Steve Kerrison writes "'There's little point in worrying about ID cards, RFID tags and spyware when more and more people are throwing away their privacy anyway. And the potential consequences are dire.' I've written an article on the dangers of social networks and how many users seem to forget just how public the information they post can be. This follows a warning sent out by the CS department of Bristol University, advising students that they risk lost job opportunities, getting in trouble with their parents and more, if they don't take care. The warning, however, really applies to all social network users, be they college students or over-zealous blog posters."
