Facebook plans 'professional networking'

LinkedIn, the social network for professionals, has recently raised $53 million in its latest round of investment and has been valued at a cool $1 billion. Not bad for the social network that many have pegged as 'boring' and 'straight'.

"We want to create a broad and critical business tool that is used by tens of millions of business professionals every day to make them better at what they do," said Dan Nye, LinkedIn's chief executive.
