Ignore anyone who says they don't need cash. It's nonsense. Just turn your TV on for two minutes. We should be opening our wallets as much for Japan right now as we've done for any country facing this sort of crisis in the past.
It's just not clear to me how more cash will help. It seems that the major problems involve the logistics of getting rescuers and supplies to people who need them, and money isn't the limiting factor there. GiveWell seems to agree: http://blog.givewell.org/2011/03/15/update-on-how-to-help-ja...
