There are various techniques you can use to find podcasts out there. Some podcast readers, such as RSSRadio, let you search podcast directories. In RSSRadio, you can search by choosing Actions > Add a New Subscription > By URL, to open the Subscription Centre dialog, which gives you access to various podcast directories (Figure 7.21).

You can also search podcast directories directly; here's a starter list:
An especially cool one is www.podscope.com, which is sort of like Google for podcasts (Figure 7.23). Podscope actually listens to podcasts for you, and lets you search for the podcast you want based on a keyword.

For example, searching for the keyword weather gives you a multitude of podcasts to choose from (Figure 7.24).
