Podcasts allow you to listen in on conversations about topics of your choosing. They are usually pre-recorded and edited before being released as a downloadable audio file, which can be played at any time from anywhere with internet access. There are many different types of podcasts out there; some use solo hosts while others bring together panels or multiple voices into the discussion group. Podcasts typically have themed episodes too that focus on specific issues like politics, science fiction/fantasy literature, indie music reviews for example–you name it! The best part is they’re all free… well most of them, so you should definitely research some of your favorite topics to hear some pros elaborate and give you a little more insight.
