Re: WTF is harlem shake?
Someone described why this went viral and I think he summed it up well:
1. Quick to watch, each one is just 30 seconds.
2. No language...no one speaks in the video so the whole world can understand it. And make their own video.
3. Easy to duplicate: A stationary camera, and 2 separate 15 second shots. A few minutes of video editing. That's it.
4. Randomness: You could pretty much do what you want, and it will be unique.
