I think this simplifies the reading process quite a bit. We may be
*able* to read in one dimension (ie., via a tickertape or DOW Jones
scrolling text) but a typical reading of a document includes a lot
more presentational information that provides context to the reader,
regardless of whether there is font size, weight, face or color
information present. For example, placement on the page and white
space is very important in delineating content types. Titles,
headers and footers, indenting and paragraph breaks, all these
things are included in almost any document type in order to assist
the reader in maintaining continuity, scannability, etc. (03)
For example, if I were to normalize the whitespace of this message
(including the mail header) and remove the paragraph breaks, the
ability to understand the flow of my ideas, where one subject ended
and the next began, would be compromised. I don't think of even
plain text documents as one dimensional, and really don't think
n-dimensional characterizations of media are particularly accurate
or useful, except in a relative sense (ie., this one is richer than
that one, etc.) (04)
