Women of Mass Influence - Sheryl Sandberg

Sheryl Sandberg - The elder in Facebook.

Facebook, the social networking giant, founded in a dorm room at Harvard University, is mostly young male software engineers working in a freewheeling culture.

Facebook recently hired Sandberg, former Google executive, to provide some adult supervision and help Silicon Valley's hottest startup to grow up - and make oodles of moola. If anyone can figure out how to capitalize on Web 2.0, it's has to be her. At Google, as vice-president of global online sales and operations, she oversaw huge growth in its international operations and managed its lucrative advertising business. As COO of Facebook, Sandberg will be a big influence on the expanding world of new media users as she scales Facebook operations and build its business model.

Already, many of us get great news content from sources like Beet.tv. And the way news are gathered and presented in Beet.tv is rather different from the normal staple. Journalism is redefined.
