Valentine's Day has been taken over by Twitter and the cute idea behind Macy's Sweetest Tweets contest. Send out love-related tweets that are hashtagged #SweetestTweets and each day from February 1-February 13, Macy's will award a diamond pendant to the person who sends the sweetest tweet of the day. But on Feb 14 (ugh) a grand prize recipient will win a three-stone diamond ring worth $8,900! So be sweet, and start to Tweet!
