What A History does well:
It establishes a historical context for those aspiring to become technorhetoricians.
It provides an extensive bibliography, with annotations within the text of some of the more important works.
It goes a long way to establishing computers and writing as a legitimate field of study.
It does not provide practical advice for teachers who are suddenly thrown into computer classrooms and need survival techniques.
It does not provide a blueprint for schools or English departments wishing to bring computer technology into their writing classes.
And, finally, it is truly not representative of what is happening in English classrooms or programs, any more than current rhetorical theory is truly representative of common practice; instead, it demonstrates by example what is possible when conditions are ripe for change.
