Earlier quoted context omitted.
hard wrap at 72 characters seems pretty conservative
The reason it's 72 characters is to allow for quoted text, which gets indented relative to the new text. That would allow a line in an email that's 72 characters long to still fit within 80 characters if it's prefixed with 8 quote characters. For example: >>>>>>>>This line was 72 characters long, but is now 80 characters long instead.
Still looks pretty
bad on anything
less
than 72 characters
because there's
random
newlines in the
middle of
paragraphs.
Content should be
separated from
presentation.
Additionally 72
characters implies
monospace
fonts which have
been shown to be
less
readable.
