Giving money to effective charities is one of the ways we can have the biggest positive impact in the world. If you've been thinking about giving to GiveWell's top-rated charity, the Against Malaria Foundation, but haven't gotten around to it, perhaps this will help: make a donation of up to $2K and I will match it 100%. I'll match up to $20K this way.

(Any money left over at the end of the year will also go to the AMF. That makes this a donor illusion, in that you're not actually affecting the amount I give them this year.)

Update 2013-02-08: I sent in $400 to match donations from ancientcampus and Adele_L.
