From Hemingway to every other self help book ever written, there's a recurring theme of the value of listening. As marketers, we can get too focused on the messages that we are trying to put out into the market, but the reality is that messaging isn't a one-way street anymore: brands grow and thrive because of advocates and evangelists (not static outbound messaging), consumers demand transparency and expect change to follow feedback. We need to get back to the basics of communication and listen to the feedback, the criticism, the jokes, and the trends. What we call social media listening is the process of hearing what is being said and responding to it, from replying to a tweet to rolling out a new app.
