Well hello!! Here we are, finally, meeting in the virtual world of letters. I am looking forward to seeing what might occur in our dialogue through letters.
I am not sure how well I shall behave here. I am used to intersecting email monologues with commentaries, branching discussions through to finer and finer details. This has a structural fault. Two in fact. At least two that I have become aware of when I engaged my brother. We would have incredible depth and detailed discussions, but... First, we'd lose the whole view, the big picture, as we went into detail regarding a particular point. This would lead to the conversational elements, branches, being removed from their context, and they'd become useless and dead branches.
Second, there would be interesting patterns where different branches would link up, but there was no way to trace or track them. It was like looking at similar patterns at different levels of discussion. Conversations revealed a fractal nature. A serious wow, but beyond the capacity of the structure to reveal itself elegantly.
So, here we are, with a rather ham-fisted dialogue. My blurting few paragraphs, then yours, and so on, like taking turns in a board game. No accurate interruption. I suppose this allows for continuity of thought, but there is a missed opportunity.
Unless we write something that is less like a dialogue, less like a to-ing and fro-ing of information between two people, but where we are constructing something together, covering different faces of the same thing, shining light mutually, thus revealing something which is not only of interest to us, but to any other reader who may be interested. Let us suggest that if we collected these letters together, they could be transferred to a book relatively easily. If this is the case, then we need to be aware of it from the start. For example, in this context, this would be like an introduction, a preface, a period of preparation.
