Randi Zuckerberg

Randi Zuckerberg, who is director of marketing at Facebook and also the sister of CEO and co-founder Mark Zuckerberg, is leaving the company after six years to start a new-media firm to help companies become more social.
In her resignation letter, which is below in its entirety, Zuckerberg said:

"I have spent my years at Facebook pouring my heart and soul into innovating and pushing the media industry forward by introducing new concepts around live, social, participatory viewing that the media industry has since adopted. We have made incredible progress, but there is still much to be done and other ways I can affect change. Now is the perfect time for me to move outside of Facebook to build a company focused on the exciting trends underway in the media industry."

Mark Zuckerberg tops media power list .

Facebook founder Mark Zuckerberg has topped the Guardian's annual listing of the 100 most influential people in UK media.

Twitter co-founder Jack Dorsey was placed second, reflecting the growing power of social networking sites.
Their ascent comes at the cost of more traditional technology industry leaders, including Apple's Steve Jobs and Microsoft boss Steve Ballmer.
Experts from the fields of technology, PR and media helped compile the list.
Although social media figures occupied the two top spots, one of the medium's greatest advocates, prominent tweeter Stephen Fry, dropped out of the top 100.
