Do you like podcasting?

Do you like podcasting? Do you know what a podcast is? You can go to itunes and download podcasts everyday. I always check the new ones and download them. They're like short information videos some are on keep fit, some business, some on fashion, culture, lifestyle. They can be about anything really. I'm thinking about doing my own podcasts and putting them on a site. I don't know the good sites yet though, I'll have to check it out. It's really easy you can even do a podcast with your webcam and microphone. It's a good way of advertising your business, or sharing your knowledge or just promoting yourself. Has anyone here done any podcasts of their own? Let me know, I'll check them out and I'll tell you when I've done some and where they are. now what shall I do my podcast about?...
