The document discusses how various dance troupes, including Dance Theatre of Harlem and the San Francisco Ballet, are using social media platforms like YouTube, Facebook, Twitter, and their own websites to share their work, engage audiences, promote performances, and attract new followers and supporters. It provides examples of individual dancers like Maria Kochetkova of the San Francisco Ballet who have large Twitter followings and share behind-the-scenes glimpses into rehearsals and performances. The document advocates for dance troupes to more aggressively utilize social media to expand audiences and "demystify" ballet.
