1. Howcast - great place to learn how to do things visually. Very professional videos and easy to understand. Each video tells you what you need in advance.
2. YouTube - in addition to silly entertainment, they have good audiobooks and documentaries that the public has uploaded including my very own life experience channel: nmenterprise7
3. Blog Talk Radio - insightful podcasts, music programs. Here are a couple by friends of mine, one about marriage and the other with gospel music and interviews.
