The big Famecount 10 are in, and they taste like coffee and soda and candy. 6 of the 10 most popular brands on social media (Facebook, Twitter, and YouTube) are in the food and drink industry. Part of the draw comes from exclusives. Like Starbucks’ Barista badge on Foursquare, which gives customers the incentive to visit its outlets more often by awarding the “mayor” of each store with “$1 off a NEW however-you-want-it Frappuccino blended beverage. Any size, any flavor. Lasting until 6/28.”
