How do we hide from the internet?
The High Court case against internet giants Facebook and Google to stop them from broadcasting an allegedly defamatory video shows what a goldfish bowl we live in.
While we are still debating the rights and wrong of a national identity card, the argument has moved on much further, through the worldwide broadcast of all kinds of personal photos, videos and comments.
Prospective employers check social network sites. Anyone can gather volumes of personal information with a simple trawl through the internet.
The 22-year-old DCU student who is taking the case is claiming the broadcast of the video in question could blight his career, and has taken injunctions against no less than eight social websites.
The number of sites involved in the High Court action underlines just how little anything that any of us does is safe from prying eyes.
