Many of you who follow my blog are in academia or, at least, interested in such academic issues.  Michael Hyatt has an excellent post and a humorous video to depict what he means.  As a public speaker myself I regularly teach and lecutre to philosophy classes consisting of 25-250 students (250 is the regular size I teach).  I know every bit of what this video shows.  Some of them, of course, I have done myself and I can’t help but laugh.
