Conceptually, I can agree that usability is a continuum (or a scale, as Jared puts it). To the extent that a definition is possible, for the reasons Chauncey points out, I think we _must_ define it. Otherwise we have all the credibility of the ancient alchemist, shrouding our work in mystery and ultimately having it condemned as hokum.
The specific components or attributes of usability do vary from one project to another. But predictability, being partly intuitive (the user's responsibility) and partly experiential (the designer/programmer's responsibility), is a key attribute that moves us toward the side of the usability continuum. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
