Dialog and dialogue

The distinction between dialog and dialogue in my own writing is intentional. Although the terms in the dictionary are interchangeable, I have chosen to use them intentionally to help make clear when I am talking about merely communication, or a fragment of communication, versus that special form of communication which I mean by the use of the term dialogue. I mean to demonstrate that dialogue is not all communication, as some common use would have it, but when using that term I mean that special subset of communication which has the conditions and criteria I’ve outlined and talked about. Dialog can be still a bit ambiguous in that it means both a unit of speech and the medium of multidirectional communication in general, but I am satisfied with my distinction as being enough to operationally clarify my meaning when writing about dialogue as a discipline.
