To give a simple explanation, this concept replaces actual money for tweets in exchange for products. Tweets as currency isn’t exactly a new idea. In the past,  you have been able to pay for music and books through a tweet and now we’re seeing brands use it more often, Kellogg’s even had a whole shop dedicated to the concept! Most recently, Uniqlo have partnered with Starbucks to host a Twitter vending machine where a simple tweet from the device will get you a t-shirt.   Our UT Vending Machine will be exclusively at @StarbucksUK Conduit St, London this Friday 10th only! pic.twitter.com/Pmme9tOTL2…
