this story on News.com:
Alonovo.com lets people define the social and environmental values they feel are important and see how different merchants perform in those areas using data from KLD Research and Analytics. The areas include labor relations, animal rights, fair trade, charitable giving, clean-energy use and recycling, among others.
The sales are made through Amazon.com and buyers have access to merchants affiliated with that site.
I think this is really just the tip of the iceberg in terms of what we're going to see from Web 2.0. The data is already here, the infrastructure is already here, just build useful tools for different people and you'll be rewarded.
