[Stefik’s] four ideas about the Internet is that we think about Internet, number one as a library. And this was the 90s and we had this electronic library, the digital library. That doesn’t mean that we digitized libraries, it means that that’s the metaphor we used to think about the Internet, as a place that has information that we can look up. His second was we think of it as the mail. Or you could say the telephone. And so that’s more about individuals and interpersonally communicating in some way. The third is that we think of it as a virtual world. And the fourth is that we think of it as a marketplace.
