Twitter and Facebook threaten spirit of Christmas, warns bishop He added that sending a handwritten message is now potentially a far more potent gesture than in the past as keyboards and tablets increasingly replace pen and paper. "There is nothing wrong with social media, I have a Facebook account and I really enjoy myself on Twitter but a hand signed and - even better - hand-delivered card conveys personal intention," he said. At Christmas I believe something has been lost by the trend away from sending cards. E-cards or a group email are OK, but they're no substitute for a hand-signed card through the letterbox. He added: "I know a lot of people including myself really value being able to write with a fountain pen, it feels personal. It is about quality now rather than quantity. "There is that phrase when asked "are you still in touch" -"only Christmas cards." "That is a start, better than nothing at all and if "only Christmas cards" ensures we do not lose touch with people completely that is good. But I think there is added value in handwritten messages.
