Yesterday, Facebook acquired Karma. An app for “in-the-moment gifting.” Using the app, you can browse through a virtual storefront to pick out a gift.
Once you’re found the perfect gift, you can create a virtual card and send your present to your recipient via text, email, or a message on his or her Facebook wall. As the person receiving the gift, you can choose to accept it -– and provide Karma with an address where you would like your gift shipped -– or you can trade the gift in for something else in Karma’s store. You can even choose to give the monetary value of the gift to charity.
Karma also reads through messages on your Facebook wall, and alerts you to specific events where you might want to send a gift.
