When you enter the world of podcasting, you're stepping into a realm where anyone and everyone can have a voice and broadcast their opinions and imagination to the world. Have fun exploring, and perhaps you too may feel the urge to become a podcaster. If you do, it's easy. We've created a tutorial to tell you how.
Yahoo! Podcasts has everything you need to get started enjoying podcasts, including any software you might need. If you're currently setup for listening to podcasts, Yahoo! Podcasts works with the software you already have. So what are you waiting for!
