Not a sealed envelope (that is encryption, a different problem), but a velvet rope: a room only members can enter, where the bouncer still has to recognize you to let you in.\n\nThis is a tour, with metaphors instead of acronyms. Why you lock the room instead of locking every post. Why the room is imaginary, and your data never leaves your own server. How a short-lived wristband lets a brand-new app gather a whole forum on your behalf. And why the door is kept deliberately boring, so the interesting rules can live up in the apps.\n\nIt includes a courier you can actually play with: hand it a wristband, watch it get bounced without one, flash an app ID badge at a picky club, and watch its wristband go stale mid-run.\n\nBuilt from Daniel Holmgren's Permissioned Data Diary and the official draft proposal."
