Flash mobbing was cool a few years ago. CarrotMobing is the new thing for 2009. Once again developed by people falling under what's referred to as the Generation G. (Twenty something aware of the socioeconomic realities the world is facing. Aspiring at living in a capitalistic way but in a more sustainable manner)

The movement was born on March 29, 2008, when hundreds of green-minded patrons poured into a San Francisco convenience store after Schulkin solicited bids from 23 stores in the area to find the business that would promise to spend the highest percentage of Carrotmob profits on more energy-efficient lighting. The crowd spent more than $9,200 at the K&D Market, which then fulfilled its pledge to plow 22% of the day's revenue into greener lighting — with the haul from the Carrotmob providing enough cash to make all the improvements recommended by an energy auditor (and Carrotmob supporter).
