>>the suggestion that its interference with effective communication was desireable<<

A) I never suggested that, and any such inference was completely outside my intended meaning.

B) Again, depending what and how one is trying to communicate, a little wit can say more in less space and provoke more related and interesting thoughts, than dry statement or words of new and obvious coinage. Although, the latter do seem, at least, to have the advantage of being memorable -- and, granted, sometimes funny in a camp or bawdy way.

C) Fun is not the opposite of serious.
