To he honest, I think this would better be done with Steem as main token. It’s a great on-boarding strategy for user growth, all while helping people getting those vital RC and then scale to other dApps.

Plus... it would give a constant stream of positive media.

But if it were a token it could be geared at 501s/NGOs and the value could be philanthropic. Usually I’m not a fan of philanthropy as a model but if tied in with actual org who have real plans and experience there could be better incentives for philanthropists than in the current systems.
