Put a target on an idea — “£150 and I'll make this” — and let your audience watch it fill up. A leaderboard tells people what is winning. A goal tells them what their next £5 actually does, and it turns backing an idea into finishing something rather than nudging it up a list. The board would show progress towards the target, tell you the moment one is reached, and let you close an idea to further boosts once it is funded so nobody pays into something already paid for.
