The first thing to realize is that Internet-world is part of reality. The people you correspond with on the network are real people with lives and careers and habits and feelings of their own. Things you say on the net can make you friends or enemies, famous or notorious, included or ostracized. You need to take the electronic part of your life seriously. In particular, you need to think about and consciously choose how you wish to use the network. Regard electronic mail as part of a larger ecology of communication media and genres — telephone conversations, archival journals and newsletters, professional meetings, paper mail, voice mail, chatting in the hallway, lectures and colloquia, job interviews, visits to other research sites, and so forth — each with its own attributes and strengths. The relationships among media will probably change and new genres will probably emerge as the technologies evolve, but make sure that you don’t harbor the all-too-common fantasy that someday we will live our lives entirely through electronic channels. It’s not true.
