Podcasts - radio made personal.

Podcasts are a great professional development resource. You find the series that you specifically want, subscribe, and each new episode is automatically downloaded to your computer. I know no better application to do this with than iTunes. Try searching in the iTunes store for 'digital musician' and you'll find my podcast series, about working in music.

These are all made with free applications - Audacity, Skype, Blogger, Feedburner and iTunes. Perhaps the most valuable feature of podcasts is your personal player; few of us have time to sit and listen at our computer to podcasts, but transfer them to your mp3 player and you turn tedious travel time into personal learning time.
