"There is a disparity between giving money so that others can continue to do work and being the one doing the work. I want that distinction clear, and to remain clear. The doctor who flew down to Haiti to personally help is infinitely more valuable than someone who donated."

Really? Let's say I donate enough money that the Red Cross can afford to send an additional doctor to Haiti. How is that not in the same ballpark as volunteering your time as a doctor to go work there?

We should care about the effects of our actions, and donating money to effective charities (see http://givewell.org) is one of the ways we can have the biggest positive effect.

(I take this seriously; I give about 1/3 of what I earn as a programmer to the most effective charities I can find.)
