Taxonomy of Conversation Styles

A reasonably simple, possibly crude, dichotomous taxonomy lies in what follows. Maybe these can serve as "tags"

Turn-based (Rounds) Conversations vs Round-less Conversations

Facilitated Conversations vs Not-facilitated Conversations

Moderated Conversations vs Un-moderated Conversations

Federated Conversations vs Not-federated Conversations

Dissertation vs Dialogue (h/t Ralph Barkow)
