It’s the mid-90s, and I’m visiting a colleague’s house after work. He has an account with an Internet service provider; I don’t, and he has offered to show me what’s out there. So he fires up his computer, and we chat over the hiss, squawk, and chime of two modems flirting by phone. Once they’ve mated, they fall silent, and we turn our attention to the Netscape Navigator web browser. My pal has already discovered and bookmarked a number of sites on the World Wide Web that interest him. He shows me a few, and then I, impatient for a broader view, ask him if there’s a directory of some kind, like the ever-growing lists of computerized bulletin-board systems. How do you find a new place to go on the web, if you don’t know about it ahead of time? Simple, he says, taking us to a page with the excitable name “Yahoo!” at the top. The whole thing is simply a handcrafted list of other websites, organized into categories—just what we want.
