I think most of these options could incorporate Steemit. For example, the Art-Reach interns could post on Steem about what they're doing, generating funds to pay next year's interns. The History Truck could post on Steem to continue generating revenue. That said, they also have immediate needs. Perhaps they could convert some Steem into USD and keep the rest to use as Steem power as a sort of investment into a new revenue stream.
Of course that's still running the risk of a big crash obliterating their Steem, and it seems like most NPOs are not willing to take that risk when they can barely afford to keep the lights on.
