[From the about page] In The World Is Not a Desktop, Marc Weisner, the principal scientist and manager of the computer science laboratory at Xerox PARC, stated that, “a good tool is an invisible tool.” Weisner cited eyeglasses as an ideal technology because with spectacles, he argued, “you look at the world, not the eyeglasses.” Through repetition, and by design, technologies blend into our lives. While technologies, and communications technologies in particular, have a powerful mediating impact, many of the most pervasive effects are taken for granted by most users. When technology works smoothly, its nature and effects are invisible. But technologies do not always work smoothly. A tiny fracture or a smudge on a lens renders glasses quite visible to the wearer.
