Donations On Facebook?
Transferring money is now possible on Facebook. London-based ClickandBuy has created the Facebook application Buxter, which allows users to exchange money up to $68. While Buxter probably won’t be a tool used by campaigns to raise money on Facebook, it is a sign that Facebook will eventually become a medium through which campaigns can directly solicit donations.

I’m not sure how safe I feel about this! Given all of the privacy issues the Facebook has had, I don’t usually think of it as a secure medium for transferring money.
