Need to pass along an afternoon pick-me-up to a Twitter pal? Well, now you can do so with a tweet thanks to Starbucks. The coffee giant's "Tweet a Coffee" initiative allows for e-gifting $5 worth of joe with a mention of @tweetacoffee inside a 140-character message. Of course, you'll have to connect those Starbucks and Twitter accounts before composing for payment purposes. Could this be the start of widespread gifting via the tiny blue bird? Only time will tell. No word on when "Tweet a Cronut" will go live, though.
