There is a conversation going on at Branch that you can join: What use do you think a non-profit site that rates corporate behavior based on stakeholder values would be? From the site:
"A crowdsourced site would allow people to contribute information about companies. The kind of metrics collected would be ratings on CEO pay (versus lowest paid employee), effect on environment, effect on community, etc. These metrics should be normalized as a simple 1-10 rating—easily publicized."
