A reminder for any readers thinking of donating to charity: you can get the most bang for your charity buck by (1) donating publicly, e.g. through Facebook Causes, to help promote norms of charitable giving -- making it psychologically easier for others to follow suit, and (2) donating to a meta-charity like GiveWell.
If you'd like to join me in donating to GiveWell through Facebook, just click here. If you're not a Facebook user, you can still donate to GiveWell here (and then blog about it, or leave a comment here, to help promote the norm). Thanks!
