Pleased to see that when asked about the relationship of FHI and SIAI, Nick gives the same answer I did.
I was the one who asked that question!
I was slightly disappointed by his answer - surely there can only be one optimal charity to give to? The only donation strategy he recommended was giving to whichever one was about to go under.
I guess what I'm really thinking is that it's pretty unlikely that the two charities are equally optimal.
