When an issue of grave importance arises, you've always had two choices: go one-man-against-the-world, or organize a band of your fellow aggrieved, torches and pitchforks optional. Go AngryMob 2.0, with The Point.
Born out of the helplessness of a guy bent over by his cellphone contract, TP uses the power of crowds to reach a "tipping point" on your matter of choice. Anyone can post a petition on just about anything, and indicate the amount of support necessary to attain goals both lofty ("Hugo Chavez, President of Venezuela, must sell CITGO or else we will boycott if 100,000 people join") and nerdy ("I will buy an office Wii if 15 people stay late to play each Friday"). For campaigns requiring cash, TP accepts c-cards, then holds the dough in escrow until the target's reached -- so people know that if it's not hit, the organizer won't abscond to Rio with money earmarked for recycling bins.
Other features: there's s a discussion section for pre-petition chatter (helpful for calculating tipping points on larger efforts), and a list of about-to-tip campaigns -- because while striking a blow for justice/communal gaming systems takes many, it's more satisfying when it takes Many + You.
