One message on a public chalkboard. To replace it, you pay $1 more than whoever wrote it. The board is live. Whoever holds it last, wins.
When someone claims the chalk, we tweet it. Follow @ClaimTheChalk to watch the board change in real time — and see who's paying what to have the last word.
The first person pays a dollar to write anything on the board. Their message goes live instantly.
The next person pays two dollars to erase it. Their message replaces it. The old one goes to the permanent archive.
Every overwrite costs a dollar more. The price climbs forever. The board never runs out. Someone always wants the last word.
Messages get erased from the board, but nothing is lost. Every message, every price, every timestamp is preserved in a public, permanent archive.
The board is live. The price is climbing. The only question is what you'd write.
