Can writers live without the internet?

Well, I’m pretty taken with it but others seem even more attached. I’m not one of those people that are forever checking the phone for Tweets, emails and Facebook messages. If I’m out and about or teaching, the world can wait. However, at my desk or alone in a hotel or on a journey I’ll look at it all at regular intervals and both my mobile and my laptop alert me when a new email comes in – and my emails tell me if I have new Tweets or Facebook messages.
