We have had to try to learn how to live in a world where at any moment we may be speaking to one other person or to millions around the world. The notion of private and public space has eroded. What we say in one place may be posted in another, not just for the whole world but for all time. And so we are having to find a way to speak and act online as though we may be speaking and acting in front of everyone – with the knowledge that if we slip up our error will be accessible everywhere and always.
