Matt Harding, the guy who travels around the world taking videos of people dancing with him, knows how to work the system without doing much work. First, he got Stride gum to sponsor his video-making trip around the world . Since the result went viral, he's milked his fame on the speaking circuit. First he made yet another "dancing" video at Yahoo's Sunnyvale headquarters . Last week, he spoke at nerdy-person gathering Gnomedex in Seattle. Watch his talk and learn all about how much — or rather, how little — work went into the popular "Dancing" video. Or, skip to 4 minutes in if all you're interested in is yet another crowd of people doing Harding's funny-looking jig.
