@twitchhiker - Follow him and help him raise loads of money!!
I found this guy after reading about him in Metro last weekend.
He aims to travel around the world as far as possible only by means offered to him by people who follow him on Twitter. Travel, accommodation, anything. All has to be from his Twitter followers.
He's doing it all for charity so, I know there's a lot of Tweeters on here, get following him and help this guy out for a good cause.
Read more about his quest on his blog.
