What Makes a Great Radio Presenter?

Authenticity matters a lot because many listeners know when you are not being real. They want to listen and learn from your experiences and if you are faking it, they will know. So, it's very important to be real, consistent, and above all, you should connect with your audience like you are talking to a friend. That kind of interaction is all you need to put your show up there. A lot of radio presenters go unprepared and that matters a lot because knowing your music, your topics, and your timing is of utmost importance. Who is your favorite presenter and why?
