Facebook has 20 million users worldwide, is worth billions of dollars and, if internet sources are to be believed, was started by the CIA.
The social networking phenomenon started as a way of American college students to keep in touch. It is rapidly catching up with MySpace, and has left others like Bebo in its wake.
But there is a dark side to the success story that's been spreading across the blogosphere. A complex but riveting Big Brother-type conspiracy theory which links Facebook to the CIA and the US Department of Defence.
The CIA is, though, using a Facebook group to recruit staff for its very sexy sounding National Clandestine Service.
Checking out the job adsdoes require a Facebook login, so if you haven't joined the site - or are worried that CIA spooks will start following you home from work -check them out on the agency's own site.
The story starts once Facebook founder Mark Zuckerberg had launched, after the dorm room drama that's led to the current court case.
Facebook's first round of venture capital funding ($US500,000) came from former Paypal CEO Peter Thiel. Author of anti-multicultural tome 'The Diversity Myth', he is also on the board of radical conservative group VanguardPAC.
The second round of funding into Facebook ($US12.7 million) came from venture capital firm Accel Partners. Its manager James Breyer was formerly chairman of the National Venture Capital Association, and served on the board with Gilman Louie, CEO of In-Q-Tel, a venture capital firm established by the Central Intelligence Agency in 1999. One of the company's key areas of expertise are in "data mining technologies".
Breyer also served on the board of R&D firm BBN Technologies, which was one of those companies responsible for the rise of the internet.
Dr Anita Jones joined the firm, which included Gilman Louie. She had also served on the In-Q-Tel's board, and had been director of Defence Research and Engineering for the US Department of Defence.
She was also an adviser to the Secretary of Defence and overseeing the Defence Advanced Research Projects Agency (DARPA), which is responsible for high-tech, high-end development.
