How to Live Anywhere in the World for Free

I recently wrote a popular post on how to travel for very cheap and stay at amazing exotic locations around the world in exchange for a bit of elbow grease in my post How To Live Anywhere In The World For Free. The post has been praised and criticized thoroughly and I thought I'd get some opinions from fellow bloggers. Again my aim was not to state that travel is free, but merely to point out how you can save a while ton of money and hit the road sooner than later. Let me know what you think!
