A very exciting book for me, because I see the complaints of the discontents as design challenges that can be overcome. The book contrasts the intimacy, transparency, and directness of “thinking with a pencil” to the helplessness and loss of connection inherent in black-box computational tools. I believe we can design a computational medium whose transparency and directness exceeds that of paper. It sure won't look like anything that exists today.
I suppose Turkle is also responsible for turning me on to scientific ethnography in general, along with Edwin Hutchins.
