Facebook Founder Unmasked on Twitter

A minority makes the experience more rewarding for the majority: Study

(NEWSER) - This might help explain why Facebook is closing in on 900 million users: Most people "receive more from their Facebook friends than they give," concludes a new Pew study . Among the findings from the one-month analysis:

• 40% of users made a friend request in the one-month period, but 63% received a request themselves
• Users hit the like button 14 times on friends' content, but received 20 likes on their own content in the same span
• 12% tagged a pal in a photo, but 35% were tagged by others

Experts offer healthy dose of skepticism

(NEWSER) - After Facebook's IPO filing on Wednesday, analysts are abuzz over a suggested $75 billion to $100 billion valuation. If the social network is to live up to the hype, it'll have to be "the next Google—or better," experts tell MSNBC . Opinions from around the web:

• Mark Zuckerberg's annual salary will fall to $1 in 2013, a la Steve Jobs, but this year he'll collect a $600,000 salary, an increase of $100,000 over last year. (Of course, salary, schmalary: He could be worth as much as $28 billion after the IPO; this year's salary is .002% of that amount.)

Mark Zuckerberg and his company aren't used to 'primetime scrutiny'

(NEWSER) - Facebook is finally on its way to becoming a public company, but are Mark Zuckerberg and crew prepared for what that truly means? Guardian columnist (and Newser founder) Michael Wolff has his doubts. "I don't think that Facebook, with its messianic ambitions and squirrelly zeal, is actually ready for the harsh light of public company life," he writes. "It has grown up in such a bubble of cultishness and doctrine, that primetime scrutiny could shortly become very uncomfortable." As a private company, Facebook has been able to stay largely "tightlipped" about everything from financing to privacy policies to its "data thirst." No more. More»
