much, or that Arduino Proto-shield much, and you may have a uCurrent sitting in a draw doing nothing. But I am sure that Andreas, Max & Duane and Dave really appreciate the fact that you helped to make it happen.
The people I can't understand is those who didn't back the project, and then still want to be involved - you know, the "see, I told you it was impossible" types. I am sure that most, if not all, of the backers understood that at the time of signing up. We are not all dumb or ill-informed people, we just wanted to see what happens - a bit of real life drama, watching people who can dream bigger dreams than us.
