Yahoo! launched a new podcast search and subscribe service on last Sunday, marking the most significant development in the field since ipodder (now known as indiepodder http://www.indiepodder.org/). Yahoo! does podcasting a bit differently – “When you subscribe… you will be asked to download a small file called a .pcast file that contains information about the podcast. This file tells jukebox software like Yahoo! Music Engine, iTunes 5.0, and others to keep tabs on this podcast and to go fetch new episodes for you whenever they are ready.” The .pcast file looks almost exactly like an RSS file.
