A must watch for those trying to understand Social Media. A lecture at Harvard given by Dan Zarrella, HubSpot social media scientist.

Dan attends many events where people share social media advice, most of it he calls ‘unicorns and rainbows’. Advice like engage in the conversation and reward your followers. Good advice hard to disagree with, but not based on anything substantial. Dan gets beyond the unicorns and rainbows, into the real data, the real science why people share online.

Plot: On a fall night in 2003, Harvard undergrad and computer programming genius Mark Zuckerberg sits down at his computer and heatedly begins working on a new idea. In a fury of blogging and programming, what begins in his dorm room soon becomes a global social network and a revolution in communication. A mere six years and 500 million friends later, Mark Zuckerberg is the youngest billionaire in history, but for this entrepreneur, success leads to both personal and legal complications.
