Computers changed. They had graphics. They had things like folders and “point and click,” and people started to use word processors. When they used word processors, they stored their data. They typed into the word processor on a disk somewhere on a machine, which generally wasn’t accessible. So there was then a new frustration that data about these systems was available, but you had to log onto a special particular machine. You had to learn a particular program to access it. To find your way through the library was totally different from finding your way through the documentation system of an experiment. So the data was there, somewhere, going around and around on a disk, but it was really difficult to get at. So there was a mixture, a confluence of ideas, I suppose — the frustration that we didn’t have access to the data that existed, even though it was there — the need for a collaborative environment. I wanted something like Enquire, but where everybody could play, so that people working together could design something in a common shared space.
