Guy travels half-way around the world for free using Twitter

A British journalist went the farthest a person could go from home -- from one end of the Earth to the other -- simply by relying on the kindness of strangers who were following him on Twitter.

Yeah, I know. I'm sick of hearing about Twitter, too. But if it can be used to make a dream like this come true, it's worth hearing about. Journalist Paul Smith set a course of Newcastle, England to Campbell Island, an island gateway to Antarctica, and a time limit of 30 days. He had a point to prove: that "kindness is universal" and "that social media may begin online but it will converge with the real world whenever and wherever you let it."
