Johnston blocks staff using Facebook

Allmediascotland has unearthed this memo sent to staff at The Scotsman which appears to show that Johnston Press has blocked journalists across the group from using Facebook.
It says:"A recent review has revealed that over 50 per cent of Johnston Press' outward internet traffic is to the social networking site, Facebook. The [Johnston] group has therefore decided....to block the site. Journalists who require access should seek approval from their departmental head, who should contact the Group Helpdesk to have the permission restored."
