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.
So, Juice Receiver is a freeware program available for windows, mac and linux which has a large list of podcasts on board. It is very easy to surf the directory of podcasts available while subscribing to interesting ones with the click of the mouse. Song downloads are managed by the tool itself but playback comes from a media player that is installed on your system, Juice supports three players (itunes, winamp and media player), not sure what happens if you don’t have one of them installed on your system. You probably have to manually run the podcast then once it is downloaded.
Juice Receiver had some problems to connect to certain listings in the directory to receive a updated podcast listing, some were working, some not. This is most likely a temporary issue and should be resolved quickly. You may also add podcasts manually to Juice Reciever.
If you are new to podcasts give this tool a try, it offers a good introduction to podcasts and suggest some very interesting ones.
