I've previously noted the norm-shaping importance of public giving, for which social-networking sites like Facebook seem especially well suited. The Facebook "Causes" application now makes this even easier, by encouraging users to make a "birthday wish" inviting their friends to donate to their preferred charity.
Today I get to make use of this new feature, picking GiveWell as my (meta-)charity of choice.
If you're a Facebook user, you can view my birthday wish here (and donate here). Or, if you don't use Facebook, feel free to donate directly to Givewell. Thanks!
