3. They are called "priestly" because at first when they have a new technology it is very expensive and he says there is a certain ignorance. The practitioners keep it to themselves at first and then gradually expand to some of the older accepted forms of communication.
5. Baron discusses fraud and authenticity so much because he thinks its a very important issue. These days anyone with a computer can put out any type of information into cyberspace he says.
