By linking your Twitter account with a credit card, Tweeple can send coffee to friends by tweeting at the user @tweetacoffee, then the Twitter handle of the friend you would like to receive a $5 e-gift card to Starbucks. As an additional incentive, the first 100,000 qualifying Visa card user that uses Tweet-a-Coffee will receive a $5 Starbucks e-gift card for themselves as well through November 6.
Users are already adopting the technology. A simple search of "tweetacoffee" on Twitter shows that users are send each other coffee and redeeming the gift cards.
Social media is making is continuously making it easier to manage our offline relationships online and Tweet-a-Coffee is just another example.

Would you use Tweet-a-Coffee? What would your reaction to receiving a gift card that can be used in the offline world through a digital means?
