Yesterday I had the pleasure of meeting Clay Ward, founder of thoughtandmemory.org, an on-line resource for tracking supply chains and developing user-generated ratings of companies based on social and environmental performance. The site is built off a hefty back-end where anyone can contribute reviews of companies big and small, and the reviews get ranked by visitors to develop aggregate scores for each subsidiary and major corporation. ThoughtandMemory hopes to develop software so that shoppers can snap a digital picture of a product with their cell phone and receive a customized rating based on individual criteria. They are in the midst of grass-roots development and eager to involve as many readers and contributors to expand their database. The current campaign seeks to evaluate chocolate manufacturers, so if you can help in any way please contribute.
