Do you sell soda at your c-store or in your vending machines? In case you're interested, and if you think the world of social media has some sort of relevance to consumerism, you might find it interesting that according to Twitter, Coca-Cola has 2,154,352 followers and Pepsi Cola has 2,397,352 followers. Now, while Pepsi is the clear winner there, it should be noted that Diet Coke has 269,289 followers and Diet Pepsi has 68,074. RC Cola on the other hand? We couldn't find an official Twitter handle, but an unofficial one, found at twitter.com/RoyalCrownCola has a paltry 432 followers.
