Facebook founder returns to Harvard

Mark Zuckerberg dropped out of Harvard University in 2004 to create what would become the world's largest social networking company, Facebook.

Earlier this week, Zuckerberg paid his first official visit to his alma mater since that time, and he has also started giving more public interviews.

Public relations executives think this is all part of rebuilding his image that was not put in the best light following the release of the hit film The Social Network, and the controversy surrounding the birth of Facebook.

Analysts also say a Mark Zuckerberg looking and interacting more as a chief executive, will no doubt help the company's valuation when it finally goes public
