Being unceremoniously dumped online isn't the only indignation made easier by social networks. For the first time, lawyers in the UK have been granted permission to serve a legal suit via Facebook. Traditionally, documents must be delivered physically, be it in person, by post or even fax. But, in a pretrial for a commercial dispute, these old-fashioned methods proved fruitless. The prosecuting team then decided to check online, and noticed recent updates on defendant Fabio De Biase's profile. Satisfied it was currently active, they sought permission to send documents via the website, with Justice Nigel Teare duly obliging. Wondering what that noise is? That's the sound of millions of mice clicking on "privacy settings" all at once.
