He isn't your average information architect. Peter Morville, author of the book "Ambient Findability," recently fielded questions onlineabout the future of information and connectivity (Washington Post, free registration required). Morville touches on the issues of information authority, body hacks and interface design. The emphasis in his information technology is most definitely on information - where it is, what it is and how it's received.
He references, for example, this library science research from 1989, which illustrates how search is an "iterative and interactive" process: in the process of seeking information we are changed by the information we find.
Information heuristics have lead Kevin Kelly to proclaim information the new basis for science.
In contrast to the recent past we understand information not only as a thing, but also as a process. The notion of information-in-process suffuses the phenomenology of Martin Heidegger, the existential theology of Søren Kierkegaard and perhaps leads cosmologist and Templeton Prize winner John Barrow a bit closer to an understanding of the physics of nothingness and eternity.
"Heurists" - if it's not a word it should be - deepen understanding by developing information's first principles.
