Many people are using RSS feeds and feel acustomed to them but shy away from podcasts. I’am not sure why this is the case but tools like Juice Receiver could close this obvious gap. Podcasts are like radio shows, the only difference that they are not broadcasted but available as downloads mostly in mp3 format. The variety of themes excells those of radio shows in my opinion although tech podcasts are more common than, lets say, podcasts for women.
