Pledge
What it is
Commitments made to other people, kept visible. Something said out loud, recorded, and then shown to the person it was said to — so it stays a live obligation rather than a good intention that quietly lapses.
Where it is now
Built, and still finding its final shape. I am not going to pretend this one is finished: the idea is settled and the ground is laid, and it is on the near-ready shelf rather than in daily use.
Who it might interest
Anyone who has promised something to a friend and then remembered it three weeks too late.
