What social media means to me is giving value. Listening to an audio and sharing what you have learned from it so that you can recommend it to others to listen to. No different than sharing what you have learned in a movie. People can feel your energy level based on what you read and based on what you heard. When you say it with passion then they will have a reason to go watch that good movie that you recommended or read that good book that you reccommended. All word of mouth!
