Blue = the main mechanics / what users do on Twitter (the verbs: bookmarks, sense, discover, attend, reply, QT, be known, DM, request, etc.) and the gaps list
Red = failure modes, problems, critiques, things that don't work well ("curation leads nowhere", "not citable", "hard to catch up", "bad at memory", "unrecognized weak ties", "decision out of scope") AND principles/properties (the "rep Twitter cybernetics", "properties", "build modular tools", "AGENTS")
Pink/magenta = the facilitation/meta layer — "general clout too general", "how might we?", "routing & trust", "need to instill the right culture", "writing & chat" — these are the commentary on the system
Green = the meta-frameworks: OODA, STIGMERGY, ATP/D.G, gather/buy-in/moodmaking (the connective tissue concepts)
