CHAPTER 1
Introduction: A
Programmable Web
If you are like most people I know (and, since you’re reading this book, you probably are—at least in this respect), you use the Web. A lot. In fact, in my own personal case, the vast majority of my days are spent reading or scanning web pages—a scroll through my webmail client to talk with friends and colleagues, a weblog or two to catch up on the news of the day, a dozen short articles, a flotilla of Google queries, and the constant turn to Wikipedia for a stray fact to answer a nagging question.
All fine and good, of course; indeed, nigh indispensable. And yet, it is sobering to think that little over a decade ago none of this existed. Email had its own specialized applications, weblogs had yet to be invented, articles were found on paper, Google was yet unborn, and Wikipedia not even a distant twinkle in Larry Sanger’s eye.
And so, it is striking to consider—almost shocking, in fact—what the world might be like when our software turns to the Web just as frequently and casually as we do. Today, of course, we can see the faint, future glimmers of such a world. There is software that phones home to find out if there’s an update.There is software where part of its content—the help pages, perhaps, or some kind of catalog—is streamed over the Web. There is software that sends a copy of all your work to be stored on the Web. There is software specially designed to help you navigate a certain kind of web page. There is software that consists of nothing but a certain kind of web page. There is software—the so-called “mashups”—that consists of a web page combining information from two other web pages. And there is software that, using “APIs,” treats other web sites as just another part of the software infrastructure, another function it can call to get things done.
Our computers are so small and the Web so great and vast that this last scenario seems like part of an inescapable trend. Why wouldn’t you depend on other web sites whenever you could, making their endless information and bountiful abilities a seamless part of yours? And so, I suspect, such uses will become increasingly
