Besides visiting Directories, Communities or using iTunes, there are several alternative methods to finding, subscribing and consuming podcasts.
When it comes down to it a Podcast has two main parts. The Audio or Video file and a way of obtaining the file. Podcasters usually post their podcasts on their website offering several ways to obtain the media. Many podcasters will also offer quick subscribe buttons for iTunes and Zune users.
Via The Web
Podcasters usually post their podcasts on their website and offer a player to listen/view right from the site. In most cases there is no need for any media device, iPod or multi-media software. In fact many podcasters also report that this is the number one method that their shows are being consumed.
That same little orange icon responsible for blog subscriptions also works with podcasts. In fact many RSS readers such as Google Reader, support Podcast RSS feeds. You can also subscribe using a podcatcher. A podcatcher is an RSS reader specifically designed for podcasts and many times syncs with a media device. Most of these involve a simple process of right clicking (cntrl click on a Mac) the podcast’s RSS icon selecting “copy link location” and then pasting it (the copied link location) into the desired field on your podcatcher/rss reader. Once that has been set, the application will go to work retrieving the most recent podcasts associated with that RSS feed and will be updated with new podcasts when they become available.
