More than half of Facebook users 'could quit the site over privacy worries'

Concerns about privacy are running so high that 60 per cent of the 1,588 Facebook users questioned by Sophos, a computer security organisation, said they were considering deleting their accounts on the social networking site. A further 16 per cent said they had already stopped using Facebook because they felt they had inadequate control over their data, while a quarter said that they would not be quitting the social networking site, which has almost 500 million users worldwide.
