Taylor Swift is the biggest female singer in the world right now, and quite possibly one of the most accessible. Her 1989 global tour was filled with celebrity guests from supermodels, to singers, to professional sports players. But, if you’re a Swiftie singing in the audience or following from afar, Taylor very well might respond to your comments. Taylor is quite possibly one of the most savvy social media marketers in the business, understanding that the connections with individual fans are imperative and knows how to use each individual social media platform properly. She can start beef with fellow singers over award nominations or put out fires about dating rumors all in 140 characters or less.
