I get annoyed by unnecessary hyphen-
ation in books or articles. My understand-
ing is that it happens when your soft-
ware is set to use paragraph justifi-
cation, so it tries to squeeze a per-
fact number of words in to each para-
graph so that the right margins are ex-
actly level. I sometimes convert art-
icles in to e-books, but never use Just-
ified mode, and don’t care if the right mar-
gins are ragged. I’ll always prefer read-
ability over some arbitrary desire for straight-
ness of margins.
