Came here to comment this. As it is, this seems like just talking on discord/telegram, but with the notion of publishing it later. What I really lack when discussing something is the ability to branch out and backtrack easily and have a view of all conversation topics at once.
That being said, I really like the idea of dialogues, and I think this is a push in the right direction, I have enjoyed the dialogue I read so far greatly. Excited to see where this goes
Thinking more on this and to friends who voiced that non-trees/dag dialog makes it non appealing to them also (especially in contexts where I was inviting them to have dialogue together), would there be interests in making a PR for this feature? I might work on this directly
