To me an overriding consideration here is the not-only-meta consideration; people who want to become effective altruist donors in the future would be extremely well advised to give something today, even if it's only a small amount. The same applies on a much larger scale to effective altruism as a movement. It must be doing something today, preferably a good deal; for it to wait into the indefinite future is death as a movement, and not only because others, perhaps already on the fence, will be as suspicious as I am of the Indefinite Meta. There will be no future EA orgs if the EA orgs that exist today are not supported today. (This is also true within particular EA categories.)
