It seems there is room for....

A website in the US about banks --why banks need to be reformed...calling for a specific set of policies, an advocacy/ educational/ even art project. That could be fun --an NGO about banking, finance, actually intervening and advocating and offering excellent explanation and alternatives.

An interesting model of such a website: bankwatch.org --feels grounded and thoughtful, credible. They are connected to brettonwoodsproject.org
