Valentine's Day is a time for love, laughter and lots of smiles, which is something that Facebook wants a part in. Beginning February 13, Facebook will be introducing Valentine's Day cards with the option of sharing a card on a friend's Timeline or, if you're kind of sad, your own. The cards highlight Facebook's efforts to make the social media platform more warm and welcoming. The company has also introduced specific videos, like "Year in Review," Chinese New Year and its own birthday, coined as "Friends Day."
