When @susan and I used the Vox blog service (from over a decade ago), we really enjoyed the daily prompts they created; it helped to write and be active.
I’ve thought of recreating that experience, but in a more timeless fashion, meaning we ask prompts and leave them there for others to find in the future.
And that’s it. No linking, no social graph. Just a thing to do or draw or write or whatevs, and then a person does something, and we don’t know, because thus is the nature of reality.
