Digital words seem cheap because they are, and they grow cheaper by the day. Consider the withering hailstorm of mail, text, social net and blog posts that assaults you the moment you go online. It's become impossible for many a normal, solid citizen to answer his email promptly. But young people seem increasingly apt to ignore uninteresting messages on purpose. If the message is important it will be resent, and if it isn't, who cares anyway? So the value of digital words sinks even lower.
Somehow, I think it will all work itself out.
