Givewell already analyzes the effectiveness of various charities, so I'd start there.
I don't agree with their emphasis on direct cash transfers. It reminds me of the Canadian Revenue Agency's statement that "preventing poverty is not charity, only relieving it." Givewell has always struck me as being more concerned about balancing one's karma than actually causing lasting improvement anywhere. That's just my perception, though.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
