NYC creative Jeff Scardino created KillingCool for hacked-off creatives to share their frustration at great ideas being killed. The idea is that creatives discreetly open the mobile site during a meeting and add in the ideas that get stamped on. The numbers of ideas killed are tallied, and once you reach a certain number, you can claim rewards such as stickers, stationery and even original art, to help "heal the pain".
