Emergence Speaks
We could start a conversation on collab.newstories.org called "Naming the forum!?" or similar. (And we might want to hide any existing conversations that aren't ready to happen.) It's easy to change the name of a conversation. Then we would have a repository for what we've tried, what we've thought, and so on.
I tried a loong list of domain names and arrived at EmergenceSpeaks.com (or .org). "Emergence Speaks" is relatively short compared to most others. "Speaks" is a present-tense action verb; emergence is speaking through the voices of the participants; etc. Emergence Speaks can apply to both online physical venues. Possibly a word like "forum" isn't needed if the name is impactful enough.
Emergence Speaks would seem to thread the needle in terms of the historical view (horizontal axis) of evolution and the insight of co-arising (vertical axis).
