Dr. Andrew Cline, Rhetorica:
No blogger expends the energy to blog for no reason and for no audience. Humans do not speak for no reason. A rhetorical intention exists in every message–no matter how small or profound. Bloggers would do themselves and their causes far more good if they paid attention to kairos and accepted that what they really really want deep deep down is to move hearts and minds. Such acceptance might lead them away from an unthinking pathos to the light of reason (i.e. a proper balance of appeals).
Such realizations would allow them to sleep in, cogitate a bit more, and attack the keyboard with righteous (and proportional) anger when the time is right.
