Lloyd F. Blitzer: The Rhetorical Situation

What is a rhetorical situation?  From what I gathered from this piece of writing, a rhetorical situation includes a response that fits the events at the time, creates responses that fit the events at the time, and a true rhetorical situation always has three main components which are exigence, audience and constraints.

Exigence, as defined by Mr. Blitzer, is an imperfection marked by urgency.  The audience is who the rhetorical situation is being applied to as in who is listening etc.  And constraints are anything that change the exigencies.  Mr. Blitzer stresses the importance that a good rhetorical speech will not only be applicable to present events but also that a rhetorical situation will create responses from the audience that are fitting to the events and content of the speech.  He gives a great example using President Johnson and the events that occurred during is presidency campaign.

I can't seem to figure out how this applies to digital media.  I felt that the reading was more fit for a philosophy class, but I did like how Lloyd Blitzer stated that most readers will think of the perfect thing to say after the fitting situation has passed.  It happens to me all the time.
