People who post intimate details about their lives on the internet undermine everybody else's right to privacy, claims an academic. Dr Kieron O'Hara has called for people to be more aware of the impact on society of what they publish online. "If you look at privacy in law, one important concept is a reasonable expectation of privacy," he said. "As more private lives are exported online, reasonable expectations are diminishing."
The rise of social networking has blurred the boundaries of what can be considered private, he believes - making it less of a defence by law. We live in an era that he terms "intimacy 2.0" - where people routinely share extremely personal information online.
