  There are studies - and I can't dig up the references right now either
  - which state that the "optimal" line length also varies with the type
  of material; narrow columns are good for newspapers; wider columns for
  books, and soforth.

  In addition - as Robert Bringhurst points out in his excellent "The
  Elements of Typographic Style" - the optimal line length in
  typography is considered to be 66 characters - for a single-column
  page set in a serifed text face. For multiple columns, 40-50 are
  better, 80-90 characters are really no problem for well-set pages, for
  justified text he recommends 40 (in English texts, that is), less than
  38-40 is not recommended, but for small doses of text 12-15 is
  acceptable.

  And THEN we complicate it with, for instance, the context. Old
  Egyptian scribes tended to write very wide columns of text
  (hypothesized that is because focus was on the *writing*, not the
  reading) ... 

  The more I learn about the way humans read and the way typography
  works to aid in that endevaour, the more I agree: leave the line
  length a variable to be easily adjusted by the user.
