I've always thought of American "non-profit" labels for orgs to he similar to the "democratic" label of the DDR or the "people's " republic of China, or all other "adjectives" that people put when they need others to believe their bullshit.
Interesting. Would you be able to list all of those that are not for profit? Just trying to make an informed decision, and I don't trust my google search - would rather get it from a fellow HNer.
