I'd love to support protocol folks however I can. The requirements aren't super clear to me but I imagine:
  1. email as first class interface for the content (kind of like github issues)
    • you can read purely in email and write/comment purely from email
  2. digests
  3. economic self-moderation (which gets pretty hairy when people are communicating through email but we can figure it out)
Are there other things?
